Apparatus for transferring data and other information between a data processing unit and a rectangular memory card which includes an optically readable data memory unit having a succession of substantially concentric data storage tracks thereon, the card also including at least one microelectronic component which stores further information. Such component is connected to connection points on the surface of the card. Data is read from the tracks of the memory unit by optical scanning during rotation of the card about the axis of symmetry of the memory unit, and information is transferred between the microelectronic component and the data processing unit by an information transfer unit which is coupled to the connection points on the card and to the data processing unit.
