Wireless Fingerprint Attendance System Based on ZigBee Technology

Abstract

Aiming at the disadvantages of traditional wire attendance system, a design method of wireless fingerprint attendance system based on ZigBee technology is proposed. The system includes terminal fingerprint acquisition module and attendance management module in computer. It can realize automatically such functions as information acquisition of fingerprint, processing, wireless transmission, fingerprint matching, and attendance management. Considering the fact and topology of ZigBee network, the system designs wireless local area network which is cluster tree network. To resolve the problem of time delay when the image is transmitted by ZigBee technology, the traditional transmission mode is improved. The experiment results show the transmission time is saved over one third and transmission efficiency is improved greatly. It realized low-cost and high-performance wireless fingerprint attendance function, which provided a new wireless fingerprint attendance system for enterprises and institutions.
