While RFID technology has greatly facilitated visible supply chain management, designing a secure and efficient RFID-tagged supply chain system is still a challenge. To achieve high security and efficiency at the same time, we categorise RFID-tagged supply chain environments in two security levels and design an RFID-tagged supply chain system accordingly. In the relatively secure environment, our system is set to the weak security mode, and the tagged products can be processed in a highly efficient manner. While in the less secure environment, our system is tuned into the strong security mode so as to maintain a high level of security with its efficiency lower than that in the weak security mode. A set of RFID protocols are designed to enable the duel security modes.
