An ISO15693 based entrance access control system: Design, implement and key issues

A novel IS015693 based entrance access control system was design in this paper. The system, that allows the identification and authentication of people, controls their access to restricted areas. The main component of the system is antennas, reader, tags and service application engine. When the antenna detected someone, who passes though the entrance, without authorized, the peripheral devices can do the corresponding action according to the user configure. This system can be used in conference registration, building visiting reception and staff attendance record. It´s an innovation of traditional entrance access management mode. In order to enhance the system reliability, a fast query tree (FQT) anti- collision protocol was proposed. It uses manchester code violation, which can detect the individual collision bit, and use the information of the last query cycle to reduce the current query latency. Combined with mixed antennas mode technique, this system is successfully used in many Chinese institutions.
