An authentication system includes an object including an authentication hologram disposed over an area of a surface of the object. The authentication hologram is defined by a pattern of reflective material and includes latent authentication information. The system includes a computer-readable medium including program instructions for execution by one or more processors. The program instructions are executable by the one or more processors to: (i) receive, from an image capture device, a digital image of the authentication hologram, wherein light reflected by the reflective material is captured in the digital image of the authentication hologram, and (ii) detect the latent authentication information in the digital image of the authentication hologram, wherein an effect of the reflected light is reduced to detect the latent authentication information.

A method for manufacturing a portable data carrier by means of a continuous manufacturing method, comprises the steps: providing at least one foil as a rolled good, unrolling at least one first foil, with at least a first foil being coated at least partly with an adhesive on at least one side, with at least the first foil being scored on at least one side along at least one creasing edge, with at least the first foil being folded up in precise fit along at least one creasing edge and bonded, with the foil being folded up in the direction of the side which is coated with adhesive, with the side coated with adhesive being arranged on the opposite side of the foil which has at least one scored creasing edge along which it is folded.

A device for recording information in a data carrier, comprising a data carrier receptacle for partially receiving the data carrier in a planar manner; a data carrier cover arranged relative to the data carrier receptacle, which is designed for holding the data carrier between the data carrier receptacle and the data carrier cover; a laser source for the controlled emission of a laser beam designed to effect irreversible changes of the data carrier with the laser beam; and a mount that receives the data carrier receptacle to be pivotable about a pivot axis. The data carrier receptacle has two or more positions, that allow the data carrier receptacle to be received in the mount in such a way that the data carrier receptacle can be repositioned about the pivot axis in a pivotable manner.

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.

A stamping kit is disclosed. The stamping kit includes a jig, a card, and a plurality of stamps. The jig includes an upper surface, a lower surface, a front surface, a rear surface, a card slot, and a stamping slot. The card slot extends between he front surface and the rear surface, and defines a width and a height. The stamping slot extends between the upper surface and the card slot, and defines a width and a length. The card defines a width and a thickness, and is configured to slide within the card slot of the jig. Each stamp of the plurality of stamps has a proximal end configured to be engaged by a hammer, and a distal end having a character thereon. A distal portion of each stamp is configured and dimensioned to enter the stamping slot of the jig.

The security document, such as a passport, comprises a lightguide having an incoupler structure and in outcoupler structure. The outcoupler structure is sparse in the sense that any part of the protective area is close to a part of the outcoupler structure. However, to secure a large protective area with a limited amount of incoupled light, outcoupler structure covers no more than 20% of the protective area. This allows to protect a large area of the security document, such as a photograph or other personalized information, by means of the lightguide.

A children's book includes pages having text in a first orientation and pages in a second orientation, the first and second orientation related by being upside down relative to each other. As a child reads the book from a first end, the child encounters up a page with writing in both orientations, instructing him to turn the book upside down, close, and re-open the book. As the child re-opens the book that was turned upside down, the story continues from the opposite end of the book.

The invention relates to a marking composition, by means of which better protection of goods than hitherto available can be achieved independently of the coloring of the goods. The marking composition comprises an infrared-absorbing particulate component and carbon derivative, wherein the weight ratio of infrared-absorbing component to carbon derivative is in the range of approx. 10:1 to approx. 10,000:1.
