Paper works, and it works well. Anyone that can count can validate a single precinct Add to that there's not really a need to speed up deployment of the results for elections and referendums in Switzerland. Except for the "house of representatives" (Nationalrat) where it can take a tad longer due to the complexities of the vote, results are usually in at voting day before 6pm (Voting closes at noon). I'm also deeply reluctant to accept the necessities of electronic voting. Given all parameters it's a really hard (if not impossible) problem to crack.
