Abstract: A travel registration arrangement including a travel pass unit for general communication, e.g. by train, by air, by sea, by bus. The unit (15) includes a processor, a write and erasable memory unit connected to the processor, a display window (2) and keys that can be manipulated by a traveller provided with the travel pass. The system includes a station (10) for issuing the travel pass unit. A traveller who wishes to obtain a travel pass is registered in the station together with a code number which is unique to the unit (15) and which is written into a fixed memory. Data relating to the traveller is written into the writable memory unit of the travel pass and, on the occasion of issue, possibly also data relating to the journey or route concerned. Data relating to the issued travel pass is stored in a data base (11), together with information relating to the journey or route concerned. A plurality of terminals (17-20) which include travel pass unit readers/writers are connected to the data base (11).
