Voter-verified paper audit trail
Voter verifiable paper audit trail (VVPAT) or verified paper record (VPR) is a method of providing feedback to voters using a ballotless voting system. A VVPAT is intended as an independent verification system for voting machines designed to allow voters to verify that their vote was cast correctly, to detect possible election fraud or malfunction, and to provide a means to audit the stored electronic results. It contains the name of the candidate and symbol of the party/individual candidate. While it has gained in use in the United States compared with ballotless voting systems without it, it looks unlikely to overtake hand-marked ballots.

A voting machine is a machine used to record votes in an election without paper. The first voting machines were mechanical but it is increasingly more common to use electronic voting machines. Traditionally, a voting machine has been defined by its mechanism, and whether the system tallies votes at each voting location, or centrally. Voting machines should not be confused with tabulating machines, which count votes done by paper ballot.
