This is not true at all, it’s much easier to falsify paper votes than it is to falsify any good electronic voting system. This is a fake news perpetuated by people who are finding difficult to falsify electronic voting systems and want to, for example in Brazil the last election held with paper ballots was in 1994, and it has been demonstrated that those results were frauds, one of the elected candidates in that election has been one of the most vocal opposers to electronic voting.
