ABSTRACT:
A reader section has a reader circuit connected to three parallel metal plates. The center plate is excited by an alternating voltage and the other two plates are excited by an inverse voltage. An identifier section has an identifier circuit connected to a metal plate identifier antenna. The electric field created by the metal plates of the reader antenna is detected by the identifier section and an identifier signal is generated in response thereto.
