The U.S. Election Assistance Commission (EAC) has certified the Unity 3.2.1.0 voting system by Election Systems and Software (ES&S) to the 2002 Voting System Standards. It is the fifth voting system to achieve federal certification under EAC’s Voting System Testing and Certification Program.
The Unity 3.2.1.0 comprises two precinct-based optical scanners—the M100 and the DS200—and one central-count scanner, the M650. The accessible voting device for this system is the AutoMark. EAC issued federal certification for the Unity 3.2.1.0 system after ES&S demonstrated compliance with the following final certification requirements, which complete EAC’s comprehensive testing process: rebuild the voting system in a trusted environment, known as a “trusted build” (an act performed by an EAC-accredited test lab), provide software identification tools to EAC so that whomever purchases the system can verify its authenticity, provide voting system software for the EAC repository, and agree in writing to comply with all EAC certification conditions and program requirements.
