This project demonstrates how to use an RFID RC522 module with an Arduino to authenticate RFID cards. The system turns on a green LED if an authorized RFID card is scanned and turns on a red LED and ...

This project uses an RFID module (RC522) to create an access control system with Arduino. The system checks RFID tags against a stored authorized UID and provides visual and audio feedback based on ...

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.

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 ...

The card reader can be used two further enhance both Arduino and Raspberry Pi projects and is now available from just C$21 or roughly £13 with worldwide delivery expected to take place during ...

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 system's three most important components are an electrical locking mechanism, an Arduino microcontroller, and an RFID reader module. The RFID reader will verify the card's validity, and then the ...
