This invention relates generally to cashless transaction systems, and more particularly to stored value accounts and methods for using stored value accounts.
Stored value cards are available to consumers to be used in place of cash. The stored value cards may hold a value that has been prepaid by the user or by others to the issuer. The cards may work within standard widely accepted or targeted networks, such as credit card networks, or may be used in a closed loop environment, for instance by using internal terminals at participating merchant establishments.
Stored value cards offer little flexibility or functionality to users or merchants who accept the cards. Businesses do not gain any benefit from accepting a stored value card and therefore have little incentive to accept such a card as payment.
Additionally, the user gets little benefit from using the stored value card. The major benefit to users is that they do not need to carry cash or own credit cards in order to make purchases.
Additionally, the user may load the card with value and spend money in a first merchant establishment. If the user does not accurately and diligently record the expenditures in the first merchant establishment, the user will not know how much value remains on the card the next time the user attempts to use the card in a second merchant establishment. Assuming that the user has a budget in mind for each merchant establishment, if the user overspends the budget in one merchant establishment, the user will not have enough value to purchase products that the user desires or needs before reaching the second merchant establishment from which the user would purchase additional products. Other problems also exist.
It is therefore desirable to address the drawbacks in conventional stored value systems.
The invention overcoming these and other problems in the art relates, in one regard, to a stored value account. The invention relates to a stored value account including a general stored value field or purse and at least one stored value sub-field. The sub-field may represent a category and include category-specific benefits stored in the sub-field of the stored-value account. The account holder may be provided with an index to the account such as an account number or with a stored value instrument which stores either an account index, a value, or both.
According to another aspect of the invention, the category benefits may include discounts, loyalty points, merchant specific rebates or merchant promotions or other value or reward.
According to another aspect of the invention, the category represented by the sub-field may include a group of institutions, a location specific institution or a varied location institution.
According to yet another aspect of the invention, both a consumer client and an institutional client are capable of loading value into the stored value account through a load interface. Whereas the consumer client is typically able to load value into any account location, the institutional clients may be limited to loading value into a particular sub-field of the stored value account.
According to yet another aspect of the invention, a stored value system comprises a stored value account; an account access interface for permitting access by an institutional client and for permitting access by a consumer client; and an access mechanism for allowing access to the stored value account through the account access interface.
A consumer client 205 and an institutional client 203 are preferably linked to the stored value account 10 through an account access interface 250, which is explained in greater detail in
Sub-fields 14a-14n may hold benefits directed to one or more categories. In one embodiment, a category represented by one of the sub-fields 14a-14n may include an institutional client 203. Institutional clients 203 may include educational institutions, merchants, service providers, and others. The category of institution may include a group of institutions, location specific institution or a varied location institution. Categories representing a group of institutions may include airlines, fast food restaurants, grocery stores, sporting goods stores, universities, etc. The institutions may be represented by a category code. The category code may provide sufficient information to link the institution to its associated sub-field.
A location specific institutional client 203 may include a specific institution at a specific location. For example, the location specific institution may include a supermarket at the corner of 12th and 9th streets. In another embodiment, the location specific institution may be a specific academic institution such as a specific college or university.
The varied location institutional client 203 may include institutions having a plurality of locations. In one embodiment, the varied locations institution may include a merchant with a plurality of locations.
At least one of the sub-fields 14a-14n may be assigned a specific category. In one embodiment, the sub-fields 14a-14n may be variable so that the category may be changed. Thus, for a period of time, an account issuer 201 (shown in
The benefits provided in sub-fields 14a-14n may be downloaded into the stored value account 10 through a stored value network by the issuer of the card, as described below with reference to
When using the stored value account 10, if a consumer selects an establishment corresponding to one of the sub-fields 14a . . . 14n, the funds are withdrawn from that sub-field. If the selected sub-field 14 has insufficient funds, an embodiment of the stored value account 10 may access the general purse 12 for withdrawal of funds.
The benefits in sub-fields 14a-14n may include a discount in a certain category, loyalty points for a certain category, a rebate directed to a certain category, financial aid reimbursement in the academic institution category, or other special promotions in a certain category. The category specific benefits held in sub-fields 14a-14n may be negotiated by the issuer of the stored value account 10.
