This disclosure includes a method for manufacturing a portable data carrier, an inlay for a data carrier, and a data carrier. A data carrier body has a gap for a chip and a chip is incorporated into the gap. In a subsequent step a cover layer is laid on the data carrier body, and the data carrier body and the cover layer are laminated. After the incorporation of the chip and before the lamination, a stabilizing agent is applied into the gap of the core layer, which remains soft or flexible during the lamination and cures or is activated (e.g. by means of UV radiation) only after the lamination, in order for mechanical tensions to be avoided.

Method for producing a data carrier that prevents mechanical strains between chip and data carrier body

A method for producing a data storage medium body for a portable data storage medium having a core layer and at least one top layer, wherein the core layer contains a chip module. The chip module has a surface which is adverse to lamination and has an adhesive deposit applied on the module surface; a recess is provided in the core layer and the chip module is inserted into the recess such that the module surface having the adhesive deposit is situated towards the open side of the recess; a top layer is applied over the module surface; then the above arrangement is laminated. The adhesive deposit combines intimately with the adjoining top layer.
