Some years ago, in Germany a computer magazine patented "The Paper Disk",
a method to publish large (for that time) amounts of code in a machine
readable form. Exactly how you describe it: rectangles filled with black
and white cells, with some ecc bits at the edge. Fitted to the dimensions
and resolution of (for that time) wide-spread hand scanners.
Yes, it worked. Don't remember the exact numbers of time required to
scan one megabyte - and to reconstruct it from the black/white pattern.
But it was easier to use than OCR (who did OCR on an 286 anyway ?).

Just my 0.02 Euro...
