The Registrar of Voters may only use voting technologies approved for use by the California Secretary of State. A list of voting technologies approved for use in California can be found on the Secretary of State’s website, here: https://votingsystems.cdn.sos.ca.gov/cert-and-approval/vote-sys-appr-in-ca-10-30-23.pdf
As with any County department, ROV must follow the County’s procurement rules when purchasing large items or entering into large contracts. The ROV and staff from other County departments evaluate the functionality of each voting system certified by the California Secretary of State.
