System and method using merchant token

Abstract

A merchant computer generates a token including a “pay-me” merchant account identifier and transaction data for a transaction conducted by a consumer. The merchant token can be obtained by a mobile communication device and transmitted to a payment processing network along with a device identifier for the mobile communication device and an authentication token provided by the consumer. The payment processing network can authenticate the device using the authentication token, retrieve a consumer account number based on the device identifier, and complete the transaction by pushing money into the merchant “pay-me” account from the consumer account.

Description

BACKGROUND

In a typical electronic payment transaction, a consumer provides an account number to a merchant to conduct a financial transaction and the merchant requests a payment processing network to debit (i.e., “pull”) money from the consumer's account to the merchant's account. For example, in a transaction, a merchant can generate an authorization request message using the consumer account information and transaction information and can send it to an issuer for authorization. If the transaction is authorized by the issuer, money for the transaction may be transferred to the merchant account from the consumer's account at the issuer. However, in such transactions, the consumer's account information could be compromised (e.g., by unscrupulous merchants, merchant employees, identity thieves, etc.). Better ways to secure consumer account information would be desirable.

Embodiments of the invention address these and other problems, individually and collectively.

BRIEF SUMMARY

In embodiments of the invention, a merchant computer can generate a token including a “pay-me” merchant account identifier and transaction data for a transaction conducted by a consumer. The merchant token can be obtained by a mobile communication device and transmitted to a payment processing network along with a device identifier for the mobile communication device and an authentication token provided by the consumer. The payment processing network can authenticate the mobile communication device using the authentication token, retrieve a consumer account number based on the mobile communication device identifier, and complete the transaction by pushing money into the merchant “pay-me” account from the consumer account.

One embodiment of the invention is directed to a method comprising receiving, by a mobile communication device, a merchant token from an access device for a transaction. The merchant token comprises a merchant account identifier (e.g., for a merchant credit only account), and transaction data. The method further comprises receiving, by the mobile communication device, an authentication token from a consumer operating the mobile communication device, and generating, by the mobile communication device, a transaction request message comprising the merchant token and the authentication token. The method further includes sending, by the mobile communication device, the transaction request message to a server computer, and receiving a confirmation message that the transaction has been processed.

Another embodiment of the invention is directed to a mobile communication device that is configured to perform the above-described method.

Another embodiment of the invention is directed to a method. The method comprises receiving, by a server computer, a transaction request message comprising a merchant token comprising a merchant account identifier, transaction data comprising a transaction amount, and a mobile communication device identifier or a consumer account identifier. The method also includes generating, by the server computer, an authorization request message comprising the transaction amount and the consumer account identifier, and sending, by the server computer, the authorization request message comprising the consumer account identifier to an issuer computer operated by an issuer that issued the consumer account identifier. The method also includes receiving, by the server computer, an authorization response message from the issuer computer comprising the consumer account identifier, and replacing, by the server computer, the consumer account identifier with the merchant account identifier to create a modified authorization response message. The method also includes sending, by the server computer, the modified authorization response message to the merchant.

Another embodiment of the invention is directed to a server computer that is configured to perform the above-described method.

These and other embodiments are described in further detail below.

DETAILED DESCRIPTION

Embodiments of the invention are directed to methods and systems for processing transactions using a merchant generated “pay-me” token (i.e., account identifier) to complete a transaction through a “push” type of transaction.

Typical payment transactions include a consumer providing a merchant an account identifier and the merchant “pulling” money from the consumer's account. However, these transactions can be unsecure because the consumer gives their account identifier as well as authentication credentials to the entity they wish to pay. However, embodiments of the present invention may complete a transaction using a push transaction mechanism where a merchant can provide an account identifier to a consumer and the consumer can “push” money from their account to the merchant's account associated with the merchant account identifier.

For example, in one embodiment, a consumer may desire to purchase goods or services from a merchant and may approach a merchant point-of-sale terminal to pay for the goods or services. The merchant may scan the products into a merchant computer and may generate a pay-me token (e.g., a merchant token) that may be sent to an access device. The pay-me token may be in the form of a machine readable code, for example, a QR™ code, and may comprise a merchant account identifier as well as transaction data (e.g., transaction amount, product codes, etc.). The access device may display the QR™ code to the consumer. The consumer may scan the QR™ code from the access device with their phone or other portable device. The consumer may then authenticate the transaction by providing an authentication token to the phone (e.g., by stating a requested word or statement or via other means). The phone may then submit a transaction request including the merchant token, a device identifier (e.g., phone number), and the authentication token to a payment processing network for transaction processing. The payment processing network may then determine the consumer's account using the phone number, may authenticate the consumer using the authentication token, and may transfer money from the consumer's account to the merchant account associated with the merchant account identifier. Accordingly, a transaction may be processed without the consumer's account information being transferred to the merchant or otherwise sent over a communications network.

