An information system for vehicles (35) includes a plurality of contactless
transceivers (31-32) oriented in the direction of the passengers (36)
that allow a data transfer at close range, with a central data processor (2).
A data bus (3) is connected with the transceivers (31-32) and with
the central data processor (2), so that data can be transmitted between
private portable terminals (4) of the passengers and the central data processor
(2) in both directions over the transceivers (31-32) and the data
bus (3). The portable terminals (4) additionally store passengers'
identification data in such a manner that the identification data are transmitted
to the central data processor, so that the system can check the passengers' travel authorizations.
