Cannot agree more. I say things all the time here that people hate and downvote me for but the numbers are even more useless here than on Reddit so it’s difficult to care.

Step 1: Go to station ticket office

Step 2: Tell ticket agent where you want to go

Step 3: Give cash to ticket agent

I can’t comment on the practices of Italian transit agencies, but in the US, when you buy a train or bus ticket, the email just contains a QR code which you give to the train conductor or bus driver to scan. It also typically includes your name as well (tickets are not transferrable to prevent resale) but I don’t see a reason that you couldn’t design a system with simple bearer tickets.

So this system could just take your payment (which is not anonymous anyway since a name is required to process card payments) and then show you a QR code and tell you to take a screenshot of it.
