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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, system, and device for generating, storing, using, and validating NFC tags and data","description":"A smart tag and methods of interacting with and authenticating interactions with the same are provided.
