RC522 RFID Tag Reading with the Raspberry Pi

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. The contactless tags can be carried on a key-ring and the cards fit nicely in a wallet. Both of them can be hidden inside other objects to give them a unique ID that can be read by the Pi.

The obvious application is a security system where you use a tag to activate or deactivate an alarm but other applications include time and attendance systems and games.Read More