The discounts may include seasonal discounts to provide promotional savings. As an illustration, the promotional savings may include a special discount over sale rates for certain travelers traveling on a certain airline for during a predetermined time period. For example, transportation companies may offer a five percent discount to students traveling over spring break. This type of benefit allows stored value account holders to automatically receive a benefit for using the stored value account 10 without the need for a paper certificate. The benefit also allows institutional clients 203 to receive a benefit of a larger number of customers, by providing the discount, without having to market the discount.
In one embodiment, the benefits stored in sub-fields 14a-14n may include loyalty points. In this embodiment, a user may earn points towards gifts or prizes or products sold by the merchants by buying products or services from the merchant.
In one embodiment, a category specific stored value may be stored in sub-fields 14a-14n. For example, a stored value may be stored in a grocery store sub-field. Thus, the category specific stored value stored, for example, in sub-field 14a, may be used only at the category represented by sub-field 14a. Thus, if the category of sub-field 14a includes all the grocery stores in a certain area, defined geographically, the value stored in sub-field 14a may be spent only in the grocery stores in the defined area. In the example of a “campus card,” the grocery store category may include all grocery stores within a five mile radius of the campus. Continuing with the example of the campus card, the category specific stored benefits may include tuition for a specific educational institution or a group of educational institutions, restaurants in a campus area, campus sporting events, etc.
In another embodiment, the category specific stored value may be directed to location specific institutions, such as, for example, a specific drug store near a campus, the campus bookstore, a specific grocery store near a campus, a specific restaurant or dining establishment near a campus or on campus, etc.
The category specific benefits may also include other promotions. Other promotions may include item give-aways for a minimum purchase, promotions based on a user profile, promotions based on past user purchases, etc. For example, if an institutional client 203 has a large inventory of a specific item that needs to be sold, the institutional client 203 can negotiate with the issuer 201 of the stored value account 10 to offer discounts for the product to a predetermined subset of all of the users of the card. Additionally, the consumer clients 205 who receive the special may be consumer clients 205 who have bought that item before or consumer clients 205 having some indication in their profile that they would buy products or services from the institutional client 203. In another embodiment, the institutional client 203 may offer the overstock items to all consumer clients 205.
The consumer client 205 may be provided with the access mechanism 212 for accessing the stored value account 10. The institutional client 203 may include an access reader 211 for recognizing the access mechanism 212. Additionally, the issuer 201 may provide its own access readers 222 for recognizing the access mechanism 212.
The account access interface 250 as shown in
In one embodiment, issuer 201 may be linked to clients 203 and 205 via communications link 215. In other embodiments, there may be multiple servers 208 or more than two clients, 203, 205. In some embodiments, clients 203, 205 may be configured to perform all processing and storage functions which might otherwise be performed by the server 208 and the database 202, respectively.
In one embodiment, stored value account 10 may be implemented using a stored value card as the access mechanism 212, such as, for example a prepaid card. Stored value account 10 may be accessed through the use of a stored value card having a magnetic stripe or through the use of a virtual account number. In one embodiment, the stored value card 212 may be read by any access reader 211, 222. Access readers 211, 222 may be compatible with the Visa™ network or the MasterCard™ network and may not require entry of a personal identification number (PIN). Alternatively, the card 212 may be a private label card, which offers restricted use for a virtual or actual mall environment while operating out of a BIN (such as VISA/Mastercard). As another alternative, a closed loop card may be provided for use only within participating merchant establishments operating with a special network infrastructure. Additionally, the card 212 may be usable with a PIN through ATM or POS over networks such as Plus, Cirrus, and/or Interlink/Star network. In yet an additional alternative embodiment, only a virtual card is provided in the form of an index for accessing the account 10.
