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 display member includes: a surface which is an observation object; a first image pattern which is covered by the surface and displays, through the surface, a first image including one or more first information elements for identifying an owner of the display member; a second image pattern which is covered by the surface and in which one or more second information elements are embedded, a part of the second image pattern restricting identification of the one or more second information elements, the second image pattern including a second image that differs from the first image and is for identifying the owner of the display member; and a concealment pattern that is located between the second image pattern and the surface and removes the restriction on identification of the one or more second information elements by concealing the part of the second image pattern.

A security device is disclosed, comprising an array of focussing elements with regular periodicity in at least a first direction, each focusing element having an optical footprint of which different portions will be directed to the viewer in dependence on the viewing angle; and an array of image elements with regular periodicity in at least the first direction overlapping the array of focusing structures, the image elements representing portions of at least two respective images, and at least one image element from each respective image being located in the optical footprint of each focusing structure. The security device includes a first region and a second region which is laterally offset from the first, the image elements in the first region being laterally shifted in at least the first direction relative to the image elements in the second region such that, at a first viewing angle, in the first region of the device the focussing structures direct image elements corresponding to a first image to the viewer such that the first image is displayed across the first region of the device, and simultaneously, in the second region of the device, the focussing structures direct image elements corresponding to a second image to the viewer such that the second image is displayed across the second region of the device, and at a second viewing angle the second image is displayed across the first region of the device and simultaneously the first image is displayed across the second region of the device. The security device further comprises a colour filter located in use between the image elements and the viewer, the colour filter overlapping at least part of the array of focussing elements and the array of image elements, and having a first colour in the first region of the device and a different colour in the second region of the device such that the colour appearance of the first and second images is different in the respective first and second regions of the device.

A method for applying a transfer ply of a foil to a substrate, with the steps of: a) regionally applying a radically curable adhesive to the transfer ply and/or the substrate by means of an inkjet printhead; b) precuring the adhesive by UV irradiation; c) applying the transfer ply to the substrate by means of a stamping apparatus; d) fully curing the adhesive by UV irradiation; e) peeling a carrier ply of the foil, to leave at least one first subregion of the transfer ply on an application region of the substrate, and at least one second subregion of the transfer ply on the carrier ply; f) winding up or recoiling the carrier ply with the remaining second subregion of the transfer ply; g) applying at least one further subregion of the transfer ply remaining on the carrier ply to the substrate by at least once repeating steps a) to f).
