A method of and apparatus for identifying an item to or with which a radio frequency identification tag is attached or associated is provided. The tag is made of a nonconductive material to have a flat surface on which a plurality of circuits are pressed, stamped, etched or otherwise positioned. Each circuit has a capacitance and an inductance. The capacitance is formed from the capacitive value of a single capacitor. The inductance is formed from the inductive value of a single inductor coil having two conductive ends each connected to the capacitor. Ea...
A tag which uses radio frequency waves transmitted from a scanning device in order to identify an item to which said tag is attached or with which said tag is associated comprising: an insulating layer having a top surface, a bottom surface, and side surfaces; thin conductive metallic means adjacent either said top surface or said bottom surface of said tag for forming a plurality of circuits, wherein each circuit of said plurality of circuits has a unique resonant frequency formed by one-to-one correspondence of a capacitance made up of a single capacit...
