A government agreement between Transport for London (TfL) and the operator Govia Thameslink Railway (GTR) has introduced the pay-as-you-go Oyster and contactless cards services at Gatwick Airport, London.
The technology allows a hazardless and faster journey for rail passengers travelling between the airport and National Rail services in London.
London mayor Boris Johnson said: "Our Oyster and contactless ticketing system has transformed the way people travel around the capital.
"We've already extended our pioneering approach to a number of key routes outside of London and it's great news that it lands at Gatwick Airport today."
Transport Secretary visited the airport to be a part of the launch of the technology, which is now available for Southern, Gatwick Express and Thameslink services from London to Gatwick Airport, and on Great Western services between Gatwick Airport and Redhill.
Five other stations along the route, Earlswood, Horley, Salfords, Merstham and Redhill will see the use of pay as you go technology that will reduce long queues at the ticketing counters.
Transport Secretary Patrick McLoughlin said: "The introduction of Oyster and contactless gates at Gatwick Airport station mean even more passengers get the advantage of a quick, simple, easier journey when travelling between central London and one of its major gateways."
The pay-as-you-go technology is cost-effective, costing £14.00 at rush hour and £8.00 at normal traffic hours.
Gatwick Airport CEO Stewart Wingate said: "The launch of Oyster and contactless payments at London Gatwick is a game-changer for our passengers and will help to make journeys even easier and ticketing considerably faster.
"The introduction of a single ticketless system will create seamless connectivity to the Greater London transport network and this is only the beginning of the transformation of Gatwick's rail services."
Since the introduction of contactless cards on the TfL network in September 2014, there have been over 250 million contactless journeys made.
Over one million contactless journeys are made each day on London's transport system.
