APPARATUS AND METHOD FOR hSSUING DOCUMENTS OF VALUE
FIELD OF THE', INVENTION
The present invention relates to dispensers for documents of value and, more
particularly,
to an automated apparatus and method for issuing negotiable instruments.
BACKGROUND OF THE INVENTION
Negotiable instrument dispensers, such as money order dispensing machines, are
well
known in the art. Money order dispensing machines ("MODs"), which are also
referred to by
various names such as "automatic money order di spensers" or "AMODs," or
"RMODs" or
"Deltas," allow for the issuance and sale of mone;;~ orders at a wide variety
of convenient
locations. For example, MODs commonly are placed at convenience stores, check
cashing
agencies, grocery stores, financial institutions, and other retail and service
outlets. The "issuer"
of the money orders generally authorizes an "agent" (c:.g., the grocery store)
to operate the MOD
at each location.
When a MOD is installed at a particular site, and periodically thereafter,
blank money
order forms (which are negotiable documents and ;ire sometimes referred to as
"negotiable
stock") are loaded into a compartment within the MC1D. As customers purchase
money orders,
the operator enters appropriate information (e.g., amount), and the MOD prints
the information
on the forms and dispenses the completed money orders. The forms are typically
numbered
sequentially. When the MOD is loaded, the operator loading the forms enters
the serial numbers
of the first forms. As money orders are purchased, the MOD increments a
counter to keep track
of which forms have been printed on. The MODs also provide reports of MOD
activity, either
electronically or in printed form.
Issuers generally must closely manage their MODs. MODs typically include a
number of
mechanical components and, therefore, commonly malfunction. Additionally, each
MOD
1
CA 02494885 1997-10-02
contains negotiable documents that may be used to -mpose financial liabilities
on the issuer. To
facilitate management of a widespread system of MODs, the MODs should have
certain features.
MODs should be user-friendly. The individuals operating the MODs (e.g. clerks
at a
convenience store) typically have little or no techni~~al training. Moreover,
it may be important
for a large number of employees of a particular agent, such as a retail store,
to operate a
particular MOD. It is not practical for an issuer to yrovide training to each
individual who will
operate an MOD. Unfortunately, many conventional MODs are not sufficiently
easy to use. For
example, it is often difficult to properly reload the YIODs with negotiable
stock. Conventional
MODs are also often bulky and difficult to install at agent sites.
MODs should also incorporate security features to prevent unauthorized usage
and
minimize the risk that counterfeit money orders will be created. Most
conventional MODs
incorporate relatively primitive and limited securit3~ measures. For example,
the compartment
containing the blank negotiable documents genera113~ is locked, and may be
opened only with a
physical key. This security measure can prevent some types of unauthorized
access, but permits
free access to anyone who has obtained the key. Ix also does not provide any
record of who
accessed the negotiable documents and what activity took place during such
access.
Consequently, it is often difficult to determine in a timely manner whether
documents have been
removed and whether misuse may have occurred.
MODs should also provide a mechanism with which the issuer can monitor usage
of the
MOD. Most conventional MODs do not provide a mechanism for easy monitoring and
rely on
information supplied to the issuer or the device itself by the user. For
example, conventional
MODs generally do not verify the sequence of the items during the sales
process, instead relying
on the initial number entered by the operator as described above. In the event
the documents
become out of sequence, the MOD records the expected serial number without
verification of the
appropriate document on which it is printing.
Some MODs employ a primitive sequence ~rerification technique in which every
third
document contains an identical, detectable mark (i.e., a sequencing mark).
When the MOD
2
CA 02494885 1997-10-02
detects a sequencing mark, it determines whether tree document counter number
is divisible by
three and, if so, assumes that the documents are in sequence. This technique
is inadequate in that
it does not detect all types of sequence errors. For example, if three
consecutive documents were
removed from the sequence, the system would not detect the problem.
