Cletus, on the subject of election fraud; a person could use an RFID tag attached to their ballot. If several persons attached RFID tags and tracked their ballots this device could show illegal activity.
Here’s a website that sells various rfid tags:

Good idea but, would attaching anything to a ballot be illegal?
