NFC cell phone dynamic password entrance guard system and control method thereof

Abstract

An NFC cell phone dynamic password entrance guard system comprises a GSM module, a user module and a liquid crystal display, an NFC cell phone, an Arduino module, an NFC read-card module, a matrix keyboard and an alarm receiving center. The GSM module, the Arduino module and the NFC read-card module are connected in order. The GSM module is also connected with the alarm receiving center. The Arduino module is connected with the liquid crystal display. The matrix keyboard is connected with the Arduino module. Information transfer between the NFC cell phone and the Arduino module is realized through the NFC read-card module. The invention has the following beneficial effects: the function of updating a dynamic password during card-swiping of the NFC cell phone can be realized, there exists no recycled password, and security of the entrance guard system is enhanced.
