Radio Frequency Identification (RFID) is a common technology used for access control in schools and offices, animal identification, and product asset tracking. The MFRC522 module is a 13.56MHz RFID reader/writer that uses SPI to communicate with devices. The MFRC522 is compatible with both Arduino and Raspberry Pi, and a large range of RFID tags and cards. The kit we have assembled comes with an MFRC522 module, 6 RFID tags (3 fobs, 3 cards), and a 3D printed fixture for holding the MFRC522 - which makes getting started with RFID for Arduino very easy.

Included in the MFRC522 RFID Kit for Arduino:

• 1x MFRC522 RFID Module

• 6x RFID Tags (3x Cards, 3x Fobs)

• 1x 3D Printed Fixture

• 4x M3 Screws and Nuts for Affixing the MFRC522 Module to the Fixture

• 9x Female-to-Male Jumper Wires

Some Features of the MFRC522 RFID Module:

• 3.3V and 5.0V Supply Voltage

• 13.56MHz Operating Frequency

• SPI Communication (Arduino, Raspberry Pi Compatible)

• Capable of Communication with MIFARE Tags

• 10cm Read Range (between tag and reader)

• Active Area: 30mm x 30mm

• Module Dimensions: 36mm x 36mm x 7.5mm (accounting for pin headers)

• MFRC522 Datasheet

• See our tutorial on the MFRC522 with Arduino!
