13.56MHz RFID IC Key Tags Keyfobs 13.56MHz a modification for Arduino megaThis is 13. 56MHz RFID IC Key Tag. The RFID technology is used for sensing and identifying tagged people and objects for access control, automation, and a whole range of different applications. Operating on a frequency of 13. 56MHz, these tokens are all pre programmed with unique ID numbers to communicate wirelessly with RFID Readers over distances of around 1 Meter or less. This means you can attach it to vehicles or items, keyrings or even pets
