RFID TAG DEVICE AND METHOD FOR OPERATING THE SAME

摘要

An RFID tag device and an operation method thereof are provided to perform a function by designing the RFID tag device with a digital logic for performing only the required function such as issuance, authentication, and usage. An RF interface(11) extracts a command from a received RF signal. A storing part(14) stores ID information and a key value for encryption. An encryptor(13) encrypts the ID information by using the key value. A controller(12) reads the ID information and the key value from the storing part, and outputs the ID information and the key value to the encryptor by the command received from the RF interface, and receives and outputs the encrypted ID information through the RF interface. The storing part is a non-volatile memory storing the information even if power is not supplied. The controller includes an RF interface linker(121), an encryptor linker(122), a storing part controller(123), and a command processor(124) implemented as the digital logic.
