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

Denmark, Folketing (Parliamentary) Elections Act (Consolidated Act No. 1260 of 27 August 2020), accessed 18 March 2023

19.-(3) The local council may decide that an electronic electoral register shall be used for one or more or all polling districts in the municipality.

The use of electronic poll books is not mandatory, and is to be decided by the local municipal council. The council can decide that electronic poll books can be used for one or more or all polling districts in the municipality. If electronic polling books are employed, appropriate fall-back procedures must be in place to ensure that the electronic poll books can be immediately replaced by electoral registers in paper and that the electoral register procedure can be carried out manually if the electronic system should break down or malfunction.