Additionally, prior art devices may require the issuer to physically inspect
the MOD to
obtain many types of information or use techniques such as the sequencing
mark, which makes
broad assumptions. Conventional MODs also generally require that
reconciliation reports be
printed on a blank money order form or require the purchase of an additional
printer. These
reports are either difficult to read, poorly formatted. and require the use of
a blank negotiable
document, or require an additional hardware purchase.
Accordingly, there is a need for an improvea. system for issuing negotiable
instruments
that provides advantages over prior systems.
SUMMARY OF THE INVENTION
The present invention provides an improved system for issuing documents of
value.
Embodiments of the present invention can provide more convenient, secure and
efficient means
for issuing negotiable instruments or other documents of value, and for
loading, selling and
reporting activity relating to negotiable instrument dis pensers.
The present invention allows for embodiments having many advantages, including
the
following:
(i) They allow for an audit trail that accounts for every document placed in
the printer.
(ii) They allow for easy loading of the machine and facilitate the
determination of what
was loaded.
(iii) They are user friendly.
3
CA 02494885 2006-07-26

DESCRIPTION OF PREFI~RRED EMBODIMENTS
In preferred embodiments of the present invention, an operator uses a control
terminal to
operate a document dispenser (preferably, a negotiable instrument dispenser)
which provides a
more convenient, secure, user-friendly, and efficient means for loading,
selling and reporting
information relating to negotiable documents. The control terminal is
connected to a printer/vault
housing negotiable stock, signalling to print a mone~~ order and to unlock the
vault as necessary.
Blank money order forms are packaged in pre-defined bundles with bar code
serial numbers
(MICR, OCR or other encoding techniques may be used), and are stored in the
vault unit of the
printer. The control terminal keeps track of which forms have been printed on
and other usage
information. The activity of the negotiable instrument dispenser is
automatically recorded by the
control terminal in an electronic "journal" (i.e., in mf;mory) and
periodically reported to a central
computer.
An exemplary automatic money order dispenser ("MOD") 10 for use with the
present
invention is shown in FIG. 1. MOD 10 consists of two separate parts: a control
terminal 12 and
printer/vault 14. Installation at an agent/user site simply involves
connecting these two parts
together, and then connecting them to a telephone lir,.e to permit data
transfer, and to an electrical
outlet for power.
Control terminal 12 has three main functions: (1) to communicate with the
issuer's central
computer (i.e., the host system); (2) to control printer/vault 14 in
accordance with pre-defined
rules and user instructions; and (3) to control all other system activity.
From the standpoint of a
user, it consists of a keypad 16, a display 18, and ;gin optional telephone
handset 20. MOD 10
uses ordinary phone lines to transmit activity to the central computer for
quick and efficient
5
CA 02494885 1997-10-02
record keeping. Control terminal 12 also records in its memory a "journal" or
activity log, which
keeps track of its usage information as described furt;:~er herein.
Control terminal 12 keeps track of all transactions until it automatically
"uploads" that
information to the host computer at the issuer's central control facility at
the end of each business
day or at various times throughout the day. The transaction information
preferably is stored in an
internal non-volatile memory (which may be implemented by either a volatile
memory with a
battery backup or a conventional non-volatile memory). The control terminal
also includes
conventional programmable processor hardware so that it can be programmed to
perform the
processes described herein.
An operator uses keypad 16 on control terminal 12 to initiate any transactions
with MOD
10. The steps that must be performed for each transaction are relatively
simple. Instructions on
performing all transactions preferably are described in a user guide provided
to the agent.
The operator enters commands by pressing keys on keypad 16. Preferably, keypad
16 has
three types of keys:
(1) Function Keys. These keys are used to initiate the type of transaction
desired (e.g.,
sales, void, report, cancel).
(2) Numeric Keys. "0" through "9" are numeric keys. A user presses these when
he needs
to enter an amount or code.
(3) Alphanumeric Keys. These keys are used in vendor payment transactions.
