1. A labeling system comprising:

  • a carrier film;

    a first electrically conductive layer formed as a deposit on said carrier film;

    a dielectric layer formed as a deposit on and at least partially covering said first electrically conductive layer;

    a second electrically conductive layer formed as a deposit on and at least partially covering said dielectric layer, said first and second electrically conductive layers being integrally joined to said dielectric layer to provide a composite label structure, said label structure having oppositely facing sides, with said carrier film being integrally associated with first portions of said label structure and separably associated with second portions of said label structure at one of said sides; and

    adhesive means arranged to coact with the other side of said label structure for applying said label structure to a receiving surface, said carrier film being separable from said second portions of the thus applied label structure with said first portions of said label structure remaining with said carrier film, said second portions defining an operable resonant circuit.
