Methods, systems, and machine-readable media are disclosed for handling information related to a transaction conducted with a presentation instrument at a POS device. Extended application IDs and dynamic cryptograms are used for the transaction. According to one embodiment, a method of processing a financial transaction for an account having a primary account number (PAN) can comprise detecting initiation of the transaction with the presentation instrument, and providing from the presentation instrument to the POS device a list of one or more applications IDs. Each application ID identifies an application that can be used to communicate data concerning the transaction between the presentation instrument and the POS device. The POS device selects one of the application IDs and returns it to the presentation instrument. Under the control of the selected application, the presentation instrument generates a Dynamic Transaction Cryptogram (DTC) and a dynamic PAN that are each valid for only a single transaction.

Processing transactions with an extended application ID and dynamic cryptograms

Devices and systems for performing contactless payments. The devices are configured such that account issuers have increased flexibility, and such that the systems and methods are extensible to encompass new technologies.

Mobile device contactless payments

Methods, systems, and machine-readable media are disclosed for handling information related to a financial transaction including utilizing dynamic cryptograms. According to one embodiment, a method of processing a financial transaction related to a financial account can comprise detecting initiation of the transaction with a device used as a presentation instrument in the transaction. A Dynamic Transaction Cryptogram (DTC) and a dynamic PAN can be generated at the device. The DTC can be used to authenticate the transaction and the dynamic PAN can comprise an encrypted form of a real PAN of the financial account that is valid for a single transaction. The DTC and the dynamic PAN can be provided by the device for use in the transaction.