Accordingly, push payment transactions provide better security for consumers because the consumer's account information is not passed to a wide number of entities (some of which may have malicious or fraudulent intent) and the consumer's account information is only passed within a secure payment channel. Additionally, consumers are provided with additional transaction processing options including the use of a mobile communication device. Furthermore, the push payments are more secure and convenient for merchants because the merchants do not have to store sensitive consumer account information.

Prior to discussing embodiments of the invention, it may be helpful to describe some terms that are used in this application.

A “mobile communication device” may include any suitable wireless device. For example, the mobile communication device may be a smart phone with the capability to connect to a telecommunications network. A mobile communication device may include a device identifier. For example, the device identifier may be a phone number, a digital wallet identifier, a serial number, a SIM card number or any other identifier that can identify the mobile communication device. In some embodiments, the mobile communication device can have the capability to scan a machine readable code such as a QR™ code on a display. In some embodiments, the mobile communication device can have the capability to communicate with a POS terminal using a short range communication technology such as Near Field Communication (NFC).

A “consumer” may be an individual such as a person. The terms “consumer” and “user” may be used interchangeably in this specification.

A “consumer account number” may be an account number associated with a consumer. For example, a consumer account number may be a payment account number such as a primary account number, e.g., credit, debit, loyalty or prepaid account number. The consumer account number may be issued by an issuer such as a bank. In some embodiments, a consumer account number may be associated with a device identifier (e.g., a mobile phone number of a consumer).

A “merchant token” may include any suitable information associated with a merchant. In some embodiments, a merchant token may include a merchant account identifier, for example, a financial account number associated with a merchant. In some embodiments, a merchant token may also include an expiration date along with a merchant account number. In some embodiments, a merchant token may also include transaction data, for example, a transaction amount, a timestamp, a location of the transaction, product codes, etc. In some embodiments, a merchant token may also include a merchant identifier. In some embodiments, the merchant token may be represented in the form of a machine readable code such as a QR™ code, a bar code, etc.

A “merchant account identifier” may include an identifier for an account associated with a merchant. In some embodiments, a merchant account identifier may include an account number and an expiration date. For example, the account number may be associated with a credit or deposit only bank account of the merchant. In some embodiments, the merchant bank account may be associated with an acquirer/issuer. It may also be in the form of a traditional PAN (primary account number) so that it may be routed in an ISO message in a normal credit or debit card transaction. A traditional PAN typically has sixteen characters and the first six characters form the BIN or bank identification number. However, the BIN of the PAN of a merchant account identifier would be a merchant identification number rather than a bank identification number. The merchant account identifier may be static or dynamic. In some embodiments, the merchant account identifier is dynamic. The dynamic merchant account identifier may be used as both a transaction ID to identify the particular transaction being conducted (e.g., to match the authorization of the transaction to the transaction details) as well as a way to route the authorization response to the correct merchant.

An “access device” may include a device that may be configured to interact with a consumer mobile device. In some embodiments, the access device may be any suitable device for communicating with a merchant computer or a payment processing network, and for interacting with a user computer apparatus, and/or a user mobile communication device. In some embodiments, an access device may be configured to display a machine readable code such as a QR™ code generated by another device such as a merchant computer or a backend server. An access device may generally be located in any suitable location, such as at the location of a merchant.

An access device may be in any suitable form. Some non-limiting examples of access devices include point-of-sale (POS) devices, cellular phones, PDAs, personal computers (PCs), tablet PCs, hand-held specialized readers, set-top boxes, electronic cash registers (ECRs), automated teller machines (ATMs), virtual cash registers (VCRs), kiosks, security systems, access systems, websites, and the like. An access device may use any suitable contact or contactless mode of operation to send or receive data from, or associated with, a payment device and/or a user mobile device. In some embodiments, where an access device may comprise a POS terminal, any suitable POS terminal may be used and may include a reader, a processor, and a computer-readable medium. A reader may include any suitable contact or contactless mode of operation. For example, exemplary readers can include radio frequency (RF) antennas, optical scanners, bar code readers, or magnetic stripe readers to interact with a payment device and/or mobile device.

