I saw a poster advertising this at Guildford today. I can't see any previous mention of it here despite it apparently starting in September.
South Western Railway, in partnership with Great Western Railway, are trialing an exciting new smart ticket which will allow you to carry your season ticket on your Android™ mobile phone (sorry Apple™ users but this isn’t available for you just yet!). This will give you greater convenience, allow you to buy your ticket when you want (within 14 days of travel), with no need to queue or wait for collection.
To be part of the trial you must have a compatible Android™ phone (running 4.4 Kitkat operating system or higher with NFC and HCE functionality), a Gmail™ account and commute (starting and completing your journey) between Salisbury and Portsmouth including stations via Eastleigh and Fareham, or Woking to Portsmouth using any station along the route, and submit at least one survey. The trial will start this September, so why not get involved to help shape the future of rail ticketing.
We really want you to be involved so you will receive a £10** travel voucher for taking part. You will also be automatically entered into a draw for the chance to win an annual season ticket (worth up to £4,612*). You’ve got a great chance of winning as our trial will be limited to only 200 participants and selected trialists will receive a Samsung Galaxy S8 to use for the trail and to keep afterwards!
