This application relates generally to a system and method for conducting purchase benefit transactions at a point of sale by means of biometric authorization. More particularly, the present invention relates to a system and method for allowing individuals to authorize purchase benefits, such as rebates, warranties, and consumer rewards, biometrically at a point of sale.
Generally, an individual conducting a purchase benefit transaction, such as a rebate, a warranty, or a consumer reward, has to undertake several steps once the associated item has been purchased. A consumer may have to obtain and complete a form, locate the relevant receipt, and/or retrieve a product identifier, such as a universal product code (UPC), and mail this information to the benefit provider. A consumer may easily misplace rebate forms and receipts, discard product packaging before retrieving product identifiers, or simply forget to take the steps necessary to complete the purchase benefit. Even if consumers complete the required steps, they may not obtain the desired results. For example, mailed rebate checks are often unclearly marked and may be discarded as junk mail. In regard to warranties, consumers often have no way of verifying if their registration information reached the benefit provider. What is needed are better systems and methods for conducting purchase benefits.
The present invention addresses the aforementioned needs by providing users with an accessible system and convenient method for conducting purchase benefit transactions. When enrolling in a biometric authorization system, a user may authorize the system to apply for purchase benefits on the user's behalf at subsequent transactions.
In order to describe the manner in which the above-recited and other advantages and features of the invention can be obtained, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments thereof that are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
Various embodiments of the invention are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without parting from the spirit and scope of the invention.
As aforementioned, the present invention provides a system and method for biometrically conducting purchase benefit transactions. A purchase benefit transaction may be a rebate, a warranty, a consumer reward, or the like provided to a user in association with a purchased item. Typically, purchase benefits are offered by a benefit provider, which may be a payor or a warrantor, such as a manufacturer or third-party intermediary. Benefit providers offer purchase benefits for numerous reasons. For example, offering a rebate may entice a consumer to purchase a product because of a promised refund. However, due to the numerous post-transaction steps required, users may not complete the rebate transaction and may not obtain the refund. By not receiving rebate forms and transaction information, benefit providers do not obtain valuable customer data. Similarly, users may not complete the necessary steps for warranty registration. Typically, a user must fill out a warranty registration card and send it to the benefit provider. Such registration cards are often discarded or overlooked by users and, thus, the benefit provider does not acquire the customer data that warranty registration can provide. Warranty registration may be particularly important if the benefit provider needs to issue product recall information. In addition, other consumer rewards may suffer difficulties similar to those mentioned.
The present invention addresses the aforesaid needs by associating purchase benefit transactions with a biometric authorization system (BAS). User transaction information is stored in one or more electronic records that are associated with a user's biometric data. Transaction information may be stored in an electronic record during or after a transaction. Additionally, transaction information may be converted from physical form (e.g., a paper receipt) to electronic form at a system device, or may be retrieved from one or more storage locations. Regardless of how transaction information is entered into the system, it is stored in electronic form and in association with user biometric data. Depending on the embodiment of the system, stored transaction information may be organized according to varying forms. For example, transaction information may be grouped by transaction, by an item/service identification code, by an item/service related department, by a product identifier, by price, by user, by merchant, by merchant location, by benefit provider, and/or by item/service description.
Storing transaction information in electronic form and in association with user biometric data allows a user to conduct purchase benefit transactions based upon the stored transaction information simply by presenting a biometric. Because most benefit providers currently require individuals to present physical transaction documents (such as receipts, forms, product identifiers, and the like) in a purchase benefit transaction, the present invention provides users with a more convenient method of presenting transaction documents by presenting their electronic transaction records in lieu of traditional physical documents. The present invention also provides users with greater privacy, allowing them to conduct purchase benefit transactions without necessarily having to send their personal information to benefit providers through insecure means, such as via a postal service. For example, warranty registration forms containing personal information are often postcards that may be easily read by mail handlers. Additionally, the invention provides a more secure form of conducting purchase benefit transactions by associating user biometric data with a transaction. Allowing users to present electronic transaction records in a purchase benefit transaction eliminates the need for users to keep track of and present traditional physical transaction records, such as paper receipts, during a purchase benefit transaction.
