Description
Title of Invention: APPARATUS AND METHOD FOR
PROVIDING INTERACTION INFORMATION BY USING
IMAGE ON DEVICE DISPLAY
Technical Field
1111 Exemplary embodiments relate to an apparatus and method for displaying
an image
which relates to a potential interaction, such as, for example, a credit card
image, on a
display of a device, such as, for example, a lock screen of a mobile phone,
and
providing interaction information, such as, for example, settlement
information, which
is generated by using the displayed image.
Background Art
[2] As the mobile communication industry has rapidly developed, mobile
commu-
nication terminals are regarded as essential items. Accordingly, mobile
communication
terminals are equipped with various additional functions in addition to a
conventional
function, such as voice calling and data communication, thereby becoming multi-
functional terminals.
1131 Based on the above trend, technologies which relate to using a mobile
commu-
nication terminal as a payment means by storing information about a user's
credit card
in the mobile communication terminal are widely suggested. Further, as society
develops, payment means in various businesses have changed from cash to
various
types of credit payment means, such as credit cards. In addition, a reward
rate and a
discount rate may be variably applied, based on the type of payment means
being used.
[4] When a user wants to make a settlement by using a mobile communication
terminal,
it may be inconvenient to unlock the mobile communication terminal and
directly
operate a predetermined application. Further, in determining a credit card to
use for the
settlement of goods, it may be inconvenient for a user to check a reward rate
and a
discount rate of each credit card on an individual basis and to input
authentication in-
formation for settlement to a point-of-sale (POS) terminal.

[82] FIG. 1 is a block diagram which schematically illustrates an overall
concept of a
system in which a device 1000 transmits settlement information to a
counterpart device
2000, according to an exemplary embodiment. Referring to FIG. 1, the system
for
transmitting settlement information, according to the present exemplary
embodiment,
includes the device 1000, the counterpart device 2000, and a settlement server
3000.
The device 1000 is used to select an appropriate credit card based on a
settlement en-
vironment, and the device 1000 provides credit card information which relates
to the
selected credit card to the counterpart device 2000. A predetermined credit
card image
which is displayed on a screen of the device 1000 is selected by receiving a
touch input
from a user. As the device 1000 approaches the counterpart device 2000, and/or
as a
distance between the device 1000 and the counterpart device 2000 falls within
a prede-
termined range, the device 1000 may transmit settlement information which
relates to a
credit card which corresponds to the selected credit card image to the
counterpart
device 2000.
[83] In this case, at least one of a plurality of credit card images may be
displayed on a
lock screen of the device 1000. For example, at least one credit card image
may be
displayed on one of a plurality of unlock pattern points which are displayed
on a lock
screen of the device 1000. The unlock pattern points are points on a grid of
the lock
screen. Further, the device 1000 may recognize a fingerprint of a user based
on a user's
touch input, may unlock the device 1000 based on the recognized fingerprint,
and may
provide the recognized fingerprint information with settlement information to
the
device 1000.
[84] Further, the counterpart device 2000 may provide the received
settlement information
to the settlement server 3000 so that the settlement server 3000 may perform a
settlement via the device 1000.
[85] The device 1000 may be any one or more of a smartphone, a mobile
phone, a
personal digital assistant (PDA), a laptop computer, a media player, a global
po-
sitioning system (GPS) device. However, the present exemplary embodiment is
not
limited thereto, and the device 1000 may be other mobile or fixed computing
devices.
[86] Further, the counterpart device 2000 may be a point-of-sale (POS)
terminal, but the
present exemplary embodiment is not limited thereto. For example, the
counterpart
device 2000 may be any one or more of a smartphone, a mobile phone, a PDA, a
laptop computer, a media player, a GPS device, and other mobile or fixed
computing
devices.
[87] In another exemplary embodiment, the block diagram of FIG. 1 can be
understood as
representing a system for performing an interaction between a first user and a
second
user. The device 1000 can be understood as being associated with the first
user, and the
device 2000 can be understood as being associated with the second user.
Although the
11
CA 02876587 2014-12-12
WO 2014/030875 PCT/KR2013/007311
above-described exemplary embodiment refers to the interaction as being a
settlement,
other interactions may be performed.
[88] For example, a traveler may be preparing to fly on an airplane and may
need to check
in to obtain a boarding pass and/or to check baggage. In such a scenario, the
traveler
may be understood as being a first user, and the airline company may be
understood as
being the second user. The second device 2000 may be, for example, a kiosk at
the
airport, or a computer which is linked to the airline's web site on the
Internet. The
traveler may have a mobile phone which acts as a first device 1000, and the
mobile
phone may display images which correspond to items, such as, for example, a
passport,
a driver's license, and a personal credit card, which can be used for the
purpose of
checking in for the flight and/or checking baggage.
