Abstract:
A system and method of generating a tender code for a purchase transaction and associating the generated tender code with both a payment and a produced digital receipt for the purchase transaction is described. The tender code may be assigned at several points in the purchase transaction. The digital receipt with the tender code is stored, preferably in a data warehouse. The data warehouse allows easy indexing of the digital receipt data including the tender code. The payment, such as a check, is encoded or affixed with the tender code such that the payment is correlated or linked to the digital receipt and thus the particular purchase transaction to which the payment applied. The tender code may be encrypted and/or contain auxiliary data. The auxiliary data may be device readable to allow a holder to access various information and/or data via an access device such as a document processing device. The present system provides greater verification and/or validation of payment for a purchase and the purchase transaction.

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to purchase transactions and, more particularly, to a system and method for correlating a check tendered in payment for a purchase to the purchase transaction. 
     DESCRIPTION OF THE PRIOR ART 
     A consumer in today&#39;s marketplace has a variety of options with regard to where to purchase goods and/or services as well as how to pay for the purchase. A consumer may purchase goods and/or services from a retail store, on-line (i.e. via the Internet), via the telephone, or via mail order. A purchase of goods and/or services from anywhere via any means constitutes a purchase transaction. In all purchase transactions there is payment for the goods and/or services. Payment may be made in cash, by check, by credit card, by debit card, or any other method. 
     As evidence of the purchase transaction, a receipt is generated and given to the consumer (buyer). Because the purchase transaction is typically entered into a computer controlled device to calculate the sale, compute sales tax, and perform various other functions, it is known to provide an electronic or digital receipt for the purchase of such goods and/or services. The digital receipt is generated and stored by the business and then delivered via electronic mail (e.g. by e-mail via an electronic network) to the customer/purchaser. Electronic mail, using either a public or open network such as the Internet, or a proprietary network, is a simple means of communicating digital information (i.e. the digital receipt) from one location to another location. Digital receipts are easily stored and retrieved. As such, the data contained in digital receipts is easily accessible. Thus, the digital receipt provides a means for retailers, merchandise suppliers, distributors and Internet retailers to provide purchase transaction and other information to the consumer. 
     In U.S. Pat. No. 5,739,512 entitled Digital Delivery of Receipts, issued on Apr. 14, 1998 to Tognazzini, there is disclosed a system that that stores or transmits receipt information digitally for later use. The receipt information may be delivered over a proprietary or an open network such as the Internet to an email address. The e-mail address is embedded into a bank card or other machine readable card that is used for the purchase. 
     Even though the Tognazzini patent discloses a system that can generate and send an electronic receipt to a customer, such delivery of an electronic receipt does not provide further value to either the customer or retailer other than the compilation of data inherent in an electronic receipt, the quick delivery thereof, and the convenience of electronic retention. It does not provide a correlation to a check tendered for payment. 
     A problem exists in the digital receipt domain for payments made by non-cash, non-credit/debit cards, such as by checks. When a consumer makes a payment by check, the funds are not immediately transferred or credited to the seller. As well, it is difficult to trace the check to the particular purchase transaction. With payment by cash, the transfer of funds is immediate. There is no need to “trace” the payment. As well, with payment by debit card, the transfer of funds is immediate. Additionally, there is a transaction number associated with the debit card payment that is assigned by the debit card company (i.e. bank), the seller, or both. Therefore, the payment by debit card is traceable. With payment by credit card, the transfer of funds is likewise immediate and there is a transaction number associated with the purchase transaction that is assigned by the credit card company, seller, or both. Again, the payment by credit card is traceable. 
     However, with payment by check, there is no immediate transfer of funds. As well, the tendered check is not in any manner associated with the purchase transaction. The check must be forwarded to a clearing house, then to the bank for verification and/or validation for payment to the seller. In cases where the seller verifies the check during the purchase transaction, the tendered check is not associated with the purchase transaction. Thus, the consumer and/or seller cannot readily verify and/or validate that a particular check was tendered in payment for the goods and/or services purchased. This is especially a problem in Internet retail or in any sale where a check is tendered after the purchase transaction, particularly in C.O.D. (cash on delivery) situations. An additional challenge is presented by returns and verification processes. In the cases where the check is received after shipment of the goods or performance of the services, it is difficult for the seller to correlate a check payment with the goods sold and/or services rendered. 
