Abstract
A smart tag and methods of interacting with and authenticating interactions with the same are provided. The smart tag (308) is enabled to generate a Tag Authentication Cryptogram (TAC) and include the TAC in a data signature transmitted (S305) to a reading device (304). The data signature can be forwarded by the reading device (304) to an authentication service (340) that will issue a valid signature certificate (S309) if the TAC is determined to be unique and correct. Upon receiving the valid signature certificate, the reading device (304) can validate other data read from the smart tag (308) based on the increased trust relationship between the smart tag (308) and reading device (304).