Keypad 16
can be implemented by those skilled in the art using any conventional keypad
technology,
including for example softkeys.
Display 18 provides users with important information and prompts users through
the
steps of each procedure. Display 18 can be implemented by those skilled in the
art using
alphanumeric display technology.
6
CA 02494885 1997-10-02
Display 18 is usually at the "status screen.'' This is the starting point of
all functions
available on the terminal. If the display screen shows a different message
before a user begins a
transaction, or a user becomes confused midway through a transaction, he or
she simply presses
"CANCEL" to return to this status screen. The status screen displays the
current date and time,
along with the number of documents in the printer a1d the number of
transactions in the current
day's files for various products applications in same terminal (e.g., money
orders, utility
remittance, phone card, payroll and gift certificates).
Printer/vault 14 preferably comprises a printer portion that contains a
conventional MOD
printer and a vault portion locked to the printer portion. The blank money
order forms are stored
in the vault portion of printer/vault 14. Printer/vault 14 is activated by
control terminal 12. Based
on commands input by the operator, money orders are automatically imprinted
with the amount
specified through contxol terminal 12 and dispensed to the operator. Printer
14 preferably
contains a bar code reader, and the blank money ord<;r forms preferably are
coded with bar code
serial numbers. MICR technology may also be used for this purpose in a
conventional manner. It
will be apparent based on the present disclosure that .any conventional OCR
technology will also
suffice.
1. Loading Procedure
In order to permit the system to determine whether a blank document is at the
beginning,
middle or end of a pack or bundle, the blank documents are prepackaged in sets
of a
predetermined size (e.g., 400 documents) and given serial numbers commencing
with a multiple
of the pack size (e.g., 400, 800, 1200, etc.) The remaining documents are in
serial order (e.g.,
400-799 in one packet). The system can therefore e;~sily determine the
location of a particular
document within a pack and how many documents remain in the pack.
Printer/vault 14 of MOD 10 is loaded with negotiable stock at the agent/user
site. During
loading, the terminal requests a security code. The user inputs a security
code using control
terminal 12, and the security code is verified to have, access rights fox the
load function. If the
7
CA 02494885 1997-10-02
current user has rights to the load function, control tf;rminal 12 sends a
signal to the printer/vault
14 to unlock the vault (preferably using a solenoid or conventional electro-
mechanical lock)
from the printer unit, allowing the user to remove the vault. Display 18
prompts the user to
remove the vault. If the user fails to remove the vault within a pre-defined
time, the printer unit
will re-lock the vault. Access to the vault will r.ot be granted without the
re-entry of an
authorized access code.
After the vault is removed from the printer emit, the user can load a pack of
negotiable
documents into the vault and re-attach the vault to thf; printer. After the
vault is re-attached to the
printer unit, control terminal 12 signals the printer to load the first form
and perform a bar-code
read on the pre-printed bar code on the form. The pre-printed bar code
preferably comprises
numeric and/or alpha characters. Upon reading the pre-printed bar code, the
printer returns the
numeric (or alpha, or alphanumeric) value to control terminal 12. Control
terminal 12 determines
whether the returned numeric value is appropriate and responds appropriately.
More explicitly, the steps are as follows. After control terminal 12 signals
the printer to
load a form and read the pre-printed bar code, the printer begins to load a
form. If the leading
edge of a document is not recognized, the printer will respond to control
terminal 12 that no
documents have been recognized. Control terminal 12 displays an error message
that no
documents were detected and requests the user to reload the forms.
When the leading edge of a document is recognized, the printer attempts to
detect an
under bar which indicates the position of the pre-prin~;ed bar code. If the
under bar is not detected
within a predetermined number of steps, the printer returns a message to
control terminal 12
indicating that the under bar was not detected. The terminal displays an error
message that there
was a loading error and requests that the user reload the forms. In this
manner, the terminal can
detect whether the documents were loaded upside-down or backwards. Control
terminal 12
signals the printer to return the form to the vault.