     What is therefore needed is a system and/or method for correlating a payment for a purchase to the purchase transaction and/or to purchased items, merchandise, and services. 
     What is therefore further needed is a system and/or method for correlating a check tendered as payment for a purchase to the purchase transaction and/or purchased items, merchandise, and services. 
     SUMMARY OF THE INVENTION 
     The present invention provides a system, method and apparatus for correlating a payment for a purchase to the particular purchase transaction. Such correlation aids in the verification and/or validation of the payment for the purchase, especially in the context of an electronic purchase transaction environment. In on respect, the check is indexed to purchases and/or purchase transactions. 
     In particular, the present invention provides a system, method and apparatus for correlating a payment made by a check for a purchase, to the purchase transaction via a tender code. More particularly, the tender code is associated with the check and a digital receipt generated for the purchase transaction. The tender code may be encrypted and include auxiliary data. The auxiliary data may be embedded in to the tender code or appended thereto. 
     In one form, the present invention is a method of correlating a check to a purchase transaction. This method may be carried out, for example, utilizing a variety of computer controlled devices, one of which is the retail terminal presented herein. The method includes the steps of (a) receiving a check as payment for a purchase transaction; (b) generating a tender code for the purchase transaction; (c) associating the tender code with the check; (d) generating a digital receipt for the purchase transaction; and (e) associating the tender code with the digital receipt. Associating the tender code with the check may include printing the tender code onto the check. 
     In another form, the present invention is a method of correlating a check given in payment for a purchase to the purchase transaction. The method comprises the steps of: (a) receiving a check given in payment for a purchase transaction; (b) generating a digital tender code unique to the purchase transaction; (c) producing a digital receipt of the purchase transaction; (d) appending the digital tender code to the digital receipt; and (e) affixing the digital tender code to the check. The digital tender code may be affixed to the check during a check verification process. 
     In yet another form, the present invention is a computer controlled device for correlating a check to a purchase transaction. The device includes a processing unit, memory and a slip printer in communication with the processing unit. The memory is in communication with the processing unit and contains a plurality of instructions or code.

     DETAILED DESCRIPTION 
     Referring now to FIG. 1, there is depicted a diagram of an overall system, collectively generally designated  100 , that is able implement the various aspects and/or principles of the present invention. It should initially be understood that the system  100  as depicted in FIG. 1 is representative or exemplary of a business having a brick and mortar location (store) and a web site, each of which sells goods and/or services. The system  100  is not intended to be an exact representation of any particular system nor is it intended to imply that only this type of system may implement the various aspects and/or principles of the present invention. The system  100  as shown in FIG. 1 provides a basic model for understanding the various aspects and/or principles of the present invention, the various forms through which the various aspects and/or principles of the present invention may be manifested, and the many ways in which the various aspects and/or principles of the present invention may be carried out. As well, the system  100  illustrates the many ways in which a business may sell goods and/or services and by which a consumer may make a purchase transaction. It should be appreciated that a business may not utilize every channel of trade or subsystem of the overall system  100  as depicted. 
     A purchase transaction transpires whenever a person or entity transfers money (payment) for goods or services. The purchase transaction can be characterized by a plurality of purchase transaction datum (i.e. purchase transaction data). The purchase transaction data is composed of fundamental pieces of datum regarding the purchase transaction such as what was purchased, where it was purchased, who purchased it, how much it cost, how many were purchased, in what manner was payment tendered, when did the transaction take place, etc. This type of data is obtained and/or generated during a purchase transaction by a variety of purchase transaction devices from a simple cash register to automatic electronic transaction terminals. As well, these devices are operable to carry out the present invention. In particular, these devices and/or sub-systems are operable to accept payment for the goods and/or services. 
     A consumer may purchase goods and/or services in a variety of manners as depicted in FIG.  1 . The system  100  includes an Internet subsystem  130  and an in-store subsystem  132 . Each of these subsystems  130  and  132  allow a consumer or buyer to purchase goods and/or services from the retailer or seller. The business accepts payment for the goods and/or services in whatever form (i.e. cash, credit, debit, check, money order, etc.) as is customary for the particular payment. 
