São Paulo subway will start using facial recognition

Used by more than 4 million people each day, the São Paulo subway’s west-east Red Line will soon start using facial recognition technology to better monitor its stations. The information was confirmed by Governor Rodrigo Garcia, while inaugurating the new electronic monitoring system at the subway’s operational control center.