[89] As another example, a social media user may be preparing to upload
information
which relates to a recent experience. In this scenario, the social media user
may be un-
derstood as being a first user, and the second user may be the social media
web site.
The second device may be, for example, any terminal which may be used to
access the
social media web site. The social media user may have a mobile phone which
acts as a
first device 1000, and the mobile phone may display images which correspond to
items, such as, for example, photographs, text messages, and uniform resource
locator
(URL) links, which can be selectable for the purpose of uploading information
to the
social media site.
[90] FIG. 2 is a flowchart which illustrates a method by which the device
1000 transmits
settlement information to the counterpart device 2000, according to an
exemplary em-
bodiment. Referring to FIG. 2, in operation S200, the device 1000 displays a
credit
card image on a lock screen. In operation S200, the device 1000 may display a
credit
card image on at least one of the unlock pattern points which are displayed on
the lock
screen of the device 1000. The credit card image which is displayed on the
lock screen
may be used by the device 1000 to unlock the device 1000. Further, the device
1000
may display at least one credit card image without displaying the unlock
pattern points
on the lock screen of the device 1000.
[91] In operation S200, as a distance between the device 1000 and the
counterpart device
2000 falls within a preset range, the device 1000 may display a credit card
image on
the lock screen of the device 1000. For example, when the device 1000 has a
short
range communication connection with the counterpart device 2000 via near field
com-
munication (NFC), the device 1000 may automatically display a predetermined
credit
card image on the lock screen of the device 1000.
[92] Further, the device 1000 may display a plurality of credit card images
by arranging
the credit card images based on a predetermined standard. The device 1000 may
display a predetermined credit card image with emphasis.

[93] In operation S210, the device 1000 receives a user's touch input with
respect to a
credit card image. As a user touches a particular credit card image which is
displayed
on the lock screen of the device 1000, the device 1000 may receive the user's
touch
input.
[94] In operation S220, the device 1000 provides the counterpart device
2000 with
settlement information which corresponds to the received touch input, such as,
for
example, information which corresponds to the particular credit card image
which is
touched by the user. In operation S220, the device 1000 may extract credit
card in-
formation which relates to the credit card image touched by the user and user
in-
formation from a memory 1700 (see FIG. 14) of the device 1000, and may provide
the
extracted credit card information and the user information to the counterpart
device
2000. The credit card information may include, for example, any one or more of
in-
formation about a credit card number and a credit card expiration date, and
authen-
tication information about a credit card. The user information may include,
for
example, information about a user identification value and the date of birth
of a user.
[95] Further, in operation S220, the device 1000 may provide settlement
information to
the counterpart device 2000 when a touch input on a credit card image
continues or is
maintained over a predetermined time interval. When the device 1000 approaches
the
counterpart device 2000 within a time interval during which a touch input on a
credit
card image continues, the device 1000 may provide settlement information to
the
counterpart device 2000, but the present exemplary embodiment is not limited
thereto.
[96] In operation S220, the device 1000 may provide settlement information
to the
counterpart device 2000 when fingerprint information which is obtained as a
result of
receiving the touch input on a credit card image is effective.
[97] The flowchart of FIG. 2 may be also be applicable to other exemplary
embodiments.
For example, the flowchart of FIG. 2 may be applicable to the above-described
scenario of the traveler checking in for a flight and/or checking baggage for
a flight. In
operation S200, the traveler's mobile phone displays a respective image which
cor-
responds to each of a passport, a driver's license, and a credit card. In
operation S210,
the traveler provides a touch input to the mobile phone with respect to one of
the
displayed images. In operation S220, the mobile phone transmits the relevant
in-
formation regarding the selected item to the device 2000 which is used by the
airline
for completing the check-in and baggage check processes, e.g., a kiosk or a
link to the
airline's web site.
[98] Similarly, the flowchart of FIG. 2 can be applied to the above-
described scenario of
the social media user uploading information which relates to a recent
experience. In
operation S200, the social media user's mobile phone displays a respective
image
which corresponds to each of photographs, text messages, and URLs. In
operation
13
CA 02876587 2014-12-12
WO 2014/030875 PCT/KR2013/007311
S210, the social media user provides a touch input to the mobile phone with
respect to
at least one of the displayed images for a purpose which relates to the
upload. In
operation S220, the mobile phone transmits the relevant information regarding
the
selected item or items to the device 2000 which is used for performing the
upload, e.g.,
a computer terminal or a Wi-Fi connection at a hotspot.
[99] FIG. 3 is a flowchart which illustrates a method by which the device
1000 of FIG. 1
provides settlement information which corresponds to a touched credit card
image to
the counterpart device 2000, according to an exemplary embodiment. Referring
to FIG.
