Abstract: A document, product, or package, such as a banknote, passport or the like comprises structures having dichroic effects that change color with viewing angle in both transmission and reflection. Such structures can be useful as security features that counter the ability to effectively use counterfeit documents, products, packages, etc.

Abstract: A data carrier comprises at least one substrate layer and at least one processing layer. The substrate layer and the processing layer are arranged at least partially above one another with respect to an extension direction. The substrate layer is at least regionally transparent. The processing layer comprises pigments that are configured to change an appearance, in particular a translucency and/or an opacity and/or a glossiness and/or a colour, upon an irradiation of electromagnetic radiation.

Abstract: An IR and/or UV machine-readable optical security device (e.g., micro-optic security thread) that is made up of at least one IR-absorbing component with a characteristic IR signature detectable at two or more IR-wavelengths, at least one UV-absorbing component with a characteristic UV signature detectable at two or more UV-wavelengths, at least one IR-absorbing component that absorbs IR light and emits light at a different invisible wavelength, at least one UV-absorbing component that absorbs UV light and emits light at a different invisible wavelength, or a combination thereof, is provided. The IR and UV machine-readable features do not interfere with the optical effects projected by the optical material.

Abstract: An identification medium includes a first layer, and a second layer disposed thereon in a manner of overlapping with the first layer. The first layer is capable of reflecting one of clockwise circular polarized light and counterclockwise circular polarized light and allowing to pass therethrough the remaining circular polarized light. The second layer is capable of reflecting at least a portion of circular polarized light having the same rotation direction as that of the circular polarized light that the first layer reflects, and allowing to pass therethrough circular polarized light having an opposite rotation direction to that of the circular polarized light reflected by the first layer. A ratio (Ssf2/S2) of Ssf2 defined by the following formula (2) relative to S2 defined by the following formula (1) is more than 0.7:

Abstract: A structure for secure containment of information (SSCI) that is in the form of a laminate which includes at least two layers. The laminate is constructed to contain information such as a code, serial number, informational feature, encryption key or personal identification number (PIN). The information is located between the layer of the laminate such that the code, serial number, informational feature, encryption key, or PIN is not detectable from outside the laminate. The SSCI is configured to provide access and expose the code, serial number, informational feature, encryption key, or PIN by delaminating at least one layer, thereby indicating that tampering has occurred to the laminate. The SSCI can also function as a public key or private key for a blockchain, to provide access to a physical lock or to provide account access to claim financial value.

Abstract: Disclosed embodiments pertain to a payment card with an integrated door. A top layer can be affixed to a bottom semirigid layer. The top layer can include a first portion attached to the front face of the bottom layer and a second portion, or door, coupled to the first portion in a manner that allows the second portion to rotate to and from an open position and closed position. The bottom layer can include a cardholder name, account number, expiration date, and security code hidden from view when the door is in the closed position. A fastener can also be added to secure the door in an open position, closed position, or both. In one embodiment, the payment card can include an antenna for contactless transactions, and the door's position can control the antenna's availability for wireless communication.

Abstract: 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.

Abstract: A security note may include a first transparent substrate having an area that defines boundaries of the security note. The note may include a first base layer deposited on the first transparent substrate. The note may include a second base layer deposited on the first base layer. The note may include a second transparent substrate formed on the second base layer. One or more security features may be provided between the first base layer and the second base layer. One or both of the first base layer and the second base layer may define an opening within the area of the first transparent surface such that at least one of the one or more security features is visible via the opening.
