There are high resolution cameras over every workstation. Those are monitored by supervisors off to the side. So they cannot skip or alter ballots as they go. This is still a way, way, way, better setup than anything in a vote counting center.
The people doing the work are the regular employees of Cyber Ninjas and three other companies. The UV scanning is an automated process. There is no human judgement to be made by a human. At least that is my understanding. All they have to do is place the ballot on the device and scan it. The program, designed by Jovan Pulitzer makes the determination. This is done three times per ballot.
Thank you for the clarification. Do we have links to the high resolution cameras?