     In FIG. 1, a customer  104  may visit a store  102  and purchase goods and/or services. A telephone  110  may be used to call the store  102  and make a purchase. The store  102  will have various retail terminals (see FIG.  2  and detailed below) that allow the store  102  to consummate the purchase. This includes accepting payment and, in accordance with the principles of the present invention, accepts and processes checks tendered for payment. The store  102  is typically in communication with an electronic network  106  that is in communication with a data warehouse  108 . Any digital receipt generated by the store  102  as a result of a purchase transaction may be sent over the network  106  to be stored in the data warehouse  108 . Another manner in which a consumer may purchase goods and/or services from the store  102  is by utilizing a telephone  110  to call in an order to the store  102 . 
     The business may also operate a web site  122  that is in communication with an electronic network  120  (i.e. the Internet). This provides another subsystem  130  in which a business may sell and the consumer may purchaser goods and/or services. The consumer, represented by the computer  112  (Internet enabled device), is typically in communication with the network  120  via an Internet Service Provider (ISP)  118 . In this manner, the consumer  112  may view the web site  122  and purchase goods and/or services therefrom. Payment for the goods and/or services may take any form such as credit/debit card or check. A check may be tendered as payment, typically before the goods arrive or when the goods arrive, such as by C.O.D. (cash on delivery). The web site  122  also generates a digital receipt for the purchase transaction. The web site  122  is in communication with the data warehouse  108  such that the digital receipts generated by the web site  122  may be transmitted to and stored therein. 
     As indicated above, the purchase transactions are typically accomplished by retail terminals. Retail terminals may take many forms. The retail terminal performs producing and/or formatting of the transaction data into the digital receipt. In particular, the retail terminal typically processes the transaction data into an electronic or digital form (e.g. an electronic or digital purchase transaction record). With reference now to FIG. 2, there is shown a retail terminal generally designated  10  that is representative of any retail terminal that is operable in accordance with the principles presented herein such as a point-of-sale, point-of-service, or a kiosk. The retail terminal  10  may be configured into any type of similar retail terminal as is known in the art. The retail terminal  10  may be of a consumer interactive type but not necessarily so. As such, the retail terminal  10  may be configured to perform a number of retail functions such as (i) a point-of-sale/point-of-service (POS) retail function, (ii) a product demonstration retail function, (iii) a data collection function, (iv) a passive display function, (v) an interactive, consumer query and answer function, and/or (vi) a bill payment/application access function or the like. Hereinafter, the retail terminal should be understood to include all types of retail terminals and consumer interactive terminals. The retail terminal  10  may be utilized to perform assisted and/or unassisted retail/interactive functions during an active or power-up mode as well as other function modes as described herein. 
     The retail terminal  10  includes a housing structure  12  that supports a display or monitor  18  for showing video or individual frames or screens depending on the particular mode of the retail terminal  10 . The display  18  preferably incorporates a touch-screen  19  as is known in the art that overlays the display  18  and allows user interaction in conjunction with material shown on the display  18 . Commonly, such displays are of the LCD type but may be any style or type. 
     The retail terminal  10  also includes a card reader  14  as is known in the art for obtaining information from a magnetic strip type card, or information from a smart card. The card reader  14  is adapted to obtain various identifying and/or account information from a user&#39;s card as in the known in the art and/or obtain information from a smart card. The retail terminal  10  is adapted to accept a PIN for a card inserted into the card reader  14  via a video generated keypad shown on the display  18  in conjunction with a touch-screen  19  (see FIG.  3 ). Other methods of obtaining a PIN, such as a mechanical keyboard as is known in the art, but not shown, may be used instead of a video generated keypad. The card reader  14  may thus be considered a payment device. 
     Additionally, the retail terminal  10  may include a speaker assembly  16  (see FIG. 3) that is preferably a stereo speaker assembly for playing music, audio messages and/or instructions and the like. Further, the retail terminal  10  includes a scanner  20  that is positioned to allow the scanning of a bar code or the like brought in proximity thereto. The scanner  20  may be any type of scanner or imager as is known in the art that is capable of capturing or imaging a bar code, graphics or the like. Such a scanner may be a laser type scanner, an LED type scanner, combination thereof, or the like as are well known in the art. 
