Ascom B8050, usually known by the name QuickFare, is an early example of a passenger-operated railway ticket issuing system, consisting of a series of broadly identical machines installed at British railway stations from 1989 onwards. The machines allow passengers to buy the most popular types of ticket themselves, without having to go to a booking office, and are therefore useful at unstaffed, partly staffed or busy stations. All QuickFare machines have been replaced by more modern technology.
