What is electronic voting machine and how its work?

What is EVM? Perhaps many people in your EVM will also have to vote. But do you know what exactly is this Electronic Voting Machine and how does it work? If you do not know the answers to these questions, then this article from today is of course very interesting to you. That’s because today we will understand everything about voting machines and everything related to it.

There is always some news about the EVM that is essentially in Akbar. Although this is a very useful thing, many political parties have questioned many times about its security. That is why it has become very important that we too have some knowledge of this electronic voting machine. This will make it easier for us to understand this and how it works. That’s because many have questioned this, so the Election Commission has thought of using new and advanced EVMs till the coming 2019 election. So today I thought why you should be given full information about what happens to the electronic voting machine and how it is used so that you will be able to understand it better. So let’s begin without delay.

What is the electronic voting machine (EVM)?


The full form of the EVM is Electronic Voting Machine. This is a machine so that any voter can give his opinion to any political party. In this machine, separate buttons are assigned for different representatives, which also has the symbol of that party. And all of these are connected via the electronic ballot box via a cable.

An EVM consists of two units – control unit and balloting unit – these two are connected to each other through a five-meter cable. When a voter presses a button that is of a candidate, then the machine locks itself in such a manner.

In this case, a new ballot number is required to open the EVM. Otherwise, it can not be opened. This protects the fact that EVMs make sure that a person can only vote once.

History of EVM machine

In 1980, M.B.Haneefa invented the first Indian Voting Machine, it was named after that gazetted “Electronically Operated Vote Counting Machine”. The original design made by him was first exhibited to the public in nearly six major cities of the country.

EVMs were officially commissioned by the Election Commission of India in 1989 when it collaborated with Bharat Electronics Limited and Electronics Corporation of India Limited. Industrial designers of EVMs were from IIT Bombay’s Faculty members of the Industrial Design Center.

EVM machine first used in India by an election in Kerala. After that, on an experimental basis, it was used in some selected constituencies of Rajasthan, Madhya Pradesh, and Delhi.

EVMs were used for the first time in the general elections of Goa (the entire state) in 1999. By 2003, EVMs were used in all by-election and state elections. Later, in 2004, the Election Commission decided to use EVMs in Lok Sabha Elections.

Now let us know that some of the special features of the EVM that you may not know about

1. It is absolutely free of tampering and it is also very easy to operate.

2. It has been programmed in such a way that once you have voted in it, you can not give the same vote as the second vote. Programs that control the functions of the control unit are destroyed in a “once programmable basis” microchip. Once destroyed, it can not be read, it can not be copied or there can be no change.

3. In it, the Steve Microchip is designed in such a way that after it has been programmed once it is used only in one task, no change can be made in it, no copy can be made in it. is. That’s why it is very safe with security.

4. The possibility of illegal votes in EVM machines is very less.

5. It calculates faster in the calculation process and decreases the printing costs.

6. Since the EVM machine operates with a battery, it can be easily used in non-power areas.

7. If the number of candidates is not more than 64 then elections can be done using EVMs in such places.

8. In an EVM machine, a maximum of 3840 votes can be filed.

What is EVM’s Design and Technology?

An EVM consists mainly of two units, the control unit, and the balloting unit. These two units are connected by a five-meter cable. Where Balloting unit is used primarily by a voter, it is done through the labeled buttons to give voting to control the ballot units using the same control unit, which stores the voting counts and finally results to A 7 segment shows in LED displays.

The controller used in EVMs has its own operating program, which has been permanently etched in silicon by the manufacturer during its manufacturing. Therefore, no one even producer can change that program once the controller is manufactured.

EVMs are powered by an ordinary 6-volt alkaline battery, which is manufactured by Bharat Electronics Limited, Bangalore and Electronics Corporation of India Limited, Hyderabad. Therefore EVMs of this design can be used anywhere in the country where there is no facility of the power supply.

Maximum 3840 votes can be recorded in an EVM and it can handle up to 64 candidates. In this case, there is the provision in only one balloting unit for only 16 candidates and the maximum of 4 units can be connected in parallel. Where the number of candidates is more than 64, the conventional ballot paper/box method is used only for polling.

In this one candidate can not give more than one vote, and if so many times press that voting button. As soon as a candidate presses a particular button in the balloting unit, then that vote automatically gets recorded for that particular candidate and then the machine automatically gets locked up.

Therefore, whenever any button is pressed after that, then no vote is recorded for the same candidate. Similarly, EVMs ensure that the principle of “one person, one vote” is maintained.

Which big personality is behind the development of Electronic Voting Machine?

The main reason behind the whole development of these electronic voting machines was the hand of two people: S. Rangarajan and T. N. Swamy.

Why is a voting machine used in India?

These electronic voting machines are being used in India since 1999. By the way, the use of EVM also means that away from the paper ballots, and thus preventing lakhs of trees from being cut off.