Once the under bar is detected, the printer attempts to read the pre-printed
bar code on the
form. If the bar code is read successfully, the printer returns the
appropriate values to the
8
CA 02494885 1997-10-02
terminal. The terminal calculates the number of items remaining in the pack,
determines whether
this load was of a full or partial pack; and verifies that the value is in the
proper format. The
terminal also verifies that the value passes all appropriate check digit
verifications, displays a
successful load message to the user, signals the printer to return the form to
the vault, and makes
appropriate entries in the journal (e.g., who opened the printer; time;
whether a full pack or
partial pack was loaded).
Whenever a document is read, control termir al 12 compares the current serial
number to
the expected serial number. If the current serial nmnber is different than the
expected serial
number, the terminal determines if the current serial number is in the same
pack as the expected
serial number. If the current serial number is in the same pack as the
expected serial number, the
terminal records a missing serial number or range of serial numbers in its
internal memory to
indicate that items are missing from the pack. If the current serial number is
not in the same pack
as the expected serial number, the terminal records a missing range from the
expected serial
number to the end of the pack. The terminal then determines if there are
missing items from the
pack from the current serial number. If items are missing from the new pack to
the current serial
number, the terminal records a missing range of serial numbers from the
beginning of the new
pack to the current serial number.
The terminal also determines if the current serial number is the beginning of
a pack, or if
it is an item from the middle of a pack or if that serial number is already
recorded in the journal.
If the current item is the beginning of a new pack, the terminal records that
a full pack has been
loaded. If the current item is in the middle of a pack, the terminal records a
partial pack has been
loaded. If the serial number was previously recorde3 in the journal, the
document is voided by
printing "void" on the document. Again, this activity is entered into the
journal.
The procedure for loading documents is described in more detail herein in
connection
with FIGS. 2(a)-2(d).
2. Issuance
9
CA 02494885 1997-10-02
During the issuance of negotiable documents, control terminal 12 signals
printer 14 to
load a form. Printer 14 begins to load a form. If the l~;ading edge of a
document is not recognized
within a predetermined number of steps within the printer, the printer
responds to the terminal
that no documents have been recognized. The terminal displays an error message
that no
documents were detected and requests that the user load new forms or reload
the current set of
forms. The terminal signals the printer to unload the :orm and return it to
the vault.
Once the leading edge is recognized, the printer attempts to detect an under
bar which
indicates the position of the pre-printed bar code. If the under bar is not
detected within a
predetermined number of steps, the printer returns a message indicating to the
terminal that the
under bar was not detected. The terminal displays an error message that the
under bar was not
detected on the form and requests that the user reload the forms. The terminal
signals the printer
to return the form to the vault.
Once the under bar is detected, the printer advances a predetermined number of
steps and
attempts to read the pre-printed bar code on the form. If the bar code is read
successfully, the
printer returns the appropriate value to the terminal. The terminal verifies
that the value is in the
proper format and verifies that the value passes all appropriate check digit
verifications. The
terminal compares the current serial number to the f;xpected serial number. If
the current serial
number is different than the expected serial number, the terminal determines
whether the current
serial number is in the same pack as the expected ser..al number. If the
current serial number is in
the same pack as the expected serial number, the ~:erminal records a missing
range from the
expected serial number to the end of the pack. The tc;rminal then determines
if there are missing
items from the pack from the current serial number. If items are missing from
the new pack to
the current serial number, the terminal records a missing range of serial
numbers from the
beginning of the new pack to the current serial number.
If the bar code is not successfully read within a predetermined number of
retries, the
printer returns an error message to the terminal indic,~ting that the value
could not be ascertained
from the pre-printed bar code. The terminal displays an error message that the
bar code is
unreadable, then signals the printer to print void on the remainder of the
item and records the
CA 02494885 1997-10-02
expected serial number as a void. The terminal then signals the printer to
load the next form and
attempt the sale. This process continues until a readable form is recognized
in the printer or until
a pre-configured number of items has been voided due to unreadability.
