Abstract:
1. A wireless RFID transponder, comprising: a non-metallic housing attachable directly to a metallic implement to be RFID tagged, the metallic implement being separate and discrete from the wireless RFID transponder, the metallic implement having a metallic body and an absence of an antenna; an RFID chip within said housing, said RFID chip being mechanically connected to said housing; and an inductive coupler within said housing and electrically connected with said RFID chip, said inductive coupler being impedance matched to the metallic implement to inductively couple with the metallic implement external and immediately adjacent to said housing and thereby effectively utilizing the metallic implement as an antenna for said RFID chip so that the RFID transponder can wirelessly communicate information with an RFID reader.
