Very interesting but couldn't get it to work with my smartphone. Even with a 250Ko image file, I got bored before it finished ! My camera may be too low quality and/or my monitor too small.

A barcode size parameter may be useful (even though it reduces throughput) so that it is easier to scan on all devices.

Multiple sizes isn't a bad idea. I'm not sure I know enough about what sizes would be appropriate though. :)

Transfers getting stuck like that usually is an indication that the decoder can't reliably find the 3+1 corner pattern. I might add a toggle to the decoder app that trades speed for more reliability.

That said, there are some failure modes that are harder to fix: I had a mysteriously slow transfer that was driving me nuts, until I noticed that my mouse cursor was on top of one of the corners.