3, in operation S222, the device 1000 recognizes a fingerprint of a user when
the user's
touch input is received. The device 1000 may recognize a fingerprint of a user
from the
lock screen of the device 1000 by using a fingerprint recognition sensor (not
shown)
included in the device 1000. The fingerprint recognition sensor may be, for
example, at
least one of an optical sensor, a heat detection sensor, a condensing sensor,
and semi-
conductor type and/or electric field type sensors, but the present exemplary
em-
bodiment is not limited thereto.
[100] In operation S224, the device 1000 unlocks the device 1000 based on
the recognized
fingerprint. The device 1000 may compare the recognized fingerprint with
user's fin-
gerprint information which has previously been stored in the device 1000, and
may
unlock the device 1000 when the recognized fingerprint matches the user's
fingerprint
information as indicated with respect to a predetermined value.
[101] In this case, the user's fingerprint information may be stored in the
device 1000 to be
matched with each credit card image. The device 1000 may compare the
fingerprint in-
formation which corresponds to the touched credit card image with the
recognized fin-
gerprint.
[102] In operation S226, as the device 1000 is unlocked, the device 1000
executes an ap-
plication in order to transmit settlement information. The application
executed in
operation S226 may provide the counterpart device 2000 with information which
is
useful and/or required for performing a settlement.
[103] In operation S228, the device 1000 provides the counterpart device
2000 with
settlement information which relates to the credit card image selected by the
user's
touch input, via the executed application. The settlement information may
include at
least one of credit card information about the credit card image touched by a
user and
user information. The credit card information may include, for example, one or
more
of information about a credit card number and a credit card expiration date,
and au-
thentication information about a credit card. The user information may
include, for
example, information about a user identification value and the date of birth
of a user.
[104] In operation S229, the device 1000 provides the counterpart device
2000 with fin-
gerprint information about the recognized fingerprint. The device 1000 may
provide
14
CA 02876587 2014-12-12
WO 2014/030875 PCT/KR2013/007311
the counterpart device 2000 with the fingerprint information via the executed
ap-
plication. Further, the counterpart device 2000 may provide the settlement
server 3000
with the received fingerprint information and may perform a settlement.
111051 FIG. 4 is a flowchart which illustrates a method by which the device
1000
recommends a credit card to be used for settlement based on a settlement
environment,
according to an exemplary embodiment. Referring to FIG. 4, in operation S200,
the
device 1000 stores credit card information and credit card benefit
information. The
device 1000 may store information about a credit card possessed by a user
based on a
user input. The credit card information may include, for example, information
about
any one or more of a credit card type, a credit card number, and a credit card
expiration
date. Further, the device 1000 may receive credit card information from the
settlement
server 3000 and store the received credit card information. The settlement
server 3000
may be a server operated by a credit card company, but the present exemplary
em-
bodiment is not limited thereto. In this case, the device 1000 may provide the
settlement server 3000 with user profile information which is stored in the
device
1000, and may receive credit card information which corresponds to the user
profile in-
formation provided by the settlement server 3000. In addition, when a user
possesses a
newly issued credit card, the device 1000 may receive credit card information
about
the newly issued credit card.
111061 The device 1000 may store credit card benefit information for each
credit card stored
in the device 1000 based on a user input. The device 1000 may provide a user
interface
to facilitate an input of credit card benefit information. A user may input
credit card
benefit information for each credit card which is stored in the device 1000
via the user
interface. Further, the device 1000 may receive credit card benefit
information from
the counterpart device 2000 and may store the received credit card benefit
information.
The credit card benefit information received from the counterpart device 2000
may
include information about benefits provided when a settlement is made through
the
counterpart device 2000. The device 1000 may receive the credit card benefit
in-
formation from the settlement server 3000 and may store the received credit
card
benefit information.
111071 The credit card benefit information may be stored by being matched
with a credit
card. For example, the credit card benefit information may include any one or
more of
price discount information, points reward information, and coupon information.
Further, the credit card benefit information may include information about
various
benefits according to a membership store where a credit card is used.
111081 In operation S205, the device 1000 stores the user's credit card use
history. The credit
card use history may include, for example, any one or more of a credit card
number
used for settlement, a settlement time, a settlement date, the name of a
membership
15
CA 02876587 2014-12-12
WO 2014/030875 PCT/KR2013/007311
store, a settlement position, the name of goods, and information about
benefits
provided for settlement using a credit card. When a user performs a credit
card
settlement via the device 1000, the device 1000 may store use history of a
credit card
used for a settlement, but the present exemplary embodiment is not limited
thereto.
