Yes...But maybe there's a way of using the NFC function of suitably equipped phones to "scan" the QR code on a smartcard reader?
You can add e-tickets to your phone wallet which will then allow you to present the Aztec code on your phone to the reader.
...you can buy a ticket and have it instantly delivered to your phone as an ITSO ticket, which you then just present via NFC. Simple.but your journey might be an hour quicker because you didn't miss the train because of a long at the ticket machine.
With the greatest respect, you are increasingly in the minority. Whilst I appreciate that ticketing needs to remain accessible for all, it cannot stand still for the minority who are not digitally enabled. It will, necessarily, become more inconvenient for those people who wish to still pay cash for a physical ticket at a ticket office.NO !!! nor a debit / credit card
