Electronic Voting Machine
The EVMs were devised and designed by Election Commission of India in collaboration with two Public Sector undertakings viz., Bharat Electronics Limited, Bangalore and Electronics Corporation of India Limited, Hyderabad. The EVMs are now manufactured by the above two undertakings.
An Electronic Voting Machine consists of two Units - a Control Unit and a Balloting Unit - joined by a five-meter cable. The Control Unit is with the Presiding Officer or a Polling Officer and the Balloting Unit is placed inside the voting compartment. Instead of issuing a ballot paper, the Polling Officer in-charge of the Control Unit will press the Ballot Button. This will enable the voter to cast his vote by pressing the blue button on the Balloting Unit against the candidate and symbol of his choice.
EVMs can cater to a maximum of 64 candidates. There is provision for 16 candidates in a Balloting Unit. If the total number of candidates exceeds 16, a second Balloting Unit can be linked parallel to the first Balloting Unit. Similarly, if the total number of candidates exceeds 32, a third Balloting Unit can be attached and if the total number of candidates exceeds 48, a fourth Balloting Unit can be attached to cater to a maximum of 64 candidates.
EVMs can record a maximum of 3840 votes. As normally the total number of electors in a polling station will not exceed 1500, the capacity of EVMs is more than sufficient.
An Officer is put on duty to cover about 10 polling stations on the day of poll. He will be carrying spare EVMs and the out-of-order EVM can be replaced with a new one. The votes recorded until the stage when the EVM went out of order will be safe in the memory of the Control Unit and it will be sufficient to proceed with the polling after the EVM went out of order. It is not necessary to start the poll from the beginning.
Advantages of EVMs
• The most important advantage is that the printing of lakhs of ballot papers can be dispensed with, as only one ballot paper is required for fixing on the Balloting Unit at each polling station instead of one ballot paper for each individual elector. This results in huge savings by way of cost of paper, printing, transportation, storage and distribution.
• Secondly, counting is very quick and the result can be declared within 2 to 3 hours as compared to 30-40 hours, on an average, under the conventional system.
• Bogus voting can be greatly reduced by the use of EVMs. In case of ballot paper system, a bogus voter can stuff thousands of bogus ballot papers inside the ballot box. But, an EVM is programmed to record only five votes in a minute. This will frustrate the bogus voters. Further, the maximum number of votes that can be cast in a single EVM is 3840.
• The EVM is compact and comes in its reusable carry pack. Further, the EVM works/operates on a battery power source thus making it independent and totally reliable.
• The Control Unit can store the result in its memory for 10 years and even more. The battery is required only to activate the EVMs at the time of polling and counting. As soon as the polling is over, the battery can be switched off and this will be required to be switched on only at the time of counting. The battery can be removed as soon as the result is taken and can be kept separately. Therefore, there is no question of battery leaking or otherwise damaging EVMs. Even when the battery is removed the memory in the microchip remains intact. If the Court orders a recount, the Control Unit can be reactivated by fixing the battery and it will display the result stored in the memory.