The credit card history information about the settlement through the device
1000 is ac-
cumulated and stored in the settlement server 3000. The device 1000 may
receive the
credit card history information stored in the settlement server 3000 from the
settlement
server 3000.
[109] In operation S210, the device 1000 obtains information about a
settlement en-
vironment. When a user tries to perform a settlement using a credit card via
the device
1000, the device 1000 may obtain information about a settlement environment
from at
least one sensor in at least one of the device 1000, the counterpart device
2000, and the
settlement server 3000. The information about a settlement environment may
include
information about any one or more of a settlement time, a settlement position,
a
membership store, and goods.
[110] In detail, the device 1000 may obtain information about the position
of the device
1000 and may determine which membership store is suitable for performing a
settlement based on the obtained position information. For example, the device
1000
may determine a GPS value with respect to the position of the device 1000 by
using a
GPS sensor (not shown). The device 1000 may determine an identification value
of an
access point (AP) which is connected to the device 1000. Further, the device
1000 may
determine a membership store where the device 1000 is located based on at
least one
of the GPS value and the AP identification value. In this case, information
about the
membership store corresponding to the GPS value and the AP identification
value may
have been previously stored in the device 1000 or a separate server (not
shown).
[111] The device 1000 may check goods information about goods that are
subject to a
settlement. The device 1000 may check goods information via a marker which
attached
to the goods, but the present exemplary embodiment is not limited thereto. The
device
1000 may check goods information from the counterpart device 2000. The device
1000
may receive at least one of a date, a time, an identification value of goods,
an amount
of goods, and an identification value of a membership store which corresponds
to the
counterpart device 2000, but the present exemplary embodiment is not limited
thereto.
[112] The device 1000 may check any one or more of a points reward rate, a
points reward
limit, a discount rate, and a discount limit for each credit card based on
information
about a membership store and goods. Information about a points reward rate, a
point
reward limit, a discount rate, and a discount limit with respect to a
membership store
and goods may have previously been stored in the device 1000 or the separate
server.
111131 In operation S220, the device 1000 is used to select a credit card
to be used for
16
CA 02876587 2014-12-12
WO 2014/030875 PCT/KR2013/007311
performing a settlement based on the settlement environment. The device 1000
may
determine a credit card to be used for performing a settlement in the obtained
settlement environment by using at least one of credit card information,
credit card
benefit information, and a settlement history.
[114] In detail, the device 1000 may extract a credit card which has been
used more than a
preset number of times in the obtained settlement environment based on the
credit card
settlement history. For example, if a credit card A, a credit card B, a credit
card C, and
a credit card D are used in a membership store A and the membership store
included in
the obtained settlement environment is the membership store A, the device 1000
may
extract the credit card A, the credit card B, the credit card C, and the
credit card D
from the credit card information. Further, for example, if the credit card A
and the
credit card C have been used in the membership store A on more than a preset
number
of occasions and the membership store included in the obtained settlement en-
vironment is a membership store A, the device 1000 may extract the credit card
A and
the credit card C from the credit card information.
[115] For example, if the credit card A, the credit card B, the credit card
C, and the credit
card D are used in a time slot "11:00 ?14:00" and the settlement time which is
included
in the obtained settlement environment is within the time slot "11:00 ?14:00",
the
device 1000 may extract the credit card A, the credit card B, the credit card
C, and the
credit card D from the credit card information. Further, for example, if the
priorities of
the credit card A and the credit card B are higher among the credit cards used
in the
time slot "11:00 ?14:00" and the membership store included in the obtained
settlement
environment is the membership store A, the device 1000 may extract the credit
card A
and the credit card B from the credit card information. In this case, the
priority of a
credit card may be determined based on at least one of a preset standard
and/or a user
input. In addition, although the priority of a credit card may be determined
by re-
flecting the benefit for each credit card, the present exemplary embodiment is
not
limited thereto.
[116] Further, the device 1000 may extract a credit card based on one or
more of a plurality
of items which are included in the settlement history and the settlement
environment.
In this case, the device 1000 may determine a credit card to be extracted from
the
obtained settlement environment by applying a predetermined weight to each
item
included in the settlement history and the settlement environment and by
considering
the weights of the items.
[117] In operation S225, the device 1000 recommends at least one of a
plurality of credit
cards to be used for performing a settlement based on the credit card benefit
in-
formation. The device 1000 may compare benefits of the extracted credit cards
based
on the credit card benefit information, and may recommend credit cards based
on a
17
CA 02876587 2014-12-12
WO 2014/030875 PCT/KR2013/007311
result of the comparison. The device 1000 may determine credit cards for a
recom-
mendation based on, for example, the type of credit card benefits a user
prefers, and/or
the amount of credit card benefits calculated into cash. The device 1000 may
display,
on the screen, information about benefits provided by each credit card, and
thus a user
may select a credit card based on the displayed benefit information.
