Wow - gamification meets QR Codes! Here is a game involving the simple exercise of scanning QR codes. I'm not playing yet but didn't want that to keep me from sharing what looks like a pretty neat exercise. The teams look primarily Canadian (Ontario) but there are some New Yorkers. Get your team going early - looks like a lot of fun.
Drop me a note here if you get involved in playing, would enjoy knowing what you think. Oh yeah, this one pays money as prizes!
Qriket is the real-world mobile game that lets you and your friends win real money just by scanning QR codes!
