Very used to getting a one day travelcard for travelling around London as a tourist.
But I am aware that people do just use their contact less card to pay and it will never charge you more than the equivelent travel card?
Is it that simple? Just use your contactless card to enter and exit and once you've reached the same cost as the travelcard, it won't charge more?
And you could potentially pay less?
Does it work on the bus as well?
