Arduino-UNO-SIM808-RFID-RC522-Vehicle-Tracking The project implements Arduino UNO as a base controller. It utilized SIM808 for GSM, GPS and GPRS connectivity. The project also implements RFID module ...

RFID Tag Detection with Arduino This project demonstrates how to detect RFID tags using an Arduino and an RFID-RC522 module. When an RFID tag is brought near the reader, the unique ID (UID) of the tag ...

Therefore, an effort was made to design a tool for “identification of impedance changes in metals using an Arduino Uno-based RFID RC522” which is relatively inexpensive and easy to carry.

The MFRC522 requires a regulated 3.3v power supply, which is provided on the board, so that you don’t have to worry about it! – MFRC522 connection header: This is where the MFRC522 RFID reader ...
