- When was the EVM introduced in India?
It was first used in 1982 in the bye-election to Parur Assembly Constituency of Kerala for a limited number of polling stations (50 polling stations).
- What are the unique features of Indian EVMs?
It is a simple machine that can be operated easily by both the polling personnel and the voters. It is sturdy enough to withstand rough handling and variable climatic conditions. Being a stand alone machine without any network connectivity, nobody can interfere with its programming and manipulate the result. Keeping the erratic power supply position in many places in the country, the machines have been made to run on batteries.
- Who manufacture EVMs in India?
The two central govt. undertakings i.e. Bharat Electronics Limited and Electronics Corporation of India Limited are the only manufacturers from whom the EVMs are procured by the Election Commission of India.
- Whether ECI took the advice of technical expert before approving the EVM?
Yes. Before inducting the EVMs, opinion of the Technical Committee comprising Prof. S. Sampath, Prof. P.V. Indiresan and Dr. C Rao Kasarbada was obtained. The Committee examined the machines minutely from all technical angles and unanimously recommended their use in elections.

An EVM can record a maximum of 3840 votes which far exceeds the number of voters (usually less then 1400) assigned to a polling station.
- In some elections large number of candidates contest. What is the maximum number of candidates which EVM can cater to?
Elections can be conducted through EVMs when the maximum number of candidates does not exceed 64.
- What will happen if the number of contesting candidate goes beyond 64?
In such cases poll has to be conducted through conventional method of ballot papers/boxes.