A user conducts transactions in the BAS by presenting biometric data that is compared to registered biometric data stored at a database. Matching user biometric data to a registered biometric data enables the retrieval of information stored in association with the registered biometric and/or approval of an authorization request depending on the action the user requests in the system. User biometric data may be received by the BAS from a variety of sources, such as from the user directly or from a third-party source, such as a database, token, or the like. In general, a biometric authorization refers to an authorization in which the user provides biometric data to be matched against a biometric record in a database. For example, a user may undergo biometric authorization to complete a financial transaction or to gain access to an age-restricted location. As would be appreciated, the location of the database as well as the specific mechanism by which the biometric data is matched to a particular biometric record would be implementation dependent and would not limit the scope of the present invention. Thus, in a biometric authorization, the biometric data taken during the authorization can be matched against registered biometric data at a location where the registered biometric data is stored or where the authorization biometric data is gathered. In addition, biometric data received during an authorization may be tested for liveness to prevent system fraud. Alternatively, the BAS may provide non-biometric access for users who have nonviable biometric data or for users who wish to employ the BAS without the use of biometric data.
Depending on the embodiment, the system may also provide a registered user with a system identification number (SID). An SID may serve as an identifier that can be used with or without user biometric data to aid the system in locating the storage location of a user record. Depending on the embodiment of the system, an SID may also serve as a user group identifier that identifies a user as an affiliate of a specified group of users.
Additionally, the principles of the present invention are not limited to using one form of biometric. For example, the biometric data referred to throughout this description can represent a biometric image (or sample) and/or a mathematical representation of the biometric image, often referred to as a biometric “template”. In one example, a biometric template can represent any data format that includes feature, positional, or other representing information of characteristics of biometric data. Alternatively, a template may be a mathematical representation of more than one biometric. For example, a user template may be generated from biometric data acquired from two individual fingers, such as a thumb and index finger, or from a finger and an iris scan. The biometric data may include fingerprint data, iris data, facial data, voice data, retinal data, hand architecture data, DNA data, or any other physical measurement pertaining to a user's person.
Benefit provider database 108 may store information pertaining to the purchase benefits transactions. Depending upon the embodiment, benefit provider database 108 may be a manufacturer's database, a third-party database, or a combination thereof. Benefit provider database 108 may store information necessary for purchase benefit transactions, such as user information, purchase benefit information, product information (e.g., price, product identifier, and the like), and merchant information.
A system user record holds system user biometric information and other identity verifying information related to an individual seeking biometric authorization within the system. The information held in such a record may include, by way of illustration and without limitation, a system user's government identification number(s) and corresponding state(s) of issue, home address, email address, a telephone number, and at least one biometric record. When enrolling in BAS 100, a system user may present any number of identity verifying documents or testaments to his identity depending on the implementation of the biometric system. By way of illustration and not of limitation, examples of such documents or testaments include a financial token, a digital image, a video clip, family information, or a DNA sample. Depending on the particular implementation, a system user record can also hold financial account information and/or a user identifier, such as an SID.
A system operator record holds information useful for authenticating an operator, such as a name or ID number, device ID numbers associated with the operator, an address, and a phone number. A system operator may be an individual or entity that has administrative capabilities in a BAS. These capabilities may range from being permitted to oversee a biometric authorization to having access to user records. For example, a system operator may be a store clerk, a merchant, or a system provider administrator. In an alternate embodiment of the present invention, the operator records also hold employer information if the operator is an employee of an employer who is also an operator. In another embodiment of the present invention, operator records hold an operator identifier, such as an SID, and/or operator biometric data. In one scenario, a system operator may need to undergo biometric authorization before administering a user's biometric authorization.