Issuer 201 may host applications facilitating financial transactions for banks, merchants or other entities. Such applications may be related to the transfer between accounts such as at account 10 for the conversion of currency or to the performance of other functions which may or may not be described herein. The server 208 of the issuer 201 may be or include, for instance, a workstation running the Microsoft Windows™ NT™, Windows™ 2000, Unix, Linux, Xenix, IBM AIX™, Hewlett-Packard UX™, Novell Netware™, Sun Microsystems Solaris™, OS/2™, BeOS™, Mach, Apache, OpenStep™ or other operating system or platform.
Additionally, server 208 may interface to database 202. Database 202 may contain the stored value accounts 10, financial account data, currency conversion rates, merchant information, user information, promotion information or other information as appropriate to the operation of the stored value system of the present invention. Database 202 may be, include or interface to, for example, the Oracle™ relational database sold commercially by Oracle Corp. Other databases, such as Informix™, DB2 (Database 2), Sybase or other data storage or query formats, platforms or resources such as OLAP (On Line Analytical Processing), SQL (Standard Query Language), a storage area network (SAN), Microsoft Access™ or others may also be used, incorporated or accessed in the invention.
Various configurations may be provided for loading and redeeming value from the stored value accounts 10. Three entities including the issuer 201, the institutional client 203, and the consumer client 205 may have access to the stored value account 10. Whereas the consumer client 205 may have virtually unlimited access to the stored value account 10, the issuer 201 and the institutional client 203 may have limited access. For instance, the institutional client 203 may be able to freely load value to the account 10, but may redeem value only at the direction of the consumer client 205 (such as when the consumer client 205 makes a purchase). The issuer 201 will typically provide account services as directed by the consumer client 205.
Institutional clients 203 may include an access reader 211 that is a customer terminal where the stored value in the account 10 is to be redeemed for cash or for purchase of goods or services. The issuer 201 may also provide an access mechanism 222 in the form or a customer terminal for redemption of cash. The customer terminals may be fixed or portable terminals owned or used by users of the system and method. The consumer client 205 may implement the access mechanism 212 to request these services from the access readers 211, 222. Additionally, services independent of the institutional client 203 and issuer 201 may also provide a compatible access reader. For instance, convenience stores may position such access readers inside the stores, in a manner similar to that currently used for ATM machines.
Furthermore, readers 211, 222 may be or include, for instance, an ATM (automated teller machine). Clients 203, 205 may also be or include a PC (personal computer) running the Microsoft Windows™ 95, 98, Millenium™, NT™, or 2000, WindoWS™CE™, PalmOS™, Unix, Linux, Solaris™, OS/2™, BeOS™, MacOS™ or other operating system or platform. Clients 203, 205 may include a microprocessor such as an Intel x86-based device, a Motorola 68K or PowerPC™ device, a MIPS, Hewlett-Packard Precision™, or Digital Equipment Corp. Alpha™ RISC processor, an Intel Pentium®, Pentium® II, or Pentium® III processor, a microcontroller or other general or special purpose device operating under programmed control. Access readers 211, 222 may furthermore include electronic memory such as RAM (random access memory) or EPROM (electronically programmable read only memory), storage such as a hard drive, CDROM or rewritable CDROM or other magnetic, optical or other media, and other associated components connected over an electronic bus, as will be appreciated by persons skilled in the art. Access readers 211, 222 may also be or include a network-enabled appliance such as a WebTV™ unit, radio-enabled Palm™ Pilot or similar unit, a set-top box, a networkable game-playing console such as Sony Playstation™ or Sega Drearncast™, a browser-equipped cellular telephone, or other TCP/IP client or other device. Access readers 211, 222 may also be, include or interface to a wired digital or analog telephone, or a wireless digital or analog telephone such as a cellular telephone or a satellite telephone.
In an embodiment of the invention in which the stored value account 10 is accessed through the use of a card, clients 203, 205 may also be, include or interface to the access reader 211, 222. Readers 211, 222 may be adapted to communicate over the links 215, 220 with the consumer client 205 having the account access mechanism 212. Together, access readers 211, 222 and links 215, 220 may effectuate the transfer of value from a terminal to the stored value account 10. In one embodiment, reader 211 and link 220 may facilitate that exchange of value in the stored value account 10 for goods, services, or cash. Although only one client 203 and one client 205 are shown, the system 200 may include as many clients 203, 205 as needed or desired.
