Ever wondered why electronic voting machines, used in four Lok Sabha elections and 127 assembly polls since 2004, are not deployed in polls to elect the President and Vice President of India, members of the Rajya Sabha, and members of state legislative councils? The EVMs are based on a technology where they work as an aggregator of votes in direct elections such as the Lok Sabha and state assemblies.
Voters press the button against the name of the candidate of their choice and the one who bags the maximum number of votes is declared elected.
