Abstract:
1. A magnetic marking system, comprising: a carrier defining pre-established parallel positions separated by a constant gap according to a pre-established frame, each position corresponding to a bit of a binary code; one or more wires having ultrasoft ferromagnetic properties provided on or in the carrier in correspondence with one or more of the pre-established parallel positions, the one or more wires being present or absent in each of said parallel positions so as to form, through a collective set of wires present or absent at the pre-established parallel positions, a detectable binary code, wherein each ultrasoft ferromagnetic wire is of identical nature, and the binary code is detectable without differentiation of magnetic properties or size of each of the one or more wires and without the provision of a hard magnet provided on the carrier.
