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.