A “merchant account” may refer to an account associated with a merchant. In some embodiments, the merchant account may be a credit only account or deposit only account. For example, the merchant account may only allow deposits into the account but may not allow withdrawals from the account. In some embodiments, the merchant account may be associated with an acquirer, for example, the acquirer may manage the merchant account.

“Transaction data” may include data related to a transaction. For example, in some embodiments, the transaction data may include one or more of a transaction amount, a timestamp (e.g., date and time) of the transaction, a location of the transaction, number of items, item details, product code (e.g., SKU numbers), etc. In some embodiments, transaction data may be determined by a merchant computer after scanning the goods or products the consumer may desire to purchase.

An “authentication token” may include any suitable information that can authenticate a consumer. In some embodiments, the authentication token may be provided by the consumer to authenticate for a transaction using a mobile communication device, e.g., to validate if the consumer is the authorized user of the mobile communication device. In some embodiments, an authentication token may include a biometric identifier associated with the consumer such as voice, fingerprints, iris, face, signature, hand geometry, etc. In some embodiments, the consumer may register one or more authentication tokens with a server computer that may store these authentication tokens to authenticate the consumer for future transactions.

A “transaction request message” may include a message for a transaction request. In some embodiments, a transaction request message may be provided by a mobile communication device to a server computer to process a transaction request. In some embodiments, a transaction request message may include a merchant token, a mobile communication device identifier or consumer account number (which may be a real account number or a pseudo PAN, which is a PAN that is linked to the real account number but is not the real account number), and an authentication token. For example, a merchant token may include a merchant account identifier, a mobile communication device identifier may include a phone number and an authentication token may include a voice input of a consumer initiating the transaction request.

An “authorization request message” may be an electronic message that is sent to a payment processing network and/or an issuer of a payment card to request authorization for a transaction. An authorization request message according to some embodiments may comply with ISO 8583, which is a standard for systems that exchange electronic transaction information associated with a payment made by a consumer using a payment device or payment account. The authorization request message may include an issuer account identifier that may be associated with a payment device or payment account. An authorization request message may also comprise additional data elements corresponding to “identification information” including, by way of example only: a service code, a CVV (card verification value), a dCVV (dynamic card verification value), an expiration date, etc. An authorization request message may also comprise “transaction information,” such as any information associated with a current transaction, such as the transaction amount, merchant identifier, merchant location, etc., as well as any other information that may be utilized in determining whether to identify and/or authorize a transaction.

A “server computer” can be a powerful computer or a cluster of computers. For example, the server computer can be a large mainframe, a minicomputer cluster, or a group of servers functioning as a unit. In one example, the server computer may be a database server coupled to a Web server.

An “authorization response message” may be an electronic message reply to an authorization request message generated by an issuing financial institution or a payment processing network. The authorization response message may include, by way of example only, one or more of the following status indicators: Approval—transaction was approved; Decline—transaction was not approved; or Call Center—response pending more information, merchant must call the toll-free authorization phone number. The authorization response message may also include an authorization code, which may be a code that a credit card issuing bank returns in response to an authorization request message in an electronic message (either directly or through the payment processing network) to the merchant's access device (e.g. POS equipment) that indicates approval of the transaction. The code may serve as proof of authorization. As noted above, in some embodiments, a payment processing network may generate or forward the authorization response message to the merchant.

FIG. 1 shows a transaction processing system in one embodiment of the present invention.

A transaction processing system 100 may include a consumer 102, a mobile communication device 104, an access device 106, a merchant computer 108, an acquirer computer 110, a payment processing network computer 112, an issuer computer 114 and a telecommunications network 116.

The consumer 102 may operate the mobile communication device 104 to initiate a transaction at the access device 106. The access device 106 may be associated with or operated by the merchant computer 108. The mobile communication device 104 may be configured to communicate with the payment processing network computer 112 through the telecommunications network 116. The telecommunications network 116 may include any suitable network that is capable of transmitting information between two entities and may be capable of using any suitable communications protocol (e.g., cellular network, TCP/IP, etc.)

