In this Raspberry Pi RFID RC522 tutorial, I will be walking you through the steps on how to setup and wire the RFID RC522 chip with your Raspberry Pi. This is a cool circuit to play around with and opens you up to quite a wide variety of different projects from using it as an attendance system to using it to open a lock.
The RFID RC522 is a very low-cost RFID (Radio-frequency identification) reader and writer that is based on the MFRC522 microcontroller. This microcontroller provides its data through the SPI protocol, and works by creating a 13.56MHz electromagnetic field that it uses to communicate with the RFID tags.
