Design Fingerprint Attendance Machine Based on C51 Single-chip Microcomputer

摘要

Fingerprint attendance system marked by the fingerprint template for authentication, utterly eliminates false phenomenon for fingerprint attendance system by any people's fingerprint uniqueness, effectively puts an end to the human factors of attendance management, fully embodies the justice of attendance management, and avoids 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, fingerprint identification module as sensors. Taking students in class as an example, student ID can be displayed on the fingerprint attendance system when fingerprint come input, and record attendance will be stored. The manager has a clear understanding for the students' attendance information in class, in addition, the information stored in this system can be arbitrarily increased or deleted, the function of this system is simple and practical.
