Brief analysis of access control card system

The essence of the smart card system is to complete the device control system through smart card authentication. From the initial access control system, the smart card management system has gradually become a widely used one-card system. It involves almost every aspect of the operation and management of the unit. From the perspective of current applications, attendance, visitors, patrols, and meeting attendance have been derived. Many sub-system modules, such as consumer, item circulation, parking lot access, elevator control, etc., and with the expansion of requirements for personnel identity authentication and item certification, the application field of smart card systems is still expanding.

The construction of the card system is first to define the application scope and functions of the system, establish the application subsystem, and then choose a unified authentication medium, namely the selection of smart cards, and erect a unified one-card management platform. In this way, it can be ensured that multiple application subsystems share the same smart card, complete the basic data of all personnel in the system, and operate, store, and share the card reading information of each subsystem in a platform and a database to achieve access control, attendance, and The application functions of subsystem modules such as consumption. Unified with the smart card media, unified system platform is also an important indicator for the construction of the card system.

The card system platform centrally stores the cardholder's basic data information and card system operation data, and concentrates on the operation of the card system. The status in the entire system is extremely important. As an integral part of intelligent system integration, the card system should be an open system. The system platform can be linked and bundled in systems such as IBMS, BAS, and OA through OPC, SOCKET, and other standard interface protocols to achieve corresponding functional integration. Realize the linkage with the monitoring system, fire fighting system and equipment management system, and synchronize with the personnel data of the OA, HR and other unit operation management systems. For example: Through the data integration between systems, the basic data of cardholders in the card system can follow. Changes in relevant data of the human resources department are updated in a timely manner; the ERP system can obtain card attendance attendance information data in the card system in time.
