How technology is used in relation to paper voter lists?

Nigeria, INEC, Regulations and Guidelines for the Conduct of Elections, accessed 3 February 2019

10. (a) In accordance with Section 49 (2) of the Electoral Act, a person intending to vote shall be verified to be the same person on the Register of Voters by use of the Smart Card Reader (SCR) in the manner prescribed in these Regulations and Guidelines.

(b) Any poll official who violates the provision of Clause 10 (a) shall be deemed to be guilty of an offence and shall be liable to prosecution. […]

(d) The accreditation process shall comprise reading of the Permanent Voter’s Card (PVC) and authentication of the voter’s fingerprint using the SCR; checking of the Register of Voters and inking of the cuticle of the specified finger of the voter.

Clause 10(b) of the Regulations and Guidelines for the Conduct of Elections provides that any poll officials who violates the Clause 10(a), which obliges identification of voters using Smart Card Reader, shall be deemed to be guilty of an offence. Thus, we assume all the polling stations use technology for voter identification.