In some embodiments of the invention, the consumer 102 may register one or more authentication tokens in an authentication payment program associated with a payment processing network. For example, the consumer 102 may provide one or more biometric samples such as voice, fingerprints, iris, face, signature, hand geometry, etc. to the payment processing network computer 112 by operating the mobile communication device 104. For example, the mobile communication device 104 may be a smart phone with the capability to connect to the telecommunications network 116. The mobile communication device 104 can comprise one or more input interfaces (e.g., a microphone, camera, touch screen, etc.) to allow the consumer 102 to input information for enrolling the authentication tokens.

The mobile communication device 104 may be a mobile phone, a tablet, a notebook, a PDA, a laptop, a netbook, a key fob, etc. In some embodiments, a device identifier may be associated with the mobile communication device 104. For example, the device identifier may be a phone number, a digital wallet identifier, a serial number, a SIM card number or any other identifier that can identify the mobile communication device 104. The mobile communication device 104 may be capable of reading a machine readable code such as a QR™ code displayed by the access device 106. For example, the consumer 102 may scan a QR™ code associated with a transaction displayed on a display of the access device 106 using a camera or a scanning device on the mobile communication device 104. The QR™ code may include a merchant token, e.g., a pay-me token generated by the merchant computer 108. The mobile communication device 104 may also allow the consumer 102 to provide an authentication token for authentication. The mobile communication device 104 may also be capable of generating a transaction request message including the merchant token, the authentication token provided by the consumer 102 and the device identifier. FIG. 6 illustrates an exemplary QR™ code 602 captured by the mobile device 104 from the access device 106. The QR™ code 602 may include a merchant token 604.

Referring back to FIG. 1, the access device 106 may be an access point to a transaction processing system that comprises the payment processing network computer 112 and the issuer computer 114. In some embodiments, the access device 106 may be configured to display a token generated by the merchant computer 108 in a format that may be read by the mobile communication device 104 including machine readable codes such as a QR™ code, a bar code, or any other information transfer mechanism. For example, the merchant token may include a merchant account identifier (e.g., a bank account number) associated with a merchant account that may be used for a transaction and transaction data associated with the transaction. In some embodiments, the merchant account associated with the merchant account identifier may be a credit only or a deposit only account. For example, the merchant account may not allow withdrawals from the account and may only allow deposits into the account. As shown in FIG. 6, the access device 106 displays the QR™ code 602 that includes the merchant token 604 on a display 606.

Referring back to FIG. 1, the merchant computer 108 may be configured to generate a merchant token. In some embodiments, the merchant token may comprise a merchant account identifier and transaction data. For example, the merchant account identifier may correspond to a merchant bank account associated with the acquirer computer 110. In some embodiments, the acquirer computer 110 and the issuer computer 114 may be associated with the same financial entity, e.g., a bank. The merchant computer 108 may be configured to communicate with the acquirer computer 110 via any suitable communication network such as TCP/IP. The merchant computer 108 may provide the merchant token to the access device 106 that may be coupled to the merchant computer 108. In some embodiments, the merchant token may be in the form of a machine readable code such as a QR™ code or a bar code. In some embodiments, the merchant computer 108 and the access device 106 may be integrated as a POS device that can generate a merchant token and display the merchant token on a display screen of the POS device as a machine readable code. In some embodiments, a merchant token may be referred to as a “pay-me” token.

The merchant generated “pay-me” token may include both a static or dynamic merchant account identifier as well as dynamic transaction information. The static merchant or dynamic merchant account identifier may identify a merchant “pay-me” account at an issuer that may be used for credit transactions. For example, the merchant account identifier may be used to identify or be associated with a merchant credit account at an issuer that can only be used to transfer money to the account. Generally, credit only merchant accounts do not have security risks that may be associated with the debit accounts (which allow debit transactions) and may be published widely. Accordingly, the merchant account identifier provided by the merchant token is not secure information that must be protected from malicious third parties (as money can only be transferred to the account).

The acquirer computer 110 may be associated with an acquirer. The acquirer may issue and manage a financial account for the merchant, e.g. associated with a merchant account identifier. The acquirer computer 110 may be communicatively coupled to the merchant computer 108 and the payment processing network computer 112. In some embodiments, the acquirer computer 110 may receive an authorization response message from the payment processing network computer 112 for a transaction and may forward it to the merchant computer 108 to confirm processing of the transaction.

The payment processing network computer 112 may be associated with a payment processing network. A payment processing network may include data processing subsystems, networks, and operations used to support and deliver authorization services, exception file services, and clearing and settlement services. An exemplary payment processing network may include VisaNet™. Payment processing networks such as VisaNet™ are able to process credit card transactions, debit card transactions, and other types of commercial transactions. VisaNet™, in particular includes a Visa Integrated Payments (VIP) system which processes authorization requests and a Base II system which performs clearing and settlement services. Furthermore, the payment processing network may use any suitable wired or wireless telecommunications network, including the Internet.

