What happens if I touch in with one contactless card, and touch out with another on the same journey?

It's important that you try to avoid doing this, as you'll be charged a maximum fare on both of your cards. The two separate journeys won't be linked and each one will be recognised as incomplete. If this happens, please get in touch with Transport for London (TfL) Customer Services on 0343 222 1234*.

If you’ve more than one contactless card (which includes your Oyster card, Barclays debit card, Barclaycard and any other contactless card) we recommend that you keep them separate to avoid card clash. If you'd like to find out more about maximum fares, just go to tfl.gov.uk/contactless.

*Call charges apply, please visit tfl.gov.uk/callcharges for details.
