Wow. I guess I hadn't realized that cameraphones elsewhere were
that far behind relative to the ones in use here and in Korea.

And the technology involved seems quite a bit different as well.
For example, the redundancy that's built into QR codes such that
even if part of the QR-code block is missing (up to 30% or
something as far as I recall), the code can still be read.
