The idea is to use a Telefax machine for endpoint security, with

Would it not be simpler to use a modem?
Good question. My thought was that Telefax is still used, among
lawyers, doctors, business folks etc., and brand-new Fax machines
can be bought on Amazon etc.
I thought about that too, but in case the document would be several
pages long and would not fit into a QR-code. Ok, one can split the
large document and insert then several QR-codes into one Fax page.
The largest standard QR code can hold just under 3kB of data in a
single
image. If you need more than that you would probably have to split
across multiple sheets no matter what encoding system you choose.
Yes, do you know of any QR-code software (open source) which could
do that task automatically, i.e. split a large (encoded) message into
several QR-codes and reassemble later?
