TOTO (Tap on Tap Off) allows the customer to get the best value single fare by tapping your contactless card or mobile payment device on the card reader when they get on the bus, and by tapping off at the second card reader by the luggage rack as they leave the bus. Our ticket machines will know where the customer got on the bus and also where they got off, allowing them to charge you the best value fare automatically. TOTO is only available for single and day fares.
