The Election Commission will introduce Voter Verifiable Paper Audit Trail (VVPAT) countrywide on experimental basis to ensure a fair Lok Sabha poll. The VVPAT is a paper slip which will come out of the Electronic Voting Machine (EVM) once a voter casts his vote, showing which symbol and candidate the vote has been cast for. The slip will be automatically dropped in a sealed box attached to the EVM for use by the EC, Chief Electoral Officer in West Bengal Sunil Gupta today said.
The VVPAT system has already been demonstrated to the representatives of all recognised national and state political parties.
The Commission has placed an order for about 20,000 VVPAT machines and those will be deployed in states selectively depending on their availability.
