An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive ...

A simple Arduino project using the MFRC522 RFID module to read and display RFID tag UIDs on the Serial Monitor. This project uses an RFID-RC522 module with Arduino to read RFID tags and display the ...

MFRC522 Arduino library for MFRC522 and other RFID RC522 based modules. Read and write different types of Radio-Frequency IDentification (RFID) cards on your Arduino using a RC522 based reader ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

Radio Frequency Identification is widely used in contactless payment cards, National Highway Tollgate systems, and in security passes. By integrating an RFID reader with an Arduino, you will be able ...
