NFC terminal devices and corresponding integrated circuit cards (ICCs) use NFC Type 4 tags as a protocol interface for complex or encrypted communication protocols that are not natively supported by the NFC terminal devices. A smartphone acting as an NFC terminal may block applications and/or protocols other than NFC data exchange formatted (NDEF) messages. An ICC applet supporting an advanced function uses designated memory locations for the transfer of commands normally supported at an application level. Both the terminal side and the ICC applet may check the designated memory locations for updated data in the absence of protocol-level message controls.

Type 4 NFC tags as protocol interface

A method performed by at least a user device comprising an interaction application and a biometric application is disclosed. The method comprises receiving from an access device, a message comprising interaction details. The user device may perform a biometric verification of the user operating the user device. The method may then include, if the biometric application has a biometric verification result, the interaction application receives the biometric verification result from the biometric application and continues processing the message. Or if the biometric application does not have the biometric verification result, then the interaction application either waits for the biometric verification result from the biometric application or continues processing the message without the biometric verification result.

Embodiments are described that are directed to optimizing the provisioning of payment account credentials to mobile devices utilizing mobile wallets. In some embodiments, one of multiple provisioning schemes may be selectively chosen for payment account credential provisioning based upon a determined risk involved with a particular provisioning request. A low risk provisioning request leads to an immediate provisioning of a payment credential, whereas a provisioning request of high risk results in the provisioning request being denied. In some embodiments, medium risk provisioning requests will cause an additional user authentication to be performed before the payment account provisioning is finalized. The additional user authentication may occur using a separate communication channel than the channel in which the provisioning request was received.

Methods and systems for provisioning mobile devices with payment credentials

Secure remote payment transaction processing including consumer authentication

A system, apparatus, and method for processing payment transactions that are conducted using a mobile device that includes a contactless element, such as an integrated circuit chip. The invention enables the updating, correction or synchronization of transaction data maintained by an Issuer with that stored on the device. This is accomplished by using a wireless (cellular) network as a data communication channel for data provided by an Issuer to the mobile device, and is particularly advantageous in circumstances in which the contactless element is not presently capable of communication with a device reader or point of sale terminal that uses a near field communications mechanism. Data transferred between the mobile device and Issuer may be encrypted and decrypted to provide additional security and protect the data from being accessed by other users or applications. If encryption keys are used for the encryption and decryption processes, they may be distributed by a key distribution server or other suitable entity to a mobile gateway which participates in the data encryption and decryption operations.
