Abstract:
Radio frequency identification (RFID) devices, and methods of manufacture are described herein. In one implementation, a RFID device comprises: a near field only RFID tag that does not function as a far field RFID tag and is pre-manufactured; and a conductive element independent from the near field only RFID tag and configured to function as a far field antenna. The near field only RFID tag and the conductive element are coupled in proximity to each other such that the RFID device functions in both a near field and a far field.
