Colorado on Monday became the first state in the U.S. to ban the use of QR codes on ballots, citing cybersecurity concerns associated with the use of these codes in tabulating votes.
Colorado Secretary of State Jena Griswold (D) noted in announcing the change that cybersecurity experts have raised concerns around the security of using the QR codes on ballots.
Griswold also cited findings by U.S. intelligence that Russian operatives attempted to interfere in the 2016 presidential election as a reason to enhance cybersecurity of elections.
