It’d therefore be up to the voter to tell other folks what their number was.

That's the weakness, right there. If someone is going to go so far as to coerce or indimidate someone into voting in a particular way, forcing the voter to divulge their identification number is hardly going to be much of an obstacle.

This can be averted by downloading the data and picking a number that voted the way the intimidator wanted.

Voter intimidation is also a crime that the victim can report.

It’d still be worth it to me to ensure the integrity of the election, which is what I think this would do.
