An improved data bearing card includes a card body, personalization data unique to the data bearing card, and non-visible production indicia, separate from the personalization data, disposed on the card body and indicative of production-related information not otherwise provided on the data bearing card. The non-visible production indicia may be indicative of a corresponding piece of production equipment and/or an operator thereof utilized in connection with the data bearing card, or of a location of a corresponding region of a sheet assembly from which the corresponding card body was separated during production, or of other production-related information. The non-visible production indicia facilitates remedial action in the event that a defect or near-defect is found in the card body or other components of the data bearing card, and may otherwise facilitate card tracking during the production process.

Provided are: a light diffraction layer laminated sheet which enables easy production of a card that has a light analysis structure; and a card. A light diffraction layer laminated sheet material which forms a part of a laminated structure of a card by being laminated on top of a card base material. This light diffraction layer laminated sheet material is provided with: a transparent sheet layer; a hologram layer that has a contour smaller than the contour of the transparent sheet layer and is laminated on one surface, which is the upper surface, of the transparent sheet layer; and an HS layer that bonds the transparent sheet layer and the hologram layer with each other.

A method of forming a polymer substrate for a security sheet includes: providing first and second overlapping polymer layers each providing outwardly facing surfaces, and a colour shifting element positioned between the first and second polymer layers adapted to provide a first optical effect to a viewer, wherein the first polymer layer includes a region substantially transparent to visible light such that the colour shifting element is viewable through the first polymer layer, and; joining together the first and second polymer layers in order to generate a polymer substrate wherein, during the joining step, a surface relief is formed in the outwardly facing surface of the first layer, the surface relief being adapted to interact with light from the colour shifting element in order to modify the first optical effect to provide a second optical effect different from the first optical effect.

A card manufacturing system includes a locating device and a separation device. The locating device is configured to identify a position of one or more information carrying cards formed integrally with a laminate sheet and generate information corresponding to the position of the one or more information carrying cards. The separation device includes at least one singulation mechanism configured to separate each of the one or more information carrying cards from the laminate sheet. The singulation mechanism separates the one or more information cards based on the information corresponding to the position of the one or more information carrying cards.
