An ID card is a small, portable document that identifies an individual and verifies their membership, employment, or affiliation with a particular organization. ID cards are commonly used for security and identification purposes, and may include personal information such as the cardholder’s name, photograph, and unique identification number. ID cards may be issued by schools, businesses, government agencies, or other organizations and may be used to access buildings, facilities, or services. They may also be used to verify the identity of the cardholder in various situations, such as when purchasing age-restricted products or accessing restricted areas. ID cards are typically made of plastic and may include security features such as holograms or barcodes to prevent counterfeiting.
