Brazil combines compulsory voting for most adults with a fully electronic in-person ballot. Voters identify themselves at a polling station, often biometrically, and use a standalone voting machine. Each machine produces a signed ballot bulletin after polls close; those records can be compared with published totals and were central to the independent checks after the close 2022 election.

Standalone machines are prepared through public technical ceremonies and tests. After voting, each machine prints a signed ballot bulletin containing totals but no voter choices; parties, inspectors and citizens can compare those bulletins with electronic publication. The 2022 TCU audit found no divergence in the sampled comparisons and integrity tests it performed.
