Abstract
A radio-frequency identification (RFID)-based method and apparatus, per an implementation, comprises a first electrically-conductive loop and a first RFID integrated circuit (IC) assembly, a second electrically-conductive loop and a second RFID IC assembly, and a resonant antenna. When the first assembly, the second assembly, and the resonant antenna are brought within proximity of one another, such as when a connection is made among associated objects, a general symmetry is exhibited between a configuration of the first electrically-conductive loop and first RFID IC assembly relative to the resonant antenna, and a configuration of the second electrically-conductive loop and second RFID IC assembly relative to the resonant antenna. A generally corresponding RF signal phase and RF signal strength emanate from the first electrically-conductive loop and first RFID IC assembly and from the second electrically-conductive loop and second RFID IC assembly when interrogated by an RFID reader due to the general symmetry.
