In countries like Canada and Russia, you have to vote in your neighbourhood on a paper ballot. Your ID is checked and your name crossed off the voter list by poll clerks from your neighbourhood. Those same poll clerks count the ballots on site. They never leave the building. Representatives of the candidates watch the polls all day and watch the ballot counting.

There is an electoral reform movement in Canada that believes this is not democratic.

They want the system changed to proportional representation or to ballots where you number the candidates in order of preference.

Both these ideas would require mechanical ballot counting/rigging.
