A voting machine is a machine used to record votes in an election without paper. The first voting machines were mechanical but it is increasingly more common to use electronic voting machines. Traditionally, a voting machine has been defined by its mechanism, and whether the system tallies votes at each voting location, or centrally. Voting machines should not be confused with tabulating machines, which count votes done by paper ballot.
Voting machines differ in usability, security, cost, speed, accuracy, and ability of the public to oversee elections. Machines may be more or less accessible to voters with different disabilities.
Tallies are simplest in parliamentary systems where just one choice is on the ballot, and these are often tallied manually. In other political systems where many choices are on the same ballot, tallies are often done by machines to give faster results.
In ancient Athens (5th and 4th centuries BCE) voting was done by different colored pebbles deposited in urns, and later by bronze markers created by the state and officially stamped. This procedure served for elected positions, jury procedures, and ostracisms. The first use of paper ballots was in Rome in 139 BCE, and their first use in the United States was in 1629 to select a pastor for the Salem Church.
The first major proposal for the use of voting machines came from the Chartists in the United Kingdom in 1838. Among the radical reforms called for in The People's Charter were universal suffrage and voting by secret ballot. This required major changes in the conduct of elections, and as responsible reformers, the Chartists not only demanded reforms but described how to accomplish them, publishing Schedule A, a description of how to run a polling place, and Schedule B, a description of a voting machine to be used in such a polling place.
The Chartist voting machine, attributed to Benjamin Jolly of 19 York Street in Bath, allowed each voter to cast one vote in a single race. This matched the requirements of a British parliamentary election.
