Initiated in the early 1990s, the use of electronic ballot boxes was implemented in the entire country in 2000, at the most remote localities, as well as abroad (where citizens voluntarily registered can vote for the resident). Security, durability and handling easiness are some of the characteristics of the Brazilian electronic ballot box, which makes possible the nearly immediate counting of votes.Brazil has been phasing in biometric elections for some time now, with the goal of nationwide adoption of biometrics for elections in 2018.
Balloting security being one of the pillars of a truly democratic system, the Brazilian electoral justice has remained committed to the continued improvement of electoral processes and technologies. For instance, biometric ballot boxes were introduced for over seven million registered voters during the municipal elections. This feature should be extended to the entire country by 2018, an ambitious objective, bearing in mind the always increasing number of registered voters.
