What is Electronic Voting Machine?

• EVMs or electronic voting machines provide the voter with a button for each choice which is connected by a cable to an electronic ballot box.
• An EVM consists of two units--control unit and balloting unit--and these two are connected by a five-meter cable. When a voter presses a button against the candidate he/she wishes to vote for, the machine locks itself.
• This EVM can be opened only with a new ballot number. This way, EVMs ensure that one person gets to vote only once.

WHY is India using EVMs?

• Electronic voting machines have been in use in India since 1999. Using EVMs means doing away with paper ballots, and in turn, saving millions of trees from being cut.
• It makes the entire process of voting simpler--a click on the button and your vote is registered.
• EVMs, in the long-run, have turned out to be cost-effective as well. Although the initial cost of an EVM is between Rs 5,000 and Rs 6,000, the machine, on an average, lasts for 15 years.
• These machines don't require electricity and run on batteries. At the same time, the EVMs are lighter and portable compared to the huge ballot boxes.
• And most importantly, EVMs have made the vote-counting process much faster, delivering results in hours as against manual counting of votes which could take days.
