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

Electoral Law (1980, last amended in 2013)

Method of voting

38. The voting at an election shall be conducted in the following manner—

(a) every elector desiring to record his vote shall present himself to a polling assistant at the polling station at which he is entitled to vote, and the polling assistant, after satisfying himself that the name of such elector appears on the copy of the register of electors, or part thereof provided for that polling station, and that he has not already voted, shall deliver to him a ballot paper, in the form prescribes in the Fourth Schedule; [Act 4/05]

EMB website as well as ​Electoral Law (Article 38) provides information on how to vote. From the given information it can be assumed that biometric data are not used for identification at polling stations.
