An ID holder is a practical accessory designed to securely display identification cards, such as driver's licenses, employee badges, or student IDs. Typically made from materials like plastic or leather, these holders often come with a slot or a clip for easy attachment to clothing, bags, or lanyards. ID holders help protect cards from wear and tear while ensuring they are visible for quick access. They are commonly used in various settings, including workplaces, schools, and events, making it easier for individuals to present their identification when required.
