Electronic voting machine

A voting machine is a machine used to register and tabulate votes. 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 the mechanism the system uses to cast votes and further categorized by the location where the system tabulates the votes.

Voting machines have different levels of usability, security, efficiency and accuracy. Certain systems may be more or less accessible to all voters, or not accessible to those voters with certain types of disabilities. They can also have an effect on the public's ability to oversee elections.

The first major proposal for the use of voting machines came from the Chartists 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. Each voter was to cast his vote by dropping a brass ball into the appropriate hole in the top of the machine by the candidate's name. Each voter could only vote once because each voter was given just one brass ball. The ball advanced a clockwork counter for the corresponding candidate as it passed through the machine, and then fell out the front where it could be given to the next voter.

In 1875, Henry Spratt of Kent received a U.S. patent for a voting machine that presented the ballot as an array of push buttons, one per candidate. Spratt's machine was designed for a typical British election with a single plurality race on the ballot. In 1881, Anthony Beranek of Chicago patented the first voting machine appropriate for use in a general election in the United States. Beranek's machine presented an array of push buttons to the voter, with one row per office on the ballot, and one column per party. Interlocks behind each row prevented voting for more than one candidate per race, and an interlock with the door of the voting booth reset the machine for the next voter as each voter left the booth.
