Changing Indicia in an electronic tag when tampered with
First Claim
Patent Images
1. An electronic seal comprising:
- an electronic tag;
an electrically resistive element in electrical communication with and attached to said tag, wherein tampering with the electrically resistive element causes a change in said electrical resistance, said change in electrical resistance being communicated to said tag, wherein said resistive element comprises a multiplicity of resistive wires, wherein only a random number of said wires are electrically connected to internal connection points in said tag such that said resistive element has a statistically random electrical resistance.

Abstract
An electronic seal including an electronic tag, an electrically resistive element in electrical communication with and attached to the tag, the resistive element being bondable to an object so as to define an electrical resistance, wherein a change in bonding of the element to the object causes a change in the electrical resistance, the change in electrical resistance being communicated to the tag.

9. An electronic seal comprising:
-
an electronic tag; an electrically resistive element in electrical communication with and attached to said tag, said resistive element being adhesively bondable to an object so as to define an electrical resistance, wherein a change in adhesive bonding of said element to said object causes a change in said electrical resistance, said change in electrical resistance being communicated to said tag, wherein said resistive element is bonded to said tag with an electrically conductive adhesive having an adhesive strength, said element being bonded to said object with an adhesive strength greater than the adhesive strength of said conductive adhesive.
