The Supreme Court said that it will hear a batch of pleas seeking cross-verification of the votes cast with Voter Verifiable Paper Audit Trail (VVPAT), on April 16.
VVPAT device functions like a printer to be attached to the ballot unit (EVM - Electronic Voting Machine).
The VVPAT is an independent vote verification system which enables an elector to see whether his vote was cast correctly.
It generates a paper slip which can be viewed by the voter. It is kept in a sealed cover and can be opened in case of a dispute.
For the first time VVPAT with Electronic Voting Machines was used for the Noksen Assembly seat in Tuensang district of Nagaland in September, 2013.
