METHOD FOR CONVEYING A LOCATION OF A PRODUCT WITHIN A DEFINED
(RETAIL) ENVIRONMENT
BACKGROUND OF THE INVENTION
Technical Field
The present invention relates in general to the purchase of discounted
products, and in
particular to a method and system for efficiently utilizing coupons for the
purchase of products. Still
more particularly, the present invention relates an electronic, computerized
coupon redeeming
method and system for utilization during purchasing of products.
Description of the Related Art
Redeemable coupons, such as merchandise coupons and rebate coupons, are
frequently
utilized to entice consumers to purchase particular products and/or brands of
products. Advertisers
constantly issue or publish printed coupons which can be taken to a redemption
center, such as a
retail store, and redeemed for some value or as a discount toward the purchase
of some item. While
this method has proven to be effective, there are many disadvantages to the
process for the user, for
the redemption center or retail store, as well as for the advertisers
themselves.
The problems associated with clipping coupons by a user are manifold. First, a
user must
purchase or otherwise obtain a publication and search through the publication
for coupons which
would be meaningful or useful to the user. The user must then cut out the
coupons, being of various
physical sizes, leaving a pile of scrap paper and holes in the pages of the
publication. Some
advertisers use handouts or flyers which, although making the searching job
easier, leaves the
problem of having to cut out the coupons. This tends to be an annoying task
which results in a waste
of valuable time. Being of different sizes and pertaining to different types
of products, the user must
separate the coupons into product categories and band the coupons together as
best as he or she can.
The user then has to store these bits of paper in some location. When finally
on his way to shop, the
user stuffs these sorted coupons into a pocket or purse. Upon arrival at a
particular retail outlet at
AUS9-1999-0526
CA 02316123 2000-08-17
which at least some of the coupons are redeemable, the user fumbles through
the groups of coupons
and attempts to find the products in the store. In the event that the user is
not familiar with the layout
of the store, this again constitutes a gross misuse of valuable time.
Furthermore, since each store lays
out their products differently, and carries different products and brands
ofproducts, the user may find
it necessary to search out the desirable item in a number of stores. Finally,
upon gathering the
product into the pushcart or basket, the user is faced with selecting the
coupons for the products and
presenting them to the store clerk or cashier.
This then leads to the next problem associated with coupon redemption, in that
the store clerk
must sort through the coupons, ensuring that they relate to the products being
purchased and that the
expiration dates are appropriate, and then enter the discount information in
the computer (usually by
a bar code scanner). This part of the redemption process takes valuable time
away from the checkout
clerk and irritates other people waiting in the checkout line. After the
customer leaves, the retail
store is still not relieved from further expenditure of valuable employee
time, since the accumulated
coupons in the retail store must now be sorted by manufacturer, tallied on a
score sheet or in a
computer or submitted to brokerage house, and sent off to the manufacturer for
retail store
reimbursement.
Several previous patents have attempted to create more efficient ways of
handling coupons.
Powell (Pat. No. 5,806,044) discloses a personal computer system which
receives coupon
information and translates them into a binary format before encoding them unto
a portable customer
card used at checkout in place of the paper coupons. Holman (Pat. No. 5,287,
181 ) discloses an
electronic coupon generating system which uses a television transmission
signal along with a
decoder and recorder to encode the coupon information on a magnetically
striped card (such as an
ID card) called the Q card which can be swiped though the card reader at the
cash register.
One of the fastest growing areas of communications is the Internet or World
Wide Web
(VVWW). The Internet is widely utilized in selling products through a fast
growing E-commerce
business. The World Wide Web (Web) is a graphic, interactive interface for the
Internet (the term
Internet is utilized interchangeably with Web throughout this specification).
There are different
computer program applications (web browser clients, referred hereinafter as
web browser) on a data
processing system connected to the web that are utilized to access servers
connected to the Web.
AUS9-1999-0526 2
CA 02316123 2000-08-17
Today, most networks are connected to the Internet and have a home web page
which can be
opened/accessed by a web browser. A web page is a graphic display which is
usually linked together
and may be downloaded to a data processing system utilizing a web browser.
Each web page has
a unique address, or Universal Resource Locator (URL) within the Web that is
accessible by utilizing
Transfer Control Protocol/Internet Protocol (TCP/IP) transactions via
telecommunication networks
and a modem. The address allows a web browser to connect to and communicate
with a HyperText
Transfer Protocol (HTTP) server over the Web.
