The companies offer a variety of products, including optical scanners, ballot marking devices and direct recording electronic systems.
Greg Miller is the co-founder and COO of the OSET Institute–a non-profit working to improve voter technology. According to Miller, the machines currently in use are vulnerable to hacking.
