When I saw the title I thought, that it will transfer a file entirely via continuous QR code scanning. But it would be probably too error prone and too slow, especially without a back channel to signify acks.

Maybe such a thing could work between two phones facing each other screens using front cameras. I wonder how fast could it practically get.
