A fairly clever use of QR codes backed by financial results.
QR codes are ugly, and IMO very limited, but they have a lot of potential to change the way we interact with data. I have a QR code on my business card and love it when people just scan it and hand it back. Unfortunately, the format is too limited to put complete vCard details in a QR, but it’s a lot better than typing.
Some people think QR codes won’t make it because they aren’t regulated. Most bar code technologies are regulated or controlled. You can’t just make your own CPC code. But I think it is exactly this reason why QR is taking off. Anybody can make a QR code and load whatever they want on it. Now there are services popping up that use them just a DB identifier – and then provide lots of data.
