Abstract:
A payment device—payment device reader combination obtains issuer token data that was generated by an issuer entity from: input data, and an issuer application cryptogram based on the input data and a session key. The issuer token data is disassembled by the payment device—payment device reader combination to obtain the input data and the issuer application cryptogram, and the payment device—payment device reader combination computes a payment device application cryptogram based on the input data and the session key. This is compared, by the payment device—payment device reader combination, to the issuer application cryptogram. If the payment device application cryptogram matches the issuer application cryptogram, at least one action is allowed to take place on the payment device.