     The retail terminal  10  also includes a cash acceptor device  22  that is adapted to receive paper money in various denominations, and thus constitute another type of payment device. A cash acceptor device  23  is adapted to receive coins for payment. The coin cash acceptor is preferably in addition to the paper cash acceptor  22  in order for a user to tender an exact amount of dollars and cents. A slip and/or receipt printer  28  is provided that prints receipts and/or accepts (i.e. receives and reads) checks tendered for payment. The printer  28  is also operable to frank (mark, print, or affix) the received check with a tender code per the principles presented herein, and either keep the franked check or return the franked check to the consumer. With card reader  14  the cash acceptor(s)  22  and  13 , and the slip printer  28  (collectively “payment devices”), the retail terminal  10  is adapted and/or configured to receive/accept payment from a user and function in accordance with the principles presented herein. 
     It should be appreciated that the retail terminal  10  shown in FIG. 2 may have other components that are not specifically mentioned herein but may be shown. These other components are generally known in the art. Additionally, the retail terminal  10  may be located anywhere either as a stand-alone self-contained unit, or as coupled to a network as a networked stand-alone terminal or workstation type unit. The principles of the present invention may likewise be incorporated into an existing retail unit/system. 
     Referring now to FIG. 3, there is depicted a block diagram of the various components of the retail terminal  10  and their interconnection(s). It should be understood that some components may be internal to the housing  12  of the retail terminal  10  and thus not shown in FIG.  1 . As well, the block diagram of FIG. 3 is applicable to other types of retail terminals, kiosks, and the like. 
     The retail terminal  10  has a processing unit or circuitry  24  as is known in the art that includes a processor or microprocessor and associated circuitry as the main controller for or of the retail terminal  10 . The processing unit  24  is in electronic communication with a typical power supply  30  via a power line  54 . The power supply  30  is coupled to a source of electricity (not shown) and is transformed appropriately as is known in the art for use by the processing unit  24 . 
     The card reader  14  is electronically coupled to the processing unit  24  via a communication line  48  that allows communication between the processing unit  24  and the card reader  14 . Information from a user&#39;s card is thus obtained by the card reader  14  and used/processed by the processing unit  24 . This may occur during ordering of a product and/or payment thereof, the retrieving of information. One manner of payment may be through a debit card, a charge card, a smart card, or the like (collectively “card”). Information from the card is obtained via the card reader  14 . 
     The display  18  is electronically coupled to the processing unit  24  via a communication line  44  that allows communication between the processing unit  24  and the display  18 . The display  18  is used to show various icons, graphics, windows, video, screens and/or areas (i.e. PIN entry area, billing application screen, etc.), and through the touch-screen  19  has capabilities that allow for user/consumer interaction with the retail terminal  10 . The touch-screen  19  overlays the display  18  and is in electronic communication with the processing unit  24  via communication line  46  to operate in conjunction with the display  18 . 
     Additionally, the speaker assembly  16  is also electronically coupled to the processing unit  24  via a communication line  50  that allows audio information (stereo or mono) to pass to the speakers. The audio information may be music, discourse (i.e. messages, instructions, answers to queries, or the like), or a combination of music and discourse. 
     Further, the scanner  20  is electronically coupled to the processing unit  24  via a communication line  52  that allows communication between the processing unit  24  and the scanner  20 . The scanner  20  is adapted to obtain a scan of a bar code and/or graphics on an object in proximity thereto such as a product, label or tag having a UPC (universal product code). In order to accomplish a scan, the consumer moves the object (e.g. product) thereunder such that the bar code on the object may be read by the scanner  20 . The scanner  20  is typically always in an active mode during normal operation of the retail terminal such that the bar code of an object will be immediately scanned or read when the object is placed thereunder. The scanner  20  may also read other information, coded or not, in various forms. 
     The retail terminal  10  may additionally include a motion detector  36  that is electronically coupled to the processing unit  24  via a communication line  58 . The motion detector  36 , in conjunction with the processing unit  24  and associated software, can be used to detect whether a customer is within a detection zone around the retail terminal  10  in order to allow the retail terminal  10  to perform an action or enter into a certain mode of operation. 
     As an example, the motion detector  36  and scanner  20  may work in tandem such that the scanner  20  is normally off when the motion detector  36  does not detect the presence of a consumer within the detection zone, but which activates the scanner  20  when a consumer is within the detection zone. After a predetermined time of inactivity, the scanner  20  may be deactivated until another triggering event has occurred (e.g. a consumer within the detection zone). As well, various types of motion of a consumer within the detection zone may trigger the scanner into activation. 
