It's a somewhat solved problem already
Glastonbury festival has made you register your name, address and a mugshot for about a decade or so now
It gets printed on the ticket.
If you don't look like the person on the ticket and don't have the ID of the person named, you're not getting in
Kinda invasive, but it's basically killed touting
Not quite sure how you do this with hardware, perhaps tying it to the device?
Maybe you need to own the device for a year or two before you're allowed to use it with another account
