To strengthen campus access control and attendance management, the university has actively promoted the "Campus RFID Smart Card." Access control has been implemented in dormitories, elevators, research rooms, library discussion areas, network server rooms, and some computer labs. Authentication services also cover campus information stations, printing services, public computers in the library, event check-in/out, and attendance management. Integrated with the LDAP authentication system, this system creates a convenient and comfortable tech-enabled campus life. All faculty, staff, and students have received the new Campus RFID Smart Card with EasyCard functionality, providing electronic payment capability within campus commercial areas. The overall system architecture is illustrated below.