Database 104 and benefit provider database 108 are connected to network 102, which may be, but is not limited to, the Internet. Network 102 comprises connections to at least one authorization station 106 where a system user may be biometrically authorized. Authorization station 106 includes at least one biometric input device (BID) and the necessary means for sending and receiving information to and from a system user and to and from a database. These stations include but are not limited to a vending machine, a kiosk, a personal computer, a user service desk, a point of sale terminal, a telephone, or a wireless device connected via a wireless network. The BID is illustrated in
Additional embodiments of the system also comprise connections to one or more third party sources in which system user information, including user biometric data, is verified and/or from which system user information is retrieved. In an additional embodiment, the system may be connected to one or more financial sources in order to facilitate financial biometric authorizations. For example, a system user record stored at database 104 may indicate an account held at a financial institution that is to be debited during a biometrically authorized purchase.
Information transferred in the system may be encrypted. For example, information may be encrypted at one point and sent across a non-secure connection between points or not encrypted at a point of communication and sent to the other point of communication across a secure connection. Encryption and decryption of these messages may be monitored by services provided by a security company such as VeriSign. In one scenario, as an added level of security, information internal to a terminal and which is never transmitted may also be encrypted. This prevents retrieval of sensitive information (e.g., biometric data) from a stolen terminal. In an additional embodiment, the system incorporates one or more anti-tampering methods by which to recognize authentic and non-authentic system requests.
In one embodiment, the system is configured as an “open” system, where all information entered into the system is transmitted to and stored in database 104. An open system allows authorization at any authorization station 106 in the system because an open system shares system user information stored in database 104 with all stations.
In an alternate embodiment, the system is configured as a “closed” system, where information entered into the system via a specific operator device is transmitted to and stored in database 104 specific to that operator, and this information is not shared with other authorization stations or other databases. This is referred to as a “closed” system because system users need to enroll in the database in which they would like to perform biometric authorizations. Database 104 in closed systems may communicate with other databases, such as a third-party database or benefit provider database 108. However, all system user information that is enrolled into a particular database is stored in that database. In an alternate embodiment of the closed system, information is stored in a partitioned database 104. System operator related information is stored in system operator-specific partitions and is closed to all other system operators. Only an authorized system operator and authorized entities may access that partition of database 104. In yet an additional embodiment, information stored in one database or database partition may be stored in another database or database partition. Such an embodiment is useful for information protection in the event database information is lost.
In a further embodiment of the present invention, system user information is “selectively shared” and stored in select system multiple-operator databases or select system multiple-operator partitions within database 104. In this embodiment, a group of system operators share data with each other and they can choose whether or not to share system information with other system operators within the system. Such a system is referred to as a “selectively shared” system. This system allows a chain of system operators owned by the same entity or linked in some other manner to share system user information amongst them without sharing that information with all other non-designated system operators registered in the system. Information in such a system may be shared between one or more databases freely or sharing may be monitored by rules set in the one these databases or a combination thereof. By way of illustration and not as a limitation, one system operator might only want to share system user authorization information with one of five system operators in a multi-verifier system or all system operators might not want to send or store system user authorization information to database 104. Such a system allows system operators greater control over information flow while still allowing various user conveniences, such as being able to undergo biometric authorization at any store in a selectively shared chain.
The configuration of the system as an “open” system, “closed” system, or “selectively shared” system illustrates various ways of implementing the principles of the present invention. System configuration might be determined by the system in which user information is used. For example, a merchant who is an operator in the system and who conducts biometrically authorized customer loyalty programs might have a system configured with his own database and authorization stations connected to that database. In this system configuration, the merchant's database files only exist on the database and are retrieved or accessed for biometric authorization only by pre-determined stations connected to the database; therefore, the system would be a “closed” system.
In one embodiment, accepting the authorization agreement provides BAS 100 with legal authority to act upon the user's behalf. Depending upon the legal requirements of a purchase benefit and/or a benefit provider, BAS 100 may need such authority. Additionally, this arrangement may allow BAS 100 to provide additional conveniences to users. For example, a benefit provider may wish to send a rebate check to a user, however, because BAS 100 is applying for the benefit on the user's behalf, the check may be sent to BAS 100, which may in turn deposit the check in the user's financial account. Alternatively, the authorization agreement may provide an affiliated third party with legal authority to act upon the user's behalf.
