The invention relates to a chip card with at least one application for which an implementation and an entry referring to the implementation are present on the chip card. Collimators are mounted directly opposite one another on the organs, in an arrangement such that they permanently provide a variation of the power of the transmitted signal of less than 25%, during relative rotation of the said organs. The membrane shells are connected along a circumferential seam such that the pulsation damping capsule can compress and expand in a resilient-elastic manner as an energy convertor when subjected to external pressure as a result of pressure medium pulses. A plurality of trucks extend between the circular tracks, the trucks having at least two grooved rollers which partially surround the circular tracks and operate in rolling engagement therewith. The associated content handler is requested using the reference, the reference including a reference location for the content handler.
