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 ...

RFID Module: Reads the UID from an RFID tag/card. If the UID matches the authorized UID, access is granted. This project is open-source and can be freely used for educational purposes. I demonstrate ...

A Lock Box that uses RFID, an SD card, and an Arduino to open and close the box and log who and when someone opens it. RFID machine access solution for a Fab Lab, based on ESP32. Uses modern C++ with ...

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 ...

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 ...

Abstract: Identification of corrosion in the tool industry is very important because it minimizes the impacts and losses due to damage to the tools used. Although there is already a corrosion ...

Radio Frequency Identification (RFID) technology is a system capable of identifying objects through a unique identifier (UID). The RFID system consists of two main components: an RFID tag and an RFID ...
