Abstract

Briefly stated a tag (10) includes a dielectric substrate having first and second opposite principal surfaces. An electrical circuit having an electrically conductive pattern (18) is formed on at least one of the principal surfaces of the dielectric substrate, the conductive pattern including a gap (22) which establishes an electrical open circuit. An electrically conductive composition (24) including electro-conductive particles (24) is provided for bridging the gap in the conductive pattern to temporarily establish an electrical closed circuit which resonates when exposed to electromagnetic energy at a frequency within a predetermined frequency.