There may be different embodiments of account access mechanism 212. In one respect, if the access mechanism 212 is a stored value card, different versions of the stored value card may differ as to materials used in fabrication. Both disposable and reloadable stored value cards may be made of paper, plastic, or any other suitable material. The stored value card 212 may contain at least one feature for storing data. In one embodiment, data may be stored on a magnetic stripe. Other embodiments may include electronic magnetic, or optical structure in the interior of the card. Data stored on the stored value card may include, for example, a name, an account number, numerical representation of value, an indication of categories stored in sub-fields 14a-14n, personal identification number, or other data utilized by the method or methods disclosed herein. In one embodiment, stored value card 212 may include a processor. The stored value card 212 may contain enough information merely to index the stored value account 10. Alternatively, the stored value card 212 may store additional account information relating to available funds in the purse area 12 and sub-fields 14.
The stored value card 212 may be physically or electronically configured in a way that is compatible with recognized industry standards, such as proton, mondex, common electronic purse specification (“CEPS”), or other standards familiar to those in the art of electronic accounts. The system is preferably capable of online real-time and extensible markup language (XML) transactions. In any case, stored value the card 212 should comprise a computer readable medium.
The term “computer-readable medium” as used herein refers to any medium that participates in providing instructions to the processor for execution. Such a medium may take many forms, including but not limited to non-volatile media, volatile media, and transmission media. Non-volatile media include dynamic memory, such as main memory. Transmission media include coaxial cables, copper wire and fiber optics, including the wires that comprise the bus. Transmission media can also take the form of acoustic or light waves, such as those generated during radio frequency (RF) and infrared (IR) data communications. Common forms of computer-readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, DVD, any other optical medium, punch cards, paper tape, any other physical medium with patterns of holes, a RAM, a PROM, an EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave as described hereinafter, or any other medium from which a computer can read.
In an alternative embodiment, the user may be provided only with an account access mechanism 212 that includes only an index to the stored value account 10. In this embodiment, the consumer client 205 possesses an account number or any alphanumeric which is linked to the account number in the database 202. In this embodiment, the access readers 211, 222 would not be required to read a card, but may instead include a keypad or other interface. The access mechanism could also include the consumer client's voice and the access reader 211, 222 would then include voice recognition apparatus. The access mechanism could also include an image, a thumbprint, or any other suitable identifying indices. The readers 211, 222 would then be provided with equipment for recognizing these unique indices.
Server 208, database 202 and clients 203, 205 may communicate with each other via communications links 215, 220. Communications links 215, 220 may be, include or interface to any one or more of, for instance, the Internet, an intranet, a PAN (Personal Area Network), a LAN (Local Area Network), a WAN (Wide Area Network) or a MAN (Metropolitan Area Network), a storage area network (SAN), a frame relay connection, an Advanced Intelligent Network (AIN) connection, a synchronous optical network (SONET) connection, a digital T1, T3, E1 or E3 line, Digital Data Service (DDS) connection, DSL (Digital Subscriber Line) connection, an Ethernet connection, an ISDN (Integrated Services Digital Network) line, a dial-up port such as a V.90, V.34 or V.34bis analog modem connection, a cable modem, an ATM (Asynchronous Transfer Mode) connection, or an FDDI (Fiber Distributed Data Interface) or CDDI (Copper Distributed Data Interface) connection. Communications links 215, 220 may furthermore be, include or interface to any one or more of a WAP (Wireless Application Protocol) link, a GPRS (General Packet Radio Service) link, a GSM (Global System for Mobile Communication) link, a CDMA (Code Division Multiple Access) or TDMA (Time Division Multiple Access) link such as a cellular phone channel, a GPS (Global Positioning System) link, CDPD (cellular digital packet data), a RIM (Research in Motion, Limited) duplex paging type device, a Bluetooth, BlueTeeth or WhiteTooth radio link, or an IEEE 802.11-based radio frequency link. Communications link 215, 220 may yet further be, include or interface to any one or more of an RS-232 serial connection, an IEEE-1394 (Firewire) connection, a Fibre Channel connection, an IrDA (infrared) port, a SCSI (Small Computer Systems Interface) connection, a USB (Universal Serial Bus) connection or other wired or wireless, digital or analog interface or connection. Communications links 215, 220 may further be, include, or interface to a PSTN (public-switched telephone network).
