I like it! Just chiming in to say that, to oppose all the nay-sayers you'll always get on HN. I think I heard a similar concept pitched on a Startup Weekend once. The problem then was to make it so easy to use (seems you're on the right path there), maybe even without having to scan the QR code (add a 'Get in touch with my owner right now: ottomon.net/3az4xy' under the QR code, or something).

And to repeat what the other commenter said, why wouldn't you just print your phone number or email on there? Privacy is the biggest (only?) reason, I guess. Maybe you should focus more on that on your landing page. You want people to contact you if you parked someone in, but you don't want them to know your name and show up at your house at weird times just because they wanted to be friends with 'that guy with the expensive car'. People are weird.

How will you make it profitable, though? Only obvious thing I'd pay for is to get a nice pack of customized stickers/iron-on-patches/etc in various sizes.

Thank you for the encouraging feedback. Yes, privacy is one of the reasons. And you got it, the high quality stickers and pre printed accessories is what i intend to sell.
