I recently got a HTC Tattoo and had problems scanning QR and bar codes on my monitor. If you have a Tattoo then you probably know how crappy the camera is. It has no autofocus which makes close-ups really blurry and small codes near impossible to scan.

Try it out with these examples:

small QR code

large QR code

I cannot scan the small one on my 21″ 1920×1080 screen, the bigger one scans great. Luckily they resize very well.

I’m using Firefox with the Image Zoom extension installed. When you come across a QR code that won’t scan, right-click it and hold the button, then zoom in using mouse wheel. Scan again, and bingo.
