There used to be a separate printer attached to the voting machines, which would print each individual vote, in the presence of the voter, and would automatically go into a ballot, and it would be used in case there was an allegation of fraud. They of course did the dumb thing and did away with the printer, now they only have printouts of the total votes after the session is done and the machines are about to leave the place. From Wikipedia: "The 2002 version had a printer module that printed each vote, but the printed vote was abandond after Law 10.740/2003 and should only be reintroduced in 2014, according to Article 5 of Law 12.034/2009"
