01 — About

What it does

The RC522 RFID Module for Arduino & Raspberry PI enables wireless contactless communication with RFID cards and tags at 13.56MHz. It supports MIFARE Classic cards for access control, identification, and contactless data applications.

Key features

  • 13.56MHz frequency ISO 14443A compliant
  • Supports MIFARE Classic 1K and 4K cards
  • SPI/I2C/UART interfaces for flexible connection
  • Read/Write capability for card data storage
  • 3.3V operation with 5V tolerant input pins
  • Built-in antenna with up to 10cm range
  • Compact module with included card and key fob

Good to know

  • Module operates at 3.3V – do not connect 5V directly to data pins
  • Use MFRC522 library by miguelbalboa for Arduino
  • Default I2C address conflicts may occur – use SPI for best results
  • Card must be within a few centimeters for reliable reading
  • MIFARE Classic security is compromised – not for high-security applications
