1. A tag arranged to reflect electromagnetic energy for the purpose of indicating the presence of said tag, said tag comprising a substrate having a surface, comprising:

  • a. a preformed first patterned adhesive disposed over said surface of said substrate;

    b. a first layer of electrically conductive material having a shape corresponding to a desired final pattern for a first electrically conductive trace secured to said surface of said substrate by said preformed first patterned adhesive wherein said preformed first patterned adhesive corresponds to said desired final pattern;

    c. a second patterned adhesive disposed over a portion of a surface area of said tag, said surface area comprising said surface and said first electrically conductive trace;

    d. a second electrically conductive trace disposed over said second patterned adhesive to adhere said second electrically conductive trace thereto; and

    e. an electrical connection for electrically coupling portions of said first and second electrically conductive traces to form a tag circuit.
