Problems solved by technology
Although the radio frequency identification tag itself can set an authentication mechanism such as a password to prevent unauthorized radio frequency reading devices from reading the data pre-stored in the internal memory of the tag, however, when the unauthorized radio frequency reading device knows the existence of the authentication mechanism, It can continue to try to crack the authentication mechanism, and as long as there is enough time, the current imperfect RFID tag authentication mechanism is likely to be cracked

The invention discloses a radio frequency identification tag and an operation method thereof which can lower the risk that data of the radio frequency identification tag is stolen by an illegal radio frequency reading device. The operating method for the radio frequency identification tag comprises the following steps: firstly, receiving a reading command; secondly, generating a mode parameter; thirdly, selecting a simulation state from a state group according to the mode parameter, wherein the state group comprises a first state and a second state; and finally, selectively generating a replysignal according to the simulation state. In particular, the reply signal can comprise virtual identity information or virtual content information stored in the radio frequency identification tag.
Description
technical field [0001] The invention relates to radio frequency identification technology, in particular to a radio frequency identification tag and its operation method. Background technique [0002] Radio Frequency Identification (RFID) technology is a communication technology that uses wireless signals to identify specific targets and read and write data. Because there is no need to establish physical or optical contact between the data reader and the specific target, the convenience of data identification / reading and writing is better than that of traditional bar code devices. [0003] In view of the fact that radio frequency identification technology can be widely used in logistics management, shopping consumption, identification, smart homes and offices and other fields, and can bring a considerable degree of convenience, many companies have invested huge research and development budgets. However, in addition to the challenge that the cost has not yet fallen enough to...
