How could two-dimensional codes have been designed to be human-readable?
I was hoping to learn from the article how to manually read QR codes, but that format, at least, is much too complex to do with any efficiency.
At the end of the day, it's bits. Simplist case: 7-bit ASCII; eliminate masks (is that really so difficult for modern software to read sans the masks?); put error correction, length etc. in some corner where humans can ignore them ...