In some embodiments, the type of communication between system components represented by communication links 215, 220 may not be implemented in the same way. Moreover, in some embodiments, it may not be necessary that all components communicate with each other.
Server 208 and clients 203, 205 may utilize network enabled code in order to facilitate functionality in a network-based environment. Network enabled code preferably accepts XML packets in real time, but may also be, include or interface to, for example, Hyper text Markup Language (HTML), Dynamic HTML, Extensible Stylesheet Language (XSL), Document Style Semantics and Specification Language (DSSSL), Cascading Style Sheets (CSS), Synchronized Multimedia Integration Language (SMIL), Wireless Markup Language (WML), Java™, Jini™, C, C++, Perl, UNIX Shell, Visual Basic or Visual Basic Script, Virtual Reality Markup Language (VRML), ColdFusion™, Common Gateway Interface (CGI), Draft Five, Automated Clearinghouse (ACH), or other compilers, assemblers, interpreters or other computer languages or platforms.
The processes illustrated in
Steps 302, 303, and 304 are the value loading steps. These steps may occur in any order upon the establishment of the stored value account 10. In step 302 the issuer 201 may store a general value in the general field 12 as requested by the consumer client 205. In one embodiment, the consumer client 205 may request the issuer 201 to place a specific value in the general field 12 of account 10. In another embodiment, the consumer client 205 may choose from a plurality of possible values presented to the user by the issuer 201. In one embodiment, the consumer client 205 may choose not to place any value in the general field 12 of stored value account 10.
In step 303, the issuer 201 stores value in the sub-fields as requested by the consumer client 205. If the benefit to be stored in a sub-field 14a-14n includes a specific stored value for a specific institution, the issuer may store the amount of value directed toward the institution in one of the sub-fields 14a-14n. For example, the user may request that an amount of 200 dollars be stored in a grocery store sub-field 14a-14n when the user transmits a request for a stored value card 213 to the issuer 201. In other embodiments, the user may not have the option of storing a value in a category specific sub-field 14a-14n. Each sub-field 14a-14n may include an expiration period, such that if the consumer client 205 doesn't use the value provided by an institutional client 203 in a specific sub-field, the value may become unavailable as of a specified date.
In one embodiment, the issuer 201 may present the user with a plurality of choices for categories in which the user may store a value. The issuer 201 may then store the amount requested in the predetermined category specific sub-field 14a-14n. For example, the issuer 201 may store the $200 the user has requested to be stored in a grocery store sub-field in the sub-field 14a-14n designated to be the grocery store sub-field.
Thus, the consumer client 205 will ensure that at least a predetermined amount of stored value may be spent at a predetermined institution. For example, if the stored value account 10 is a campus account, a parent purchasing the stored value account 10 will be able to ensure that a college student will have enough money for groceries. For example, even if the student runs out of money in the general value field 12 of the stored value account 10, the student will still have the value stored in the grocery store sub-field. In one embodiment of the campus account, issuer 201 may negotiate a discount for some university events or all university events for a certain university. For example, users of the stored value account 10 may receive a 10% discount when attending a theatrical performance at a university.
Alternatively, the rules for the account 10 may be entirely established by the institutional clients 203. The institutional clients 203 may establish account parameters based on the behavior of consumer clients 205. The institutional clients 203 can provide initial funding for a sub-field 14a-14n or subsequently provide funding based on the behavior of the consumer clients
In step 304, the issuer 201 stores any initial value provided by institutional clients 203. Institutional clients 203 may in some instances provide incentive funds to be deposited in a sub-field in order to establish a new account or upon the establishment of each new stored value account 10. For example, the stored value account 10 may include a permanent benefit stored in a sub-field 14a-14n, such as, a permanent 5% discount for a certain merchant or a discount at spring break for a flight on a specific airline, if the consumer client 205 uses the account 210 to purchase an airline ticket during a predetermined interval.