At step 204, the system obtains user biometric data as consent to the authorization agreement. By consenting to the authorization agreement, the user preauthorizes BAS 100 to apply for benefits on his behalf In one embodiment, BAS 100 may apply for benefits on the user's behalf only if the user agrees to certain conditions. For example, the user may be required to allow one or more benefit providers to access the user's information for marketing research, product information, or the like. Alternatively, a user may select from among various degrees of compliance, wherein a user's selected level of compliance would determine the quality of a purchase benefit transaction fulfillment. For example, users that authorize a benefit provider to send them advertisements may receive a larger rebate offer than those who do not.
Upon consenting to the authorization agreement, at step 206 a user may configure purchase benefit parameters. Purchase benefit parameters may detail the user's preferred methods for conducting purchase benefit transactions. The user may configure purchase benefit parameters in which BAS 100 applies for all purchase benefits on the user's behalf automatically. For example, during the purchase of an item predisposed for a purchase benefit, BAS 100 may receive transaction information, including the user's biometric data, from a system operator. This information may be received per transaction or per item, or transaction information may be sent in a batch file at a time established by a system operator or BAS 100. Upon receiving the transaction information, BAS 100 may retrieve user information from the user's record and apply for the purchase benefit on the user's behalf.
Alternatively, the user may configure purchase benefit parameters in which BAS 100 requests user approval before conducting purchase benefits on a per-transaction or per-item basis. For example, after enrolling in BAS 100 and consenting to the authorization agreement, the user may purchase an item predisposed to a purchase benefit. During the purchase, BAS 100 may receive transaction information, including the user's biometric data, from a system operator. At the point of sale, the system may notify the user of the purchase benefit and request the user's approval to apply for the purchase benefit. The user may provide approval by presenting biometric data or through another appropriate method. In addition to approving the current purchase benefit transaction, the user may authorize BAS 100 to conduct subsequent benefit transactions of the same nature automatically.
The user may configure BAS 100 to apply only for one or more particular types of purchase benefits. For example, the user may preauthorize BAS 100 to handle all rebate transactions but not warranty registrations. In another scenario, the user may configure BAS 100 to apply for benefits for particular merchants, manufacturers, merchant groups, product types, or the like. For example, a user may preauthorize BAS 100 to conduct purchase benefit transactions for all Best Buy purchases but not for Wal-Mart purchases. In another illustration, the user may configure BAS 100 to conduct warranty registrations for electronics purchases only.
Additionally, a user may specify the method for purchase benefit fulfillment. For rebate transactions, the user may designate how rebate money is to be received, such as via a mailed negotiable instrument, cash at the point of sale, a store-credit token, a store-credit account, a deposit into one or more financial accounts, or the like. In one scenario, the user may allocate a portion of a rebate value to a charitable organization. If a system operator provides a user with a rebate value immediately (e.g., cash or store-credit), BAS 100 and the system operator may have a payment relationship wherein BAS 100 reimburses the system operator for the rebate value dispensed. In one scenario, the user may establish payment preferences, wherein a user establishes preferred methods of purchase benefit completion. For example, a user may specify that rebate refunds be deposited into a financial account as the preferred method. If this method is unavailable, the system may use the user's secondary preferred method and so on. BAS 100, benefit provider, and/or system operator may have the authority to disregard or override a user's preferences. For example, although a user has not specified receiving a rebate check by mail as one of his preferences, a benefit provider may have authority to disregard user preferences and provide the rebate as a check via mail. During preference configuration, BAS 100 may notify users that such preferences do not guarantee benefit provider compliance.
Once the user has consented to the authorization agreement and established purchase benefit parameters, BAS 100 stores the benefit authorization agreement, purchase benefit parameters, and user information, including user biometric data, in a user record at step 208. The user record may be accessed at subsequent biometric authorizations and a user may reconfigure purchase benefit parameters by updating his user record via an authorization station.
If the system determines that purchase benefits are available for one or more items, BAS 100 presents the user with an authorization agreement at step 304. The presentation of the authorization agreement would be implementation dependent and would not limit the scope of the present invention. In one scenario, the authorization agreement may be provided on a point of sale terminal screen. In another scenario, the agreement may be printed during the transaction and presented to the user. The system may present an authorization agreement for each applicable item, a select number of items, or for all the applicable items.