The fast growing web activity has led many companies to advertise products on
the Internet.
However, most companies which are engage in the retail business still spend
lots of their resources
on the paper coupon system described above. There is presently no way to
effectively provide
coupons via the web which a user can select without having to print the coupon
off the site and go
through the time consuming process described above.
The present invention recognizes that it would therefore be advantageous to
have a method
and system for utilizing the web to more efficiently distribute redeemable
coupons. It would also
be advantageous if such a method and system allowed a user to select and store
desired coupons
electronically via the web. It would be further advantageous to have a method
and system which
could help a customer to locate products for which the customer has
electronically redeemable
coupons.
SUMMARY OF THE INVENTION
It is therefore one obj ect of the present invention to provide an improved
method and system
for purchasing discounted products.
It is another object of the present invention to provide a method and system
for efficiently
utilizing coupons for purchasing products.
It is yet another object of the present invention to provide an electronic,
computerized coupon
redeeming method and system for utilization during purchasing of products.
The foregoing objects are achieved as is now described. A method is disclosed
for creating
an electronic database of shopping products with electronically redeemable
discounted information
or coupons. Customers are each provided with a customer account linked to a
customer
AUS9-1999-0526 3
CA 02316123 2000-08-17
identification (ID) which are also stored electronically. Desired products
and/or coupons are selected
by a customer from the database and stored in the customer's account prior to
shopping for the
product. The customer account is connected with and accessible from the retail
store by the customer
ID. Participating retail stores provide a mechanism for easily locating the
discounted/couponed
products when the customer is shopping. Finally, the check-out system of the
retail store allows the
stored electronic coupons to be redeemed by the customer using his customer
ID.
In one embodiment of the invention, the universal products code (UPC) or other
identifying
information of the products is proj ected into an area of a controlled
environment in which a customer
travels. The transmitter utilized is a recessed, modified infra-red (IR) light
emitting diode (LED).
The modified IR light is utilized to indicate a location of products in the
area of the projection. In
this embodiment, the customer is provided with a portable mechanism which
receives and deciphers
the modified IR light and signals to him that the desired product is located
in the area as the customer
approaches.
In another embodiment, the customer's personal ID is utilized to activate a
shopping tool such
as a IR receiver on a shopping cart. The personal ID is stored on an ID card
which is swiped through
a card reader connected to the IR receiver. The IR receiver is able to
recognize the modified IR
signals containing UPC and other information and identify a location of a
desired product.
In still another embodiment, the customer has a portable reader such as a
palmtop computer
which recognizes the transmitted, modified IR signal having digitized product
information and
initiates a check of its memory for a match with the desired products when it
encounters the modified
IR signal. The portable reader then alerts the customer of the location of the
product.
In a final embodiment, the controlled environment is provided with a customer
accessible
product locator. The product locator may be a data processing system connected
to the database of
products and corresponding product location. The customer enters his unique ID
and is provided
with a visual output of the desired products and their specific locations.
The above as well as additional objects, features, and advantages of the
present invention will
become apparent in the following detailed written description.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENT
With reference now to the figures, and in particular with reference to Figure
lA, there is
depicted the basic structure of a data processing system 20 utilized in the
preferred embodiment of
the invention. Data processing system 20 has at least one central processing
unit (CPU) or processor
housed in casing 22. CPU is connected to several peripheral devices, including
input/output devices
such as a display monitor 96, keyboard 82, graphical pointing device 84, and
printer 94 for user
interface. Also housed in casing 22 are a permanent memory device (such as a
hard disk) for storing
the data processing system's operating system and user programs/applications,
and a temporary
AUS9-1999-0526 5
CA 02316123 2000-08-17
memory device (such as random access memory or RAM) that is utilized by CPU to
implement
program instructions. CPU communicates with the peripheral devices by various
means, including
a bus or a direct channel (more than one bus may be provided utilizing a bus
bridge).
Data processing system 20 may have many additional components which are not
shown such
as serial, parallel, and USB ports for connection to, e.g., modems 92 or CD
ROM 78. In the
preferred embodiment of the invention, communication to the data processing
system 20 is made
possible via a modem 92 connected to a land line or wireless cellular
telephone system which is in
turn connected to a local network provider such as an Internet Service
Provider (ISP). Additionally,
data processing system 20 may be connected to a network via an
ethernet/network card or adapter
90. Communicated data arrives at the modem or network card and is processed to
be received by
the data processing system's CPU or other software application.
