A method for producing shape memory anti-counterfeiting identifier includes the following steps: a high polymer material with a shape memory function without the need of sunshine cross-linking or chemical cross-linking is directly extruded to become sheet in an extruder or is injected to be molded in an injection molding machine, and the extruded sheet can be a planar sheet or a sheet having a surface on which concave-convex patterns or characters are formed; the above sheet is then heated to the temperature higher than the vitrification temperature and lower than the melting point temperature, and the patterns or characters are pressed on the planar sheet, or the sheet on which the concave-convex patterns or characters are already formed is pressed to become planes or other patterns and characters; the sheet is then cut into small sheets, wherein one pattern or one group of characters is implied on every small sheet, and when the small sheets are again heated to the temperature higher than the vitrification temperature and lower than the melting point temperature, they will return to the extruded state.

A manufacturing assembly for the creation of laminate constructions includes a calendar device arranged to accept a laminate of three or more layers of material stock, as provided by a matching three or more rolls of the material stock. A sheeting device is arranged downstream from the calendar device for cutting the laminate into predetermined sizes, such that the laminate is kept in a non-rolled, planar orientation subsequent to the laminate exiting the calendar and before the laminate is sheeted by the sheeting device.

An identification patch having a pattern of plasmonic resonance elements may be used to ensure that an article is counterfeit-proof. The identification patch is formed by laser-induced superplasticity to create a distinctive pattern of resonance elements that each contain a plurality of nanostructures. When the identification patch is irradiated, the pattern of resonance elements produces a unique spectral response that is associated only with the counterfeit-proof article. The counterfeit-proof article may be a metal component or an integrated circuit. The resonant absorption of the plasmonic resonance elements may be measured to verify the authenticity of the article before use of the article.

A secure multi-layered structure (14), for example, for a secure document, the secure multi-layered structure comprising a first layer (20) having a first aperture (25) opened in the first layer, a second layer (30) having a second aperture (35) opened in the second layer, and a third layer (40) having a third aperture (45) opened in the third layer, wherein each layer at least partially overlaps with the layer adjacent to it, at least a portion of the third layer being visible through the first aperture.

A manufacturing process that allows for the transfer of labels formed from polarizer film to end-use products. The polarizer film is covered by a masking layer that is typically die cut to create the labels from the continuous sheet of film. Here, an additional covering layer (or layers) of a relatively stiff material is disposed over the masking layer. The addition of the covering layer results in the processed polarizer film being less susceptible to damage (related to unwanted bending) during further processing and/or shipment. Advantageously, the covering layer improves the ability to remove individual labels from the film, particularly with respect to attempting to peel off the thin masking layer.

A method of making a metallic credit card from an existing plastic credit card including the steps of cutting the existing plastic credit card from each side edge, peeling the plastic top layer from its bottom plastic substrate, removing its EMV chip, and attaching it to a metallic substrate. The metallic substrate can further be laser engraved with the user's personal information.
