Reading RFid Tag Using Mifare RC522 and Raspberry Pi

Introduction

RC522 RFID modules are a simple add-on you can connect to a Raspberry Pi to read MIFARE tags and cards. This is potentially a great feature to include in a security system or any application where you need to identify an object or person without them pressing buttons, operating switches or other sensors.
