Provided is an information display medium that can enhance a forgery prevention effect. An information display medium (100) includes a light reflection layer (20) made of a metal or a metallic oxide and partially or fully placed on one surface of a substrate, and the light reflection layer (20) includes a first region (30) where first information is displayed by either of or a combination of an outline shape and a shape of an uneven region, and a second information display region (21a) where identification information formed by partial material removal of the light reflection layer (20), the second information display region being set to partially or fully overlap with the light reflection layer (20) where the first information is displayed in the first region (30).

A greeting card having a housing of metal or a metal alloy that defines an interior void and an electronic ink display screen, a Bluetooth adapter or dongle comprising Bluetooth low energy (BLE) technology within the interior void and operatively configured to communicate with the display screen, a non-transitory memory storage device, and another electronic component within the interior void. The Bluetooth adapter or dongle is configured to receive from an external electronic device a first communication of information describing an initial message to be displayed, and to receive, subsequent in time to receipt of the initial message, a second real time communication of information describing a second message. The non-transitory memory storage device has pre-loaded executable instructions to display the first communication on the display screen, to change or modify the initial message based on the second real-time communication, and to display the second message on the display screen.

A card-type medium includes: a card body; an internal component embedded in the card body; an exposed component partially exposed on a front surface of the card body; and a circuit board to which the internal component and the exposed component are bonded, wherein the circuit board includes a first connection portion to which the internal component is bonded, a second connection portion to which the exposed component is bonded, the second connection portion being located at a position different from the first connection portion in a card thickness direction connecting the front surface of the card body and a rear surface on an opposite side of the card body to the front surface, and a connection wiring portion that connects the first connection portion and the second connection portion, the connection wiring portion extending in a direction including the card thickness direction.

A package for an integrated circuit is marked with an encoded image (e.g., a two-dimensional barcode). The encoded image is scanned by a scanner to obtain manufacturing parameters. In one approach, a method includes: fabricating, in a manufacturing facility, a physical product using a manufacturing process, where the physical product is fabricated according to specifications, and the manufacturing process includes manufacturing steps performed in the manufacturing facility; marking the physical product with an encoded image, where the encoded image encodes parameters that include the specifications; and transporting the physical product to a storage facility, where the storage facility includes a scanner configured to scan the encoded image to obtain the parameters.

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.

In general, the subject matter described in this specification relates to security credentials for documents, such as identification documents. One example is an identification document that includes a photographic image of an individual associated with the document, and a spiral pattern applied to a region of the identification document. The spiral pattern includes an elliptical spiral segmented into a plurality of arc segments, where wherein the arc segments of the spiral pattern encode identification data associated with the individual. Other implementations include corresponding processes, systems, apparatus, and computer programs related to generating and verifying identification documents with spiral patterns.

A method for producing a hologram (1), (1) for security elements (1a) and/or security documents (1b). One or more virtual hologram planes (10) are arranged in front of and/or behind one or more virtual models (20) and/or one or more virtual hologram planes (10) are arranged such that they intersect one or more virtual models (20). One or more virtual light sources (30) are arranged on one or more partial regions of the surface (21) of one or more of the virtual models (20). One or more virtual electromagnetic fields (40) are calculated starting from at least one of the virtual light sources (30) in one or more zones (11) of the one or more virtual hologram planes (10). In the one or more zones (11), in each case, a virtual total electromagnetic field (41) is calculated on the basis of the sum of two or more, of the virtual electromagnetic fields (40) in the respective zone (11). One or more phase images (50) are calculated from the virtual total electromagnetic fields (41) in the one or more zones (11). A height profile (60) of the hologram (1) is calculated from the one or more phase images (50) and the height profile (60) of the hologram (1) is incorporated into a substrate (2) to provide the hologram (1).
