Texas

Paper ballots are auditable. Fully electronic means are not.

In my county we have a screen to make our choices that prints out a human readable paper ballot that we then walk to the scanner.

This gives us the speed and reliability of voting machines with an auditable paper trail. Williamson County is a step down from that because humans can make errors in marking so it depends on what precise marking method they are using.

While humans may make errors, the audit will reveal that. But without paper there is no audit.
