Printing Keys and using OCR.

If you want reasonably accurate data from OCR of scans of fonts not
specifically designed for OCR then you need to proofread the output
and correct as necessary.  Outside of tightly controlled
circumstances, OCR is not going to be fully reliable without this

I keep a paper copy of my revocation key in locked storage, and if I
ever have to use it I figure I'll just type it by hand.  It's really
not very many characters.  It would be more trouble (though more fun)
to try to scan and OCR it than to just go the low-tech route.

The barcode ideas sound interesting, but letterforms were designed for
a system that has very different ways of processing information, and
very different strengths and weaknesses.

Typically when a software vendor says that a product is "intuitive" he
means the exact opposite.
