3. 访问控制： 通过设置不同的权限和密码，考勤门禁系统可以实现对不同区域和设施的访问控制。只有经过授权的用户才能进入特定区域或使用特定设施，确保场所的安全和秩序。 三、英文翻译 Design Principle and Application Practice of Attendance Access Control System The attendance access control system is a comprehensive system that integrates various technologies such as electronic technology, computer technology, and security technology. Its design principle is mainly based on the following aspects: I. Design Principle: 1. Hardware Composition: The attendance access control system mainly consists of a reader, controller, electric lock, communication module, and other hardware. The reader is used to read user identity information, the controller is responsible for processing the information read by the reader and controlling the switch of the electric lock, and the communication module is responsible for data interaction with the backend server. 2. Software Algorithm: The system uses software algorithms to identify, process, and store the identity information read by the reader. The software algorithm can recognize valid and invalid cards, record entry and exit time, location information, and provide data support for subsequent attendance statistics and safety management. 3. Security Mechanism: The attendance access control system employs a multi-layer security mechanism, including password verification, biometric identification (such as fingerprint, iris), dynamic verification codes, etc., to ensure that only authorized users can pass through the access control system. At the same time, the system also has functions such as anti-tailgating and anti-hijacking to improve system security. II. Application Practice:

The attendance access control system is widely used in enterprises, schools, hospitals, government agencies, and other places. Its application practice is mainly reflected in the following aspects:

1. Attendance Management: Enterprises can accurately record the entry and exit time and location of employees through the attendance access control system, facilitating attendance statistics and assessments. At the same time, the system can automatically generate attendance reports to improve management efficiency. 2. Safety Management: The attendance access control system can be linked with other security systems such as video monitoring systems to achieve real-time monitoring and recording of incoming and outgoing personnel. In case of abnormalities, the system can promptly alert and notify relevant personnel to deal with it, improving the safety of the place. 3. Access Control: By setting different permissions and passwords, the attendance access control system can achieve access control for different areas and facilities. Only authorized users can enter specific areas or use specific facilities to ensure the safety and order of the place.
