A badge is a small piece of metal, plastic, or cloth with a design or symbol on it. It is usually worn on clothing to show that the person wearing it belongs to a particular group or organization. Badges are commonly used by police, military, and emergency services to identify themselves, but they can also be used for events, clubs, and other groups. If someone says they have a badge, it means they have a form of identification that shows their membership in a certain group or organization.
