Engineer Mr. Rangarajan was invented the Electronic Voting Machines ("EVM") are being used in Indian General and State Elections to implement electronic voting in part from 1999 elections and recently in 2019 PM elections held in different states across India

EVMs have replaced paper ballots in local, state and general (parliamentary) elections in India. There were earlier claims regarding EVMs' tamperability and security which have not been proved. After rulings of Delhi High Court, Supreme Court and demands from various political parties, Election Commission decided to introduce EVMs with voter-verified paper audit trail (VVPAT) system. 

The VVPAT system was introduced in 8 of 543 parliamentary constituencies as a pilot project in Indian general election, 2014. A voter-verified paper audit trail (VVPAT) and EVMs are now used in every assembly and the general election in India. On 9 April 2019, Supreme Court of India gave the judgment, ordering the Election Commission of India to increase VVPAT slips vote count to five randomly selected EVMs per assembly constiteuncy, which means Election Commission of India has to count VVPAT slips of 20,625 EVMs in 2019 General elections.


The control unit is with the presiding officer or a polling officer and the balloting Unit is placed inside the voting compartment. The balloting unit presents the voter with blue buttons (momentary switch) horizontally labeled with corresponding party symbol and candidate names. 

The Control Unit, on the other hand, provides the officer-in-charge with a "Ballot" marked button to proceed to the next voter, instead of issuing a ballot paper to them. This activates the ballot unit for a single vote from the next voter in the queue. The voter has to cast his vote by once pressing the blue button on the balloting unit against the candidate and symbol of his choice.


The cost per EVM was ₹5,500 (equivalent to 44,000 or US$610 in 2018) at the time the machines were purchased in 1989–90. The cost was estimated to be ₹10,500 (equivalent to ₹13,000 or US$170 in 2018) per unit as per an additional order issued in 2014.

Even though the initial investment was heavy, it has since been expected to save costs of production and printing of crores of ballot papers, their transportation and storage, substantial reduction in the counting staff and the remuneration paid to them. 


For each national election, it is estimated that about 10,000 tonnes of the ballot paper is saved. EVMs are easier to transport compared to ballot boxes as they are lighter, more portable, and come with polypropylene carrying cases. Vote counting is also faster. In places where illiteracy is a factor, illiterate people find EVMs easier than the ballot paper system.

Bogus voting is greatly reduced as the vote is recorded only once. The unit can store the result in its memory before it is erased manually. The battery is required only to activate the EVMs at the time of polling and counting and as soon as the polling is over, the battery can be switched off.
