From another thread:
It wasn’t just the Southport possible complication, I’m afraid I’m one of those dinosaurs who still prefer CCST tickets regardless...
CCST tickets are being discontinued; paper tickets are increasingly being issued on paper roll (similar to "till roll" paper) stock with barcodes. The new style paper tickets are of poor quality and fade easily.
The choice is increasingly going to be between having your own PDF Aztec ticket - which you can optionally back up to another device and/or print your own copy - or a till roll style Aztec ticket.
Either way, magstripe technology is costly to maintain and is rightly being phased out.
Not least because of the risk of dropping my phone while fumbling about with luggage at the barriers.
In that case, when travelling alone, you may want to print a copy of the ticket. When travelling in a group, all members of the group can have their own copy of all tickets, which could be presented by the person with the least luggage.
Spotted a new poster today in the platform 3 waiting room at Lancaster, depicting someone showing a phone with zero battery and saying “my phone just died“, overwritten with a large warning “£100 fine, you MUST have a valid ticket”.
Exactly the same argument could be made about losing a paper ticket. People can and do lose paper tickets, have wallets stolen, etc.
Except, with a paper ticket, there is no backup. E-tickets can be backed up easily.
Hardly gives you a warm glow about e-tickets.
It's more a case of companies such as Northern not wanting to give a warm glow about train travel; they see passengers as there to be exploited for the maximum amount possible, and as potential criminals. This behaviour is encouraged by the DfT.
