SECURITY PAPER BALLOTS Protecting the security of paper ballots is also a component of providing physical security. Election administrators should have a documented plan in place to provide for the management of optical scan or paper ballots, ballot-on-demand ballots, and all ballot stock. This plan should include details pertaining to the audit trail and chain of custody for the ballots with strict control over the ballots and ballot stock at all time.

 The security of paper ballots includes security in the election office facility and at the polling place on Election Day. At least two election officials should oversee all processes, including the transfer of ballots and other election materials from the polling place to the central office.

 Two or more staff members should receive the ballot order and verify the accuracy and quantity of ballots against the ballot order request. Once validated, the ballots should be stored in a secure building with restricted access in a secure area.

 Ballot-on-demand is often used to supplement printed ballot stock. If used, election officials should implement internal controls to safeguard ballot stock from fraudulent or inappropriate use. For example: • Two or more election officials should monitor, record, and balance daily ballot-on-demand activity. • Election officials should reconcile the number of blank ballots received from the vendor, the number printed or spoiled, and the number of unused ballots.
