The measure applies only to e-voting machines such as touch-screen, lever-voting and optical-scanning systems. It would not affect punch card systems, paper ballots, or mail-in and absentee ballots.
Called the Voting Integrity and Verification Act, the bill says states must allow the "voter to review an individual paper version of the voter's ballot before the voter's ballot is cast and counted." The paper ballot, typically viewed under glass, would become a "permanent paper record" that must be preserved in case of a recount.

Computer scientists such as those represented by the Association for Computing Machinery have flagged potential security problems and haveelectronic voting machines to produce a "physical record." The Information Technology Association of America has opposed mandatory paper trails.
