Abstract: A fare box has two separate chambers connected together by a connecting opening, with a fare receiving module in one of the chambers for receiving deposited fares and transporting them to the connecting opening, and a cashbox in the other chamber for receiving fares deposited in the connecting opening. A locking device is associated with the fare receiving module for releasably retaining it in the first chamber, and a security shutter in the housing is moveable between a first position blocking the connecting opening and a second position in which the opening is unblocked. The security shutter and locking device are linked together so that the connecting opening is blocked whenever the fare receiving module is released.
