Abstract
A method, system and apparatus for pairing authorized NFC enabled RFID devices with an intended object or product. The method, system and apparatus can include a primary RFID with a radio frequency identification chip, a coil antenna, a bridge and a substrate; an association of the at least primary RFID device with an object; an integration of a material into one of the at least primary RFID device and the object that provides the RFID device with a predetermined resonant frequency; and the detuning of one or more secondary communication devices located proximate the RFID device.
