A card manufacturing system includes a locating device and a separation device. A laminate sheet comprising a plurality of cards is received by the locating device and is imaged using first and second imaging modalities. The first imaging modality identifies a location of each of the plurality of information carrying cards within the laminate sheet and the second imaging modality images at least one graphic formed on a surface of the laminate sheet. A position of the at least one graphic with respect to at least one information carrying card is determined and the plurality of cards are removed from the laminate sheet using information corresponding to the location of each of the plurality of information carrying cards when the position of the at least one graphic with respect to the information carrying cards is within a predetermined range.

A security marking has a physically unclonable function (PUF) wherein the PUF includes a disordered multilayer photonic crystal structure having an electromagnetic transmission and/or reflection spectrum and/or spectra upon receipt of electromagnetic radiation within a photonic bandgap region of the structure that is unique to the structure.

Provided is a laminated body in which a print layer is provided downstream of a laser color development layer without lowering quality. A card is provided with an offset print layer laminated on a base material, a buffer layer laminated on the offset print layer and having translucency, and a laser color development layer laminated on the buffer layer. The buffer layer minimizes scratches on the offset print layer that occur with the heat generation of the laser color development layer.

The invention relates to an optical structure (5) having a relief effect, comprising: - a support (7) adapted for aligning liquid crystals, - a deposit (9) in contact with the support of a substance in the form of at least one pattern (11), which partially covers the support, and - a liquid crystal layer (13) which at least partially covers the support and said pattern and is in contact with the support.

A transaction card includes an anodized card body having a front and rear face. Various information and security features may be provided on the front face and on the rear face. A magnetic stripe may be provided on the rear face of the anodized card body. The magnetic stripe may be adhered within a slot formed within the rear face of the anodized body. Alternatively, the magnetic stripe may be provided via an overlay that is adhered to the rear face of the anodized body, and the magnetic stripe may be integral with the overlay or adhered to the overlay after the overlay is applied to the anodized card body. The transaction card may also include a hologram. The hologram may be integral with the overlay or may be applied to the overlay that has been arranged on the anodized card body.

A security print medium for forming security documents therefrom, the security print medium comprising a core having opposing first and second sides. The core comprises a radiation-responsive substance distributed within the core across at least a first region of the core, the radiation-responsive substance being responsive to a predetermined input radiation by producing a predetermined output radiation. The security print medium further comprises a first encoding layer disposed on the first side of the core and a second encoding layer disposed on the second side of the core, each of the first and second encoding layers comprising an encoding material that modifies the intensity of the predetermined input radiation and/or the predetermined output radiation produced by the radiation-responsive substance transmitted through the respective encoding layer, wherein the first and second encoding layers overlap each other across the first region. The optical density of each of the first and second encoding layers varies across the first region in accordance with a predetermined pattern, the predetermined pattern defining one or more encoding features, such that when the security print medium is exposed to the predetermined input radiation, the output radiation detectable from one or each side of the security print medium varies across the first region in accordance with the one or more encoding features. The first and second encoding layers are configured such that when the security print medium is viewed in transmitted visible light, the intensity of visible light transmitted through the first encoding layer, the core and the second encoding layer in combination is uniform across the first region, such that the one or more encoding features is concealed.

A resin card medium which has a substrate having electronic components mounted thereon and has sophisticated flatness and smoothness realized without providing any layer having holes for absorbing thicknesses of the electronic components; and a method for manufacturing a resin card medium. A resin card medium laminated body before pressing is prepared by laminating, on a first plastic finishing sheet, a substrate having one electronic component or two or more electronic components installed on one side of the substrate, with the one side, on which the electronic component or electronic components are installed, facing upward, and laminating, on the substrate, mixed paper constituted of plastic fibers and plant fibers, and by subjecting the resin card medium laminated body to hot pressing at a temperature which is a softening point or more of the plastic fibers and less than a melting point of the plastic fibers.

A security insert with at least one optically recognizable character and at least one tactilely detectable character for an identity document comprises at least a first at least partially transparent layer which has blackenings which form at least one optically recognizable character. A varnish arrangement forming at least one tactilely detectable character is disposed on a layer of the security insert. The at least one optically recognizable character is, at least from the perspective of an observer of the security insert, partially overlaid by the at least one tactilely detectable character, wherein at least a portion of the outer contours of the at least one tactilely detectable character is optically recognizably reproduced by the optically detectable character.
