A display device includes an electronic paper display and a ground electrode. The electronic paper display is imageable by receiving charges on a charge receiving layer of the electronic paper display. The ground electrode is opposite to the charge receiving layer of the electronic paper display and exposed at an edge of the display device.

A protective document cover is disclosed. The protective document cover includes a clear protective sheet that may be affixed to the front and/or back surface of a document, such as a vaccination card, via an adhesive. Micro-perforations in the sheet define one or more non-adhesive tear away covers that are dimensioned and positioned to overly updateable field(s) of the document to allow the tear away cover(s) to be removed from the protective cover and document and allow updating of the field(s) on the document. Removal of the tear away cover(s) allow a healthcare provider to record additional information to update the card. Pressure sensitive replacement covers, with permanent adhesive, of the same size as the tear away covers are provided to permanently protect the areas where additional information has been recorded. The protective replacement cover(s), once applied to the card provide permanent protection to the updated area of the card.

A security paper for manufacturing value documents has a planar substrate equipped on one surface with an anti-forgery means based on a carrier foil having an optically variable security feature. The anti-forgery means and a partial substrate area surrounding the anti-forgery means is furnished with a dirt-repellent radiation-curing first lacquer substantially not influencing the perceptibility of the optically variable security feature. The layer thickness of the lacquer lying is in a range of 0.7 to 2 micrometers. The radiation-curing first lacquer is may be a UV-cross-linking lacquer which after cross-linking is high-gloss. The substrate can be furnished on its surface lying outside the anti-forgery means with a dirt-repellent second lacquer and optionally partly overlaps the first lacquer in the region of the partial substrate area surrounding the anti-forgery means. The second lacquer involves either a physically drying, water-based dispersion lacquer, or a UV-cross-linking lacquer, and has a matt impression.

The inventor here discloses destructive (self-destructing) documents useful for the protection of confidential information. The invention comprises a document which can be easily and instantly broken down into dozens of individual components, hence obliterating any information contained thereon. As the self-destruction of the document requires no extraneous equipment for destruction and guarantees elimination of readable data, the invention represents a vast improvement over the state of the art. Numerous embodiments of the document of the invention specialized for different applications are illustrated and described.

Aspects described herein may allow for a payment card assembly including a payment card having a first surface, an opposed second surface, and an aperture extending through the payment card from the first surface to the second surface. An insert may be removably received in the aperture. Each of a plurality of identification elements may be configured to be removably received in the aperture and have an identification characteristic different than an identification characteristic of each of the other identification elements.

A manufacturing assembly for the creation of laminate constructions includes a calendar device arranged to accept a laminate of three or more layers of material stock, as provided by a matching three or more rolls of the material stock. A sheeting device is arranged downstream from the calendar device for cutting the laminate into predetermined sizes, such that the laminate is kept in a non-rolled, planar orientation subsequent to the laminate exiting the calendar and before the laminate is sheeted by the sheeting device.

Herein is described a scratch-off structure comprising the following layers in order: a substrate having a first layer showing information thereon, a second layer comprising a polymeric film and being substantially transparent; a third layer comprising a transparent electrostatic ink; a fourth layer, wherein the fourth layer is coloured. Methods for making scratch-off structures and collections of scratch-off structures are also described.
