Abstract

Methods, devices, and systems are described for sending and receiving messages between a terminal reader and a payment device, such as a credit card. A dynamic signature is calculated on the payment device from an application transaction counter, a terminal unpredictable number, and a transaction amount, and it is sent with an application file locator (AFL) to the reader. The reader then sends a read record command to the payment device to get records associated with the AFL, among other normal processing. While the normal processing is occurring for the transaction, the dynamic signature can be recalculated and compared with that from the payment device in order to assure that nothing has surreptitiously changed the values in the messages.
