Is the biometric data used in voter identification at polling stations?

FAQ section of the CEC website, accessed 25 October 2018

“What is the standard voting procedure?

The elector will have his/her ID card checked by a staff upon arrival at the polling station. Once entering the polling station, the elector should sign/stamp/fingerprint the voter’s list. The elector will then receive the ballots and be able to mark whom he/she wishes to vote using the marking tools prepared by the election commission. The ballot will be placed into the ballot box when the voting action is completed and the elector will proceed to leave the polling station.”
