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 ...

The use of Radio Frequency IDentification (RFID) technologies is growing. Many different applications are implemented in various sectors, and used for very different purposes. RFID enables wireless ...

Abstract: Among the many potential applications of inexpensive radio frequency identification (RFID) technology are security, tracking assets, people monitoring, supply recognition, and access control ...

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 ...

As vehicle access-control systems utilizing UHF RFID are gaining traction among gated communities, parking lots and other controlled areas, the cost has still been challenging. Readers deployed at ...
