Explanation:

• Voter-verified paper audit trail (VVPAT) is a method of providing feedback to voters using a ballot less voting system. VVPAT is intended as an independent verification system for electronic voting machines that allows voters to verify that their votes are cast as intended and can serve as an additional barrier to changing or destroying votes.
