Abstract: Systems and methods for verifying users in connection with transactions are disclosed. One exemplary method includes, based on the payment card device being presented at a terminal, initiating, by a security chip of the payment card device, a timer and then based on the timer being unexpired, capturing, by a biometric sensor of the payment card device, a biometric image and verifying, by the security chip, the captured biometric image against reference biometric data stored the payment card device. The method also includes, based on the captured biometric image being verified, cooperating, by the security chip, with the terminal, to initiate a transaction to an account using a first account number specific to a biometric application of the payment card device.

Abstract: Systems and methods for verifying users in connection with transactions are disclosed. One exemplary method includes, in response to a payment device being inserted at a terminal, initiating, by a security chip of the payment device, a timer and capturing, by a biometric sensor of the payment device, a fingerprint while the timer is unexpired. The method also includes verifying, by the security chip, the captured fingerprint against reference fingerprint data stored in memory in the payment device and, in response to the captured fingerprint being verified, while the timer is unexpired, initiating, by the security chip, with the terminal, a transaction to an account using an account number specific to a biometric application of the payment device. An issuer can recognize verification of a user associated with the fingerprint based on the account number in an authorization request, instead of a different account number for the account.

Abstract: Systems and methods for verifying users in connection with transactions using payment devices are disclosed. One exemplary method generally includes receiving a select command for an AID associated with a payment application from a terminal and, in response, initiating by a security chip of a payment device, a timer after power-up of the security chip by the terminal. The method also includes capturing a biometric of a user, at a biometric sensor, according to the payment application, and verifying, by the security chip, the captured biometric based on reference biometric data. The method further includes, when the timer is unexpired and the captured biometric is verified, appending a first value to a CVR and returning a first AFL to the terminal, and when the timer is expired, appending a different value to the CVR and returning a different AFL to the terminal.

Abstract: Systems and methods for verifying users in connection with transactions using payment devices, by which benefits are distributed, are disclosed. One exemplary method generally includes initiating a timer after power-up of a security chip by a terminal, capturing a biometric of a user, at a biometric sensor associated with the security chip, and comparing, by the security chip, the captured biometric to a reference biometric. When the time is unexpired, and the captured biometric matches the reference biometric, the method includes launching a biometric application, whereby the terminal appends a first account number to an authorization request for a transaction to the payment account, when the timer is expired, the method includes launching a standard payment application, whereby the terminal includes a second account number in an authorization request for a transaction to the payment account, the first account number is different than the second account number.

Abstract: A Chip Authentication Program based on 3-D Secure protocols is provided for authenticating customers' on-line transactions. An issuer, who may be a payment card issuer, operates Access Control and Authentication Request Servers for authenticating transactions by individual customers who are identified by their personal EMV-complaint smart cards. An authentication token is generated at the point of interaction (POI) for each transaction based on information from the customer's smart card and transaction specific information sent directly by the issuer to populate a web page at the POI. Authentication tokens generated at the POI are evaluated by the Authentication Request Server to authenticate individual customer and/or card presence at the transaction POI. Authentication values are transported on-line in designated Universal Cardholder Authentication Fields consistent with 3-D Secure protocols.

Abstract: The present invention reduces the time required to apply an update package for generating a new image from an original image within a non-volatile memory device by effectively reducing the number of flash blocks requiring modification by use of whatever free space is available at the end of the image as required. A set of software development guidelines and an improved firmware development tool chain (i.e. compiler, linker, etc.) are utilized to produce new firmware for the client device. A firmware programmer follows or applies this set of guidelines when developing new features and fixes for distribution via a new firmware image. The improved firmware development tool chain executes on a collection of function blocks, available from the development of the original image, used to create new firmware source code, which when complied and linked yields a new image, prior to the delta or differencing processing.

Abstract: Methods and apparatus for operating a transaction terminal. In an embodiment, a method includes receiving, by a proximity reader processor via a first channel, an activation signal from a payment terminal processor indicating initiation of a payment transaction with a proximity payment device. The proximity processor then executes a first process having a first queue that causes transmission of first instructions to a second process comprising a second queue, and then the second process is executed to run concurrently with the first process, wherein the second process causes the proximity processor to transmit application activation instructions via a reader interface and a second channel to the proximity payment device. The proximity processor terminates the second process when the application activation is completed without error.

Abstract: Methods, systems and apparatus are provided including a proximity payment device reader which includes a reader control program. A first process is executed upon receipt of an activation signal indicating the initiation of a transaction involving a proximity payment device with the reader, the first process causing at least a first signal to be transmitted to a second process, the second process causing the transmission of at least a second signal to the proximity payment device through a transceiver. In some embodiments, the processes may be executed to compare application data received from the payment device to data stored in a transaction log to determine if the proximity payment device was involved in an interrupted transaction. If the proximity payment device was involved in an interrupted transaction a signal is transmitted to the proximity payment device to attempt to retry the interrupted transaction.
