In the US voting occurs during a workday and so there is a significant push towards 'voting convenience' or 'non-precinct voting' where a voter may appear at any polling place instead of only at their designated precinct. This is a huge advantage for voters but requires that ballots be either selected from a large supply or printed on-site for each voter. This effectively requires the use of a computerized pollbook.
