The dual, and multiple, system can be done without paper ballot.
There is nothing "magic" about paper as a record medium. I
can send a link for a paper on this that was presented at the
Tomales Bay conference on voting systems last year, using Shannon's
Tenth Theorem as the theoretical background, introducing the idea
of multiple "witnesses". If two witnesses are not 100% mutually
dependent, the probability that both witnesses may fail at the same
time is smaller than that of any single witness to fail.

Cheers,
