Portable element for receiving, storing, displaying and outputting digital data, and a reservation device for use in a reservation system










Image Number 4 for United States Patent #4298793.

A portable element shaped as a card, for receiving, storing, displaying and outputting data in numerical or alphanumerical characters, for temporarily communicating with a locally present reservation system and to exchange data therewith. The reservation system communicates with a service facility which is not locally present such as a transport vehicle. On the basis of an actual or forecast staus of the service facility, reservation data are applied to the portable element, and are displayed thereon, and also applied to the service facility. The contactless communication between portable element and reservation device can be initiated by a proximity signal.
