Technology specialists and watchdog groups have denounced the move because the devices are vulnerable to hacking that could change the results embedded in the barcodes. They say Georgia should follow the example of other states in adopting the most secure voting technology on the market — scannable paper ballots that voters mark with pen or pencil.
Raffensperger and his staff have rejected the experts’ advice, arguing that the barcode machines are more convenient for voters used to the state’s existing paperless touchscreen machines.
Raffensperger, who has no computer science or cybersecurity experience, has responded to the criticism by trying to brand experts who disagree with him as radical. In a radio interview, he said that “anyone that believes in hand-marked paper ballots” — a group that includes the National Academies of Sciences, Engineering and Medicine and many of the country’s leading voting security researchers — is “out of the mainstream.”
Marks called this charge “a pathetic attempt to deflect from his planned absurd waste of money on bad technology and to ensure that Georgia’s elections remain unauditable.” [Source]