[118] In this case, the device 1000 may receive the credit card benefit
information from the
settlement server 3000. The device 1000 may transmit the information about a
credit
card which information is stored in the device 1000 to the settlement server
3000, and
may receive the credit card benefit information from the settlement server
3000, but
the present exemplary embodiment is not limited thereto.
[119] The device 1000 may receive the credit card benefit information from
a terminal (not
shown) of a store. In this case, the terminal of a store may transmit
information about a
type and benefits of a credit card that are provided by the store, to the
device 1000 in
the store. The terminal of a store may provide the benefit information to the
device
1000 via, for example, SMS/multimedia messaging service (MMS), but the present
exemplary embodiment is not limited thereto. Further, the terminal of a store
may
provide the benefit information to the device 1000 via a wireless fidelity
(WiFi)
network.
[120] Further, the device 1000 may automatically select a credit card to be
used for a
settlement based on a display mode, or may select the credit card based on a
user input.
[121] The device 1000 may display a list of recommended credit cards for
performing a
settlement on the lock screen of the device 1000. For example, an image of a
rec-
ommended credit card may be displayed on a pattern lock point on the unlock
screen
of the device 1000, but the present exemplary embodiment is not limited
thereto.
[122] In this case, when a user selects a credit card image which is
displayed on the lock
screen, a user interface which prompts to input a personal identification
number (PIN)
of a selected credit card may be displayed, but the present exemplary
embodiment is
not limited thereto. When the user touches a credit card image which is
displayed on
the lock screen, the device 1000 may recognize a fingerprint of the user based
on the
user touch input and may unlock the device 1000 based on the recognized
fingerprint
and perform a settlement.
[123] Further, when the user selects a credit card image which is displayed
on the unlock
screen, the user may be approved and/or authenticated based on a user image
and
voice. For example, the device 1000 may capture a user's face and determine
whether a
captured user is a true holder of the credit card which is displayed on the
unlock
screen. In addition, for example, the device 1000 may approve and/or
authenticate a
user by recognizing the iris of the user. Still further, for example, the
device 1000 may
record the voice of a user and may approve and/or authenticate the user based
on the
18
CA 02876587 2014-12-12
WO 2014/030875 PCT/KR2013/007311
recorded voice.
[124] When a user selects a predetermined credit card from the credit card
recommendation
list, a settlement window which relates to the selected credit card may be
displayed on
the screen of the device 1000. The settlement window which is displayed on the
screen
of the device 1000 may include, for example, any one or more of credit card in-
formation, coupon information, a settlement amount, and a PIN code input
field.
Further, when the user inputs a PIN code of the selected credit card in the
PIN code
input field, a settlement using the selected credit card may be approved.
[125] When the settlement using the selected credit card is safely
performed, a part or the
whole settlement window may be displayed in a preset color. The device 1000
may
check whether the settlement information about the selected credit card may be
transmitted to the counterpart device 2000 and the settlement server 3000 and,
when
the settlement information can be safely transmitted, the settlement window
may be
displayed in a color which is preset by the user. The device 1000 may check
whether
the settlement information about the selected credit card may be safely
transmitted to
the counterpart device 2000 and the settlement server 3000 by receiving
separate au-
thentication information from the counterpart device 2000 and the settlement
server
3000. However, the present exemplary embodiment is not limited thereto.
[126] FIG. 5 is a flowchart which illustrates a method by which the device
1000 of FIG. 1
arranges and displays credit card images on a lock screen, according to an
exemplary
embodiment. Referring to FIG. 5, in operation S202, the device 1000 may
receive in-
formation about a least one of credit cards that are usable for performing a
settlement
from the counterpart device 2000. In operation S202, when a distance between
the
device 1000 and the counterpart device 2000 falls within a preset range, the
device
1000 may receive the information about the at least one of credit cards that
are usable
for performing a settlement from the counterpart device 2000. The information
about
the at least one of credit cards that are usable for performing a settlement
may include,
for example, information about any one or more of a type of a credit card, a
points
reward rate of a credit card, and a discount rate of a credit card, but the
present
exemplary embodiment is not limited thereto.
[127] In operation S204, the device 1000 may arrange credit card images on
the lock
screen of the device 1000 based on at least one of the points reward rate and
the
discount rate. For example, the device 1000 may arrange a credit card having a
higher
points reward rate or a higher discount rate prior to a credit card having a
lower points
reward rate or a lower discount rate.
