About this subject

The Brazilian electronic voting machine, officially called urna eletrônica, is a digital voting device developed and used by the Superior Electoral Court (TSE) since the 1996 municipal elections. The system was created to replace paper ballots, eliminating fraud and speeding up vote counting. Brazil was one of the first countries in the world to adopt fully electronic voting nationwide. Today, over 150 million Brazilian voters use the machines every two years. The equipment is an embedded computer with no internet connection, designed to be secure and auditable. Morning configuration includes integrity checks, loading candidate lists, and printing the zerésima, a document proving no votes have been registered before voting starts. The electronic voting machine technician is a professional trained by the TSE or outsourced companies, responsible for ensuring each machine works correctly on election day. This role is crucial for the reliability of the Brazilian democratic process. The machine has an internal battery lasting up to 12 hours, an LCD display, and a numeric keypad for entering candidate numbers. Since 2020, machines also emit an auditable printed vote receipt, increasing system transparency.