     The retail terminal  10  may include a hard drive  34  or other similar local or internal mass storage device that is in electronic communication with the processing unit  24  via a communication line  56 . The hard drive  34  may be used to store programs or the like, and any other information that allows the retail terminal  10  and its various components to function in accordance with the principles presented herein. The programs may be stand-alone programs for the operation of the retail terminal  10  or may be supplementary (e.g. modules) to main programs stored on the network  106 . The hard drive  34  may also locally store program instructions as described below that can be correlated to various purchase transaction data which is obtained/acquired during a purchase transaction that has transpired on the retail terminal  10 . This includes a check tender code generator operable to accomplish the features and/or functions described herein, and instructions to frank a check via the slip printer  28 , and provide the appropriate associations between the generated tender code and a generated digital receipt and the check. 
     As well, the processing unit  24  may be in communication with a memory device (or devices)  32  such as RAM or ROM via communication line  60  that may be used to temporarily or permanently store program/program instructions/modules/components and other information as is necessary for operation of the retail terminal  10 . The memory  32  may also store program information (programs/instructions) for the operation of the retail terminal and its components as described herein. Other program instructions required to carry out the various functions as described herein may also be stored therein. 
     A network card  38 , modem or the like (collectively network card) may be installed in the retail terminal  10 . The network card is in electronic communication with the processing unit  24  via a communication line  62 . The network card  38  allows the connection of the retail terminal  10  to the in-store processor  116  via network  114 . The network card  38  also allows connection to the Internet  138  (see FIG. 1) via the in-store processor  116  through the central office  120 . 
     The retail terminal  10  is in electronic communication with the receipt/slip printer  28  via a communication line  70  for providing a printout or hard copy of information regarding a transaction or transaction data during or after a purchase transaction such as a receipt or the like. As well, the printer  28  is operable to may print on the check a generated tender code or print a label having the generated tender code or to be applied to the check. In particular, the printer  28  preferably affixes the generated tender code to the received check, preferably by franking (marking or imprinting) either or both the front and back of the check. The memory  32  typically temporarily stores program instructions that are executable by the processing unit  24  in order for the retail terminal  10  to process the purchase transaction. 
     Processing of the purchase transaction via the retail terminal  10  includes the ability to scan and/or receive input data regarding a product or service, obtain, produce and/or generate various transaction data regarding the purchase, obtain payment for the purchase transaction, generate a digital receipt of the transaction, and generate a tender code when payment is made, or is to be made, by check. The transaction receipt may be provided on paper, but in accordance with the principles of the present invention, the receipt is preferably electronic or electronically formatted such as in digital form for transmission over a network. 
     The electronically formatted transaction record may be characterized as a digital receipt. In its electronically formatted (or digital) form, the transaction receipt may be transmitted over a network, or over various networked networks, to any device in communication with the network and adapted to receive such electronically formatted documents. Formatting and/or encoding of the transaction receipt may take many forms, of which many are known. The retail terminal may allow a consumer the option of specifying the type of formatting or encoding for the digital receipt in order to be compatible with the type of viewing program on the consumer&#39;s networked device (e.g. PC). In accordance with an aspect of the present invention, the digital receipt includes a tender code when payment is made by check. 
     With reference to FIG. 4, an exemplary digital receipt in accordance with the principles of the present invention and in human readable form is shown, generally designated  160 . The digital receipt  160  depicts the type of information that is obtained and/or generated during the purchase transaction (i.e. transaction data) and which may be included in the purchase receipt. The information included in the digital receipt  160  may be included in a paper receipt, if one is produced, for the transaction. 
     The digital receipt  160  may include the name of the merchant, retailer, store, or type of business and/or the like  162  (collectively “store”) and the time and date  164 . The digital receipt  160  may include a header that identifies itself, here “Purchase Transaction Record.” Store particulars  166  may also be included such as store number, street address (i.e. location), telephone and facsimile numbers. A product and/or service area  170  is provided that details the type of product, item or service (collectively “item”) purchased (either by full item name or by a truncated item name), the quantity of each item purchased, the unit price of the item, total cost of each quantity of item(s), the universal product code (UPC) or other identifier for the item, and a total number of items purchased. A costing area  172  includes the total cost of all items, a tax paid/data area  176 , and a total customer cost. The receipt  160  further contains a payment area  174  that includes the mode or method of payment used by the consumer (i.e. cash, check, credit card, debit card, etc.). If necessary, an amount tendered area and change due area are also included. 
