Oyster cards might one day be a thing of the past, as Londoners have been busy using their contactless bank cards to pay for commutes.
Transport operator TfL announced that one in seven contactless payments in the UK now take place on London transport, as it celebrates one year since introducing the payment service on its network.
More than 180 million journeys have been made using contactless payments on London's transport network since its launch in September 2014.
The technology was developed by TfL to remove the need for customers to top-up, and fares are capped - with the best value fares calculated automatically.
Contactless payments can be used on London Underground, tram, DLR, London Overground, buses, TfL Rail, the Emirates Air Line and most National Rail services in London. Payments using the technology now account for a fifth of all pay as you go journeys.
Mayor of London Boris Johnson said: "It's been an astonishing 12 months with so many Londoners embracing contactless technology on our transport network.
"It is clear passengers love using the payments to travel, and why on earth not - it's quick, it's easy and ensures you get the best fare. It's yet another example of how we continue to invest in the latest technology to make getting around the Capital as easy as possible."
One in seven of all contactless transactions in the UK now take place on London transport, with more than 900,000 journeys made using contactless cards on Friday, September 11.
Canary Wharf Tube station is also one of the top five TfL stations for the number of contactless journeys made.
TfL's director of customer experience, Shashi Verma, said: "The first year of contactless payments on TfL services has been a huge success. Introducing the technology is just one of the many ways we are making paying for transport easier for everyone travelling in London.
"More than 20% of our pay as you go customers use contactless payment already because it is so quick and easy. There's no need to top-up, you just touch in and out with your credit or debit card."