In some embodiments, the payment processing network computer 112 may store authentication tokens for a plurality of consumers in an authentication token database (not shown), e.g. via a registration process. For example, one or more authentication tokens for each consumer may be stored in the authentication token database based on a device identifier and/or an account identifier (e.g., a primary account number (PAN)) associated with the consumer during an enrollment or registration process. In some embodiments, the payment processing network computer 112 may determine a consumer account from a consumer account database (not shown) based on the device identifier. In some embodiments, the payment processing network computer 112 may determine a merchant account to which the money may be pushed from the consumer account based on a merchant account identifier received in a transaction request message.

The issuer computer 114 may be associated with an issuer. An issuer can be any bank that can issue and maintain a financial account for a user, e.g., consumer 102. Some systems can perform both issuer and acquirer functions. When a transaction involves a payment account associated with the issuer computer 114, the issuer computer 114 may verify the account and respond with an authorization response message to the acquirer computer 110 via the payment processing network 112 that may forward it to the access device 106. The authorization response message may include an identifier to describe whether the transaction was approved or declined. The access device 106 may communicate to the consumer 102 about the outcome of the authorization based on the authorization response message.

An exemplary flow for completing a payment transaction, according to embodiments of the present invention is discussed with reference to FIG. 1. Before the transaction begins, the consumer 102 may select goods or services to purchase at a merchant location.

At step 1, the merchant may scan the goods or otherwise determine the subject of a transaction. After finalizing the products for the transaction, the merchant computer 108 may generate a pay-me token (or merchant token). In some embodiments, the machine readable code may include a merchant account identifier that has also been generated by the merchant, a transaction amount, and any other transaction details (e.g., a timestamp, number of items, line item details, product codes, etc.). The merchant account identifier may be static or dynamic in nature, and may also be in the form of a conventional credit or debit card PAN (primary account number). In some embodiments, if it is dynamic, then many dynamic merchant account identifiers could map directly to one deposit only real merchant account identifier for an account at the acquirer. A lookup table or an algorithm could be used to provide this mapping.

The merchant computer 108 may provide the merchant token to the access device 106 to interact with the consumer's mobile communication device 104. For example, the access device 106 may display the machine readable code that includes the merchant token. In some embodiments, the access device 106 may be capable of sending the merchant token through short-range communication technology (e.g., NFC elements, etc.), or the merchant token may be provided to the mobile communication device 104 through any other suitable method.

In other embodiments, the merchant computer 108 is not necessary and the access device 106 may generate the merchant token instead of the merchant computer 108.

Further, in some embodiments, if the merchant account identifier is generated on a per transaction or otherwise periodic basis, the merchant account identifier may also be transmitted to the acquirer computer 110 so that the acquirer is aware that this merchant account identifier has been created by the merchant. In this way, the acquirer will recognize any subsequently transmitted authorization response message coming from the payment processing network computer 112, even though a corresponding authorization request message comprising the merchant account identifier was never created or transmitted.

At step 2, the consumer 102 may read or receive the merchant token at their mobile communication device 104 from the access device 106. For example, the consumer 102 may scan the machine readable code, or other displayed object with their mobile communication device 104 to obtain the merchant token from the access device 106. Alternatively, the consumer 102 may wave their mobile communication device 104 close to the access device 106 to receive the merchant token via a short range communication technology such as NFC. Any other suitable form of communication between the mobile communication device 104 and the access device 106 may be used for transfer of the merchant token to the mobile communication device 104.

At step 3, the mobile communication device 104 may decode the machine readable code received from the access device 106 and display the transaction details to the consumer 102. The mobile communication device 104 may prompt the consumer 102 for authorization to submit the transaction for processing. For example, the mobile communication device 104 may prompt the consumer 102 to provide an authentication token. The consumer 102 may then provide authorization by providing an authentication token. The authentication token may be in the form of a biometric identifier such as voice, fingerprint, iris, facial expression, hand geometry, etc., a passcode, a password, a personal identification number (PIN), etc.

