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 ...

This project is an RFID-based access control system built using an RFID/NFC module, RFID card, and keychain tags. The system reads the unique ID (UID) of RFID cards/tags and compares them with ...

[Jason] really wanted to build an RFID controlled garage door opener and decided to turn to Arduino to get the job done. For someone who’s never worked with an Arduino before, he really seemed to know ...

Abstract: This paper presents a combination of RFID and robotic technologies for developing a cloth-dressing robot system in the field of robot's body clothing innovation. By using the RFID as key ...

Abstract: Access control management is a very challenging task in an inter-enterprise RFID system due to huge amounts of information about things or objects that can be collected and accessed to and ...
