The first electronic voting machine was used in the United States in 1964. It was called the “Electro-Mechanical Voting Machine,” and it was used in a general election in Philadelphia, Pennsylvania. The machine was invented by James F. Carlton and Frank Carver, and it used switches, relays, and gears to record and tabulate votes. This machine was a significant improvement over the earlier mechanical lever machines and punch card systems, as it reduced the likelihood of errors and allowed for quicker tabulation of votes. Since then, electronic voting machines have become increasingly common and sophisticated, with many different types and models in use around the world today.