In one embodiment, the issuer may negotiate with institutions to provide the benefits to account users. The categories 14a-14n may be variable, such as the airline tickets for spring break example above. In another example, in one promotional period, sub-field 14b may be used to provide users of the stored value account 10 with a promotion from a retailer. In another promotional period, sub-field 14b may be used to provide users with travel promotions, such as a free gift from an airline, hotel, gas station, or another travel-related merchant.
In step 305, the issuer 201 provides the account holder or consumer client 205 with an access mechanism 212 in order to access the stored value account 10.
Thus, a stored value account 10 provides issuers 201, institutional clients 203 accepting the stored value account 10 and consumer clients 205 of the stored value account 10 with flexibility and added function. Consumer clients 205 may receive exclusive savings or promotions from institutions. Institutional clients 203 may be able to dispose of excess inventory and market merchandise at lower costs. Issuers 201 may gain increased utilization and usage of the stored value account 10.
In step 406, the issuer 201 may receive a load request accompanied by an access mechanism from either a consumer client 205 or an institutional client 203. The consumer client 205 may wish to load additional value to the account 10. Alternatively, an institutional client 203 may be processing a purchase from the consumer client 205 and decide to provide the consumer client 205 with a present or future discount. Under either of these circumstances, the appropriate client provides the issuer with an access mechanism 212 in step 406 and the issuer 201 determines whether the access mechanism correctly matches the stored value account in step 408. If there is no match, the issuer allows repeat attempts in step 410 until the maximum number of failures has been reached in step 412.
If the issuer 201 finds that the access mechanism is correct in step 408, the issuer determines whether the consumer client 205 or institutional client 203 has designated a sub-field in step 414. If no sub-field is designated, the issuer 201 stores the value in the general purse in step 416. If a sub-field is designated, the issuer 201 stores the value in the sub-field in step 418.
As set forth above with reference to
If the issuer 201 verifies the access mechanism 212 in step 504, the issuer 201 determines in step 510, whether the request is linked to a particular sub-field 14. If the request is not linked to a sub-field 14 in step 510, the user 201 accesses the general purse 12 in step 512. In step 514, the issuer 201 determines whether the general purse 12 contains sufficient funds. If the general purse 12 does not contain sufficient funds, the issuer 201 reports the insufficient funds in step 516. If the general purse 12 does contain sufficient funds, the issuer 201 fulfills the redemption request in step 518.
If the request is linked to a sub-field in step 510, the issuer 201 accesses the sub-field 14 in step 520. In step 522, the issuer 201 determines if the sub-field has sufficient funds. If the sub-field has sufficient funds in step 522, the issuer 201 fulfills the redemption request in step 532. If the sub-field 14 does not have sufficient funds in step 522, the issuer 201 accesses the general purse 12 in step 524. If the issuer 201 finds sufficient funds in the general purse 12 in step 526, the issuer 201 may report lack of sufficient sub-field funds, but nevertheless fulfill the redemption request through the use of funds in the general purse 12 in step 530. This particular feature may or may not be present in other embodiments of the method of the invention.
If the issuer 201 does not find sufficient funds in step 526, the issuer 201 may report insufficient funds in step 528 and terminate the process. In an alternative embodiment, the issuer 201 may inform the consumer client 205 that insufficient funds are available and then provide the consumer client 205 with an opportunity to supplement the available funds. The consumer client 205 may use a credit card, account transfer, or other funding source to add value to the account 10 in order to complete the purchase. The added value preferably supplements existing funds so that the account 10 has exactly enough value to complete the purchase.
The stored value system preferably includes a mechanism for sending a statement to the consumer client 205 on a periodic basis. The statement identifies the source of funds available in the stored value account. Accordingly, through viewing the statement, the consumer client 205 will be able to determine that a specific institutional client 203 has added value to the general field 12 or to one of the sub-fields 14a-14n.
In summary, the invention provides a stored value system valuable to both consumers and institutions. Both entities receive considerable benefits from using the stored value system.
