Explanation:

The Government of India informed the amended Conduct of Elections Rules, 1961, on 14th August 2013, enabling the Commission to make use of VVPAT with EVMs. The Commission used VVPAT with EVMs (electronic voting machine) first time in bye-election from 51-Noksen (ST) Assembly www.gradeup.co 14 Constituency of Nagaland. After that, VVPATs have been used in selected constituencies in every election to Legislative Assemblies and eight Parliamentary Constituencies in General Election to the House of the People in 2014. About VVPAT: Voter Verifiable Paper Audit Trail is an independent system that is attached to the Electronic Voting Machines, which allows the voters to verify that their votes are cast as they intended. When a vote is cast, a slip is printed on the VVPAT printer containing the serial number, name, and symbol of the candidate and remains exposed through a transparent window for seven seconds. After that, this printed slip automatically gets cut and falls in the sealed drop box of the VVPAT. VVPAT consists of a Printer and also a VVPAT Status Display Unit (VSDU). However, in M3 VVPAT, there is no VSDU and status of VVPAT display on the Control Unit of M3 EVM. VVPAT runs on a power pack (Battery) of 22.5 volts. Control Unit and VSDU are maintaining with the Presiding Officer or Polling Officer, and Balloting Unit and Printer remain in the voting compartment.
