A significant number of electronic-voting machines in use in Colorado aren't reliable enough nor secure enough for compliance with state laws, the Colorado secretary of state said today.
Coffman announced his office had determined that Sequoia's electronic-voting machines — the Edge II and the Edge II Plus — both failed due to security-risk factors.
He also said the optical-scan devices eScan and BallotNow, manufactured by Hart, showed they could not accurately count ballots.
ES&S optical-scan devices failed as well because of the inability to determine whether they worked properly. That manufacturer's electronic-voting machine, iVotronic, also failed because it can be easily disabled by voters. In addition, that system lacked an audit trail.
