A specialized technician configures a Brazilian electronic voting machine, ensuring the integrity and security of the electoral process.

About this subject

The Brazilian electronic voting machine, developed by the Superior Electoral Court (TSE) starting in 1996, revolutionized voting in the country. Since full implementation in 2000, the system eliminated common paper ballot fraud and reduced vote counting to hours. Each model, such as the UE2020, has its own operating system and robust encryption. The technician in the image performs pre-configuration, which includes installing voting software, functionality tests, and sealing the device. This process occurs in polling stations across Brazil, often in remote Amazon locations. The voting machine has no internet connection during voting, and data is transmitted via encrypted network only after polls close. Fun fact: Brazil is the only country to hold fully computerized elections nationwide, with over 400,000 machines used per election. Preventive maintenance is crucial to avoid failures, and technicians undergo intensive TSE training.
