1. A method of making a flexible identification tag capable of withstanding considerable stresses experienced in mail processing equipment, the method comprising:

  • providing a single layer of a flexible substrate having an antenna portion, and an integrated circuit portion;

    forming an antenna on the antenna portion of said substrate wherein said antenna is formed over substantially most of said flexible substrate;

    forming a sensing circuit on the integrated circuit portion of said substrate, wherein said sensing circuit is formed in an area of said substrate separate and adjacent to said antenna portion;

    forming a connection between said sensing circuit and said antenna of said substrate;

    encapsulating the sensing circuit to form a semi-rigid area on said substrate while said antenna portion remains flexible; and

    forming an ink dam around said semi-rigid area to retain said encapsulating material within said semi-rigid area.
