Abstract: An insertable device, for use with electronic data processing equipment storage units, e.g., disk drives or cassette units. The device includes a housing for insertion at least partially into the storage unit of a size and shape designed to fit the storage unit, an interface disposed in the housing for facilitating the transfer of data between the device and the electronic data processing equipment, and a processor disposed in the housing and operatively connected to the interface, for performing processing of data.

Abstract: A data storage system includes a data read/write device which can be incorporated in electronic data processing (EDP) devices with the external shape of an 88.9 mm (31/2 inch) diskette drive, which contains a read/write head and a controller, which transacts the protocol to write and read and is connected with a processor of the EDP device, and further includes a data carrier constructed as a smart-diskette in the shape and the dimensions of a 88.9 mm (31/2 inch) diskette which can be inserted into the data read/write device. The data carrier has electronic components, including controller, microprocessor and memory as well as a stationary magnetic transducer which is firmly connected with the data carrier. Data transfers are carried out through and between the read/write head and the stationary magnetic transducer. The data read/write device has no moving parts at all, i.e.

Abstract: Operating procedure and device for the electronically authorized determination of an individual matter and for obtaining, in a reliably differentiating manner which is secure against forgery, the remotely authorized, individual authentication of a transaction requiring an authentication from an authorized person. The entire system is composed of two hardware components, an AIDA box which can be a pocket calculator equipped with special function keys, and an AIDA module which is a dual processor system with insertable AIDA cards containing special chips. By putting a personal identification number into the AIDA box and through the intermediary physical action on the chip, an identification number is calculated with the aid of an algorithm and displayed. An electronic signature is calculated and displayed by putting in the information to be authenticated. After transmission over a communications system, the calculated values are checked in the AIDA module.