Those skilled in the art will further appreciate that there are other
components that might be
utilized in conjunction with those shown in the block diagram of Figure lA;
for example, a display
adapter connected to processor might be utilized to control a video display
monitor 30, and a
memory controller may be utilized as an interface between temporary memory
device and CPU.
Data processing system 20 also includes firmware whose primary purpose is to
seek out and load an
operating system from one of the peripherals (usually permanent memory device)
whenever the data
processing system is first turned on. In the preferred embodiment, data
processing system contains
a relatively fast CPU along with sufficiently large temporary memory device
and space on permanent
memory device, and other required hardware components.
Conventional data processing systems often employ a graphical user interface
(GUI) to
present information to the user. The GUI is created by software that is loaded
on the data processing
system, specifically, the data processing system's operating system acting in
conjunction with
application programs. Two well-known GUIs include OS/2 (a trademark of
International Business
Machines Corp.) and Windows (a trademark of Microsoft Corp.).
Modem 92 can be utilized to connect data processing system 20 to an on-line
information
service or an Internet service provider. Such service providers may offer
software that can be
downloaded into data processing system 20 via modem 92. Modem 92 may also
provide a
connection to other sources of software, such as a server, an electronic
bulletin boaxd (BBS), or the
AUS9-1999-0526 6
CA 02316123 2000-08-17
Internet (including the World Wide Web).
The implementation of the present invention occurs on a number of data
processing systems
as described above. It is understood however, that other types of data
processing systems are
possible, which may have some or more of the basic components described above.
In one
embodiment, portable data processing systems are utilized during the locating
of products as will be
described below. These portable systems may include palmtops and laptops.
This invention has three major components: First, it allows users/customers to
establish a
discount for a product, set of products, or a brand of products as a result of
some computer activity.
Second, it assists customers in locating discounted products when shopping.
Third, it permits
electronic redemption of coupons for products purchased. For clarity, the
disclosure is divided up
into these major components which are presented as: A. Web-based, computerized
coupon network
database; B. Product locating system within a retail environment; and C.
Electronic redemption of
products and discounts.
A. Web based Computerized Coupon Network Database.
In a preferred embodiment of the web based coupon system, a database of
products and
coupons are made available on-line via the Internet at the web site of a
particular retail store, (for
example, HEB, Albertsons, Randalls), the manufacturer's web site, or the
product/brand web page.
Typically, retail stores operate as a chain of stores and offer the same
coupons regionally or
nationally. They are also often interconnected via a computer network. The
computer network
within which the preferred embodiment may be implemented is illustrated in
Figure 1B.
Figure 1B is comprised of a plurality of network servers 4, 6, and 8 and
individual client
computers 12. One main network server 8 operates as the memory storage
location for the database
of products, customer ID and coupon/discount information utilized within the
invention. Main
network server 8 may exist at the product manufacturing site (i.e., the
brand's merchandising
department) where coupon information is entered into the database for use
within the invention.
Alternatively, main network server 8 may exist at one of the server locations
such as a store or retail
outlet. Those skilled in the art are familiar with networked outlet chains
such as HEB and Target,
etc. which have interlinked network computers. Local servers 4 and 6 are
located within the store
AUS9-1999-0526 7
CA 02316123 2000-08-17
areas 5 and 7, respectively, in which the customers shop. Store areas contain
client computers 12
which are preferably computerized cash registers equipped with a UPC scanner
and customer ID
recognition unit (reader) (which may be the same as the scanner) for accessing
customer's
discount/coupon information from database on main network server 8. Also
depicted in Figure lA
is a locator unit 13 which is interlinked with main network server 8. Locator
unit 13 is utilized by
a customer for locating within the retail environment as will be discussed
later.
As illustrated, main network server 8 is connected to the Internet 9 which
displays to a web
browser application the web page of the corporation (store chain or brand
manufacturer) stored on
main network server 8. A user of a web browser application can thus access the
database of products
utilizing his customer ID as described above. Web browser application may
exist on a desktop
computer as depicted in Figure lA; however, in one preferred embodiment, web
browser
applications exist on a portable handheld (palmtop) computer such as the Palm
Pilot (manufactured
by 3 Com) which has Internet access capability. The portability of this system
is important to the
description of one of the preferred embodiments of the invention discussed
later.
