Using the Oyster Card
The Oyster Card is not stamped with a start or expiry date which means you can start using your Oyster Card whenever you want and any remaining credit can be used during any future trips to London. You can also easily top up your Oyster Card with cash or card at any TFL ticket counter. And don't worry, using your Oyster Travelcard for the first time won't activate your London Pass.
