RFID is the abbreviation of Radio frequency identification. Let's first have a little introduction of RFID and then we will look into how to interface RC522 with Arduino. In this project I have used it for for student attendance so I thought to share it on our blog so that other engineers could get benefit out it. I recently get a chance to work on a project in which I have to use RFID reader to scan cards. In short, its a new emerging technology which is quite useful. We have seen it in many movies that when someone places ones card over some machine then door opens or closes. Now-a-days it is extensively used in offices where employees are issued an RFID card and their attendance is marked when they touch their card to rfid reader. Its a new technology and is expanding day by day. It is an RFID module and is used for scanning RFID cards. RC522 is very simple yet effective module. Today's post is about interfacing of RFID module RC522 with Arduino. Hello friends, hope you all are fine and having fun with your lives.