In a non-web based application of the invention, the computer network may be a
local area
network (LAN). The LAN is then equipped with a login phone number and
affiliated login ID to
allow for remote login to the system and database.
In one embodiment of the invention, the customer computer has external
connection points
such as an application programming interface (API) which permit a small
handheld scanner to be
plugged into the system. This small handheld UPC/coupon code scanner may then
be used to scan
the UPC or other coupon information from a paper coupon as found in the Sunday
newspaper or
store coupon circular. The coupon information is then stored on the local
system (if a portable
handheld system) or stored in the customer account on the main network server
8 or local network
server 4 or 6. Thus, the coupon is electronically tied to the customer ID
number and utilized as
described below. Alternatively, the customer may type in the coupon codes,
eliminating the need
to purchase a special scanner.
Main network server 8 may store customer information at local servers 4, 6
based on the
geographical information entered by the customer. This relieves the mass
storage requirement on
main network server 8.
AUS9-1999-0526 8
CA 02316123 2000-08-17
In a preferred embodiment, a user enters the web site via his home-based
system and enters
his customer ID. The customer ID is an identifying set of alphanumeric
characters which specifically
identifies a user. The ID may be obtained on-line or in-store or by mail
request, etc. In one
embodiment, the ID is issued via a swipe card which is mailed to the customer
or given to the
customer in the retail environment. The database is a storage location
(memory) which stores
product information including coupons information, etc. In one embodiment, the
database also stores
all customer IDs and corresponding customer account information. Once the user
accesses the web
site, he may select particular products and request the coupon discount
(either by clicking on the
visually displayed coupon or entering coupon information from the paper coupon
obtained from the
store or newspaper, etc. Alternatively, the web site is interactive and
immediately provides
information on all applicable discounts or coupons available when the customer
enters the product
identifying information (name, brand, etc.). Selections made by a customer are
stored in the
customer's account for the time period until the expiration of the coupon
discount. Limits may be
enforced to prevent a user from overloading his account or stockpiling coupons
in his account.
In a preferred embodiment, the product information stored in the customer
account may be
stored in a temporary file or permanent file. Products which are desired only
once are stored in the
temporary file. Other products which a customer purchases on a repeat basis
are placed in a
permanent file. After selection of a product or discount, the user is prompted
to select whether he
wishes the product to be stored permanently. The user may then choose the
product to be a regular
item to be purchased more than once. The functionality and use of this method
of storage will
become more obvious below in section C of the disclosure.
In another embodiment, utilizing a manufacturer-based system (i.e., not retail
store system),
the web activity includes visiting the product/brand web pages, filling in
survey information, or
supplying ISP information so that the brand can send further advertisements to
the user to be inserted
at select times during web activity. In exchange, the user is given an
Internet based discount for the
products or brand. Additionally, the customer may be requested to fill out a
survey or questionnaire,
which when answered results in the issuance of a virtual coupon, which can be
placed in the
customer account by filling in the customer ID.
AUS9-1999-0526 9
CA 02316123 2000-08-17
In a preferred embodiment, an ID card is required to identify the user in the
procedure. A
smart card would be most ideal, but in the absence of smart cards, other
alternatives are workable.
For example, a customer's credit card number can be used (perhaps without the
expiration date) or
a grocery store discount card. When filling in the information at the store or
brand's web site, the
customer could supply his credit card number or grocery store discount card
number as his ID.
Geographic information for the user would also be requested. The set of ID
numbers for a given
geographical location can be cached locally for quicker access during
checkout. Most optimally, ID's
or downloaded ID files which are linked to a particular geographic area and
selected products would
be stored locally in the store's computer, which is in turn connected to all
of the checkout registers.
Two methods of storing the client-based information is disclosed. The first
utilizes the
database of the retail store. However, with the large number of clients for
chain retail stores, this
could prove to be a very expensive enterprise requiring extensive amounts of
memory storage area.
In one embodiment, this could be relieved by having the customer select a
particular geographic
location. Each smaller size location is then outfitted with its own database
of customer accounts
interconnected with other databases to allow for roaming by a customer (i.e.,
shopping outside of his
geographical area).
In one embodiment, a small hand-held/portable data processing system is
utilized. This
system may be a palmtop computer or similar portable mini-computer system with
Internet
capabilities. A user could easily log on to the Internet, get his desired
discount coupons, download
and store them on the palmtop computer prior to heading off to the store.
