Ever wondered what this is? It's called a QR Code or Quick Response Code.

QR Code for All About Mobile Life

You see these codes on a lot of Kaywa blogs. By using a QR Code Reader on your mobile phone you can scan these QR Codes and bookmark the address of the mobile version of this blog.
Then when you are no longer in "working" but in "idle" mode, you can reopen your Kaywa Reader, go to your history and connect to the internet. The content you'll see is strictly the same as on the PC/Mac web, but it will look much better and load much faster on mobile devices.
