With the development of science and technology, security technology has developed rapidly. Access control system is commonly used in more and more places. For the application of RFID technology in the access control system, it not only promotes technological innovation of the access control system, also prompts access control systeym open development.

With the development of induction card technology and the biological recognition technology in the recents years, access contol system began to enter the mature period so that the access control system of induction card, fingerprint , iris, face recognition and other technologies appears, and each of them has special features in the aspects of the security, convenience. These techniques is widely used in the field of access control system.

So what is RFID technology? RFID is called radio frequency identification technology. It uses radio frequency to conduct non-contact two-way communicatio in order to achieve the purpose of identification and data exchange, and this technique it is often used for highway. it realizes multiple targets recognition by RFID. It can realizes the movement of the object recognition and remote real-time monitoring and management. Its advantages are automatic identification, tracking target object, can adapt to the environment, and is affected by rain, snow, hail, fog and so on.

Since RFID technology is integrated into the access control system, it has already surpassed the traditional doorways and key management functions. The safety requirements of the modern working environment, the administrative management of the department, the daily attendance management and the company's catering consumption are all closely related to the access control system. Such as apartment, residential area, factory patrol, company research and development technology department, medical unit free of disturb area, financial and finance department, all are the best place for RFID access system application. It can effectively prevent unauthorized person from entering the area and protect the safety of these sites to the maximum extent.

RFID technology is constantly injecting new impetus into the development of the access control system, and it is constantly making the access control system more open and creating the convenience for peoples life.
