发明名称 IDENTITÄTSKARTE UND REISEDOKUMENT
摘要 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.
