First Claim
1. A portable element for receiving, storing, displaying and outputting digital data, said portable element having data input, a memory having an at least partly modifiable content, a display device for the persistent display of digital data in the form of characters on the basis of data received on the data input, and a data output, for use in a reservation system having at least one locally present reservation device and at least one service facility which is not locally present, characterized in that:
- means to couple said data input and data output for coupling to an access device of the reservation device and for then receiving a proximity signal from the reservation device;
means to transmit, co-controlled by said proximity signal, identification data stored in said memory and a reservation request concerning the service facility to the reservation device in order to grant the reservation request;
means to unblock said system by a verification signal generated by said identification data after examination thereof in the reservation device;
said display device having means to display, under the control of the content of the memory modified by a signal of availability data from the reservation device, reservation data concerning a reservation of a service facility, the availability data in the reservation device being adapted at the same time.

Abstract
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.
