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.
Huge thanks as always to Mike Whitaker and his website 'Oyster Rail' full of invaluable information on payment and fares, go and have a look at: http://www.oysterrail.org.uk/
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) that's here on the TfL website: https://tfl.gov.uk/faresandpayments...
