Customers of online ticket provider Thetrainline.com will be able to buy and receive tickets using their mobile devices later this year.
The Masabi-supplied m-ticketing system will allow customers to buy and display tickets for any route across the National Rail network.
Thetrainline hopes to reduce queues at stations during peak times. According to the operator, the application can also be used on almost any device and is user-friendly enough even for those who have never bought tickets using a mobile phone.
As well as purchasing tickets, clients will be able to either display the ticket - which includes a secure barcode - on the phone's screen or collect a paper ticket at the train station.
"Mobile ticketing has focused on niche trials to date, but we needed a partner able to address the specific issues of a mass-market rollout in the National Rail network." said Richard Rowson, product development director of Thetrainline.com.
Rowson said the m-ticketing platform was chosen because of capabilities including security, usability, barcode standards and mass-market phone compatibility, as well as the supplier's understanding of UK rail.
It follows ongoing implementations of barcode scanners by UK rail operators on board and at stations.
Heathrow Express has been an early adopter of the technology.