[128] Further, the device 1000 may arrange a credit card which matches the
position of the
device 1000 prior to a credit card that does not match the position of the
device 1000,
based on the position of the device 1000. For example, the device 1000 may
display a
19
CA 02876587 2014-12-12
WO 2014/030875 PCT/KR2013/007311
credit card K when the device 1000 is located at a membership store A. In
addition, for
example, when the device 1000 is located at a membership store B, the device
1000
may primarily display a credit card H. In this case, position information may
include at
least one of a GPS value and an identification value of an AP connected to the
device
1000, but the present exemplary embodiment is not limited thereto. Still
further, the
device 1000 may determine a store where the device 1000 is located, based on
the GPS
value and the identification value of an AP connected to the device 1000. In
this case,
an identification value of a store that matches at least one of the GPS value
and the
identification value of an AP connected to the device 1000 may have previously
been
stored in the device 1000.
[129] When credit card images are arranged based on the position of the
device 1000,
operation S202 may be omitted. In this case, the information about a credit
card that is
usable at a store which corresponds to the position of the device 1000 may
have
previously been stored in the device 1000.
[130] Further, the device 1000 may arrange credit card images on the screen
of the device
1000 based on at least one of the number of uses of a credit card by a user
and user
preference. For example, the device 1000 may primarily display a credit card
having a
relatively higher number of uses, and may secondarily display a credit card
having a
relatively lower number of uses. Still further, for example, the device 1000
may
primarily display a credit card having a relatively higher user preference,
and may sec-
ondarily display a credit card having a relatively lower user preference. The
user
preference may be calculated by executing any one or more of various
algorithms
which may be based, for example, on the number of uses of a credit card and a
settlement amount of a credit card.
[131] FIG. 6 is a flowchart which illustrates a method by which the device
1000 of FIG. 1
distinctively displays credit card images on a lock screen with emphasis,
according to
an exemplary embodiment. Referring to FIG. 6, in operation S206, the device
1000
may receive information about a credit card that is usable for performing a
settlement
from the counterpart device 2000. In operation S206, when a distance between
the
device 1000 and the counterpart device 2000 falls within a preset range, the
device
1000 may receive the information about a credit card that is usable for
performing a
settlement from the counterpart device 2000. The information about a credit
card that
is usable for performing a settlement may include, for example, information
about any
one or more of a type of a credit card, a points reward rate of a credit card,
and a
discount rate of a credit card, but the present exemplary embodiment is not
limited
thereto.
[132] In operation S208, the device 1000 displays, with emphasis, a credit
card that is
usable for performing a settlement, based on a predetermined standard. In
operation
20
CA 02876587 2014-12-12
WO 2014/030875 PCT/KR2013/007311
S208, the device 1000 may display with emphasis a credit card that is usable
for
performing a settlement on the lock screen of the device 1000. For example,
the device
1000 may display the credit card that is usable for performing a settlement by
changing
the color of a credit card image which corresponds to the credit card, or by
increasing
the thickness of an edge of a credit card image. Further, the device 1000 may
display
the credit card by changing the color of a pattern lock point or the thickness
of an edge
of a pattern lock point on which the credit card that is usable for performing
a
settlement is located.
[133] In operation S208, the device 1000 may display with emphasis a
predetermined
credit card image based on at least one of the points reward rate and the
discount rate.
For example, the device 1000 may display with emphasis a credit card having a
high
points reward rate and a high discount rate.
[134] The device 1000 may display with emphasis a credit card which matches
the position
of the device 1000 based on the position of the device 1000. For example, the
device
1000 may display a credit card K with emphasis when the device 1000 is located
at a
membership store A. Further, for example, when the device 1000 is located at a
membership store B, the device 1000 may display a credit card H with emphasis.
In
this case, position information may include at least one of a GPS value and an
identi-
fication value of an AP connected to the device 1000, but the present
exemplary em-
bodiment is not limited thereto. Still further, the device 1000 may determine
a store
where the device 1000 is located, based on the GPS value and the
identification value
of an AP connected to the device 1000. In this case, an identification value
of a store
that matches at least one of the GPS value and the identification value of an
AP
connected to the device 1000 may have previously been stored in the device
1000.
[135] When the credit card image is displayed with emphasis based on the
position of the
device 1000, operation S206 may be omitted. In this case, the information
about a
credit card that is usable at a store which corresponds to the position of the
device 1000
may have previously been stored in the device 1000.
[136] Further, the device 1000 may display with emphasis credit card images
based on at
least one of the number of uses of a credit card by a user and user
preference. For
example, the device 1000 may display with emphasis a credit card having a
relatively
high number of uses. Still further, for example, the device 1000 may display
with
emphasis a credit card having a relatively high user preference. The user
preference
may be calculated by executing any one or more of various algorithms which are
based
on the number of uses of a credit card and a settlement amount of a credit
card.
