At this point couldn't we have all tickets be printed with a QR code that is used to look up if it's a valid ticket or not (if you have the QR code you have the ticket)? I don't get why forgary would be a thing if the ticket ID's were GUIDs or something else that you can't brute force while physically in line at the event.

The real reason, I fear, that we need the apps is data harvesting to be sold to data brokers.

Forgery here would be stealing someone else's ticket code for resale, or selling the same ticket multiple times.
