The Arduino acts as the brains of the operation while an off-the-shelf NFC/RFID reader module is used to read the RFID tags. To add new keys to the system, [Jason] simply swipes his “master ...

– MFRC522 connection header: This is where the MFRC522 RFID reader connects to the main board. – Program select header: Currently, only header#1 is being used in the program.

The project takes an MRFC-522 RFID module and explains how to interface it to an Arduino. In this case the Arduino in question is an Arduino Pro Micro chosen for its ability to be a USB host.

Instructables user talk2bruce created the Arduino Internet Gizmo, a card reader that takes you to your favorite websites with a touch of an RFID tag.

The M6e-Micro module represents a significant step in supporting this innovation," said Tom Grant, general manager of Trimble’s ThingMagic Division.
