An Electronic Voting Machine or an EVM is an essential part of Indian democracy. The EVM allows the voter to cast their choice or choose the NOTA option. To make an informed choice, every voter must know how an EVM works. An EVM Machine demands basic knowledge of identifying the desired political party’s symbol and the local candidate representing it.
An EVM does not require a ballot box, but rather offers an option to simply press a button. It has two units a Control Unit and a Balloting Unit. While the Control Unit remains with the Presiding Officer or a Polling Officer, the Balloting Unit is placed inside the voting compartment. The Polling Officer in charge of the Control Unit presses the Ballot button provided on the Control Unit for releasing the Ballot for the Voter. It enables the voter to cast his/her vote by pressing the Candidate button (Blue color button) on the Balloting Unit against the Candidate and symbol of his/her choice.
Voting is remarkably easy with an EVM since it requires pressing the button against the candidate of your choice. EVMs have also become a site of political battles with allegations of the machines being tampered flying thick and fast among political parties. Some constituencies use a second line of verification in the form of VVPAT machine or Voter Verifiable Paper Audit Trail which allows the voter to check whether their vote has gone to the right candidate or not.
An EVM machine can be assumed to be working normally if a tiny red light glows against the name and symbol of the candidate for whom the vote has been cast. At the same time a long beep should be heard, thus confirming the vote polled.
