QR codes - big business?

Quick Response Codes more commonly known as QR codes. They allow people with QR readers which anyone with a smartphone now holds, to be able to use their camera to access websites straight from their phone. I haven't really seen many QR adopters yet and with a growing number of smartphone users is it more likely business should start looking to QR codes.

Why not just type it in? its more fun to scan and see where it takes you :/

I can see a number of problems for some people who may not what to stop in the middle of the street to scan a QR code especially a busy one. However if we started to see them on adverts could it encourage customers to engage with your brand and perhaps take them to a site where they could review your business. Another function could be to get customers on your website whilst their out and I think that could be good for offering deals which once scanned they receive a coupon code to take to a local store. Customers could also find out more information about your company from an visual advert.