In the second method of storing user information on a database, a means of
accessing the user
account is also required. In the preferred embodiment, the user is again
provided with an ID card
which contains his alphanumeric ID. The ID card may be an ID card having a
magnetic strip which
could easily be swiped through a card reader (locator unit) connected
electronically to the database
storing the customer account as illustrated in Figure 1B. One method of
establishing access through
said readers is through connecting the database to a network of computers such
as a LAN which has
terminals at the store locations. These terminals could be the cashier
registers equipped with
specialized software for accessing the database. Use of card readers are known
in the art and are
currently utilized in retail establishments. However, the invention extends
the functionality by
AUS9-1999-0526 10
CA 02316123 2000-08-17
linking the customer ID to a stored customer account containing the discounted
products. The card
readers may be located at other locations within the store to enable customers
to locate the required
products. This aspect is discussed within section B below.
B. Product Locating in a System Retail Environment.
Figure 2A depicts a shelf 201 in a retail establishment having products stored
on a series of
shelves 203. Shelf unit 201 may be one side of an aisle 214 or a back wall in
a store. Located at
specific intervals above the aisle 214 of along shelf unit 201 are a number of
recessed Infra-red (IR)
light emitting diodes (LED) 221. IR LEDs 221 emits infra red light modulated
with digital signal,
which conveys the UPC code, price, applicable coupon/discount information and
other data of
products stored on the shelf in that area. Modulating of the LED signal is
handled by a data
processing system which converts known product information to a digital format
which may then
be linked to and emitted along with the IR light. Changes to the database
results in corresponding
changes to the modulated signal. This process is preferably controlled by a
system manager to
ensure accurate broadcasting of product locations.
Figure 2B displays the UPC emitter as a recessed Infra-red (IR) light emitting
diode (LED)
221 in the roof 223. The recessed IR LED 221 produces a cone shaped IR signal
which projects to
the ground below IR LED 221. The IR signal falls on a circular area 213 of
aisle 214 in front of shelf
unit 201. In a preferred embodiment, IR LED 221 is recessed so that the
projected IR signal does
not intersect with the signal of a neighboring IR LED 221. IR LED 221 is
preferably placed in the
light fixtures of the retail store. Although the IR signal area on the ground
is described as a circular
area, it is understood that the signal may be configured to project in a
different shaped area, such as
a rectangular area.
Additional embodiments which use the modified IR signal in a retail
environment involves
placing the IR LED in a drive up area of the retail environment. A customer
with a portable IR
receiver is alerted to the presence and/or location of desired products which
have been pre-
programmed into the portable IR receiver. Depending on the strength of the IR
signal, customers
may be alerted as they drive by on a street which runs through a
circumferential diameter of the
emitting IR LED signal. Although this feature has been described with
reference to its application
AUS9-1999-0526 11
CA 02316123 2000-08-17
in a retail environment, use of the features of a modified IR signal may be
applied to non-retail
environments as well. For example, an IR LED may be placed within a stop light
and transmit
address information. A person with a specialized, portable IR receiver may be
provided the
directions to a particular address which has been pre-programmed. In this
environment, the IR
receiver enables a portable address locator.
Returning to Figure 2A, a customized shopping aid 209 such as a shopping cart
or basket
is utilized by a customer to assist the customer in transporting
items/products selected during
shopping. In one embodiment, customized shopping aid 209 has an IR receiver
211 affixed to it,
which receives IR signal modulated with UPC codes of the products off the
shelves 203 in the
specific broadcast area of the IR signal. IR receiver is a part of a product
locator unit which is
connected to the database. It is also referred to herein as the portable unit
of the product locator unit.
Located either locally on the cart or remotely in another area of the retail
environment is the base unit
of the product locator unit. The base unit is coupled directly or indirectly
to the portable unit
depending on its location. The product locator unit is activated by providing
it with a customer ID
to which preselected/desired product information is linked. The customer
identifies himself to the
IR receiver unit 211 attached to the shopping cart by sliding through his
swipe ID card, which may
be his credit card. The ID is used to access the database and determine which
products the customer
should be notified about.
In one embodiment, the IR receiver 211 is connected via a wireless connection
to the base
unit which is connected to the database holding the customer account so as to
quickly access the
customer coupon information. The IR receiver also has an output mechanism for
identifying to the
customer which product has been matched along with its price discount
information and location.
