Tapes for marking valuable components and their housings and supporting posts are described along with a process for utilizing the tapes including the steps of sequentially marking the copper and the equipment with a MR marking (e.g. barcodes, Q-R codes and/or EF transmitters). EF or related broadcasting transmitters or their equivalent would be thin enough and responsive to a signal; machine reading a MR sequence on copper that is brought; marking the copper sold before, after or at the point of sale; identifying the location and coding the copper as stolen at the point of theft, utilizing a nationwide system of copper marking tied to the buyer's information; visually marking the copper in a non-sequential way, potentially by region or state in order to minimize the amount of overlap and would also include the concepts of mandatory scanning of copper products at installation or recycling.
