Development of an RFID-based security door system

This paper describes the development of a two-factor radio frequency identification (RFID)-based security door authentication scheme that can provide efficient control facilities to restrict the entry of an unauthorised door user. The developed system consists of the RFID unit, a microcontroller programmed to control the operation of the door using a synchronous motor. The multiplexers that comprise integrated circuits combined with the liquid crystal display was utilized for displaying the status of the card user while the alarm system informs the public of an intruder. The experimental results are presented and discussed.
