The machines we use (DuPage County, Illinois) create a paper trail that backs up the electronic tabulation with a printed record similar to a grocery store receipt. But then, DuPage county is a strong Republican area and is known for honest elections.
The voting machines in Clark County, NV also create a paper trail similar to a grocery store receipt. The voter does not get a copy, but they do get to view their votes before pushing the final button to confirm and cast their ballot.
Of course, if election officials want to conduct honest elections they can and will do it. It’s not a technology issue; it’s a dishonesty issue.
