Abstract
A smart tag and methods of interacting with and authenticating interactions with the same are provided. The smart tag is enabled to generate a Tag Authentication Cryptogram (TAC) and include the TAC in response to a read request. Accordingly, each response generated by the smart tag will include a different TAC. It follows that interactions between the smart tag and a reading device can be authenticated as unique interactions if the TAC is validated as a unique and correct TAC.
