The vehicle license plate and the vehicle certificate information can be encrypted and written into the area, and the anti-counterfeiting characteristic is high in this point. Through the inspection of the reader-writer on the passing vehicles, the possession of a fake certificate or an illegal vehicle is easily recognized.
(2) And (4) borrowing prevention. Because the information of the number plate of the vehicle can be encrypted and written into the label and the information data in the system database is called, whether a certain vehicle has the right to use the vehicle certificate (namely, the electronic label) can be distinguished, thereby preventing the phenomenon of borrowing the vehicle certificate and realizing the unification of the certificate and the vehicle or the unification of the certificate, the vehicle and a driver.
(3) And 4, preventing the theft. If a certain vehicle certificate is lost carelessly, whether a certain vehicle has the right to use the vehicle certificate or not can be judged from the unification of the vehicle certificate number and the vehicle certificate through the means, the vehicle certificate can be disabled through a loss report method, and once the vehicle tries to get out through the loss report vehicle certificate, the vehicle certificate can be identified.
(4) And (4) preventing disassembly. Each electronic tag is attached with an anti-disassembly function, and once the electronic tag is disassembled after being installed, the electronic tag cannot work, so that the electronic tag is prevented from being repeatedly used or used after being disassembled, the one-to-one correspondence relationship between the electronic tag and an identified vehicle is ensured, and the real marking function of the electronic tag is achieved.
