I wouldn't mind putting initials on every page with print and signature at the end of a ballot just like i'd have to for any legal contract.

Heck if we even get something like voter ID putting that voter registration number on every page of a ballot seems fine too, even if the number is some sort of scannable grid like when we did standardized test in school back in the day and put our name in like that for the machine to read. ( filling in bubbles for letters on a big grid. )
