Claim:
1. A card comprising: a layer of non-magnetic electrically conductive material having an inner surface and outer surface; said inner and outer surfaces being generally planar and parallel to each other; a first assembly of electrically non-conductive material attached to the inner surface of the layer of non-magnetic electrically conductive material; and an electrically non-conducting protective coating overlying said outer surface for preventing said outer surface from making direct contact with any other surface; and wherein said protective coating forms the outer layer of the card and includes the following: (a) a clear coat layer of resin to provide electrical insulation to any surface it overlies; and (b) a hard top coat layer of electrically nonconductive nanoparticles in direct contact with and overlying the clear coat layer to provide both additional electrical insulation and protection against wear and tear and scratching to any surface it overlies; and wherein said clear coat layer and said hard top coat layer form the two outer layers of said card.
