This newspaper story describes the advantages of electronic poll books and scanners at the polling place. Sioux Falls, South Dakota’s School District will soon hold an election in which a voter within the district can vote at any of the ten voting locations, rather than just one particular location. Officials at that voting location scan the voter’s driver’s license or state ID card. Also, the voter signs in with an electronic signature. This system prevents anyone from voting with the same ID card more than once.
