I was browsing a blog on my phone about android apps and a guy had posted barcodes for apps and didn't include links. I know it's a dumb thing to do, but I would like to be able to scan them if it happens.
So, yeah, trying to read QR codes, but might as well include product barcodes as well.
I feel like it wouldn't be that hard to do... just put the phone's screen as input rather than the camera. It should be easier to scan also since (unless it's a photo of a barcode) it will be straight and perfectly focused.