When a readable form is recognized, control terminal 12 instructs the printer
to print
designated data on the document and make the ;rppropriate journal entry. The
MOD then
dispenses the documents.
The procedure for issuing negotiable documents is described further herein in
connection
with FIGS. 3(a)-3(d).
3. Other Features
The control terminal records a list of security codes and their associated
rights in a
memory. The control terminal allows a user to define each security profile
with a unique set of
configurable rights, increasing the flexibility of the security of the device.
For example, certain
operators may be allowed to perform all possible functions and others may be
allowed to
perform only a few functions, such as sales and voids.
In the case of a vendor payment, the money order is used to pay a vendor of
the agent.
This option is made available to some agents to permit them to allow employees
to pay vendors
without the need to maintain large amounts of cash on the premises. If an
agent has been granted
the optional vendor payment capability, the operator can, in many systems,
enter any vendor
name using the alphanumeric keypad. In other syste ms, the operator may be
limited to selecting
from a predetermined list of vendors. In such a system, a plurality of vendor
names may be
stored in the memory within the terminal for printing on the payee line of the
negotiable
documents.
Memory within control terminal 12 records ~. list of fees associated with
ranges of dollar
values. The user can configure the terminal to calculate a fee based on the
amount requested or a
11
CA 02494885 1997-10-02
percentage of the face amount. The terminal records four different ranges of
values associated
with a fee.
The reading of a specific pre-printed bar code for each item ensures the
proper
transaction posting of each sale item The missing item detection allows for a
solid, traceable
audit trail.
As described herein, the present invention utilizes software to unlock and
lock the vault
based on a pre-defined set of rules. For example, thc~ vault may only be
unlocked upon entry of
an appropriate security code. The software monitors and relocks the vault if
it has not been
opened for a predetermined period of time. This software lock/unlock feature
also helps to
provide a traceable audit trail with respect to printer access. The flexible,
completely
configurable security parameters allow the user to define which rights are
accessible by
employees.
Software determines any break in sequence cf the documents, registering these
breaks as
missing items. This is printed on all reports, which s~.rves as an early
warning notice for possible
fraud.
The security code which allows access to sensitive areas of the application is
dynamic. It
changes daily based on a predetermined algorithm. 7'he algorithm may be a
function of the date,
and/or a predetermined identification code. This prevents an agent from
learning the code on one
day while troubleshooting and re-using it at a later date.
Procedure for document loading with bar code logic is now described in
connection with
FIG. 2(a), FIG. 2(b), FIG. 2(c) and FIG. 2(d).
Initially, the system is in an idle mode, displaying the "status" or idle
screen as shown in
Step 100. In Step 102, the user enters a code (for example, function "9") to
indicate that he or she
wishes to load documents into the printer/vault. The system then displays
"Enter User Code" in
Step 104 and the user enters a user access code (sing;le character or multi-
character) in Step 106.
12
CA 02494885 1997-10-02
In Step 108, the system determines whether the user has the rights to load
documents (not all
users will have such a right). If the user does not have such rights, the
system will display
"Access Denied" as shown in Step 110 and will return to the idle screen in
Step 112. If, in Step
108, the system determines based on the access code that the user has the
right to load
documents, the document vault is unlocked in Step 114, and the system displays
"Printer
Unlocked, Remove M.O. Vault" in Step 116. The system also makes appropriate
journal entries.
After displaying this message, a configurahle timer is set (preferably five
seconds),
allowing the user to remove the vault, as indicated i n Step 118. In Step 120,
the system senses
whether the vault has been removed during the predetermined time period. If
not, the vault is re-
locked to the printer, the system returns to Step 104, indicating in its
display that the user should
re-enter his or her user's code and try again. If the user removes the vault
as shown in Step 122,
the system displays "Load Money Orders and Repla~~e Vault" in Step 124. In
Step 126, the user
loads documents and reattaches the vault. The system then checks in Steps 128
to determine
whether an idle timer has expired or the user has pressed cancel. If so, the
system returns to an
idle screen. If not, the system determines whether thE: vault has been
replaced and, if not, returns
to Step 124 indicating on its display that the user should load money orders.
