A carrier element in card form has at least one integrated semiconductor circuit disposed on the carrier element. External terminals of the data carrier card have a terminal surface disposed on an edge surface of the carrier element. Further terminal surfaces are preferably provided on main surface areas of the carrier element for an external terminal. If a plurality of data carrier cards are laid congruently one on top of the other, an electrical connection between the external terminals of the respective data carrier cards is established in a simple way.

Data carrier card, assembly of at least two data carrier cards and

Portable data carrier configurations with non-volatile semiconductor memories serve as rapid-access storage media for data processing systems. It is possible for a multiplicity of such data carrier configurations to be operated on a bus system. The data carrier configurations preferably contain a microprocessor which, for example, automatically creates an index file of files stored in the data carrier configuration and also searches for certain terms and actively or passively reports a search result on request from a PC or a microprocessor provided in a receiving adapter for the data carrier configurations.
