An Electronic Voting Machine (EVM) is an electronic device used for recording votes. EVMs came as a replacement to ballot papers and was first used in No. 70 Parvur assembly constituency in Kerala in 1982.
An EVM comprises of a control unit which is placed with the polling officer and a balloting unit which is placed inside the voting compartment.The role of the polling officer is to release a ballot by pressing the ballot button on the control unit. This will allow the voter to cast his vote by pressing the blue button on the balloting unit against the candidate and symbol of the voter's choice. Since 2001, the issue of unreliability of EVM's has been raised many times but the election commission has ruled out any scope for manipulation of votes through EVM's.
EVM's run on normal battery and they do not require electricity. An EVM can be used to record a maximum of 2,000 votes. If an EVM stops working it is replaced with a new one and votes recorded until that time are safe in the memory of the control unit. The control unit can store the result in its memory until the data is deleted or cleared. Changing of the paper roll is strictly prohibited at polling stations.
