  • Publication number: 20210005042
    Abstract: A secure ballot collection system is formed of a removable container that may be positioned within a voting machine and used for collecting paper ballots as they are cast. The container itself is capable of being sealed after removal from the voting machine to ensure the security of the paper ballots. The removable container is placed on a raised floor platform that is also positioned within the interior of the voting machine. The platform provides easy access to the interior of the voting machine from a side opening and allows for the ballot container bag to be located at a height where it is relatively straightforward for an election official to place an “empty” container bag at the beginning of the voting process, and also remove a “filled” container bag at some point in time thereafter.
