Voter rolls are public information in the US; there are several watchdog groups that perform verification services and have done so for decades; and to date, none have uncovered the kind of large-scale voter fraud that would necessitate doing anything differently from what we do now.

In fact, I'd argue that having 50 different voting systems with 50 different ways to prove eligibility makes our elections more resilient to large-scale voter fraud, even if it makes it more difficult to verify voter rolls wholesale.