It is making the whole voting process easy, it just has to press a button and your vote gets registered.

EVMs are used if we think long-run, then it is going to be very cost-effective. By the way, its initial cost was slightly more than Rs 5,000 to Rs 6,000 for each machine, although it has been used comfortably for nearly 15 years.

These machines do not require electricity to run and they can run in batteries. These EVMs are very light and portable if we compare them with large ballot boxes.

Apart from this, the use of EVMs has now become very fast in the voting-counting process, where votes counting took many days and now the votes are counted within a few hours.

How to use an electronic voting machine?

It is very easy to use EVM. In the EVM’s control unit booth’s presiding officer or polling officer, the balloting unit is placed inside the voting compartment. In that balloting unit there are blue buttons and horizontally labeled before they are corresponding party symbol and their names.

At the same time, the Control Unit provides the office in-charge of that booth so that they control a “Ballot” marked button so that the next voter can go inside to vote. Where the first one ballot paper was used to issue. This happens because it allows the ballot unit to vote next, which is standing in the queue.

In this, the voter has to press the blue button in front of the front to cast his vote in that balloting unit and for this, he can take help of the candidate and his symbol in front of it.

As soon as a voter votes, then the Polling Officer in-charge presses the ‘Close’ button of that Control Unit. EVM is locked up before such a move, before taking the next vote. After the further poll is closed, the Balloting Unit is disconnected from the Control Unit and kept separately. Votes are recorded by the Balloting Unit.

When polling ends, then the Presiding Officer is given the account of votes to all the polling agents in that booth, for the counting. When counting of votes is done, then total votes are collected and if any discrepancy occurs then those Counting Agents bring that mistake to the presiding officer.

Well, during the counting of votes, the results can be easily displayed through the ‘Result’ button. There are two safeguards, which can be prevented from pressing the ‘Result’ button until votes counting starts officially.

(a) This button can not be pressed unless the ‘Close’ button is pressed by the Polling Officer in-charge by the same polling booth.

(b) This button is kept hidden and sealed; And this seal is opened only in the counting center, in the designated office in the presence of everyone.

Benefits of Electronic Voting Machines

Now let us know about some of the advantages of EVM.

  • Even though the initial cost of EVM is slightly higher, but if we think for long-term then these are very cost effective.
  • Its use has prevented many trees from cutting, which were used for ballot system.
  • The battery is used in it so it can be used anywhere.
  • It is very light, so it can be easily taken anywhere.
  • Compared to Ballot Voting, there is no cost to use.
  • Counting of votes in this is very easy and soon
  • Illiterate people can use it much better.
  • There is very little chance of manipulating voting and problems like burglary is also less.

EVM machine disturbances

In the time of 2009, BJP’s political leader L K Advani first questioned the security features of electronic voting machines. Later Subramanian Swamy filed a petition in this matter regarding the Delhi High Court in which he challenged the current form of EVMs and used it. The court did not do much about this subject nor did the directive to the Election Commission.

Then Subramanian Swamy approached the Supreme Court in October 2013, in which he made the decision that the Election Commission will now use the Voter-Verified Paper Audit Trail (VVPATs) which will be linked in the phased manner with EVMs and it will be completed by 2019. Will be brought in.

When brought to VVPAT (EVM and VVPAT)

When so many questions were raised about the security of EVMs, the Election Commission appointed a committee whose main task was to link EVMs with a paper trail machine so that voters could get a slip-proof of which party they voted. With this, a voter can check their vote immediately after voting.

This Voter-Verified Paper Audit Trail (VVPAT) was first used in the Noksen assembly constituency of Nagaland in 2013.

In the recent Assembly elections, the Election Commission used this VVPAT system in all the constituencies of Goa. The same voter-trail system was used only in a few constituencies such as Uttarakhand, Uttar Pradesh, Manipur, and Punjab.

When is the ADVANCED M3 EVMs ahead to be introduced?

Since many political parties have raised their finger on EVM’s tamper-proof, Election Commission is going to launch an advanced version of EVM very soon, before the 2019 election.

According to the reports, these new advanced EVMs have been developed in such a way that they will stop working if someone tries to tie them.

These new M3 EVMs will have their own public key interface (PKI) -based mutual authentication between different EVM units so that they can identify a genuine unit, in which they can only allow genuine EVMs. To within the network.

By the way, these EVMs will remain the same, if we talk about the operation then In this, just technologically some advancement may appear.


I hope that you have a choice of what is EVM in Hindi, this article is my electronic polling machine (EVM). My always efforts are to keep readers informed of the EVM machine so that they do not need to find any other sites or internet in the context of that article.

This will also save their time and will get all the information in one place. If you have any doubts about this article in your mind or you want some improvement in it then you can write down comments for it.
