Design and implementation of automatic clearance control system based on RFID

The traditional method of customs examination can not satisfy the increasing demands of imports and exports of the vehicles. This paper designs a new automatic clearance control system based on Radio Frequency Identification (RFID) technology. The methods of how to improve security and secrecy of the system are discussed. Frequency disturb, the low power consumption and anti-jamming techniques are applied in the system. The bottom software and the protocol of the communication are also studied. Compared with the traditional ones, the test results manifest that the new system has preferable expansibility, high secrecy, fast read-write ability and automatic operation.
