Overview

Product Overview

The RC522 RFID Reader Writer Module 13.56MHz Kit for Arduino delivers a compact, ready-to-integrate solution for contactless identification projects and DIY security systems; operating at the global 13.56MHz standard, it supports common contactless smart cards and tags and connects via a fast SPI interface for reliable, low-latency communication, while offering both read and write capability for unique IDs and memory blocks to enable logging, access control, inventory tracking, and electronic door locks with straightforward Arduino integration and dependable performance.

Questions & answers

Frequently asked questions

Yes. The module is intended for Arduino projects and communicates through SPI, so it works with Arduino boards that can provide compatible SPI connections. It supports common 13.56 MHz contactless cards and tags, including MIFARE-style RFID use cases.
ShillehTek modules are sold with headers pre-soldered, so the board is ready for jumper-wire connections without soldering. Typical setup is wiring power and SPI pins, then using an Arduino MFRC522/RC522 library in your sketch.
The RC522 uses SPI for communication and operates at the 13.56 MHz RFID standard. RC522-based boards are 3.3V devices, so confirm power and logic-level compatibility when using 5V microcontrollers or shields.
Yes. It can read RFID tag IDs and write supported memory blocks, making it suitable for Arduino access control, attendance logging, inventory check-in, and electronic door lock projects. Door locks still require a proper relay or driver circuit.
Check that the tag is a compatible 13.56 MHz RFID card or fob, not a different-frequency access badge. Also verify SPI wiring, stable 3.3V power, shared ground, and that the software library pin assignments match your Arduino connections.
