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

Cameroon, Electoral Code (2012), accessed 10 February 2020

SECTION 106: (1) The fact that an elector has voted shall be evidenced by affixing the elector’s signature and finger print using indelible ink on the relevant column of the electoral register.

(2) Where the elector is unable to sign, the fact that such elector has voted shall be evidenced by affixing the elector’s finger print using indelible ink on the relevant column of the electoral register.

The manual voting process involves the scrutiny of voters details as contained on the biometric voters card against a physical poll book containing the photo and other registration details of the voter.
