Reporting on authentication of RFID tags for indicating legitimacy of their associated items
摘要:
RFID readers, computers, and methods are provided for reporting on the authentication of one or more RFID tags associated with a proffered item, while requiring special permissions be cleared before reporting. In some embodiments, a question is input about whether a Declared Password (DP) is regarded as proper for an Item Identifier (II), both of which have been input from the tags. An answer is generated for the question from the reference database, and transmitted to the user. The answer does not reveal an Actual Code that is indeed regarded as proper, unless the user first demonstrates they already know it. Beyond the authentication of the tag, the answer can further indicate the legitimacy of the proffered item, for a supply chain, at a Customs Office, etc.
