Overview

  • The system’s 30th anniversary, marked Wednesday, featured a public exhibit in Rio that displayed the 1996 prototypes used in Brazil’s first electronic vote.
  • At his swearing-in the same day, TSE president Kassio Nunes Marques praised the device as a democratic asset and said Brazil’s vote reception and counting are the most advanced in the world.
  • Projeto Confia reported that more than 45% of recent false election content attacked the machines’ operation, often pushing bogus technical claims about the confirm key or auto-completing numbers.
  • Polling shows trust has slipped, with a Quaest survey in February 2026 finding 53% express confidence versus 82% in a 2022 Datafolha measure.
  • Today’s machines use encryption, digital signatures, biometrics introduced in 2008, and regular public security tests, and election authorities are preparing the system for nationwide voting on October 4.
