    How does Electronic Voting Machine (EVM) function?

    Wondering how an EVM functions and decides the fate of a contestant! Let us have a quick look here to know what our experts say about this.

    After the announcement of results of recently held Assembly elections in five states, many political leaders and their sidekicks are questioning about EVMs. However, I am not going into that issue. My questions relating to EVMs are as follow:-

    (a) On what principle does the EVM function?
    (b) Which country did use EVM first?
    (c) Does EVM function where there is no electricity?
    (d) How can the votes in an EVM counted?

    Electronic voting machine manufactured in 1989 to 1990. To run this machine electricity does not require. EVMs machines run on an ordinary 6 volt battery. this machine record maximum 3800 votes. A machine can only accept 5 votes in a minute and after each vote, machine locks itself and can only be unlocked using a new ballot number. this ballot number is the component of EVMs.
    firstly this machine introduced in madhya pradesh, rajasthan,delhi.
    EVMs machines are combinations of two components first is balloting unit and second one is control unit. this two units are connected by five meter cable. ballotting unit on which the voters press the button and control unit gives supervising power to the polling officer stationed at the poll booth.

  • Here are some of the answers for your questions.

    1. EVM machine makes use of the principle that chosen option gets recorded with respective voter ID. Some machines are neutral to the voter ID and only record the vote.
    2. EVM machines earlier used to depend on the electricity but these days they are powered with 6V battery.
    3. EVM first invented by Haneefa in India in October 1980 and then it was used in 6 cities of Tamilnadu state. Later with import from other countries, the machines were calibrated and modified for better changes.
    4. EVM in some countries are centralized and they count the vote lot quicker.
    5. EVM counts the vote against the available set of option. Think of it like stack games of kids. The one with more stacked rounds wins. EVM too counts the vote towards the candidate with more stacks. At the end of the day, the polling supervisor presses the close button to stop the vote. Earlier these machines had limitations to count 3000 votes per machine till reset. Now the EVM are calibrated to be counting votes only on the basis of population limit set by the region.

  • 1.Brazil was first who used publicly electronic voting in 1996 for municipality elections.
    2. India EVM uses "One Person One Vote" principle of voting. Once vote it captured it blocks button from making more entries until polling both officer release lock for next voter. While counting the seal of result button is broken in front of higher officers of election panel. Count is tallied with manual count of people voted.
    3. EVM functions without electricity on batteries.
    4. Counting of votes are done per unit of voting machine. Once result ready , it will be noted by officer in charge. These steps repeated until all voting machine counts are taken from all part of constituency. At the end total results will be declared.
    This counting is manual and to reduce human error now technology is working to publish live results of vote counting in assembly or parliament by connecting result to central system. It will be one click result for all voting units.
