ABSTRACT:
Stackable and portable data carriers, with non-volatile semiconductor memories have contact faces on their surfaces. When such data carriers are stacked on top of one another they electrically contact the respectively adjacent data carriers and a bus system at the same time. The contour of the data carriers is embodied such that, when neighboring data carriers of the same kind rest on one another, the data carrier are interlaced in a form and force lock to a mechanically fixed, but detachable composite unit. At the same time, the respectively adjacent data carriers of the composite unit come into resilient contact with one another via their respective contact faces.
