Project description
This project show how to build a log of using RFID cards with Arduino Uno, Ethernet Shield and RC522 RFID reader. author used web technologies such as PHP and mySQL. This is system block diagram. when RFID reader read a tag, UNO check unique UID and compare with uniqur UID in code. If it's same runs a PHP script via http request that updates the database with the date and time of card use and its ID. If the authorization was successful, the green LED lights up.
