Identity documents are official papers that verify a person's identity. Common examples include passports, driver's licenses, and national ID cards. These documents typically contain personal information such as the individual's name, date of birth, and a photograph. They are essential for various activities, including travel, banking, and accessing government services. Identity documents help prevent fraud and ensure security by confirming that a person is who they claim to be. Many countries have specific requirements for obtaining these documents, which may involve providing proof of citizenship or residency, as well as undergoing background checks.
