Connecting people: A strategic vision for rail — Department for Transport — “Our aim for 2018 is that, by the end of the year, both ITSO and barcode tickets will be accepted for travel on almost all of the network… We also expect much of the industry to offer smart cards that can be held in digital ‘wallets’ on mobile phones… We expect in the medium-term wider use of mobile phone-based ticketing, and in the longer-term to explore options that don’t require a physical check of tickets.”
