QR-Code tracking website subdomain

You know all the hype about QR-codes, right? A sort of barcode, which – if you scan it with your mobile – directly leads you to a electronic business card, coupon, website, e-mai or whatever. It works very simple: you enter the information into a QR-code generator (loads of them free on the web), and you get the QR-code. Or you put the info on a web-URL and create short-URL in Google, and you get the QR-code. Now, as people like to now how interested people are, loads of company have set-up a QR-code tracking service. Charging money of course. I want to do this for free, as a a service to whatever customer and as a creator of traffic to our website. It is not difficult, as Google URL-shortener ([login to view URL] ) does the whole process for you. These companies just put a thin management layer with an own look and feel on top of it. I want to do the same. I created a simple PPT.
