2 sets of RFID RC522 Card Reader Module (13.56MHz) for Arduino, ESP32, Raspberry Pi – With Key Fob & Card

Upgrade your access control, attendance, door lock, or ID projects with the RFID RC522 / MFRC522 module, a reliable 13.56MHz RFID reader module for Arduino and many other boards. This is the popular RC522 RFID reader Arduino SPI module that comes with a RFID key fob 13.56mhz and a card, making it perfect for learning, prototyping, and building real projects.

If you’re searching for an rfid module arduino or an arduino rfid reader module, this is the best value option for makers, students, and technicians in Uganda. The RC522 works through SPI and is widely supported by Arduino libraries, making it easy to read UID numbers from a mifare key fob blue or a rfid key tag 13.56mhz.

Why this RFID Module?

✅ Works with Arduino + other boards: Ideal as an rfid module arduino for Uno/Nano/Mega and also compatible as an rfid reader module for esp32, ESP8266, and Raspberry Pi projects.

✅ Reads 13.56MHz tags: Supports common MIFARE tags including mifare 1k key fob and standard cards.

✅ SPI Interface: Stable, fast and easy wiring as an RFID reader module for Arduino Uno and other boards using SPI pins.

✅ Great for projects: Door locks, access systems, attendance tracking, inventory, student ID scanning, smart lockers, and IoT.
