Abstract
The invention relates to a marking system comprising wires exhibiting ultrasoft ferromagnetic properties. Said wires are arranged on or in a carrier and are associated with pre-established parallel positions which are separated by a constant gap according to a pre-established frame. The wires can be present or absent in each position, forming a detectable binary code. The inventive marking system can especially be embodied as a magnetically coded label. The invention also relates to a method for producing one such marking system by continuously incorporating ferromagnetic wires into an adhesive complex. The inventive marking system is used to identify and authenticate articles, products or objects.
Claims19
A magnetic marking system, characterized in that it comprises, on or in a carrier, in correspondence with pre-established parallel positions separated by a constant gap according to a pre-established frame, one or more wires having ultrasoft ferromagnetic properties, these parallel wires being present or absent in each of said positions so as to form, through the set of wires present or absent, a detectable binary code.
A magnetic marking system, characterized in that the carrier is of the two-dimensional type and constituted by a sheet of adhesive-coated material, which fixes the wires having ultrasoft ferromagnetic properties in their pre-established positions.
