Does anybody out there use a QR reader app? I think this is pretty cool and to know if it is worth purchasing an app for it.
I use Mobio, which is free and runs frequent contests and functions as a QR code scanner as well. I mostly only use it for the QR and the contests but it can do other things, too.
War.Eagle - QR codes are those funky black and white squares you see in stores and such - they function like UPC codes on food boxes, sort of - most of the time they direct your phone browser to a website for a store or manufacturer or contest entry, etc. No typing or url's, just scan and go.
