Some things SHOULD NOT be digitalized, no matter how advanced tech is in other sectors. There is a reason why many, if not most US police departments, county/municipal/state record services, and courts still use typewritten file storage, hire typewriter clerks, and keep paper archives stored in traditional metal filing cabinets with some documents converted to microfilm. There are thousands of employees of these agencies right now whose daily work involves just paper, ink, and spring clips, rarely ever needing a computer or smartphone during their shifts. These records are unhackable and cannot be altered or corrupted, except by physical breaching and burglary, the chances of which are almost nonexistent.
Same should be done with voting. There are plenty of funds already available to hire the human power needed to physically sort and count punched paper, if these funds are not being constantly diverted into the pockets of greedy officials.
