Voter Verifiable Paper Audit Trail (VVPAT) machines are used during election process to verify that the vote polled by a voter goes to the correct candidate. VVPATs are a second line of verification and are particularly useful in the time when allegations around Electronic Voting Machines’ tampering crop up. Parties have been making regular demands for VVPATs to be used during elections after alleging EVMs may not be completely secure and tamper proof.
VVPAT system gives instant feedback to the voter showing that the vote polled has in fact been allotted against the candidate chosen.
Working procedure of VVPATs
After a voter presses the button on the EVM against the chosen candidate, the VVPAT prints a slip containing name of the candidate and the election symbol and drops it automatically into a sealed box. The machines give the chance for the voter to verify their vote. The machine is placed in a glass case in a way that only the voter can see it. The slip is displayed to the voter for seven seconds after which the VVPAT machine cuts it and drops in into the storage box with a beep. The machines can be accessed, though, by the polling officials and not by the voter.
The Election Commission of India has not conceded to any allegation that the EVMs used for polling can be tampered with. However, VVPATs have been used in some elections in a bid to counter all allegation of tampering.
The Supreme Court of India, meanwhile, has for long held a supportive and extra cautious stand when it comes to voting. It had directed the EC in 2013 to introduce VVPAT in Lok Sabha Elections 2014 to improve voter confidence and ensuring transparency of voting. It was used in some phases but not in the entire polling process.
