QR Codes for Files on Google Code

When I open a google code download page, there is a QR code at the bottom.
What kind of devices will read this human unreadable QR code?
I cannot figure out why google put a QR code there.
If such a device is so powerful to recognize this image,
why it's cannot just read the ascii text in the page?
I really don't know the purpose.
