An Identification Document is an official paper or card that verifies a person's identity. Common examples include a driver's license, passport, or national ID card. These documents typically contain personal information such as the individual's name, date of birth, and a photograph, making it easier to confirm their identity in various situations. Identification documents are essential for many activities, including traveling, opening bank accounts, and applying for jobs. They help ensure security and prevent fraud by providing a reliable way to prove who someone is. In many countries, having a valid identification document is a legal requirement.
