Abstract: A method and a system (1) for electronically registering the use of a public transport facility (3), such as a bus, a train, a tram, the underground, a taxi or the like. The passenger is equipped with a wireless communication device (7, 8) carrying identity data (9), which is suitable for communication with a local communication infrastructure (2) associated with a respective public transport facility (3). The local communication infrastructure (2 ) is arranged for automatically registering the identity data of the communication device (7, 8) upon commencement of the transport automatically registering the identity data of the communication device (7, 8) upon termination of the transport, automatically registering further data relating to the distance travelled and the time between the two identity data registrations and exchanging the registered data with remote processing equipment (5).
