Awesome.

Do you think there's a possibility that most printers/copiers do something like this this?

Maybe able to pinpoint where the fakes came from?
There was a suspicious fire at a printer company in NY (that incidentally printed ballots for 2020). Not sure of the connection, but this video brought back that memory.

Edit; QR code's contain lots of information... IP addresses don't take much space.... gps location data too
