I actually like the idea of cutting out the middle man and tying in a rewards program. It is not a new idea as it follows reward incentive programs that everyone from airlines to retail stores have had for years. While we can not be sure that the saved credit card fees will not be pocketed, if they are not, then CurrentC could become something great.

The premise itself I am a fan of. Using QR codes however, not so much. The infrastructure can be changed though, if QR codes become too cumbersome, they have the power to change it.

I was being partially sarcastic in my initial comment, but partially serious.
