It's not an automated system. It's not a system that sends someone a PIN and they then use their touch-tone phone to vote. It's operator-assisted. The voter is registered previously. The voter has to call in. They have to authenticate themselves based on information that only they know and we know about their voter record. They are then passed on anonymously at that point to the team that administers the vote. There are two people. One of them records the vote and the other person verifies the vote back to the individual over the phone. In that way the secrecy of that ballot is maintained.
The other thing about voting by mail and other absentee ballots, for which assisted telephone voting is an option, is that they don't go directly into a ballot box to be counted on election night. Rather, they are enclosed in the envelopes—the secrecy envelope and the certification envelope—and they then go through an intensive screening process following election day to make sure that they can be counted at the final count. That includes making sure they are properly registered and that they didn't vote more than once.
