Polity : Electronic Voting machines in India

  • The EVMs were devised and designed by Election Commission of India in collaboration with two Public Sector undertakings -  Bharat Electronics Limited, Bangalore and Electronics Corporation of India Limited, Hyderabad.
  • EVMs were first used in 1982 in the by-election to Parur Assembly Constituency of Kerala for a limited number of polling stations (50 polling stations).
  • EVMs can record a maximum of 3840 votes. As normally the total number of electors in a polling station will not exceed 1500, the capacity of EVMs is more than sufficient.
  • EVMs can cater to a maximum of 64 candidates. There is provision for 16 candidates in a Balloting Unit.Upto 4 EVMS can be connected together.In case the number of contesting candidates goes beyond 64 in any constituency, EVMs cannot be used in such a constituency. The conventional method of voting by means of ballot box and ballot paper will have to be adopted in such a constituency.
  • The most important advantage is that the printing of millions of ballot papers can be avoided which results in huge savings by way of cost of paper, printing, transportation, storage and distribution. Secondly, counting is very quick and the result can be declared within 2 to 3 hours as compared to 30-40 hours, on an average, under the conventional system. Thirdly, there are no invalid votes under the system of voting under EVMs.