If the vault has been
replaced in Step 130, the system moves on through Node 132 (shown for
convenience in both
FIG. 2(a) and FIG. 2(b)) to Step 134.
In Step 134, the document is advanced under the print head and the bar code is
read. If, in
Step 136, the leading edge of the document has not been located, the system
will display "Printer
Error-Unreadable Bar Code" in Step 138, return the 3ocument to the vault in
Step 140 (setting a
vault empty flag), and return to the idle screen in Step 141.
If the leading edge of a document has been detected in Step 136, the system
will
determine in Step 142 whether the bar code underb~~r has been located and, if
not, will display
"Printer Error--Unreadable Bar Code" (or "U-Bar Lndetected") in Step 144,
thereafter moving
on to Steps 140 and 141 as previously describec.. This detects documents that
have been
incorrectly positioned in the printer/vault (i.e., placed upside down or
backwards).
13
CA 02494885 1997-10-02
If the underbar has been located in Step 1 ~~2, the system will determine in
Step 146
whether the bar code was successfully read. If not, the system will determine
whether the bar
code exceeded a configurable and predetermined retry limit in Step 148 and, if
not, will return to
Step 134. If so, the system will display "Printer Ertor--Unreadable Bar Code"
in Step 150 and
move on to Steps 140 and 141 as previously described.
If, in Step 146, the system determines that the: bar code was read
successfully, the system
will check in Step 152 to determine whether the D.C~. number matches a
predetermined number.
(The D.O. number is the first two numbers of the do;,ument serial number.) If
not, the system in
Step 154 will display "Printer Error--D.O. Does Not Match" and move on to
Steps 140 and 141
as previously described. If the D.O. number does match the predetermined
number in Step 152,
the system will check in 156 to determine whether the check digit is correct
and, if not, the
system will display in Step 158 "Printer Error--Chech Digit Incorrect" and
move on to Steps 140
and 141 as previously described.
If the check digit in Step 156 is correct, the system will display "Documents
Successfully
Loaded" in Step 160, make sure that the vault flag i;; not set to empty in
Step 162 and move on
through Node 164 to Step 166.
In Step 166, the system determines whether the serial number of the document
which last
issued as a money order was the last item in the previous pack of documents.
If so, the system
determines in Step 176 whether the new document (i.e., the document just read
after loading) is
the first serial number in a pack. If so the system posts a "Full Pack Load"'
entry into its memory
(also referred to as a journal) in Step 178 and returns to the idle screen in
Step 180. If the current
document is not the first serial number in a pack, the system posts a "Partial
Pack Load" entry
into the journal in Step 182 and moves on through Ncde 184 to Step 186.
If, in Step 166, the system determines that they last issued document was not
the last item
in the previous pack, the system checks its memory in Step 168 to determine
whether there were
any items missing from the previous pack and, if not, moves on to Step 176
previously
described. If there were items missing from the previous pack, the system
checks in Step 170 to
14
CA 02494885 1997-10-02
determine whether there is more than one serial number missing from the
previous pack. If not,
the system posts in Step 172 a single missing item and moves on to Step 176 as
previously
described. If there is more than one serial number missing from the previous
pack, the system
posts, in Step 174, a missing range item showing thc: first and last serial
numbers. After posting
the missing range in Step 174, the system moves on to Step 176 as previously
described. This
missing range information is printed on all reports and can be transmitted to
the host.
