Make sure you are aware of your polling booth. You can check this on the Election Commission website by entering the 10 digit unique number on your Voter ID card
After reaching the booth, a government official will verify your name in the list and request your ID proof.
An indigo coloured ink would be marked on your index finger indicating that you have taken part in the voting process. You will also receive an acknowledgement slip.
After showing your slip and inked finger, you will be allowed to enter the booth. Now, you can vote for the candidate that you deem fit, and a beep sound from the EVM will confirm your vote.
A slip will appear on the VVPAT machine highlighting the choice you have made.
