Brazil is one of the only countries in the world where the voting process is entirely electronic. The migration to the electronic process starts, with about 70 million voters re-registering with the government to be included in the new voter database. This image shows one of the members of the IT team at Brazil's Superior Electoral Tribunal, who was responsible for the data entry, which took place between 1985 and 1986. 

Following the data gathering of all the voters, election results were processed through a central mainframe at the Brazilian Superior Electoral Tribunal for the first time ever in 1994, however the voting machines were yet to be introduced. 

Voting in Brazil is compulsory; the image above shows a document that all citizens must have in order to vote.  

The government procured the first e-voting machine in 1996. Within a few months, the  first model of the voting device was produced and processed about a third of all voters in the presidential elections that year.

The image above shows the model employed that year. IBM, Procomp and Unisys were involved in the tendering process for the e-voting machine. Unisys won the tender, with a design that was used as a principle for all the other versions of the machine that followed. 

In 1998, two thirds of all Brazilian voters did so electronically in the general elections that took place that year, with 537 municipalities across the country using the method to vote. Local supplier Procomp provided the voting machines for the locations where the number of voters exceeded 40.000 people. 

In 2000, All Brazilians used the electronic method to vote.  That year, the method was used in all the 5.559 municipalities in Brazil that existed back then. Supplier Procomp — acquired by US ATM manufacturer Diebold in the prior year — manufactured 190.000 machines that were used for the occasion.

Biometric registration begins as part of a progressive migration to a new voting identification system. By this year, approximately 14 million out of 140 million Brazilian voters were signed up for the platform. Incumbent manufacturer Diebold was also chosen to provide the new versions for the machines.
