I had a couple including one USB one that I later modified to use to scan regular bar codes.
I pulled up Wikipedia to look up who created them, and apparently he changed his name after they failed. He was also on Curse of Oak Island searching for gold and was involved in ballot shenanigans in the 2020 US presidential election where he was notable for supposedly inventing a machine to find bamboo fibers on ballots.
My grandpa had like 3 of these and I never knew what for or why. I guess that explains it!

Yeah, I made this one 1st, but realized that there were probably others who would appreciate the info so I made it a top level comment too.