In some embodiments, the consumer 102 can authorize the transaction by stating a requested word or statement (e.g., a password, a PIN or a pre-determined word or statement) using their voice. In some embodiments, the mobile communication device 104 may prompt the consumer 102 to read a word, an alphanumeric string or a statement displayed by the mobile communication device 104. For example, the consumer 102 may speak into the mobile communication device 104, and the mobile communication device 104 can transmit a sample of the user's voice or a digital artifact of the user's voice to the payment processing network computer 112. The voice sample provided by the consumer 102 may be used for signing or approving the transaction. This may help ensure that the mobile communication device 104 was not stolen or that the account is not being used by a malicious third party. Voice authentication technology or speaker verification technology may be used to validate that the consumer 102 is the authorized user to initiate the transaction using the mobile communication device 104. Furthermore, the voice recording could be saved as a proof that the consumer 102 approved or initiated the transaction. Alternatively, or additionally, the consumer 102 may provide a password, a passcode or a PIN using a keypad or a touch screen interface of the mobile communication device 104.

At step 4, a transaction request message may be generated by the mobile communication device 104 and may be sent to the payment processing network computer 112 through the telecommunications network 116. The mobile communication device 104 may generate a transaction request message comprising the merchant token, a device identifier or consumer primary account number, and an authentication token. In some embodiments, the device identifier and/or the authentication token need not be present in the transaction request message. For example, the authentication token may be provided to the payment processing network computer 112 at a later time or not at all. Once the transaction request message is generated, the mobile communication device 104 may then send the transaction request message to the payment processing network computer 112 for processing.

In other embodiments, the transaction request message can be sent to another server computer such as the acquirer computer or the issuer computer, and similar processing can be performed.

In some embodiments, before sending the transaction request message, the consumer 102 may further be prompted for confirmation that they would like to initiate a transaction. For example, the consumer 102 can press a submit button or otherwise interact with the mobile communication device 104 to indicate that the transaction details are correct and the transaction can be initiated.

The payment processing network computer 112 may receive the transaction request message from the mobile communication device 104 and may begin processing the transaction. In some embodiments, the payment processing network computer 112 may verify that the authentication token is associated with the device identifier. For example, based on the device identifier, the payment processing network computer 112 may retrieve one or more authentication samples stored in an authentication database for comparison. In some embodiments, authentication of the consumer 102 can be based on both a match score indicating how closely the captured voice sample matches to previously stored voice samples of the consumer 102 (called “a model of the user's voice”), and/or a pass or fail response indicating whether the voice sample is an accurate reproduction of the word string.

The consumer's voice sample can be authenticated in any suitable manner. In an embodiment, the systems and methods can use voice biometric techniques, specifically a variation of a conventional prompted text independent speaker verification system. Certain embodiments allow the use of a captured voice sample attempting to reproduce a word string having a random element to authenticate the consumer 102.

After determining that the consumer 102 is associated with the mobile communication device 104 that is enrolled in the system, the payment processing network computer 112 may determine an issuer and a consumer account associated with the device identifier if the device identifier is present in the transaction request message and the consumer account identifier is not in the transaction request message. The payment processing network computer 112 may determine a merchant pay-me account associated with the merchant account identifier and may start the process of transferring funds equal to the transaction amount to the merchant pay-me account from the consumer account.

At step 5, the payment processing network computer 112 may generate and send an authorization request message to the issuer computer 114 operated by the issuer of the consumer's account and may obtain authorization for the transaction. The authorization request message may contain the consumer's account identifier and the amount of the transaction.

At step 6, the issuer computer 114 may determine whether the transaction should be authorized and may generate an authorization response message that can comprise an indication of a transaction decision. The payment processing network computer 112 then can receive an authorization response message comprising the consumer account identifier from the issuer computer 114.

At step 7, the payment processing network computer 112 may substitute the merchant account identifier in the authorization response message to form a modified authorization response message. The modified authorization response message (or other confirmation message) may be sent to the merchant computer 108 and the access device 106, and optionally the mobile communication device 104 to inform the parties as to whether the transaction is approved or declined. The authorization response message may include the merchant identifier so that the authorization response message is routed to the proper merchant. Data in the authorization response message (e.g., a transaction ID, a timestamp, a dynamic merchant account identifier, etc.) may be used by the merchant to match the response to the transaction data for the transaction.

At the end of the day, the transaction can be cleared and settled between the acquirer computer 110 and the issuer computer 114 by the payment processing network 112. Funds may be transferred from the issuer computer to the merchant computer 108 during the settlement process. In a clearing process, clearing messages are sent between the acquirer computer 110, the payment processing network 12, and the issuer computer 114 to facilitate settlement. In some cases, AFT (account funding transaction) or OCT (original credit transaction) messages may be used to debit and credit the appropriate accounts.

