Also a good fallback if your phone screen cracked 2 hours before. But I can imagine part of the challenge they are facing here are scalpers. TicketMaster app 'rotates' the actual ticket every 30 seconds. Can't rotate paper.
I'd think that having a 2nd factor like presenting ID that matches the ticket would be sufficient there though.
