Technician configures a Brazilian electronic voting machine, a model used in elections since 1996, ensuring security and fast tallying.

About this subject

The Brazilian electronic voting machine, known as 'urna eletrônica', was developed by the Superior Electoral Court (TSE) to replace paper ballots. Implemented in 1996, it has been used in over 15 national elections, with more than 140 million registered voters. The technician in the image performs pre-configuration, including official software installation, integrity tests, and seal verification. The process is audited by political parties and oversight bodies. Each machine has digital certification and records votes encrypted, without internet connection, preventing remote attacks. Tallying is done locally, and results are transmitted via encrypted network to the TSE. Since 2020, biometric identification has been added to reduce fraud. The system's reliability is internationally recognized, adopted by countries like Paraguay and Argentina.
