The Ballot Unit (BU)
Voting using EVM
The EVM does not change the existing voting pattern but only replaces the issuing of a paper ballot by the press of a green button on the Control Unit and instead of the voter marking or making a cross on the ballot paper, he/she will be pressing a green button corresponding to the political party or candidate of his or her choice. The voter then has to press the red Register button on the Ballot Unit to complete the voting process.
The other processes in the polling station such as Verification of Voter Identity against the voter register, checking if a voter has voted before under the Ultra Violet Light and the Inking process are retained.
