In the radio frequency identification technology, a matched transponder, such as a magnetic Card and an IC Card (Integrated Circuit Card), is required in the method, and the access control authority is confirmed by reading radio frequency tag information in the Card, but the current induction Card is not only easy to be forged and stolen, but also needs to be carried by a user, and is relatively serious in loss.
3. The biological characteristic identification technology mainly uses a sensor to acquire fingerprints, voice and human face characteristics to carry out biological individual uniqueness verification so as to judge the access control authority, but the identification needs a special sensor, wherein the fingerprint identification is in a contact type, is insanitary, is easy to copy, has weak voice identification anti-interference capability and low identification rate, and has complex human face identification algorithm, expensive sensor and high cost.
4. The short message telephone mode realizes the access control authority verification mainly by sending special information to a designated number or dialing a telephone, has certain time delay and needs to consider the problem of communication charge, and is not an economical and practical mode in the long run.
The access control systems have self limitations, and are not optimal choices particularly in laboratories of colleges and universities, office places and smart homes, so that a more reasonable scheme is needed to solve the contradiction.
