Is technology used for identifying voters at polling stations (electronic poll books)?

Election Decree (Decree 78 of 1996)

Article 66
Method of Voting

66.1 Every voter desiring to record his vote shall Present himself together with his voting card to the Presiding Officer at the polling Station allotted to him.

66.2 The Presiding Officer, after satisfying himself that the name of a voter is in the copy of the part of the register of voters containing the names of the voters allotted to the polling station, shall subject to subsection (3), deliver a ballot token to the voter.

66.3 The Presiding Officer shall verify in such manner as he considers fit, the authenticity of the voting card presented to him by a voter before he delivers a ballot token to such voter.

Voter identity (ID) cards were used for identification and indelible ink used to mark the forefinger to prevent multiple voting. Polling officials and party agents all had copies of the voter register, which aided the effectiveness and efficiency of the electoral process. The voters register had photos and details of the voters.
