Why is there a requirement for optical scanners? In other democratic countries, the counting of ballots is still a manual process (e.g. UK https://theconversation.com/explainer-how-britain-counts-its-votes-41265 https://theconversation.com/explainer-how-britain-counts-its... or Germany https://www.dw.com/en/german-election-volunteers-organize-the-voting-and-count-the-ballots/a-40562388 https://www.dw.com/en/german-election-volunteers-organize-th... ), which, while labour intensive, seems to work.
