Abstract

A forgery-proof information carrier comprises an insert (1) having a passport photo (7), data about the owner and other security features, and plastics films (5, 6) which are joined in an undetachable manner to the insert (1), and is distinguished in that a metal mask (2) is provided as an edge protection at least in the region of the edges of the information carrier. In a further development to increase the security against forgeries, the metal mask (2) may be inwardly provided with irregular edges (3) or with openings (4).

Claims

1. In a forgery-proof multilayer information carrier comprising the combination of

an insert sheet,

means on said sheet for providing information,

a metal mask member juxtaposed with said sheet to adjoin and surround the periphery of said sheet;

and a pair of layers comprised of plastic films

each of said layers being bonded to one of the planar surfaces of said sheet and of said juxtaposed mask member

whereby said sheet and mask member are interpositioned between said layers

said card being so constructed and arranged that the card is provided rigidity and strength.

2. An information carrier according to claim 1, characterised in that the metal mask terminates outwardly in a flush manner with the edges of the information carrier and has jagged or irregularly formed inside edges.

3. An information carrier according to claim 1, characterised in that the metal mask is provided with openings, through which a top plastics film is joined to a bottom plastics film by bonding or welding.

4. An information carrier according to claim 1, characterised in that the metal mask has a thickness corresponding to that of the insert sheet and it joins the periphery of the insert sheet in an exactly fitting manner.

5. An information carrier according to claim 1, characterised in that the metal mask is thinner than the insert sheet, covers the periphery of the insert and is joined to the insert and/or is imprinted therein.

6. In an information carrier

comprising a pair of plastic films bonded together and an information carrying member interpositioned between the bonded together films

the combination of

an insert sheet penetrable under pressure,

means on said sheet for providing information

a metal mask member interposed between said films

and having an edge inward of said card defining an aperture into which said sheet is juxtaposed so that the mask surrounds the sheet,

teeth on said inward edge penetrating said adjoining sheet,

and a layer composed of a plastic film attached on each side of said combination whereby the sheet and mask member are joined in an undetachable manner to the plastic films.
