If the voting system is not connected to the internet, why did I receive a message from BallotTrax when I voted at my polling place notifying me that my ballot “was received and counted” before I left the polling place?

Voters receive the status of their ballot by signing up for BallotTrax on the Secretary of State’s website. When voters vote at polling places, they check-in using an electronic roster, which sends a message to BallotTrax, and BallotTrax sends the voter a standardized status message that San Bernardino County cannot change.
