iDTRONIC’s Contactless RFID Cards provide many advantages, due to their non-required physical link with the reading device. The communication is performed through the electro-magnetic field between the Reader and the Contactless Card. The cards feature a long lifespan and are resistant to dirt and moisture. The main components of a Contactless Card are a microchip and an antenna. The microchip controls all communication with the reader, as well as data storage, data encryption and security of access.
