I think a computer shouldn't be used, is better like in TD state where there is a paper trail, like Canada, that allow to recount easily if it is necessary.
Someone was floating the idea that in the future people could vote using their phone. It's a terrible idea, like a computer anything digital could be hacked.
By the way, if you are able to vote and don't do that, you should pay a fine like $ 50. Democracy die in people's apathy.
