Electronic Voting Machines (EVMs) are used extensively in India since 2000 to record votes in elections.

EVM Structure

An EVM includes a thick, rectangular device used to electronically record votes cast in elections.

Voting Process

Voters press a blue button against the serial number, name, and symbol of their chosen candidate.

EVM Units

An EVM has three units - a ballot unit, a control unit, and a voter-verifiable-paper-audit-trail (VVPAT) unit.

Privacy Ensured

The control unit is placed next to the officer-in-charge while the other two units are kept in a voting compartment.

No External Connectivity

The whole setup is without any wired or wireless connectivity outside the system.

Votes and Candidates

Each ballot unit can include 16 candidate options. One unit can cater up to 384 candidates.

EVM Capacity

An EVM system, which can record up to 2,000 votes, runs on battery or power-packs supplied by its makers.

EVM Cost

The whole setup costs nearly ₹34,000 ($408) and can work for about 15 years.

EVM History

EVMs were first used in India for a by-election to the Parur assembly seat of Kerala in 1982.

EVM Controversy

The Election Commission says the paper slips can be used to verify the electronic vote count in case of a dispute.
