Pactos is the first and only manufacturer of specialized computer and electronic equipment for the visually impaired in Iran. The company was founded in 1991 by a group of graduates from Sharif University of Technology. Since its establishment, alongside its focus on computer engineering (hardware and software), Pactos has been consistently active in designing and producing assistive technologies for the blind community.