[137] FIG. 7 is a block diagram which schematically illustrates an example
of displaying a
recommended credit card when a distance between the device 1000 and the
counterpart
device 2000 falls within a predetermined range, according to an exemplary em-

WO 2014/030875 PCT/KR2013/007311
the credit card image by changing the color of a pattern lock point which is
displayed
under a credit card that is usable for performing a settlement, or by
increasing the
thickness of an edge of the pattern lock point.
[159] The credit card image arrangement unit 1200 arranges credit cards
that are usable for
performing a settlement according to a predetermined standard. The credit card
image
arrangement unit 1200 may arrange credit card images according to a
predetermined
standard by using information about the credit card image that is usable for
performing
a settlement. In this case, when a distance between the device 1000 and the
counterpart
device 2000 falls within a present range, the device 1000 may receive the
information
about the credit card that is usable for performing a settlement from the
counterpart
device 2000. The information about the credit card that is usable for
performing a
settlement may include, for example, information about any one or more of a
type of a
credit card, a points reward rate of a credit card, and a discount rate of a
credit card,
but the present exemplary embodiment is not limited thereto. The credit card
image ar-
rangement unit 1200 may recommend a plurality of credit cards to be used for a

the position of the device 1000 in a primary manner, as compared to credit
cards that
do not match the position of the device 1000, which may be arranged in a
secondary
manner, based on the position of the device 1000. For example, the credit card
image
arrangement unit 1200 may primarily arrange a credit card K when the device
1000 is
located at a membership store A. Further, for example, when the device 1000 is
located
at a membership store B, the device 1000 may primarily arrange a credit card
H. In this
case, position information may include at least one of a GPS value and an
identi-
fication value of an AP connected to the device 1000, but the present
exemplary em-
bodiment is not limited thereto. In addition, the credit card image
arrangement unit
1200 may determine a store where the device 1000 is located, based on at least
one of
the GPS value and the identification value of an AP connected to the device
1000. In
this case, an identification value of a store that matches at least one of the
GPS value
and the identification value of an AP connected to the device 1000 may have
previously been stored in the device 1000. The information about the credit
card that
may be used at a store which corresponds to the position of the device 1000
may have

26
CA 02876587 2014-12-12
WO 2014/030875 PCT/KR2013/007311
not limited thereto.
[162] The credit card image arrangement unit 1200 may arrange credit card
images on the
lock screen of the device 1000 based on at least one of the number of uses of
a credit
card by a user and user preference. For example, the credit card image
arrangement
unit 1200 may primarily arrange a credit card having a relatively higher
number of
uses with respect to a secondary arrangement of a credit card having a
relatively lower
number of uses. In addition, for example, the device 1000 may primarily
arrange a
credit card having a relatively higher user preference with respect to a
secondary ar-
rangement of a credit card having a relatively lower user preference. The user
preference may be calculated by executing any one or more of various
algorithms
which may be based on the number of uses of a credit card and a settlement
amount of
a credit card.
[163] The user input receiving unit 1300 may receive a touch input from a
user which
respect to a credit card image. When a user touches a predetermined credit
card image
which is displayed on the lock screen of the device 1000, the user input
receiving unit
1300 may receive a user touch input.
[164] The fingerprint recognition unit 1400 may recognize a user's
fingerprint based on a
received touch input. The fingerprint recognition unit 1400 may recognize a
user's fin-
gerprint from the lock screen of the device 1000 by using the fingerprint
recognition
sensor included in the device 1000. The fingerprint recognition sensor may be,
for
example, at least one of an optical sensor, a heat detection sensor, a

and semiconductor type and electric field type sensors, but the present
exemplary em-
bodiment is not limited thereto.
[165] The unlocking unit 1500 may unlock the device 1000 based on the
recognized fin-
gerprint. The unlocking unit 1500 may compare the recognized fingerprint with
user-
specific fingerprint information which has previously been stored in the
device 1000,
and may unlock the device 1000 when the recognized fingerprint matches the
user-
specific fingerprint information as indicated with respect to a predetermined
value.
[166] In this case, the user-specific fingerprint information may be stored
in the device
1000 to be matched with each credit card image. The unlocking unit 1500 may
compare the fingerprint information which corresponds to the touched credit
card
image (i.e., the received touch input) with the recognized fingerprint.
