Yes. The voting system goes through a rigorous set of tests that are performed by the Independent Testing Authorities (ITAs) - one for the software (source code) and one for the hardware. The ITAs are certified by the Federal Election Commission and follow the Voting System Standards. The ITA tests to ensure that the voting system accurately tallies votes and that the hardware is impervious to destructive handling and magnetic devices. South Carolina receives the executable software directly from the ITA, not from ES&S. In addition to the testing performed by the Independent Testing Authorities, the State of South Carolina conducts tests on each voting unit before it can be certified for use in the State.