FIG. 2 illustrates some components of an access device according to one embodiment of the invention.

The access device 106 may include a processor 200 coupled to a network interface 202, a memory 204, a reader 206, input elements 208, output devices 210 and a computer readable medium 212. The access device 106 may be an independent device, coupled to the merchant computer 108 or may be part of a POS terminal.

The merchant token may include a merchant account identifier and transaction data.

The authentication token module 402C may comprise code that may cause the processor 400 in the mobile communication device 104 to prompt the consumer 102 to provide an authentication token to authenticate for the transaction. For example, after the consumer 102 has captured the merchant consumable token from the access device 106, a web page may prompt the consumer 102 to provide an authentication token before the transaction can be initiated. FIG. 7B shows an exemplary screen shot of the mobile communication device 104 for initiating a transaction.

As shown in FIG. 7B, a webpage 704 may prompt the consumer 102 to provide an authentication token (706). In some embodiments, the consumer 102 may be prompted to provide an authentication token to authenticate themselves before they can submit the transaction (708). For example, as discussed previously, the authentication token may be in the form of a biometric sample such as voice, fingerprint, iris, facial expression, hand geometry, etc., a passcode, a password, a personal identification number (PIN), etc. After providing the authentication token, the consumer 102 may select the submit transaction button to initiate the transaction. In some embodiments, transaction details (not shown) may be presented to the consumer 102 for the consumer 102 to verify the transaction details before selecting the submit transaction button.

Referring back to FIG. 4B, after the consumer 102 provides the authentication token to initiate the transaction, a transaction request message may be generated by the transaction request generator module 402D. In some embodiments, the transaction request message may include a merchant token (e.g., obtained by the merchant token receiver module 402B), an authentication token (e.g., obtained by the authentication token module 402C) and a device identifier of the mobile communication device 104. The transaction request message may be transmitted by the mobile communication device 104 to the payment processing network computer 112 via the telecommunications network 116. The mobile communication device 104 may receive a confirmation message (e.g., an SMS message or e-mail message) that the payment has been processed or after the transaction has been authorized.

FIG. 5 illustrates some components of a server computer 500 in one embodiment of the invention. The server computer 500 may be associated with the payment processing network computer 112, the acquirer computer 110, the issuer computer 114 or any other suitable entity.

The server computer 500 may include a processor 502 coupled to a network interface 504, an authentication token database 506, a merchant account database 508, a consumer account database 510 and a computer readable medium 512. The computer readable medium 512 may comprise code executable by the processor 502 for implementing methods using embodiments of the invention. The computer readable medium 512 may be in the form of a memory that stores data and could be internal to server computer 500 or hosted remotely.

The network interface 504 may be configured to enable the server computer 500 communicate with other entities (e.g., acquirer computer 110, issuer computer 114, mobile communication device 104) using one or more communications networks.

The authentication token database 506 may be configured to store authentication tokens for consumers. For example, for consumer 102, the authentication token database 506 may store one or more of voice, fingerprint, iris, facial expression, hand geometry, etc. sample, a passcode, a password, a personal identification number (PIN), etc. In some embodiments, the authentication tokens may be stored in the authentication token database 506 at the time of the user registration. In some embodiments, the authentication tokens in the authentication token database 506 may be linked to the respective device identifiers and/or consumer account identifiers.

The merchant account database 508 may be configured to store information associated with a plurality of merchant accounts such as merchant account numbers, expiration dates, account types (e.g., deposit only, regular checking or savings account, etc.), merchant identifiers, merchant names, merchant addresses, etc. Each merchant account in the merchant account database 508 may be associated with a respective merchant account identifier.

The consumer account database 510 may be configured to store information associated with a plurality of consumer accounts such as consumer account numbers, expiration dates, consumer names, consumer phone numbers, consumer addresses, etc. Each consumer account in the consumer account database 510 may be associated with a respective device identifier.

In some embodiments, the authentication token database 506 and the consumer account database 510 may be linked and may be accessed using a device identifier to retrieve a consumer account and stored authentication tokens based on the device identifier.