In Step 186, the system determines whether there are any serial numbers
missing from
the current pack. If not, the system returns to an idle screen in Step 188. If
so, the system checks
in Step 190 to determine whether there are more than. one serial number
missing from the current
pack. If not, the system posts in Step 192 a single missing item with the
serial number and moves
on to Step 188 as previously described. If there is more than one serial
number missing from the
current pack, the system posts in Step 194 a missing range item showing the
first and last serial
number and moves on to Step 188 as previously described.
The sale or vendor payment with bar code logic is now described in connection
with FIG.
3(a), FIG. 3(b), FIG. 3(c) and FIG. 3(d).
In Step 200, the system displays an idle screen. In Step 202, the user presses
a function
key indicating a "sale" or "vendor payment." In Step 204, the system displays
"Enter User Code"
and, in response, in Step 206, the user enters his or par user code. In Step
208, the system checks
to determine whether the user has rights to perform a sale or vendor
transaction and, if not,
displays "Access Denied" in Step 210. The system subsequently returns to an
idle screen in Step
212.
If, in Step 208, the system determines that the: user does have a right to
conduct a sale or
vendor transaction, the system and user follow previously established
functions to obtain
information necessary to conduct the sale or vendor transaction, these
procedures being
performed in Step 214, after which the system mo~~es through Node 216 to Step
218. In Step
218, a document is advanced to the printer. The system checks in Step 220 to
determine whether
the leading edge has been located. If not, in Step 222, the system unloads the
document from
CA 02494885 1997-10-02
under the print head and sets the vault empty flag, thereafter displaying in
Step 224 "Printer
Error--L. Edge, Please Check and Reload" and subsequently returns to the idle
screen, Step 226.
If the leading edge for the document is located in :itep 220, the system
checks in Step 228 to
determine whether the underbar is located and, if not, unloads the document
from under the print
head in Step 230 and sets the vault empty flag. In Step 232, the system then
displays "Printer
Error--U. Bar, Please Check and Reload", and subsequently moves to Step 226 as
previously
described.
If, in Step 228, an underbar has been located, the system moves through Node
234 to
Step 236.
In Step 236, the document is advanced under the print head and the bar code is
read. If
the system determines in Step 238 that the bar code was not read successfully,
the system checks
in Step 240 to determine whether the bar code exceeded configurable retry
limit. If not, the
system returns to Step 236. If so, the system displays in Step 242
"Unreadable, Voiding Item,"
prints "Void" on the document in Step 244, posts the voided document to a
record in its memory
(i.e., journal) in Step 246 and checks to determine whether a predetermined
maximum number of
unsuccessful reads has occurred in Step 248. If not, t:le system moves through
Node 215 and 216
to Step 218. If so, the system displays in Step 252 "Unreadable Items, Please
Check and Reload"
or "Unreadable Items--Please Call the Help Desk" ;end in Step 254 sets MO
vault empty flag,
thereafter returning to the idle screen in Step 256.
If the bar code was read successfully in Step ?38, the system moves through
Node 251 to
Step 258.
In Step 258, the system determines whether the D.O. number matches the
predetermined
value in the terminal. If not, the system displays in Step 260 "Printer Error--
D.O. Does Not
Match", unloads the document from under the print head and sets the vault
empty flag in Step
262 and returns to the idle screen in Step 264. If th~~ D.O. number does match
the terminals in
Step 258, the system determines in Step 266 whether the digit is correct and,
if not, displays
16
CA 02494885 1997-10-02
"Printer Error--Check Digit Incorrect" in Step 268 and moves on through Step
262 as previously
described.
If the check digit is correct, the system determines in Step 270 whether the
serial number
is the next serial number expected and, if so, posts this document as a sale
into the journal in
Step 276, prints the remaining portion of the document in Step 280, and
returns to the idle screen
in Step 264.
If, in Step 270, the system determines that thf; serial number is not the next
serial number
expected, the system checks to see whether more then one serial number is
missing in Step 272
and, if not, posts a single missing item with the ser-al number into the
journal in Step 274 and
moves on to Step 276 as previously described. If there is more than one serial
number missing in
Step 272, the system posts a missing range of items showing the first and last
serial number into
the journal in Step 278 and moves on to Step 276 as previously described.
