New contactless payment systems are to be introduced on the London Underground in the next few weeks.
A trial of 5,000 underground users will be the first to test the contactless system, which allows the user to pay instantly using their debit card.
The scheme will be extended to the rest of the public next year.
The Evening Standard reported that this may lead to the end of the Oyster card on the Underground, as the funds are easily debited from their account within seconds.
Contactless payment already exists in many high street shops and fast food outlets such as McDonalds, Pret a Manger and Subway.
The system is already in place on many London buses. Instead of topping up an Oyster card for a bus journey, passengers are able to use their debit card in this way to pay for their journeys.
