What is the need for it? You want faster results? Not needed, elections don't need to be fast, they need to be trusted. You want to have less humans in the loop to be more efficient? Having humans in the loop is actually a feature not a bug as it distributes the trust on many actors. Paper ballots work just fine if done correctly and most democracies have a long history of knowing how to do them correctly with very high stakes. Electronic (or even online) votes are fine for low stakes stuff, like what the color of that new bridge ought to be, but not to select the fate of a whole nation.
