I also like this project a lot, I see a great future here.
I think the possibilities is endless if you really think about it.
I see this is both for advertising/event based applications, for games and for health apps.
Any other ideas?
I had a weird thought that it might be used to restrain the pace of delivery vehicles to the legal speed limit. So Donatos or whoever would automatically place GEO's along the path the delivery person was taking, but they would only be valid if the delivery person was there at a certain time or later, and not after the delivery. So if they drive too fast, they don't get the coin. Kinda strange but I think it might actually work.
No.
They already have such mechanisms. Satellite linked devices monitor the movement of vehicles, and they govern (or limit) the top speed of vehicles.
