I was wondering if anyone knew of a linux app that could read qr codes using a webcam. I know about zbar, but it doesn't use a gui so there's no possibility to copy and paste the output.
What I'm wanting to do is run an offline ether wallet on a rasberry pi, and I need to swap information between it and my online computer without them actually being connected or using a usb stick. So I need to be able to transfer the to address via qr code to the rasberry pi. Hope that's about clear as mud. Long story short, I need my rasberry pi to be able to read qr codes, and have the ability to copy and paste them.
