One ID for the entire order would be fine. You can buy 4 tickets, and go into the concert with your 3 friends. It often works this way even with no ID involved, I buy two tickets, add them both to my wallet, scan them both when my GF and I go to the show.
You COULD still scalp tickets if the person who bought them from you is going to walk in with you. But the scalper would have to eat the cost of one ticket to do it, and it's probably onerous enough to severly reduce the impact of scalping.
Every ticket must have one name and surname on it, no matter how many passengers it covers. That person must be traveling on the ticket.
You're usually asked for some kind of photo anyway because of discounts, which a very significant percentage of train riders are entitled to.
I think this is because tickets must be both printable and verifiable offline in case the train gets into a spot with no connectivity when the inspector is inspecting tickets.
Here, train tickets need to list every passenger along with their age and gender. This also enables you to cancel for just one person on the ticket without affecting the rest.
The ticketing system basically assumes no network connectivity. Ticket inspectors usually only ask you for your name and match it to their records. And only ask for and id in rare situations (you absolutely need to have yout id with you irrespective of infrequently you actually need to show it).
What if you need to arrive separately? Especially for a big event with tens of thousands of people, can be easier to meet up inside the venue on everyone’s timeline.
Then you should have thought of that when you bought the tickets I guess. Any change to the system to fight scalping is going to inconvenience regular users too.
As a frequent concert goer, I’d happily have to arrive with my group if it meant no Ticketmaster.
So that makes it a shitty system that is really solving nothing. If I hypothetically have a group of 14-15 year olds that I buy Taylor Swift tickets for, does that mean I have to accompany them up through the line? Just dumb.
There are really two options. Tickets are non-transferable, which means you need the name of the person and to check ID, and there's no scalping, like airlines. Or tickets are transferable, and you don't need names or IDS or whatever else but scalping occurs.
If you think scalping isn't enough of a problem to balance out the inconvenience of having to plan the ticket purchases better, well, uh, that's just like, your opinion, man. We'll agree to disagree. But it does mitigate a problem, scalpers inflating prices.
