Abstract
Briefly stated a tag includes a dielectric substrate having first and second opposite principal surfaces. An electrical circuit having an electrically conductive pattern is formed on at least one of the principal surfaces of the dielectric substrate, the conductive pattern including a gap which establishes an electrical open circuit. An electrically conductive composition including electro-conductive particles 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 range.
