Fingerprint Attendance Machine Design Based on C51 Single-Chip Microcomputer

Fingerprint attendance system marked by the fingerprint template for authentication utterly eliminates error for fingerprint attendance system by any people's fingerprint uniqueness, effectively putting an end to the human factors of attendance management, fully embodying the justice of attendance management, and avoiding unnecessary personnel disputes. This system uses the STC89C52 microcontroller as the main control chip, 12864 LCD as the man-machine interface, matrix keyboard as input student ID and fingerprint identification module as sensors. Taking students in class as an example, student ID can be displayed on the fingerprint attendance system when fingerprint is input, and record attendance will be stored. The manager has a clear understanding of students' attendance information in class. In addition, the information stored in this system can be arbitrarily increased or deleted, the function is simple and practical.
