Identity card and travel document
An identity card that can be used, for example, in a travel document or as a separate card, includes at least two core layers, preferably of polycarbonate material, that are fused to one another. In each of the core layers there is a recess, each of a different size. On assembly these recesses become situated on top of one another and a semiconductor chip is accommodated in the larger recess formed as a result. A covering layer can be fused to at least one of the core layers, and a layer that can be written on by laser can also be applied. There can be (semi-)transparent windows on top of one another in the core layer and if the covering layer is transparent, light can be transmitted, it being possible to define a specific pattern in the windows.
1. An identity card comprising:
first and second core layers of plastic material fused together, wherein said first core layer has an accommodation;
a semiconductor chip which extends in said accommodation;
an antenna connected to said chip being arranged between said fused core layers and extends around the periphery thereof, wherein each core layer has a thickness of between 50 and 600 μm, said accommodation comprises a recess and said second core layer is provided with a recess, said recesses being above one another in the assembled position and having different dimensions;
a covering layer arranged on said first core layer and another covering layer applied to said second core layer; and
a layer being provided between said covering layer and said second core layer that can be written on by laser light.
2. The identity card of claim 1 , wherein said layer that can be written on by laser light comprises a separate layer that is arranged between said covering layer and said first core layer and can be fused therewith.
3. The identity card of claim 1 , wherein said covering layer is transparent.
4. The identity card of claim 1 , wherein at least one of said layers comprises polycarbonate.
5. The identity card of claim 1 , wherein transparent windows are arranged in said first and second core layers, which windows are on top of one another in the assembled state.
6. The identity card of claim 5 , wherein said windows are clear.
7. The identity card of claim 5 , wherein said windows are provided in a semi-transparent pattern.
8. The identity card of claim 1 , containing biometric characteristics of the bearer.
9. The identity card of claim 8 , containing a raster photograph.
10. The identity card of claim 8 , containing iris information.
11. The identity card of claim 8 , containing fingerprint information.
12. The identity card of claim 8 , containing face information.
13. A travel document comprising a booklet provided with pages, with a lip protruding from a spine to which an identity card is fixed, said identity card comprising:
first and second core layers of plastic material fused together, wherein said first core layer has an accommodation;
a semiconductor chip which extends in said accommodation;
an antenna connected to said chip being arranged between said fused core layers and extends around the periphery thereof, wherein each core layer has a thickness of between 50 and 600 μm, said accommodation comprises a recess and said second core layer is provided with a recess, said recesses being above one another in the assembled position and having different dimensions;
a covering layer arranged on said first core layer and another covering layer applied to said second core layer; and
a layer being provided between said covering layer and said second core layer that can be written on by laser light.
14. The travel document of claim 13 , wherein said fixing comprises a pattern of holes made in said lip and a closing strip fitted through said pattern of holes and fused with said identity card.
