Contests are created by campus managers via the administrative Web application. Contests are pushed out to the iPhone and Android apps we created which are in use by college students nationwide. Students get clues about coupons and other fun things hidden around campus, from there the game's afoot. When a student finds a prize, she must activate the prize by scanning the prize's QR code with the app. At that point all other users on that specific campus are notified that the prize has been found.
