Flexible scanner resistant device emulating a banknote for protection of rfid cards

A method for preventing radio frequency scanning of a card, comprising:

• placing a first rectangular-shaped planar element within a banknote slot of a personal carrying case such that the first planar element is located substantially around one or more cards within the personal carrying case, wherein the planar element is sized for fitting within a banknote slot of the personal carrying case, wherein the planar element is substantially from about 7 and ¾ inches in length, to about 2 and ⅞ in width, and wherein the planar element is composed of a top layer of plastic material having an interior surface including printed information, a middle layer of a metallic foil that inhibits the transmission of radio frequency signals, and a bottom layer of plastic material having an interior surface including printed information, wherein the top layer and the bottom layer of plastic material completely cover a surface area of both sides of the middle layer.

A system for preventing radio frequency scanning of a card, comprising:

• a personal carrying case comprising a plurality of card slots for inserting cards and a banknote slot for inserting banknotes;
• at least one card including information that may be scanned via a radio frequency scanner, wherein said at least one card is inserted into the plurality of card slots;
• a rectangular-shaped planar element sized for fitting within the banknote slot of the personal carrying accessory, wherein the planar element is composed of a top layer of plastic material having an interior surface including printed information, a middle layer of a metallic foil that inhibits the transmission of radio frequency signals, and a bottom layer of plastic material having an interior surface including printed information, wherein the top layer and the bottom layer of plastic material completely cover a surface area of both sides of the middle layer, and wherein the device has a thickness of about 0.3 mm and exhibits a bending stiffness substantially equal to paper.
