My mom put her ID in the slot and was given a voting card and when the card was inserted the machine said the card had already cast a ballot. She asked the worker who gave her a new card, and the machine then said unable to read card. This happened three times. The poll manager had to do who knows what to a card to get it to work. While we were at the polling location the same thing happened to several other people. These machines are laughably weak. How am I supposed to know what the QR code the printed sheet reads?