At step 306, the system obtains the user's biometric data. In one embodiment, the biometric data provides consent to one or more authorization agreements. In another embodiment, the user consents to the authorization agreement by selecting an option from a display terminal. Alternatively, the user may consent to the authorization agreement by signing a paper form.
At step 308, BAS 100 determines if the user's biometric data matches registered biometric data stored at database 104. In one embodiment, if the user's biometric data does not match registered biometric data, BAS 100 does not conduct a purchase benefit transaction on the user's behalf. In another embodiment, if the user's biometric does not match, the user is prompted to enroll in BAS 100 and the system may conduct one or more purchase benefits once enrollment is complete. The user may enroll at the point of sale or the user may suspend the purchase transaction until enrollment has been completed at a separate authorization station.
If the user's biometric data matches registered biometric data stored in a user record, the user information in the user record is retrieved at step 310. Retrieval may occur immediately or at a subsequent time as to be determined by implementation. The particular user information retrieved may be dependent upon the type of purchase benefit being processed. For example, BAS 100 may retrieve financial account information for a rebate transaction but only contact information for a warranty registration.
At step 312, the retrieved user information is sent to the benefit provider for processing. As aforementioned, a benefit provider may be a payor or a warrantor, such as a manufacturer or third-party intermediary. The benefit provider may then process purchase benefit transaction. If the user has established one or more purchase benefit parameters, they may be applied during processing. Alternatively, the benefit provider may conduct the benefit transaction according to its own guidelines.
In one embodiment, BAS 100 may provide a user with manual assistance for purchase benefit completion. Such assistance may be necessary if BAS 100 cannot accomplish one or more steps necessary for purchase benefit completion. In one scenario, BAS 100 may provide the user with one or more preprinted forms, such as a pre-addressed envelope, a rebate form pre-printed with user information, a warranty form pre-printed with user information, or the like. For example, a benefit provider may require the physical product identifier (e.g., UPC) from an item in order to authorize a rebate. BAS 100 may provide the user with an envelope pre-addressed with the benefit provider's address to assist the user in the mailing of the product identifier. The pre-addressed envelope may be provided at the time of sale or the user may print the envelope via a web site affiliated with BAS 100. Alternatively, BAS 100 may provide a pre-addressed label or slip that may be attached to an envelope.
In an additional embodiment, a purchase benefit transaction may require multiple user participation before completion. For example, in order to be eligible for a rebate, multiple users may need to perform a particular action. A set number of users may have to buy a particular item in order for the participating users to receive the rebate.
In another embodiment, users may access their user records to alter information pertaining to benefit transactions that have been processed or are in processing. For example, a user may change residences and may need to update personal information, such as his address, at an authorization station to ensure warranty registration information is accurate or that a rebate check is delivered properly.
In yet another embodiment, transaction information and purchase benefit information stored at database 104 may be used for product identification and transfer. In one scenario, a user may transfer a warranty successfully registered via BAS 100 to another individual by providing the new owner's information at an authorization station. Alternatively, a user may wish to designate that a rebate refund be sent to another individual. A recipient of the purchase benefit transfer may or may not be enrolled in BAS 100. If a recipient is not enrolled, the user may designate the recipient by identification information, such as phone number and/or address. If the recipient is enrolled in BAS 100, the user may be able to locate the recipient via the system by providing identification information, such as name, phone number, address, user identifier (e.g., SID), or the like. In an alternate embodiment, a user may assign a purchase benefit to another individual during a purchase transaction.
In additional embodiment, BAS 100 may assist with return and exchange transactions for purchase benefit items. Transaction information stored in BAS 100 may denote that a rebate refund has been paid for an item and notify a system operator that this amount should not be included in a return or exchange value. Alternatively, if a user exchanges one product for another, the system may notify the user and/or system operator that warranty information needs to be transferred to the new product or the system may transfer such information automatically. Transaction information may be located via a user's biometric data, user identifier (e.g., SID), a product identifier, or other identifying information. By employing a product identifier, the system may locate transaction information even if the item was conveyed to another individual as a gift.
