QR codes are like barcodes, but they use two axes to get information.
If you know how a barcode works, imagine that, but with an x axis and a y axis instead of just an x axis.

To read them, find an app or whatever that uses your camera to decipher and read the data in a QR code. Usually you have to take the QR code, and fit the edges of it with the markings on the screen for it to read properly.

Go to the Market and get "Barcode Scanner". That's all you need.

You can then use the codes to get info, links and downloads wherever relevant.

The QR you posted goes to MalcolmHall.com

Thanks guys. Well i have the barcode scanner , but it didnt read the information.
Ok ill try again.
