Manual fare collection is the practice of collecting fares manually. "Fare collection" generally refers to the collection of fares in the transport industry in return for a ticket or passes to travel. Commonly used on buses and train transport systems, manual fare collection is increasingly becoming obsolete with the introduction of smart cards such as the Transport for London 'Oyster card'. However, in the face of this trend, some companies have opted to retain more traditional methods of manual fare collection to both save money and ensure reliability. In the United Kingdom, examples of this can be seen on the Transport for London Heritage lines and the FirstGroup FTR routes in York, Leeds, Luton, and Swansea where bus conductors have returned to work. The other reason(with lowering prices of electronics, and in most cases need to buy it once) may be for Heritage routes - tradition "look", for other routes(because of quite high monthly labor cost in UK) agreements and strong unions with the tries from politics to lower the unemployment rate by making overworking in public service.
