The ministers have decided not to allow the Election Commission to introduce Totaliser voting machines, which make it difficult to learn how an area voted by scrambling data from polling booths.
The Election Commission has been planning for over a decade to introduce the machines. The government, however, has been against it because it argues it will hamper polling booth management.
Before the EVMs or Electronic Voting Machines were introduced in the 1980s, ballot papers on which people cast their votes were jumbled up to ensure even more secrecy and make it difficult to detect a voting pattern.
The totaliser helps connect all EVMs through a cable so votes from a constituency are registered and counted together.
The Election Commission had discussed introducing the Totaliser with all national parties and most accepted it.
