Radio-frequency identification (RFID) devices are used in a variety of applications to facilitate the identification and tracking of people, objects, and animals. One problem with RFID devices or tags concerns manufacturing cost. Specifically, some tag designs use an integrated-circuit chip requiring three external connections, instead of two as do many other designs. Accordingly, the present inventor devised a unique RFID module which uses a three-terminal integrated circuit and two capacitors, but only requires two external leads. One exemplary embodiment of the module includes two external terminals for connection to an antenna coil and an internal terminal for connection to a center-tap of a dual (center-tapped) capacitor. Other aspects of the invention include subcomponents of the module and methods of tag assembly using the module.
