Waiting in long lines at the ticket machine could a thing of the past on Southern Rail, thanks to millions of pounds worth of investment into mobile ticketing.
It means anyone wanting to board a train at a large number of stations on the Southern network can do so without having to queue at a machine or ticket office.
The technology is pretty straight forward.
People purchase their ticket on the Southern Rail app, which then produces a QR code that is scanned at the ticket barriers.Southern Managing Director Angie Doll said: "Customers can already travel safe in the knowledge that our trains and stations are kept clean with a long-lasting viruscide on all touch points.
"Now e-tickets and our Key smartcard make it even quicker and easier to book a ticket online, speeding up the journey through the station, minimising contact and helping everyone to socially distance."
The rail operator insists the technology 'compliments' the work of its staff and that people will still see a visible presence on its network.

Across the Southern, Thameslink and Great Northern network a further 29 stations will be added by next Spring. These include:
Rail Minister Chris Heaton-Harris said: "Making public transport more modern and accessible is a top priority in all the work that we do.
"The roll-out of smartphone ticketing across the Southern network makes it quicker and faster for passengers to pass through stations, simplifying their journeys and delivering a more seamless experience."
