I have a QR generator for windows from portableapps. (Zint)
I have a question on your barcode scanner since I've tried several. Does this one also give you prices and comparison (local and online)? I use it for multiple purposes.
Zint is not a scanner... obviously, since it runs on Windows, it just generates codes. As to iOS or Android scanners, I use RedLaser/iOS... and I think that it does what you're lookin' for.
