The actual voting takes place on paper, and while it takes time to prepare the ballots and count the votes, the process of voting doesn’t take very longer than a few minutes for the individual citizen. From they enter the voting place till they are done.
I think that’s the way to digitize elections, you make them speedy for the citizens, but safe for democracy.
I can’t for the life of me understand why you would ever do a digital vote. It’s just so risky. I guess you save money by adding effectiveness to the process surrounding an election, preparing ballots and counting votes, but those parts of the process are owned by the public sector and I don’t think the government should ever value the safety of our democracy as less important than money. We count votes by enlisting employees of the municipality, members of political parties and paid help from local NGOs, and everything is monitored and counted a few times. It’s a little taxing, but everyone involved enjoy the process, and financially it’s not that expensive compared to paying a license for voting machines.
