Abstract
An RFID tag including a transmitting/receiving unit, a memory and a control unit. A first identification code, a second identification code, a password, and a set of data are stored in the memory. If the set of data is under protection, the set of data is accessible only when a verification procedure corresponding to the password is successfully performed. If the transmitting/receiving unit receives a request for accessing the second identification code, the control unit shall check whether the request includes the first identification code. As long as the checking result of the control unit is yes, even if the set of data is under protection and the verification procedure fails or the verification procedure is not successfully performed, the control unit shall still transmit the second identification code via the transmitting/receiving unit.
