Revision3 posted an interesting video recently. It's called:
Barcode Scanner for Android App Downloads - AppJudgment
and it's all about getting barcode scanners for your phone. Now, you gotta have the right phone to do this, but the advantages are awesome. Let's say you're out shopping and want to find a little more information about a product, just scan the barcode,or QR code, use the application and you can find information all over the web. Compare prices, research details and more. Who would have thought that barcode scanning could be so much fun.