     It should be appreciated that the transaction data or information shown on the digital receipt  160  is only exemplary of the many pieces of transaction datum that is obtained/generated by or during the purchase transaction. The structure, layout, and/or form of the digital receipt  160  is also only exemplary. The digital receipt is electronically formatted transaction data (i.e. compilation of transaction datum) that may be compiled, combined and/or assembled in various ways. 
     In accordance with an aspect of the present invention, the digital receipt  160  includes a tender code  180  that is formatted for electronic transmission over the network along with or appended to the digital receipt  160 . The tender code  180  is generated or produced by the retail terminal  10  when a check is tendered for payment for goods and/or services. The tender code  180  is associated with the digital receipt and the received check (see FIGS. 7 and 8) and may be stored in the retail terminal on which the purchase transaction transpired, or may be stored in the central office  120  to which the digital receipt  160  is transmitted from the retail terminal or on which the digital receipt  160  is compiled and formatted for transmission in the case that the retail terminal does not do so. 
     In accordance with an aspect of the present invention, when a check is tendered for payment, the retail terminal  10  produces or generates a tender code. The tender code is unique to the particular purchase transaction. The tender code is associated with the digital receipt  160  for that particular purchase transaction as well as being associated with the check tendered for payment such that the check tendered for payment is indexed to the digital receipt generated for the purchase transaction and/or the digital receipt generated for the purchase transaction is indexed to the check tendered for payment. Association with the digital receipt preferably takes the form of appending or attaching the tender code to the digital receipt. Referring to FIGS. 7 and 8, association with the check  300  preferably takes the form of imprinting, affixing, or the like, the tender code  302  onto the front  301  of the check  300  and/or imprinting, affixing, or the like, the tender code  304  on the back  303  of the check  300 . With regard to the digital receipt  160 , the tender code  180  is appended thereto and preferably becomes a part thereof as depicted in FIG.  4 . Thus, when the digital receipt  160  is forwarded and then retained in the data warehouse  120 , the particular check tendered for payment that is the subject of the digital receipt is indexed to the digital receipt by virtue of having the same tender code. The check  300  will, as well, be indexed to the digital receipt by virtue of the tender code being placed thereon as well. The consumer may then be able to correlate the particular check to the particular purchase and/or purchase transaction. 
     Thus, the retail terminal  10  prints the tender code directly on the check, either on the front or back. This indexes or correlates the check to the particular purchase transaction. If the retail terminal  10  does not include check imprinting capabilities, the tender code may be printed as a label or the like and attached to the check. In the case of CODs and other situations where a check is tendered after an order is received, the label and/or the tender code may be generated at the point of delivery. A PDA (personal digital assistant) may be used to perform such a function at the point of delivery. The PDA may as well generate the digital receipt that will be stored in the data warehouse  108 . 
     The tender code may be any type of coding that uniquely identifies the purchase transaction and check tendered for payment. The coding may be accomplished in a manner. The tender code may be encrypted if desired. As well, the tender code may include auxiliary information or data encoded into the tender code. Such auxiliary data may include a URL (Uniform Resource Locator) for the digital receipt within the data warehouse  108 . This would allow the consumer to access the information from the data warehouse  108  via their computer  112 . The tender code may be printed on the check in a machine readable manner. A device that can read the encoded tender code and/or the auxiliary data may be check processing transports or a clearing house may read the encrypted code to associate the check back to the digital receipt. As an example, such encoding may be a bar code. 
     This procedure is set forth in the flow chart of FIG. 5, and reference is now made thereto. In FIG. 5, a flowchart, generally designated  200  is shown. Initially, the consumer makes a purchase, step  202 . The purchase may be goods and/or services. The consumer then tenders payment for the purchase in the form of a check, step  204 . Payment may be in any form, but most particularly in the preferred scenario of which the principles of the present invention are best suited, payment is made in the form of a check. Thus, consistent with this exemplary scenario, the remaining steps a check will be assumed to be the payment form. However, it should be appreciated that the principles of the present invention apply to all forms of payment. 