The power cycle with bar code logic is now described in connection with FIG.
4.
In Step 300, the system is turned on. In Stc;p 302, the system determines
whether the
printer power was cycled and, if not, returns to an idle screen in Step 304.
If the printer power
was cycled, a document is advanced under the print head in Step 306 and bar
code is read. If the
bar code is read successfully in Step 316, the system checks to determine
whether the D.O.
number matches the terminal's number in Step 318 md, if so, determines whether
the check digit
is correct in Step 322. If the check digit is correct, the system onsets the
vault empty flag in Step
326, removes the document from under the print head (and optionally checks for
missing items)
in Step 314, and returns to the idle screen, making appropriate journal
entries.
If the bar code was not read successfully in Step 316, the system checks in
Step 308 to
determine whether the bar code has exceeded the configurable retry limit and,
if not, returns to
Step 306. If so, the system displays in Step 310 "Printer Error--Unreadable
Bar Code", sets the
vault empty flag in Step 312, unloads the document from under the print head
in Step 314, and
returns to the idle screen in Step 304.
17
CA 02494885 1997-10-02
If, in Step 318, the D.O. number does not match the terminal's, the system
displays in
Step 320 "Printer Error--D.O. Does Not Match" and moves on to Step 312 as
previously
described.
If, in Step 322, the check digit is not correct, the system displays in Step
324 "Printer
Error--Check Digit Incorrect" and moves on to Step 312 as previously
described.
The download notification and call back procedure is now described in
connection with
FIG. 5. In Step 400, the terminal transmits to the hose: system all of the
data stored in its journal.
In Step 402, the host processes sales data on-line and, in Step 404, the host
performs a
match on device LD. to a "Notification List". In Stc~,p 408, the host system
determines whether
the current device LD. is on a "Notification List" anal, if not, sends a
recorded response in Step
410 and disconnects the call. If, in Step 408, the dev.ce LD. is on the
notification list, the system
sends a recorded response in Step 412 with notification and disconnects the
call. In Step 414, the
terminal checks to determine whether the notification was for a scheduled or
immediate callback.
If the notification was for an immediate callback the system moves on to Step
420, which will be
described hereafter. If the notification was for a scheduled callback, the
terminal waits in an idle
loop checking for the current time to equal the scheduled time in Step 416,
and when the current
time equals the scheduled time, moves on in Step 41 f~ to Step 420.
In Step 420, the terminal determines the notification was for initialization,
program load
or printer load. If the notification was for a printer lo;~d, the terminal
calls the host system in Step
422 to pull in a printer firmware enhancement ;end, after the download is
complete, the
disconnect is in Step 428.
If the terminal determines in Step 420 that the notification was for a program
load, the
terminal calls the host system in Step 424 and downloads a terminal software
enhancement.
After the download is complete, the call is disconnec~:ed in Step 428.
18
CA 02494885 1997-10-02
The notification can also be for multiple procedures (i.e., initialization and
download).
The notification may also be dependent on the unique code or version
associated with each
MOD, which is transmitted to the host system during the call.
If the terminal determines in Step 420 thal the notification was for
initialization, the
terminal calls the host system in Step 426 and downloads a terminal
configuration modification,
thereafter disconnecting the call in Step 428.
A previously issued document may also be reinserted to be voided by the user.
The bar
code reader will verify that the appropriate documem: is being voided.
It should be noted that the present inventio n is applicable to issuing any
document of
value, whether or not the document is negotiable.
It should also be noted that, upon user command, a previously issued document
may also
be reinserted into the printer to be voided. The bar :.ode reader will verify
the serial number to
make certain that the correct document is being voided.
The present invention encompasses all subject matter within the scope of the
claims.
Accordingly, the present invention is not limited to tle preferred embodiments
described above.
