Unlike the other electronic voting systems, programming of ballots is done manually by an election official at a secured location. When voters call from a polling place to connect to the system, the ballot is read to the voters who then make choices using the telephone keypad. The system then prints out a paper ballot at either a central location (central print) or a polling site (fax print). Central print ballots are read back to the voter over the phone for verification, after which the voter can decide to cast the ballot or discard it and revote. Fax print ballots produce a physical ballot at the polling place for the voter to review, verify, and cast in a ballot box. The system also informs voters of undervotes.
