It's publicised that if you use contactless to pay for travel in London, it's the same price as using an Oyster card. But that's not always the case. We went onto the tube, and made identical journeys using the two different methods of payment to prove what happens, and show you why it does.
Note: If you have a railcard discount (or similar) applied to your Oyster that will always be cheaper than contactless. Discounts cannot be applied to contactless payment cards.
For more details on capping, including how Contactless has automatic weekly capping (and Oyster doesn't) check out the TfL website.
