Abstract: A system for detecting customer media comprising an RF transceiver in a public transport conveyance is proposed, where the system for each passenger compartment or car includes a number of reading devices, which are interconnected and connected to an on-board unit for the purpose of data communication, where the entire interior of passenger compartment or car is covered by a number of reading devices, where the reading devices are arranged in such a manner that any two reading devices are provided on opposite lateral walls of the passenger compartment or car, which cover the room up to the opposite wall, where each two reading units are arranged in the roof area or floor area symmetrically around the central longitudinal axis of the passenger compartment or vehicle, where the detection range of the respective two reading devices is substantially identical and substantially covers the entire width of the passenger compartment or car in the floor area or roof area, where the floor area or the roof area is cover

Abstract: A method for continuous determination of a person's presence in a public transport conveyance is proposed, where a customer medium comprising an RF transceiver is assigned to the person, where at least one reading device per passenger compartment or car is provided for data communication with the customer media in the conveyance, which is connected to a computer serving as an on-board unit for the purpose of data communications, where these are also connected to each other in the case that several reading devices are provided, where an on-board unit serving as the main on-board unit is assigned to a passenger compartment or car if several passenger compartments or cars are present, and the other passenger compartments or cars are assigned to on-board units serving as secondary on-board units, which are connected to the main on-board unit for the purpose of data communication, where the customer medium is in a “sleep” mode upon entering the transport in order to keep energy consumption as low as possible.
