Understanding Electronic Voting Machines (EVMs)
Electronic Voting Machines (EVMs) are crucial components of modern electoral processes, particularly in countries like India. They are designed to replace traditional ballot papers and voting booths, aiming to enhance efficiency, accuracy, and transparency in elections. This module delves into the working principles, evolution, and significance of EVMs in the context of competitive exams like the UPSC.
What are Electronic Voting Machines?
An EVM is an electronic device used for casting votes. It consists of two units: a Control Unit and a Balloting Unit. The Control Unit is with the Presiding Officer or the Polling Officer, while the Balloting Unit is placed in the voting compartment. The Balloting Unit displays the names of the candidates and their election symbols, allowing voters to press a button next to the candidate of their choice. The EVM records the vote cast and prevents multiple voting.
EVMs streamline voting by using electronic means, reducing errors and speeding up the counting process.
EVMs consist of a Control Unit and a Balloting Unit. The Control Unit manages the voting process and stores vote counts, while the Balloting Unit presents the candidates to the voter. They are designed to be tamper-proof and user-friendly.
The Control Unit (CU) is the central component of the EVM. It is operated by the Presiding Officer or Polling Officer. The CU has a display screen, a keypad for entering codes, and a 'Result' button. It is connected to the Balloting Unit (BU) via a cable. The BU contains buttons, each corresponding to a candidate and their symbol. When a voter presses a button on the BU, the vote is registered electronically in the CU. The CU can be switched on only by entering a specific code. It also has a 'Close' button to end the poll and a 'Result' button to display the total votes polled for each candidate. The CU is powered by a battery, making it usable even in areas without electricity.
How EVMs Work: The Process

The voting process begins after the Presiding Officer verifies the voter's identity. The Presiding Officer then activates the Balloting Unit by pressing the 'Ballot' button on the Control Unit. This allows the voter to cast their vote by pressing the button next to their chosen candidate on the Balloting Unit. A red light on the Balloting Unit flashes, and a beep sound is heard from the Control Unit, confirming that the vote has been recorded. Once voting is complete, the Presiding Officer presses the 'Close' button on the Control Unit to end the polling. The CU then stores the total votes polled for each candidate.
Evolution and Features of EVMs
| Feature | Description |
|---|---|
| Tamper-Proof Design | EVMs are designed with multiple security features, including unique serial numbers, dynamic coding, and a sealed casing, making them difficult to tamper with. |
| No Connectivity | EVMs are standalone devices and are not connected to any network or the internet, preventing remote hacking. |
| Vote Secrecy | Each vote is recorded anonymously, ensuring the secrecy of the ballot. |
| Error Reduction | Eliminates invalid votes that occur due to improper marking on ballot papers. |
| Speedy Counting | Vote counting is significantly faster compared to manual counting of ballot papers. |
| VVPAT Integration | Voter Verifiable Paper Audit Trail (VVPAT) allows voters to verify their vote cast, enhancing transparency and accountability. |
Voter Verifiable Paper Audit Trail (VVPAT)
The VVPAT system is an important addition to EVMs. When a voter presses a button on the Balloting Unit, a paper slip is printed by the VVPAT, showing the serial number, name, and symbol of the candidate they voted for. This slip is visible to the voter for a few seconds before it drops into a sealed compartment. This provides a physical record of the vote cast, which can be used for auditing and verification purposes, thereby increasing voter confidence in the electoral process.
The integration of VVPAT with EVMs is a significant step towards ensuring greater transparency and accountability in elections, allowing for physical verification of votes.
Significance for Competitive Exams (UPSC)
For exams like the UPSC Civil Services Exam, understanding EVMs is crucial for the Polity and Constitution paper. Key areas to focus on include: the constitutional basis for elections, the role of the Election Commission of India (ECI), the legal framework governing elections (e.g., Representation of the People Act), the evolution of voting systems, the technical aspects and security features of EVMs, the importance of VVPAT, and debates surrounding their use. Knowledge of these aspects helps in answering questions related to electoral reforms, election conduct, and the integrity of the democratic process.
