Abstract: Write-read unit in the form of a compact hybrid drive for combination or alternative use of plugable, removable, encapsulated flat modules equipped with semiconductors (IC cards) and with one or several drives for rotating storage media, such as drives for floppy disks, hard disks, compact disks as well as magneto-optic drives to be connected to electronic devices, such as electronic data processing machines, printers or controls. The selection of the write-read unit is effected via an integrated electronics either joint or separate for the storage media. Existing electronic devices can be extended without requiring additional space in order to shift complex data processing transactions onto the IC card, thus relieving the central processing unit.

Abstract: An IC card adapter is connectable to an electronic device such as a computer or printer. The adapter removably stores a plurality of IC cards which are connected to the electronic device through a connector portion. The adapter has a housing with three slots each having a card receptor portion. A first slot on the rear side of the housing is larger than the other two slots on opposed sides of the housing. This first slot and card receptor portion are located closer to the bottom of the housing than the other two slots and card receptor portions. Indicators and a phone connection device can also be provided on the housing and a printed circuit board with electronic mechanisms can be provided within the housing so that the adapter can operate without the IC cards.
