How technology is used in relation to paper voter lists?

OSCE/ODIHR Election Expert Team Final Report: Parliamentary Elections, 11 September 2017

“On election day, voters could cast a ballot at any polling station within their municipality, a process simplified in many municipalities by the use of an electronic voter register to identify and to mark voters. […]

While the organization of elections is decentralized, many core functions are universally administered through the EVA, a configuration of several, separate yet integrated systems and modules, which have been enhanced with each successive election since the MLGM began using elements of a common election management system in the 2011 local elections. The EVA is used to facilitate the management of election administration processes, including the registration of candidate lists, the design, printing and scanning of ballots, vote tabulation and the publication of results. It is also key to the functioning of the electronic voter register as a means to identify voters who cast ballots. Municipalities are not legally required to use the EVA. However, its many functionalities, ease of use and availability to municipalities at no cost have led to its universal adoption. Election officials at all levels were highly complimentary of the system, emphasizing that it helped to organize their work, to meet deadlines and to correctly and consistently follow procedures.

Testing of the EVA, including scanning functions, was done twice before election day. Electoral committees and the Directorate were reportedly satisfied with system operations and security. However, shortly before election day, in response to the ongoing public debate over potential external attacks on the EVA, the Directorate issued new IT security recommendations aimed at enhancing the security of counting and tabulation processes. These were only partially implemented by MECs and CoECs due to time constraints”

OSCE EOM Report on 2017 elections states that EVA, which includes electronic voter register in addition to many other functions, was adopted universally across Norway (see the Source).
