ABSTRACT:
An RFID tag access authentication system including a data processing terminal, a memory medium and a RFID tag. The data processing terminal generates a request signal for requesting a first key data, and transmits the request signal to the memory medium. The system transmits an inputted first identification data and the first key data received from the memory medium to the RFID tag. The system accesses the RFID tag in response to receiving of an access authentication data from the RFID tag. The RFID tag stores a second identification data and a second key data corresponding to the second identification data. The system compares a first set of the first identification data and the first key data with a second set of the second identification data and the second key data. Then, the system generates the access authentication data when the first set agrees with the second set.
