To be more precise, there are 3 things that must be met for a vote to be considered acceptable, digital or not: * it must be anonymous, ie nobody but you should know you you voted for * it must keep integrity, ie nobody can change your vote * it must be verifiable by all participants Paper vote makes it easy to meet all criterions: just keep an eye on the ballot and you will be relatively sure that everything is fine. On the other hand it is impossible to have all those conditions with a digital vote, if only because digital anything isn't easily verifiable by all participants.
