I think the first machine doesn't have to be secure because you confirm 
your vote
at the second one, and if something is wrong you would go back to the 
first machine
to re-enter it.

It seems as if the idea is basically a front-end to David Chaums system
(or the similar Neff system)

Maintaining secrecy could be an issue with this. Presumably, there is
no attempt to hide your voting selections at the first machine (because you
could change them later), but it looks a bit dodgy to me. I'd like to read a
first-hand description of the system though.

Also, I wonder are the "frogs" re-usable. It would be pretty expensive 
to run
if not.
