Journeys between London, Kent and parts of East Sussex will be made easier thanks to a £5.5 million plan to roll out smart cards across Southeastern’s network.

Southeastern will bring in smart cards, initially for season tickets only, as an alternative to paper tickets from December 2016. This follows a deal with the Department for Transport (DfT) as part of the government-funded South East Flexible Ticketing (SEFT) programme.

Work will now begin to upgrade Southeastern’s ticketing systems and equipment to allow passengers to use smart cards to travel across the majority of Southeastern’s network.

The DfT says smart cards provide significant benefits, including the ability to purchase online and avoid ticket office queues, and quicker entry through automatic ticket barriers.

Rail minister Claire Perry said: “Smart ticketing is a common sense innovation that makes life easier for passengers.

“It allows for more straight forward journeys and I’m delighted Southeastern will be rolling them out across much of their network.”

Southeastern is the latest operator to sign up to the government’s £80 million SEFT programme, delivered in partnership with the rail industry and transport operators.

SEFT aims to promote seamless and convenient travel on different types of transport across London and the south east by encouraging operators to introduce new ticketing technologies.

Because SEFT is government-backed, smart cards will operate seamlessly between different train companies across the region.

It also offers the future potential for more flexible ticketing products that could not work on paper-based tickets.

When SEFT is complete, 250,000 season ticket holders across the south east will be able to swap paper tickets for smart tickets, accounting for 202 million journeys per year.

Other train operators which have previously signed similar commitments include c2c, South West Trains, Govia Thameslink Railway and Abellio Greater Anglia.

Smart ticketing in the north has also received backing from the government, with £30 million announced in the summer budget 2015 to Transport for the North (TfN), part of which will go towards the rollout of Oyster-style smart ticketing.
