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. Each tag is associated with a binary number established from a pattern of binary ones and zeros which depend on the resonance or nonresonance of each circuit, respectively and the circuits position with respect to the binary table. The binary number may be converted to a decimal number using the binary table for conversion.
