Abstract

A carrier card of standardized size has a base body with at least one cutout for receiving a value chip. The cutout has securing elements forming a snap connection for detachably securing the value chip. The cutout is positioned such on the base body of the carrier card that the value chip in the cutout is usable with standardized application devices. The value chip is removable so as to be used as a minichip card with processing devices that are smaller than the application devices. The cutout has wave-shaped edges with alternating projections and depressions. The base body has a bore for each one of the projections, wherein each one of the bores is arranged perpendicular to the respective projection such that an elastic stay is formed. A cover foil is connected to one face of the base body so as to cover the cutout. At least one of the wave-shaped edges is undercut such that the cutout widens toward the cover foil.
