QR Codes for Files on Google Code

Solution 1:

The QR code contains the file URL not the file SHA1 Checksum. If you check the html for the image you will see the title text says "File download URL". It is common to see these codes in situations where you may need to download the file to a mobile device or access the webpage from a mobile phone..

Programs like QuickMark can be used to scan the QR Code from your phone, and if a site doesn't provide a QR Code you can use something like this Google Chrome QR Code extension to automatically generate one. I use both of these and use them once or twice a month.

You basically then just use the camera on the phone to take a picture of the webpage while it is displayed on your desktop computer and open the URL in the mobile browser, sort of like Copy & Paste between two computers.
