Optical Scan Voting is a method of casting and counting votes in elections. Voters fill out a paper ballot, marking their choices for candidates or issues. These ballots are then scanned by a machine that reads the marks and tallies the votes electronically. This system combines the reliability of paper ballots with the efficiency of technology. It allows for quick counting and can provide a paper trail for audits, ensuring transparency and accuracy in the electoral process. Many jurisdictions use optical scan systems to enhance the voting experience and maintain election integrity.
