Abstract: The booklet comprises a number of sheets between a cover, and each sheet has a front side and a rear side. At least one data page is provided that is joined to the cover in a fixed manner. The data page comprises a flexible layer and this flexible layer projects with an area out of a data carrier. On this area, the data page is joined to the cover and to the remaining sheets. The flexible layer is flatly joined to at least one other layer, for example, by welding or bonding and is thus inseparably bound without a mechanical joining part.

Abstract: In order to produce a data carrier, a substrate is printed with a printing ink and personalized by means of a laser. The printing ink is laser-active and is converted at least in regions during the personalization in such a way that, for example, a silver-grade pigment is formed which is readily visible only when the substrate is inclined. In particular, the printing ink has a comparatively small proportion of carbon black that is converted by the laser essentially without disturbing combustion and overall formation.

Abstract: For producing a card-type data carrier, an electronic module is inserted into a cutout of a semifinished product having at least one film. The cutout is produced such that an interspace remains between the periphery of the module and the cutout after the module has been inserted into the cutout. After the module has been inserted into the cutout, the at least one film is locally heated and densified around the module such that the at least one film closes the interspace. The film is preferably heated by means of a stamp, in particular of a sonotrode.
