RFID (RC522)

This project demonstrates how to interface an RC522 RFID reader with a RPi using Python. The RC522 communicates over SPI.

Hardware Required

• RC522 RFID module
• Jumper wires
• RFID tags/cards

Features

• Chip : It is based on the MFRC522 integrated circuit from NXP Semiconductors.
• Frequency : Operates at 13.56 MHz.
• Communication : It can communicate with a microcontroller using the SPI protocol & also supports I2C & UART.
• Reading : The RC522 module emits a radio signal via its antenna.
• Do not connect to 5V The RC522 is a 3.3V device.

Worked on Modules

• Raspberry Pi
• ESP32-C5
• Arduino
