🧠 Working Principle

The RFID Key Ring Tag operates using radio frequency identification technology. When the tag comes within the electromagnetic field of an RC522 Reader, it powers up through induction and transmits its unique ID data via radio frequency.

The RC522 module reads this data and sends it to the microcontroller (like Arduino or ESP32) for further processing — such as granting access, logging attendance, or activating systems.

This contactless communication makes it ideal for touch-free authentication, automated entry systems, and smart IoT applications.
