That's the same thing unless you have some kind of double authentication to prove the person who bought the ticket is the same one using it at the show. Like, say, matching it to an outside-authenticating number, like SSN or driver's license number.

Otherwise a scalper can just use "employees" to purchase a few tickets (the limit) at each venue, and resell them.

The fans would know about the discount, so I'm sure they'd be more than happy to give their name and show a driver's license at the door.

Let's also have some backscatter imagers to make sure nobody brings weapons into the venue. Emulating the airlines is a business model guaranteed to succeed!

It's an optional method for fans to get discounts. I think this comparison is too far.

I really hope you're joking or trolling here, though I doubt it... Clearly this would be optional, I don't think it's a valid comparison in the least.

I suspect it would be illegal to use SSN, but it's still an interesting idea.
