Good for you, now explain how millions upon millions of votes can get reliably tabulated for state and national offices.
Also, take a look at 2004’s WA State Gubernatorial election where bags of ballots and absentee ballots unsealed by felons on parole were used to steal the election from a great GOP candidate, and where the Director of Elections was forced to resign and move out of state. All paper fraud, so paper and ink ain’t the complete answer.
American ingenuity can get at the root of the problem. But it has to be funded and diliently pursued.
Our nation and constitution is designed for a moral and ethical people. To stop corruption we must each be willing to serve on election commissions, be election holders or poll workers. We must be observers on behalf of the candidates we support.
Votes are tallied per precinct, more precincts = fewer votes to tally, quicker results. This is problematic for high density areas of the country, but the solution is still the same, more precincts with tighter control of the polls and voter ID.
However, if the goal is to control the vote then by all means use software driven corruptible equipment with larger precincts, centralized control and accounting, with no voter ID accountability.
