I'm finding the implementation of mobile/e tickets a bit of a pain in many cases, for example
- some apps such as Greater Anglia require each out and return to be downloaded and activated separately (also annoying for day return tickets for a single adult)
- Very slow to go in and out for each ticket
- No link to the railcard app to show a digital railcard
- Painfully slow at barriers as have to go in several times, and often can't just use the same barcode multiple times, or swipe side to side to allow multiple people through the barriers.
- IsThe German DB have a single barcode that covers all passengers and reservations
- The DB app has a button to show the BahnCard - granted this would have to open another app in the UK, but no reason why it can't be done, and also select the right railcard.
- The Dutch NS app it's easy to swipe side to side to scan other people in the group through the barriers.
