Product Description

The MFRC-522 RC522 RFID Module Kit is engineered for users who need a reliable RFID reader/writer for 13.56MHz contactless applications. Built around the NXP MFRC522 chip, it supports ISO14443A protocol and employs advanced modulation and demodulation for smooth communication. The module allows two-way data transfer up to 424 kbit/s and communicates via SPI for efficient wiring and integration.

This kit is ideal for RFID-based projects such as:

  • Access control systems
  • Door lock automation
  • Time attendance recording
  • Smart card identification

With all core components included, this kit offers a simple yet powerful platform for RFID experimentation and development.
