In a letter to all chief electoral officers, the poll panel has said that "as the Commission has decided to use VVPAT in all the future elections, no relaxation /deviation will be allowed in the upper limit of 1200 and 1400 electors in rural and urban polling stations respectively.

The voter verified paper audit trail is a machine which dispenses a slip with the symbol of the party for which a person has voted for. The slip drops in a box but the voter cannot take it home.
The voters see voter-verifiable paper audit trail slip for seven seconds, which would be an acknowledgement receipt for the party they voted for in the election.
As voters watch to see the paper slip appear in a window, they may spend additional few seconds in the voting compartment. If there are large number of voters, the overall time to cast the vote may go up.