The registration module 512A may include code that can cause the processor 502 in the server computer 500 to register one or more consumers. In some embodiments, the registration module 512A may allow the consumer 102 to register one or more authentication tokens that may be used to authenticate a transaction conducted by the consumer 102. For example, as discussed with reference to FIG. 7A, the consumer 102 may be directed to the webpage 702 to register the authentication token. The registered authentication tokens may be stored in the authentication token database 506.

The transaction request decoder module 512B and an associated processor may be configured to receive the transaction request message transmitted by the mobile communication device 104 and to decode the transaction request message. The transaction request message may include a merchant token, a device identifier of the mobile communication device 104 and an authentication token. The merchant token may include a merchant account identifier and transaction data (e.g., a transaction amount and other transaction related information). For example, as discussed with reference to FIG. 7B, a transaction request message may be generated by the mobile communication device when the consumer 102 provides an authentication token and submits a transaction initiation request using the merchant token.

The merchant account identifier module 512C may be configured to identify a merchant account based on the merchant account identifier provided in the transaction request message. For example, the merchant account identifier module 512B may retrieve information associated with the merchant account from the merchant account database 508. In some embodiments, the merchant account may be a credit only merchant account from which money cannot be withdrawn.

The consumer account identifier module 512D may comprise code executable by the processor 502 in the server computer 500 so that the server computer 500 can identify a consumer account and an issuer based on the device identifier obtained from the transaction request message. For example, the consumer account identifier module 512D may determine information associated with the consumer account based on the device identifier obtained from the transaction request message.

The authentication module 512E may comprise code, executable by the processor 502, to cause the server computer 500 to authenticate the consumer 102 by comparing the authentication token provided by the consumer 102 with the authentication token stored in the authentication token database 506. In some embodiments, the authentication module 512E may retrieve one or more authentication tokens from the authentication token database 506 based on the device identifier obtained from the transaction request message to verify that the authentication token provided by the consumer 102 is associated with the device identifier. For example, in some embodiments, authentication of the consumer 102 can be based on both a match score indicating how closely the captured voice samples match to previously stored voice samples of the consumer 102 (called “a model of the user's voice”) in the authentication token database 506, and/or a pass or fail response indicating whether the voice sample is an accurate reproduction of the word string.

The consumer's voice sample can be authenticated in any suitable manner. In one embodiment, the systems and methods can use voice biometric techniques, specifically a variation of a conventional prompted text independent speaker verification system. Certain embodiments can allow the use of a captured voice sample attempting to reproduce a word string having a random element to authenticate the consumer 102.

The authorization and settlement module 512F may comprise code, executable by the processor 502, to facilitate authorization and settlement processes. It can cause the server computer 500 to transfer money from the consumer account identified using the device identifier to the merchant account identified using the merchant account identifier for the amount equal to the transaction amount included in the merchant token. In some embodiments, a confirmation message that the payment has been processed may be sent to the mobile communication device 104. Accordingly, a transaction may be processed without the consumer's account information being transferred to the merchant or otherwise sent over a communications network. The authorization and settlement module 512F may also include code that can cause the processor 502 in the server computer 500 to generate an authorization request message to get authorization from the issuer associated with the consumer account. The authorization request message may be transmitted to the issuer computer 114 using a suitable communication medium. The authorization and settlement module 512F may also comprise code that can cause the processor 502 to receive an authorization response message from the issuer computer 114 and to forward the authorization response message to the merchant computer 108 via the acquirer computer 110 and also to the mobile communication device 104 indicating whether the transaction was approved or declined. At the end of the day, the transaction may be cleared and settled between the acquirer computer 110 and the issuer computer 114 by the authorization and settlement module 512F.

As noted above, in embodiments of the invention, push payment transactions may provide better security for consumers because the consumer's account information is not passed to a wide number of entities (some of which may have malicious or fraudulent intent) and the consumer's account information is only passed within a secure payment channel. Additionally, consumers are provided with additional transaction processing options including the use of a mobile communication device. Furthermore, the push payments are more secure and convenient for merchants because the merchants do not have to store sensitive consumer account information.

It is noted that other embodiments are also possible. For example, embodiments of the invention could be operated by an issuer, acquirer, or any other entity within a transaction processing system.

Furthermore, although the example above focuses on a retail purchase transaction, embodiments of the invention may be implemented for e-commerce transactions as well. In such transactions, the user's computer may be used as the access device and a merchant could include a bar code or QR™ code on a website so that a user does not have to key in their account number, password, etc. The e-commerce embodiment further provides convenience for a consumer (i.e., user) as they do not have to input their financial information into a website checkout procedure.
