5. Voter-verifiable paper audit trails or records are the paper trails contemporaneously printed by DRE (Direct Recording Electronic) voting machines that display to the voter a hard copy record of the voter’s selections. Sighted voters may use the paper records to verify that the machine correctly recorded a hard copy of his or her selections before casting the ballot. In some states, the voter-verifiable paper record is the legal ballot in a recount situation (e.g., California), taking precedence over electronic counts. Visually impaired voters currently cannot verify a hard copy of their votes when VVPATs are used. VVPAT printers do not currently include optical character recognition (OCR) readouts or other means of non-visual verification of the information printed on the VVPAT. The only way a visually impaired voter can currently verify a paper copy of the ballot through the use of technology, which allows such a voter to vote privately and independently, is by using an accessible ballot marking device to mark the ballot that also enables audio read-back of the voter’s choices from the printed or marked ballot.