     The retailer receives the check for the purchase from the consumer, and generates a tender code in response thereto, step  206 . This is preferably accomplished on a retail terminal (see above). A digital receipt is then generated by the retailer, step  208 . The tender code is a unique identifier that may or may not be encrypted. As well, the tender code may be generated so as to be machine readable. Once the tender code is generated, the tender code is associated with the check and the digital receipt, step  210 . The tender code is associated with the digital receipt by adding the tender code to the data that constitutes the digital receipt. As well, the tender code may be indexed to the digital receipt. The tender code is associated with the check by imprinting the tender code onto the check, printing a label or the like and affixing the same to the check, or any other means that puts the tender code onto the check. In the case of other methods of payment, the tender code may be printed onto a paper receipt or other evidence of purchase that the store may give to the consumer. Thus, when the consumer gets the check back from their banking institution (or as held by the bank), the consumer has evidence linking the check as payment to the digital receipt that is for the purchase transaction for the particular goods and/or services. 
     Next, the digital receipt is forwarded to the consumer and a storage device, step  212 . Forwarding of the digital receipt to the consumer is accomplished via e-mail or other similar means. The storage device is preferably a data warehouse that is in networked communication with the retail terminal. The check itself is forwarded to a clearing house, financial institution or the like, step  214 . The clearing house/financial institution clears the check (or returns same as unpaid) and updates the digital receipt with an approved transaction indication (or not approved as the case may be), step  216 . This may be accomplished by forwarding data to the data warehouse regarding the particular check as indexed to the digital receipt to add the transaction status data. The retailer may decide to manipulate or process the data from the purchase transaction. In this regard, the payment data, customer data, and/or the transaction data from the digital receipt (purchase transaction) are indexed to one another, and/or processed in various ways, step  218 . 
     Referring now to FIG. 6, there is depicted a flow diagram, generally designated  250 , of another exemplary manner in which the principles of the present invention may be employed. For purposes of this example, it will be assumed that payment is to be effected via a check. However, it should be appreciated that the principles of the present invention are applicable to other forms of payment. 
     A consumer accesses a web site of a business/retailer, step  252 , in a known manner. The consumer makes an on-line purchase  254  in accordance with the web site. Since it is assumed that the consumer will be paying by check, the consumer then has the option, step  256 , of sending the check or requesting C.O.D. If the consumer sends payment, the web site receives the check and generates a tender code, step  258 , as described above. A digital receipt is then generated (or at the time of generation of the tender code), and associated with the digital receipt and check, step  260 , as described above. Thereafter, the digital receipt is forwarded to the consumer and storage, step  214  (FIG.  5 ). 
     If the consumer elects “C.O.D.”, then a courier will bring the purchase to the consumer. The consumer pays the courier by check when the purchase arrives, step  264 . The courier then generates a digital receipt and tender code for the transaction, step  266 . Generation of the digital receipt and tender code in the field by the courier may be accomplished via hand-held computer controlled devices such as a PDA (personal digital assistant) and/or the like. The PDA may be linked to the business web site or will be forwarded to the business web site (i.e. the business) in due course. The tender code is then associated with the digital receipt and the payment, step  268 . Such associated may entail the printing of the tender code directly onto the tendered check by the PDA or other device, or may be printed on a label by the PDA or other device, and affixed to the tendered check. Thereafter, the flow continues in the manner of step  214  of FIG.  5 . 
     In step  266 , the courier may not generate the digital receipt and/or the tender code in the field, but may access the business instead to obtain the information. Such access may be via a network or the like. In this manner, the business maintains control of the digital receipt and the generation of the tender code. It should be appreciated that variations of the above two exemplary method in accordance with the principles of the present invention are contemplated and within the scope of this invention. As well, other steps may be incorporated into the exemplary methods, such as generation of a paper receipt for the consumer. 
     If the tender code is generated in a machine readable, a consumer may take the check or printed digital receipt to a device operable to read the tender code. This may provide access to the data warehouse, business web site, etc. regarding the particular purchase transaction/digital receipt. The consumer may then accomplish other business as necessary. 
     While this invention has been described as having a preferred design and/or configuration, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
