The Bus Ticketing System used on Singapore public buses is formally referred to as the New Onboard Bus Equipment, or simply NOBE.
The system was installed across all public buses by end-2013 and in use since 2014. Apart from governing fare collection via cash or contactless card, the NOBE provides commuters with real-time data on bus arrival times and the loading situation.
The NOBE comprises of three main subsystems: the Bus Fare Console, the Bus Card Validator and the Bus Locator System. The positioning systems is coupled with the distance-based fare structures to create a system that ensures the correct distance-based fare is collected for every fare, with minimum intervention from the operator of the bus (the driver), ensuring that the driver can fully concentrate on the road.
All transaction data are uploaded to the depots over-the-air when the buses return from their trips, the drivers can immediately proceed to the next job or their coffee breaks, and the enforcers can rest easy with no possibility of foul-play.
