For example, the Avante Vote-Trakker simply counts the number of dark and light pixels in each marking area to determine if the mark counts as a vote.

[4] Optical mark recognition has evolved from several other technologies. In the early 19th century and 20th century patents were given for machines that would aid the blind. [2]
Several other ballot marking devices have come on the market to compete with the AutoMARK.

Voters cannot easily verify that the bar code matches the human-readable print, but in an ...
