Patent ID: 7675123

Claim:
A first passive memory device comprising a support with two sides and provided with a passive memory element on at least one side thereof, said support having a conductive surface or surface layer on the at least one side provided with said passive memory element, said passive memory element comprising a first electrode system and a second electrode system, wherein the first electrode system is insulated from the second electrode system by a patterned insulating system, wherein the first electrode system is a conductive surface, or a conductive layer; wherein said second electrode system is a plurality of isolated conductive areas optionally together with a plurality of conductive pins isolated from one another; wherein conductive bridges are present between at least one of said isolated conductive areas of said second electrode system and said first electrode system; wherein in the absence of said at least one conductive bridge there is no direct electrical contact between said first and said second patterned electrode systems; and wherein, with the exception of said first electrode system being the conductive surface of a metallic support, said systems and said conductive bridges are printable using conventional printing processes, wherein said first passive memory device is transparent.
