How technology is used in relation to paper voter lists?

EU Election Observation Mission: Uganda, Presidential, Parliamentary and Local Council Elections [Final Report], accessed 4 November 2018

“EU EOM observers reported that voters were frustrated by the slow pace of voting, caused by the newly introduced biometric voter verification device. It was, however, functional and operated adequately by polling staff despite limited training, and was consistently used in about 95 per cent of polling stations observed. However, the voter register was not used consistently as a primary means of voter identification in several polling stations visited.”

EOM report mentions that the verification devices have been used consistently in about 95% of polling stations observed.
