Customers can now use Samsung Pay on their mobile phone to pay for using London transport.
The new payment app, which can be downloaded from the Samsung Galaxy Apps store, supports MasterCard and Visa credit and debit cards from major UK financial institutions.
It can be used for pay as you go journeys by bus, Tube, tram, DLR, London Overground, TfL Rail, Emirates Air Line, River Bus and most National Rail services in London.
Samsung has worked with TfL to allow users to set a payment card specifically as a transport card to use on all TfL services and most National Rail services in London.
Customers add their payment card to the app and nominate it as a transport card.
Once registered, the phone screen does not have to be on - users touch the middle of their phone on the yellow card reader in the same way they use their Oyster or contactless payment card to pay as you go.
Shashi Verma, chief technology officer at TfL said: “It's great to see another mobile ticketing option introduced into the market.
“More than 900 million contactless journeys have already been made in London and the ability to nominate a specific transport card with Samsung Pay will significantly benefit customers using this simple and secure mobile payment solution.”
