In preparation for the 2020 presidential election, six states have replaced, or are on track to replace, their paperless voting machines, but eight others still plan to use some machines that do not have paper backups. Paper-based systems are considered more secure than paperless ones because they are less susceptible to cyberattack and because election officials can audit the returns for accuracy.
