1. A system, comprising:

  • a first conductive element;

    a second conductive element; and

    a capacitive encoder adapted to drive the first conductive element with a first RF signal and to drive the second conductive element with a second RF signal, wherein the second RF signal is out of phase with the first RF signal by a predetermined phase so as to capacitively excite an RFID tag in proximity to the first and second conductive elements.