While passing in circular area 213, the IR receiver 211 picks up the emitted
IR signals. A
comparison of the products identified from the emitted IR signals is made to
the list of customer's
desired products at the base unit. The comparison may also search for products
for which the
customer has selected a coupon discount (or the customers' grocery list). When
a desired product
information is found within the emitted IR signal, the user of the shopping
aid is alerted to the
presence of the product. The IR receiver 211 alerts the customer of the
presence either audibly (such
as via a beep) or visually (on a display monitor of by print-out). IR receiver
211 may be a
AUS9-1999-0526 12
CA 02316123 2000-08-17
combination device which incorporates a scanner functionality with which
information about a
product (e.g. price) is read while shopping.
In an alternate embodiment, the customized shopping aids are given specific
tags by which
they may be electronically identified. The customized shopping aids are then
placed in an
electronically monitored area. The monitored area has a ID card reader
connected to the retail store's
computers. If a customer wishes to use a cart, he must first swipe his ID card
through the reader or
enter his ID information into a punch pad connected to the reader. This links
the particular cart (via
its tag) to the particular customer ID. In this embodiment, the product
location information is made
available via a locator unit at each aisle or at the entrance to the retail
environment. The customer
again enters his customer ID and is provided with a print-out or visual
display of the desired
products, their location in the retail store and other information. This
allows the customer to quickly
locate the desired products. When the customer brings the shopping aid to the
cash register, the tag
is read automatically by a reader at the cash register. The computer is able
to identify the customer
by the customer ID linked to the tag and apply the applicable
coupons/discounts to products
purchased.
In a preferred embodiment, a palmtop computer is utilized in place of the
product locator
unit. The palmtop computer is utilized to store the list of customers items
(shopping list) and
electronic coupon/discounts. This element utilizes the functionality of the
palmtop computer which
operates as a data processor having memory for storing a customer's product
information. During
stage A of the invention, the palmtop computer is hooked up to the Internet
and the electronic
coupons are downloaded as previously described. Alternatively, the coupons may
be manually
entered or scanned in using input devices of the palmtop. Additionally, other
product information,
such as a customer's grocery list, may be stored on the palmtop computer. The
palmtop computer
utilizes its IR port to detect the modulated IR signal. The palmtop computer
is programmed to
compare the information received from the modulated IR signal against the list
of pre-stored
customer product information. If the comparison results in a match of a
product, then the product
and applicable price and discount is displayed on the palmtop computers
display screen. The
customer is therefore alerted to the presence of the particular product on a
nearby shelf or product
area and provided all relevant pricing and discount information
simultaneously. Typically, palmtop
AUS9-1999-0526 13
CA 02316123 2000-08-17
computers are customer owned devices.
Returning to Figure 2, a more specific example is now provided. For this
example it is
assumed that the customer obtains a coupon for product A which has a 20%
discount. The customer
enters the coupon information on- line via the Internet by accessing the
stores web site with his
customer ID. The product coupon is stored either in the main server database
or in the local server
database based on the geographical information entered by the customer. When
the customer goes
to the store, he collects a basket with an IR receiver (or tag) attached. The
customer slides his smart
card through a slide area on the IR receiver or manually enters the ID
information on a punch pad
of the IR receiver. This automatically triggers a wireless connection to the
database and the
customer's desired product and coupon information is retrieved. The IR emitter
207 emits the
modified IR signal with the UPC codes for all the products in its area (A, B,
C, and D). When the
customer pushes the basket in the area 213 of the emitted beam, the IR
receiver picks up the UPC
codes of the products and forwards it to the database for a comparison. The
database checking
algorithm checks all four products against the customer product and coupon
information and returns
with a match for product A with a 20% coupon discount. This information is
relayed to the customer
via an audible signal or visual display on the IR receiver. When the customer
goes to the check out
counter (cashiers) he swipes his card in the card reader or enters his
customer ID on a punch pad.
The cashier machine has an internal computer linked to the database which
automatically gives the
customer a 20% discount on product A. The print out of the receipt displays
this discount and a sum
total of the savings based on the coupon redemption.
