Your link doesn't suggest that paper voting doesn't work, it suggests that india is a corrupt nation that couldn't manage to enforce its monopoly on violence during that time. You could in principle also just beat up everyone in the vicinity of the booth, steal their digital voting access and vote for them. You can't hack a container filled with pieces of paper.
