The sides have multiple layers: a first layer of dielectric material which substantially covers entirety of both sides, a second layer of structural material to add strength, and a third layer of soft material which protects any magnetic stripe on a card or the like from the dielectric material. The sides may be sealed by means of RF welding in order to minimize gaps between the sides. In use, the device prevents unauthorized RF remote access to the smart card chip or passport chip. ## Claims ### Claim 1 A smart card holder comprising: a body dimensioned and configured to hold a standard size smart card in an interior space, the body having first and second sides having rectangular planforms and four edges, the first and second sides joined at a plurality of the edges; the first and second sides having first and second layers of material, the first layer being a flexible transparent dielectric material covering substantially the entire rectangular planform of each side. ### Claim 2 (depends on 1) The smart card holder of claim 1, wherein the second layer is a decorative material and the first layer is disposed adjacent the interior space. ### Claim 3 (depends on 1) The smart card holder of claim 1, wherein the second layer is a strong structural material and the first layer is disposed adjacent the interior space. ### Claim 4 (depends on 1) The smart card holder of claim 1, further comprising a third layer of material, wherein the third layer is a soft material and the third layer is disposed adjacent the interior space. ### Claim 5 (depends on 1) The smart card holder of claim 1, wherein the first and second layers are joined at a plurality of edges by RF welding. ### Claim 6 (depends on 1) The smart card holder of claim 1, wherein the first layer is a 5 mil thickness of a plastic film sputter sprayed with silver and indium. ### Claim 7 (depends on 1) The smart card holder of claim 1, wherein the first and second sides are joined at three edges. ### Claim 8 (depends on 1) The smart card holder of claim 1, wherein the body is approximately 3.5 inches by 2.25 inches. ### Claim 9 A passport holder comprising: a body dimensioned and configured to hold a standard size passport in an interior space, the body having first and second sides having rectangular planforms and four edges, the first and second sides joined at a plurality of the edges; the first and second sides having first and second layers of material, the first layer being a flexible transparent dielectric material covering substantially the entire rectangular planform of each side. ### Claim 10 (depends on 9) The passport holder of claim 9, wherein the second layer is a decorative material and the first layer is disposed adjacent the interior space. ### Claim 11 (depends on 9) The passport holder of claim 9, wherein the second layer is a strong structural material and the first layer is disposed adjacent the interior space. ### Claim 12 (depends on 9) The passport holder of claim 9, further comprising a third layer of material, wherein the third layer is a soft material and the third layer is disposed adjacent the interior space. ### Claim 13 (depends on 9) The passport holder of claim 9, wherein the first and second layers are joined at a plurality of edges by RF welding. ### Claim 14 (depends on 9) The passport holder of claim 9, wherein the first layer is a 5 mil thickness of a plastic film sputter sprayed with silver and indium. ### Claim 15 (depends on 9) The passport holder of claim 9, wherein the first and second sides are joined at three edges. ### Claim 16 (depends on 9) The passport holder of claim 9, wherein the body is approximately 5 inches by 3.5 inches. ### Claim 17 A smart card holder for use with a wallet having a pocket, the holder comprising: at least one page dimensioned and configured to hold a standard size smart card in an interior pocket, the page having first and second sides having rectangular planforms and four edges, the first and second sides joined at a plurality of the edges and having at least one unjoined edge; the first and second sides having first layers of flexible dielectric material covering substantially the entire rectangular planform of each side; and an insert portion attached to the page, the insert portion dimensioned and configured to be inserted into such wallet pocket. ### Claim 18 (depends on 17) The smart card holder of claim 17, further comprising: at least a second page dimensioned and configured to hold a standard size smart card in an interior pocket, the second page having first and second sides having rectangular planforms and four edges, the first and second sides joined at a plurality of the edges; the first and second sides having first layers of flexible transparent dielectric material covering substantially the entire rectangular planform of each side, the second page attached to the first page. ### Claim 19 (depends on 18) The smart card holder of claim 18, further comprising: a cover sheet attached to the first page, the cover sheet having a first layer of flexible dielectric material, the cover sheet disposed so as to cover the unjoined edge of the first page.