In another embodiment of the invention, each aisle is provided with a monitor
unit having
a swipe area or punch pad. The customer goes to the monitor unit and enters
his customer ID via one
of the two input methods. This triggers the search for matching products among
the products on
either side of the aisle. When a match is found, a printout or visual display
of the desires products
and applicable discounts are presented to the customer on the monitor along
with the price, location
in the aisle, discount, etc. In this embodiment, an electronic record of the
location of all the products
on the aisles must also be provided, necessitating access to a database or
memory storage location.
Figures 3, 4 and 5 illustrate the various processes utilized in the
implementation of the
AUS9-1999-0526 14
CA 02316123 2000-08-17
invention. Figure 3 depicts the process of entering the coupon information.
The process begins (step
301) when the user logs unto the web page of the store and enters his customer
ID to open his
customer account (step 303). The user then enters the coupon information (step
305). This step may
be completed utilizing a punch/keypad or a scanner or another input device
such as a microphone.
Alternatively, the coupon information may be made available on-line requiring
the customer to click
on the relevant product and coupon. The coupon information is then stored in
the customer account
(step 307) on the server database which is linked to local store database/
computer system (step 309).
Then the process ends (step 311).
Figure 4 depicts the process of locating the discounted products in the store.
The process
begins (step 401) when the customer enters his customer ID in the IR receiver
(step 403). The
customer account is accessed (step 405). An IR emitter transmits the UPC of
the products on the
shelves in the aisle. When the customer enters the area of the signal, the UPC
is read and compared
against the customer product and discount information for a match (step 409).
If there is a match,
then the customer receives a signal of the location of the item and other
relevant information (step
411). Then the process ends (step 413).
C. Electronic Redemption of Products and Discounts
When the user checks out at the store, the cash register checks whether the
user is entitled to
a discount for the products as they are scanned in, and if so the reduced
price is given, and at the end
of the receipt, a statement is made that a certain dollar amount was saved by
buying brand XXX
products.
Figure 5 depicts the process of checking out with discounted items. The
process begins (step
501) when the customer ID is read accessing the customer account (step 503).
The database runs an
algorithm which determines if the item being scanned has an applicable coupon
discount (step 505).
If it is not discounted, then the process ends (step 513). If, however, the
product has applicable
coupon discount, then the discount is applied to the item (step 507)
electronically. A running total
of the amount saved is kept by the cashier computer (step 509). The total
savings is outputted to the
customer (step 511), then the process ends (step 513).

Various modifications of the check-out process are implemented depending on
the product
location method utilized. In the more general application in which no location
information is
required, a customer simply enters his customer ID during check-out of
products. The applicable
discount information is automatically applied from the database to his
purchase.
In the embodiment utilizing a portable customer owned locator (i.e., the
palmtop computer),
the locator may be equipped with a signal transmitter which sends stored
discount information to a
cash register which is capable of receiving and deciphering the signals. The
discounts are then
automatically applied.
The implementation utilizing the tag or IR receiver on the shopping aid also
operates
similarly to the general application except that the customer ID is read off
of the tag or the IR
receiver by a reader on the cash register. The database if then accessed for
the applicable discount
information.
In the preferred embodiment, the database or portable device deletes the
product and
coupon/discount information from the database of customer selected products
once it identifies a
purchase of the product. However, products which are stored in a permanent
file are not deleted.
Thus, the list of products are automatically deleted from the customer ID at
purchase only if they
were stored in the temporary file.
This invention has several noticeable benefits. Utilizing the invention, a
customer does not
have to carry around coupons to remind himself which products are on sale.
Also, he doesn't have
to carry a scanner to see if a particular product qualifies for a discount and
to find out what the price
is when it is not marked. This allows a store to support a more dynamic and
adaptive pricing
structure.
Additional applications are possible with this invention. The brand
manufacturer can now
know which users actually bought their products instead of the traditional
anonymous purchase with
a coupon. Quantity limits can be electronically enforced. Additional discounts
can be given when
a given user purchases larger quantities. Stores may also offer product
scanners that users can use
while walking through the store. User are then alerted about items to which
they are entitled to
receive a discount.

The invention eliminates the need for paper handling of coupons. The coupon
originator gets
better information about customer response to the coupons and can better
enforce limits to
customers. Also, it allows for easier checking at the check-out counter and
faster clearing of coupons
since everything is completed electronically. The teller no longer has to scan
each coupon
individually.
While the invention has been particularly shown and described with reference
to a preferred
embodiment, it will be understood by those skilled in the art that various
changes in form and detail
may be made therein without departing from the spirit and scope of the
invention.
