i am not sure how they can identify specific voter ID?
I think these are ballot numbers, SO the ballots are being reproduced!!
Doing a quick search, it's a bit difficult to get a definative answer, but it looks like the Michigan "Voter ID" number is assigned to a person when they register to vote.
Some more info here:
QVF Record Identifying and Voter ID Numbers(July 10, 2023)Some individuals have claimed that the fact that there are multiple identifying numbers corresponding to voter records in QVF suspicious. In reality, there are multiple numbers for security reasons. Voters have a public voter ID number in QVF and the EPB, which is public and disclosed in public record requests. QVF also contains separate record-identifying numbers that correspond to voter records, which are used for security and verification purposes (and which are not publicly disclosed for security reasons). Again, the non-disclosed record-identifying number is not different from the voter ID number for some nefarious purpose, but as an internal verification and security measure.
