How do I register my Contactless Mobile details with Transport for London (TfL)?

Head to the TfL website and sign up for a ‘TfL Online Account’ using your Contactless Mobile account details. This will allow you to track the journeys you’ve paid for with Contactless Mobile. 

To find your Contactless Mobile account details, open Barclays Mobile Banking, go to ‘Contactless Mobile’ and then ‘Account details’. There, you’ll find your 16-digit Contactless Mobile account number, your expiry date and your CVV.
