OK thanks. That would rule out a digital one for me - single point of failure, where said failure could result in hassle, penalties or even prosecution.
In fact it's odd - most retailers have ditched M-tickets in favour of E-tickets - it's virtually an industry standard now - and the collective consensus of this forum was that M-tickets were a bad idea and the move to E-tickets was the sound choice.
Considering a railcard has to last a whole year (rather than most tickets being just a single day), it makes no sense to me to go back to the worse solution for something that has to last longer and is used so many more times.
I'd always get a physical railcard where possible. Can't trust all this technological stuff to work when you need it.
Yes that's my thinking in this case. I'll use tech if there is a backup method, or if it is a short-term solution (eg instant cheap advance single to travel now....), combined with there being no serious consequences of failure... ie criminal offence.
I can't see how we can be assured that the apps, or Android/iOS, won't be fiddled with multiple times over a year and break at some point. It already happened to me with the Northern App when I had an month M-ticket on it - app updated one day, ticket disappeared.
