Technician configures the Brazilian electronic voting machine, a model used since 1996, ensuring security and swift vote counting.

About this subject

The Brazilian electronic voting machine, known as urna eletrônica, is a voting device developed by the Superior Electoral Court (TSE) and first implemented in the 1996 municipal elections. Since then, the system has evolved to incorporate encryption, digital signatures, and biometric identification, making the Brazilian electoral process one of the fastest and most secure in the world. In 2022, over 156 million voters used about 577,000 machines nationwide, with results tallied within hours after polls closed.

The equipment is designed to operate autonomously without internet connection, preventing external cyberattacks. Each machine runs a customized Linux operating system and voting software that is audited by political parties, oversight bodies, and specialists before elections. The technician in the image performs pre-configuration, including software installation, functionality tests, and insertion of media containing candidate and voter data.

Beyond security, the electronic machine drastically reduced counting time. Before the electronic system, manual counting of paper ballots took days; today, results are released the same night. The technology also significantly reduced fraud, such as multiple voting or result tampering. The current model, the 2022 machine, features a touchscreen display and numeric keypad, and prints a visual verification receipt without storing the paper vote.

Interestingly, Brazil exports its voting technology to other countries like Paraguay and Argentina, serving as a reference for developing electoral systems. The system's reliability is publicly tested through public security tests, where hackers are invited to try to breach the system, reinforcing transparency.
