A security-enhanced document including a substrate, variable indica applied to an area of a first side of the substrate, a scratch-off-coating applied over the variable indicia to maintain the variable indicia unreadable until the scratch-off-coating is removed by being scratched off, and digital imaging applied to an area of a reverse side of the substrate from the variable indicia, wherein the digital imaging applied to the area of the reverse side of the substrate includes the same materials as the variable indicia, is uniformly spread over the area of the reverse side of the substrate, and such that the digital imaging overlaps at least 50% of the variable indica applied to the area of the first side of the substrate, such that the variable indicia exhibits an insufficient signal-to-noise ratio relative to the signal-to-noise ratio of the digital imaging on the reverse side of the substrate so that the variable indicia cannot be discerned so long as the scratch-off-coating remains intact.

The present invention is directed at a method for manufacturing a card-shaped data carrier, in which a material from nature, for example wood, is installed in a particularly advantageous manner. The invention is further directed at a correspondingly adapted apparatus for manufacturing the card-shaped data carrier as well as at the data carrier itself. Further, a computer program product is proposed, having control commands that implement the method and/or operate the proposed apparatus.

A security-enhanced document includes a substrate and variable indicia comprising ink having a signal. The variable indicia is of a specific type and is applied to the substrate using a specific application technique. At least one other printed portion, which is a back of the document, has background ink noise, and the type of ink of the back of the document is of the same type of ink applied to the substrate using the same application technique as the ink of the variable indicia. The document also includes a scratch-off-coating applied over the variable indicia. The document has a signal-to-noise ratio of the ink of the variable indicia relative to the background ink noise of the back of the document that is not appreciable, thereby making the variable indicia unreadable with reference to the back of the document when the scratch-off-coating remains intact.

A method of printing a digital image includes printing authentication marks by applying an amplitude modulated raster print in a detection zone to an object, the printed area of the detection zone consisting of asymmetric raster dots, wherein at least two mutually non-parallel finder edges are printed from at least one finder zone to determine the position, boundary and orientation of the detection zone. A method of authenticating such a print includes capturing an image of the printed article; detecting the at least two finder edges to determine the detection zone from the image with halftone dot accuracy, comparing the captured print image of the detection zone with the resulting print images, and deciding on the basis of the comparison whether there is an original print on the article.

A gift card carrier for holding a gift card includes a first part having a first portion and a second portion that is formed of a transparent plastic material and includes a pair of gift card slits for releasably retaining the gift card. The gift card carrier also has a second part that has an open interior space. The second portion of the first part is sized to carry the gift card and be received within the open interior space of the second part. The first part moves between a fully retracted position in which the second portion is received within the open interior space and an extended position in which the second portion is exposed for removal of the gift card.

A physical device for safely and securely storing a seed phrase of a crypto wallet or like cryptographic services. The device having cover plates that can sandwich several grid plates, wherein the cover plates and the grid plates are swively bind together using a fastener. Each grid plate is having a grid of columns and rows. Each column is having several sub-columns. Each sub-column having ten rows for the numeral sequence 0-9. Each word of the seed phrase in its corresponding numerical code can be encoded on the grid.
