We recommend that you set up a TfL online account and register your Contactless Mobile account. This gives you access to added benefits, plus you'll be able to see up to 12 months of journey and payment history. If you don't register your Contactless Mobile account, you'll only be able to view seven days’ worth of journey history.
You can find your account details, in the ‘Contactless Mobile settings’ section of the Barclaycard app.
To set up a TfL online account for your contactless Barclays debit card or Barclaycard, just go to tfl.gov.uk/contactless.