[167] When the device 1000 is unlocked, the settlement information
providing unit 1600
may provide settlement information which corresponds to the credit card image
touched by a user to the counterpart device 2000. In particular, when the
device 1000
is unlocked, the settlement information providing unit 1600 may execute an
application
in order to transmit settlement information. The settlement information
providing unit
1600 may provide the settlement information to the counterpart device 2000 by
using
27
CA 02876587 2014-12-12
WO 2014/030875 PCT/KR2013/007311

[168] The settlement information providing unit 1600 may extract, from the
memory 1700,
user information and credit card information about a credit card image touched
by a
user, and may provide the counterpart device 2000 with the extracted credit
card in-
formation and user information. The credit card information may include, for
example,
information about a credit card number and a credit card expiration date, and
authen-
tication information about a credit card. The user information may include,
for
example, information about a user identification value and the date of birth
of a user.
[169] The settlement information providing unit 1600 may provide the
settlement in-
formation to the counterpart device 2000 when the touch input on a credit card
image
continues or is maintained over a predetermined time interval. In so doing, if
a distance
between the device 1000 and the counterpart device 2000 falls within a
predetermined
range, the settlement information providing unit 1600 may provide the
settlement in-
formation to the counterpart device 2000, but the present exemplary embodiment
is not
limited thereto.
[170] The settlement information providing unit 1600 may provide the
settlement in-
formation to the counterpart device 2000 when fingerprint information obtained
based
on the touch input on a credit card image is determined to be valid with
respect to the
stored information which relates to the user of the credit card.
[171] The settlement information providing unit 1600 may provide the
fingerprint in-
formation about the recognized fingerprint to the counterpart device 2000. In
this case,
the counterpart device 2000 provides the received fingerprint information to
the
settlement server 3000, and thus, a settlement may be performed.
[172] The memory 1700 may store various pieces of information which are
useful and/or
required in order for the device 1000 to display a credit card image on the
lock screen
and to provide information to the counterpart device 2000 for performing a
credit card
settlement.
[173] The transceiving unit 1800 may transceive information which is usable
for
performing a credit card settlement via the counterpart device 2000 and a
settlement
server 3000. In particular, the transceiving unit 1800 transceives with the
counterpart
device 2000 and the settlement server 3000 various pieces of information which
are
useful and/or required in order for the device 1000 to display a credit card
image on the
lock screen of the device 1000.
[174] The control unit 1900 may control an overall operation of the device
1000 so that the
device 1000 displays a credit card image on the lock screen and provides the
in-
formation about a credit card settlement to the counterpart device 2000. The
control
unit 1900 may control the display unit 1100, the credit card image arrangement
unit
1200, the user input receiving unit 1300, the fingerprint recognition unit
1400, the

[183] An operation of providing settlement information by using a credit
card image on a
lock screen according to an exemplary embodiment is described below.
[184] At least one of the mobile communication module 1061, the WiFi module
1062, the
Bluetooth module 1063, and the NFC module may receive information about a
credit

2000. For
example, as the device 1000 approaches the counterpart device 2000, the device
1000
may receive credit card information via the NFC module.
[185] The application module 1073 may determine a credit card image to be
displayed on
the lock screen by using the credit card information, and may determine how
the de-
termined credit card image is arranged and displayed. The UI module 1072 may
display a credit card image on the lock screen based on the determination of
the ap-
plication module 1073.
[186] The touch screen module 1071 may receive a touch input with respect
to a credit card
image from a user, and may recognize a fingerprint of a user based on the
received
touch input.
[187] The application module 1073 may unlock the device 1000 when the
recognized fin-
gerprint information is similar to fingerprint information which is stored in
the memory
1060. The application module 1073 may provide the credit card information
about the
credit card which is selected based on the received touch input and the
recognized fin-
gerprint information to the counterpart device 2000. In this case, the
application
module 1073 may provide the credit card information and the fingerprint
information
to the counterpart device via at least one of the mobile communication module
1061,
the WiFi module 1062, the Bluetooth module 1063, and the NFC module.
[188] As described above, such connection information is transferred to a
push server via a
cellular network and is finally pushed to a second mobile terminal that is
selected by a
user from a contact list. When a mobile terminal that acquires the connection
in-
formation makes a request for connection via a wireless local area network
(LAN), the
application module 1073 in interaction with the WiFi module 1062 forms a
wireless
LAN link with a counterpart mobile terminal.
[189] Next, a mode by which the device 1000 operates as a second mobile
terminal is
described below. When a push message which includes the connection information
is
received via the mobile communication unit 1001, the application module 1073
displays, on the lock screen, a selection menu requesting whether to set a
wireless
LAN link with the first mobile terminal. If a user touches a button for
approving
connection via the touch screen 1018, the application module 1073, in
interaction with
the WiFi module 1062, forms a wireless LAN link with the first mobile
terminal.
[190] An exemplary embodiment may be embodied in form of a recording medium
which
includes computer executable command languages such as a program module which
