Abstract
Abstract The present invention relates to a data carrier having an integrated circuit and to a method for making the same. During production a carrier element equipped with an integrated circuit and contact surfaces is inserted into a recess in the data carrier blank. To allow for the carrier element to be fixed in the recess, said element is underlaid with a melt adhesive film. To protect the integrated circuit from mechanical stresses, a film strip made of a material with high elastic deformability is provided additionally between the circuit and the melt adhesive film.
