Probably just a variation on how Jukeboxes are done now. I'd imagine Pins will be on-line & you'll download an app to your phone. You'll have a "pinball account" and be able to put credits on the pin, watch scores, do tourneys and stuff like that. There will be a $$ cut off the top of course, but that's the way it goes.
It's becoming pretty popular. I know with Jukes, you can play a crappy song in a bar you're not even at!
