You could make the tickets refundable if you don't want to piss off people not being able to go last second. I'd also say making scalping into a felony (by requiring forged ID's) is a very good place compared to where we started.

Be it phones, old enough accounts (steam for example), emails which have been subscribed long enough. Hell, plant an underskin chip if you're doing a distopian cyberpunk convention.
