First off what are they?! (see the footer for mine)
here’s the QR Code for this page:
What that does is (if your mobile phone supports it) will send you to this page, on your mobile device, just by taking a photo of it on your camera, or using a dedicated program like QuickMark which is what I use on my HTC Touch Pro. (They have a free and you can purchase it for more featues, but I find the free version does what I need it to, as well as generate a QR Code for your contact list if you need to share a number this makes it worlds easier!)
So I’ve also added one at the footer, so if your browsing a page, that you want to view in your mobile device just snap a picture and your off and running! I’ll also start doing them for item’s that I will be making available for download.
It’s taken off in china, you can find stickers, codes on billboards (I did see one in San Francisco but it was too small to get while driving.) I even have a sweatshirt that I made for my old mobile site so get on the QR Code bandwagon and ride!
