Brazil's Election Court Did Not Train Poll Workers to Spot Smart Glasses Before Vote

Smart glasses with built-in cameras are barred from Brazilian voting booths under rules meant to protect ballot secrecy, but the manuals used to train the roughly half a million citizens who staff polling stations do not mention the devices by name, according to reporting reviewed for this piece.

On Friday, October 2, two days before the first round of the 2026 general election, the consumer-rights group Idec (Instituto Brasileiro de Defesa do Consumidor) and the digital-rights organization Instituto Coding Rights sent a formal letter to TSE president Minister Kassio Nunes Marques asking the court to reinforce enforcement of the existing ban before voters went to the polls on Sunday, October 4, Mobile Time reported.

What the existing rule says

TSE Resolution No. 23.751/2026 prohibits voters from carrying cellphones, cameras, video cameras, radio-communication equipment or 'any other instrument that could compromise the secrecy of the vote' into the booth, even if the device is turned off, according to Mobile Time. Separate reporting by iMirante cited Article 137 of the 2026 General Electoral Process Acts as the legal basis barring any device capable of recording how a person votes.

News outlet GC Mais reported that in guidance issued in September 2026, TSE explicitly added 'smart glasses that record images' to a list of banned wearables that already included connected watches and bracelets, body cameras and microcameras. iMirante reported that a voter who refuses to hand over a prohibited device cannot vote at that time.

The training gap

Despite that September clarification, outlet ClicRDC reported that smart glasses do not appear specifically in the manuals or training materials given to poll workers for the current election or the previous three elections it reviewed. The same manuals do expressly list digital or smartwatches among prohibited equipment, the outlet said, creating an inconsistency that leaves workers without clear guidance for glasses that can look identical to ordinary prescription eyewear.

Desembargador Roberto Maia Filho, vice-president of the regional electoral court in São Paulo (TRE-SP), told ClicRDC that the procedure for glasses should mirror the one already used for phones.

Fernando Neisser, an electoral-law professor at Fundação Getúlio Vargas (FGV), said updating training and guidance for polling-place workers would be more effective than writing a new rule for each new type of device, ClicRDC reported.

Why the groups are concerned

Idec and Coding Rights told TSE that smart glasses can look almost identical to conventional eyewear and that their cameras are difficult to notice, according to Mobile Time. The organizations warned that footage of how someone voted could be used as proof of compliance in vote-buying or coercion schemes, and said responsibility for deciding how to act should not fall on poll workers 'without specific guidance' at the moment of voting, Mobile Time reported.

Brasil em Folhas reported that the letter asked Nunes Marques, as TSE president, to immediately instruct regional electoral courts (TREs) about the risk and to order that any incidents involving the devices be documented on election day. The outlet said one court minister acknowledged the technology remains relatively uncommon in Brazil but voiced concern about scenarios in which recorded footage could be used to prove coercion or vote-buying.

ClicRDC reported a documented precedent from the 2024 municipal election in Ourilândia do Norte, Pará, where voters allegedly received up to R$200 to wear micro-camera glasses and prove how they had voted; the case led to the revocation of the elected councilman's diploma in May 2026, according to the outlet.

Timeline

What the groups want changed

• For the first round: clarify the scope of the existing ban, reinforce it through official TSE channels, and record any incidents in polling-station logs, per Mobile Time.
• For the runoff: set objective criteria to identify smart glasses, define a procedure for voters who wear prescription smart glasses, and clarify rules for devices with microphones or wireless transmission, per Mobile Time.
• Medium term: fold wearable-device restrictions into future TSE resolutions and make them part of mandatory poll-worker training, per Mobile Time.

Brasil em Folhas reported that global smart-glasses sales reached 9.6 million units in 2025 and are projected to reach 13.4 million in 2026, figures the outlet cited to illustrate why the devices are becoming harder for election staff to ignore.

As of publication, TSE had not issued a public response to the Idec and Coding Rights letter, according to the sources reviewed.
