TOTO (Tap On, Tap Off) contactless

Tap On, Tap Off is one of several names given to a type of Contactless Model 2 payment method. It allows you to simply “tap” your contactless payment card (or device) onto a reader at the start of your journey and “tap” again on a reader when you complete your journey. What you are charged for the journey is calculated later and then automatically from your account. Often this charge will be capped at a maximum amount if enough journeys are taken within a specific period of time, e.g. 24 hours.

This is different to Contactless Model 1 where the products you are buying are totalled up by the cashier, or a self-service machine, and you pay the total on the screen with your contactless payment card. If you want to buy a specific ticket on a bus or tram in the UK, you will use Contactless Model 1.
