    en.wikipedia.org/wiki/OCR-A

    OCR-A is a font issued in 1966 [2] and first implemented in 1968. [3] A special font was needed in the early days of computer optical character recognition, when there was a need for a font that could be recognized not only by the computers of that day, but also by humans. [4] OCR-A uses simple, thick strokes to form recognizable characters. [5]
