At Gateway Pundit is an article explaining the techniques for validating ballots used in 2020 elections Maricopa County Auditor Bob Hughes Shares How They Are Using High Tech Forensic Digital Cameras and OCR to Validate Ballots. Excerpts in italics with my bolds.
Any massive vote fraud in Maricopa County Arizona is going to be identified. The Democrats must be terrified.
One of the auditors working for the Arizona Senate, Bob Hughes, discussed the audit and the reasons why the Democrats are absolutely frightened of the Arizona audit and it being performed in other states:
The other thing that I think is interesting is they keep saying, ‘They don’t know what they are doing’. ‘They’re idiots’. ‘These people are ridiculous’. ‘They have no idea what they are doing’. ‘They’ve never done this before’.
This is the first time in the history of the United States, number one, that it’s ever been done, but more important it’s the first time it’s ever been needed. And it was done.
I can tell you that I could go over all the process and you’d all understand, but when a ballot gets created, think about this. It’s like your bill being paid from SRP. They go out and get your voter identification number and they find out what precinct you live in, what city, what county, where your school districts are. All that information has to be accessed to create the proper ballot exactly for you. Because you have to vote for the right candidates in a city mayoral election, council elections, JP elections, the legislative district, the congressional district. [In fact, in 2020 there were 667 different versions of Maricopa County ballots.]
Think of those as maps that overlay the Maricopa County area and it creates all these little sections, and all these people get a very different ballot. So if somebody did what we were told they might have done, which is gone out and just duplicate a bunch of ballots, or put the same ballot in many times, or any of these kinds of things, I knew there was a way to find that out.
And so what we did is we, the cameras are not only cameras. They’re digital cameras. Digital cameras that are forensic. They’re actually police forensic cameras. They’re very, very high speed, high definition digital cameras. They make a scanned ballot.
So we scan that ballot. We then use optical character recognition (OCR). We’re looking at what’s in place on that ballot. Based on who that ballot is. How many should be? Can there be this many?…
…What I can tell you is you now will have the most authentic count of every legal authentic ballot you could possibly have.
