You can tap on and off Transdev and be charged the relevant daily rate or sum of fares, whichever is cheaper. However, the rollout was very extended, with Burnley getting it much later than other places.Did anything ever come out of that tap on tap off thing they made a big deal about a few years ago? Looking back on it I saw them announce it then never saw or heard about it again as if it never existed.
I haven't used it, as I usually know which ticket I'll need for a day, or I'll need a multi-operator one, which hasn't happened in West Yorkshire yet, despite noises a couple of years ago.
