Voter registration systems are processes that allow eligible citizens to sign up to vote in elections. These systems collect personal information, such as name, address, and date of birth, to verify a person's identity and eligibility. Each state in the United States has its own rules and methods for registration, which can include online applications, mail-in forms, or in-person registration at designated locations. Once registered, voters are added to a database that helps election officials manage the electoral process. This system ensures that only eligible individuals can cast their votes, maintaining the integrity of elections. Voter registration is crucial for participation in the democratic process.
