I've recently bought myself an Oyster Card.
I only go to London occasionally to have a day out and I used to buy a
One Day Travel Card.

Now that I have an Oyster Card, I was wondering how the "Price Capping"
works
on the card?

Does it charge me for EVERY journey I make on London Transport or does it
charge me
up to the current price of a One Day Travel Card and then no more?

Thanks.
