RFID-Based Attendance System using Arduino

The RFID-Based Attendance System is a smart and contactless method to record attendance using RFID technology. It uses an Arduino Uno, RC522 RFID reader, and RFID tags/cards assigned to individuals.

When a person taps their RFID card near the reader, the system reads the card’s UID and checks it against pre-stored data in the Arduino. If the UID is valid, a 16×2 LCD (with I2C) displays a message like “Attendance Marked”, and a buzzer or LED can signal a successful scan. Invalid cards show an “Access Denied” message.
