Electronic Voting Machine

The electronic voting machine is a special microcomputer purpose for elections, with the following features:

Tough, with small dimensions, lightweight, with energy independence and security features.

Two terminals constitute the electronic voting machine: the terminal of the poll worker, where the voter is identified and authorized to vote and, in some models of voting machine, where your identity is verified through biometric, and the voter’s terminal, which is recorded numerically the vote.

The poll worker’s terminal has a numeric keypad, where is typed the number of voter registration, and a liquid crystal display, which appears the name of the voter, if it belongs to that electoral sections and if he is able to vote. Before the license, in the sections where there is biometric identification, the voter has his identity validated by the voting machine. Thus, a voter cannot vote for another one.

The voting machine only records the indication that the voter has already voted. By internal shuffling and other security mechanisms, there is no possibility to verify  which candidate a voter voted, in respect to the Brazilian Federal Constitution, which determines the secrecy of vote.

Three small visual signals assist the pull worker, informing him that the terminal is available to the voter, if already completed his vote and if the voting machine is working connected to the electrical current or internal battery.
The voter’s terminal has the numeric keypad, which is registered the vote, and a liquid crystal display, which are recorded messages that guide the voter to register his vote.
