That's pretty cool.

Interestingly, most people using an Android phone can do that without the use of a computer or scanner.

The only caveat being that you may need the same QR app to decode it. I generated mine using QR Droid Private. Two other apps weren't ale to decode from the image so I'm assuming they'd also choke when scanning. QR Droid was able to decode it.

Man, that's got to be the largest QR code I've ever seen!

Cool, I'm going to give that a try! We tried the ZXing scanner initially. It was able to scan it, but had trouble interpreting the contents -it kept trying to map it to a non-existent UPC code.

It probably has something to do with the amount of data. The file I did when I checked was 11k. I think it's a pretty cool trick, too.