In one embodiment, a radio frequency identification (RFID) may serve as a product identifier. A purchase benefit item may have a unique RFID to assist in purchase benefit issues. Because an RFID is unique, the system may confirm that a product being exchanged or returned is the actual product that was purchased. Additionally, transaction information may designate whether the product was actually purchased and not stolen. Furthermore, as aforementioned, an authorization station may be a wireless device (e.g., cell phone). Such a device may be equipped with an RFID reader and receive purchase benefit data for an item.
In an additional embodiment, a system operator may charge a service fee for purchase benefit transactions. A system operator may view that a service fee is appropriate for the convenience provided or to account for fees charged by BAS 100. The fee may be applied to the total purchase price, applied to the price for a purchase benefit product or, if applicable, may be deducted from a rebate refund. The fee may be a flat charge, be based on a percentage, or a combination thereof. Alternatively, a system operator may charge BAS 100 a fee for allowing it to manage a purchase benefit transaction or may charge both BAS 100 and the user.
In an additional embodiment, BAS 100 may provide one or more reminders to a user to ensure that a purchase benefit is completed. In one scenario, BAS 100 may provide reminders if a benefit provider does not participate with BAS 100. A reminder may be presented to the user in a variety of ways, such as email, a phone call, a mailed notification, or the like. In one scenario, a reminder may prompt the user to complete a purchase benefit process and may provide instructions and other pertinent information. A reminder may be sent once or multiple reminders may be sent on a periodic basis. In one scenario, once a user receives a reminder, he may be given the option to be reminded again later. For example, the user may receive an email reminding him to complete a rebate transaction and stating that a reminder will be sent every week until the rebate is completed. If the user desires to stop receiving the email reminders, the email may provide instructions for reminder cancellation.
In another embodiment, BAS 100 may present one or more purchase benefits provided by one or more benefit providers and one or more secondary providers. A secondary provider may be a system operator, such as a merchant, or an independent benefit provider. In one scenario, a user may select the standard purchase benefit, select the secondary purchase benefit, or a combination thereof. To receive a secondary purchase benefit, a user may have to pay an additional fee. For example, BAS 100 may offer an extended warranty from a secondary provider in addition to the benefit provider's warranty. The secondary benefit may be presented at the time of purchase or via a later notification (such as mail, email, at a later purchase, or the like).
As aforementioned, in addition to rebates and warranties, a purchase benefit may be another consumer reward offered by a benefit provider. A consumer reward may be an offer or promotion presented to entice a user to purchase an item or to provide further benefit once the item has been purchased. For example, a consumer reward may be access to a gift, a subscription to a periodical, an extended warranty, a preferred repair location, peripheral information, a replacement manual, or a troubleshooting contact. In one scenario, the benefit provider may offer such items and services to entice users to agree to receive marketing information. In one embodiment, BAS 100 may offer consumer rewards to encourage users to utilize the system.
In another scenario, a purchase benefit may be a value-added tax (VAT) refund. For example, a traveling user may make a purchase at Harrods in London and employ BAS 100 to receive his VAT refund. Information stored in a user record in BAS 100 may be used to complete the form(s) necessary or the user may manually complete the appropriate form(s). In one scenario, forms and/or identification documents (e.g., identification token, passport, and the like) may be imaged and electronically stored at database 104. The VAT refund may be received as stipulated by a user's purchase benefit transaction parameters. For example, the VAT refund may be deposited in a user financial account or mailed to the user as a negotiable instrument. Alternatively, the user may be required to retrieve the VAT refund at a specified location. In one scenario, a user may undergo biometric authorization before retrieving the VAT refund.
In an additional embodiment, BAS 100 may filter information sent to a user from a benefit provider so that only pertinent information reaches the user. In one scenario, a user that has elected to receive email notifications from a benefit provider may authorize BAS 100 to filter marketing material from the benefit provider. For example, a user may register a warranty on a car seat in order to receive recall information via email, but may not want to receive marketing offers, coupons, and the like. BAS 100 may filter such email to ensure that only recall information is delivered to the user. In another scenario, the user may authorize BAS 100 to filter postal mail from the benefit provider.
