Requires voting machines to be recertified annually and after software modifications.

S 2600 requires New Jersey's Secretary of State to annually re-examine and recertify all voting machines used in the state, and to conduct a new recertification whenever software modifications are made to the machines. This directly affects all local election officials and voting machine vendors operating in New Jersey by mandating regular verification before each election. The bill specifies that the Secretary must develop pre-election tests and checklists to confirm machines accurately record and tabulate votes. These requirements aim to ensure ongoing reliability of voting technology without altering election procedures. The bill does not change existing approval processes for new machines but adds mandatory ongoing checks.
