The most important part of an identification card to verify is the picture, notes Drivers License Guide Company. The person's physical attributes, such as facial bone structure, ears and eyebrows, should match the picture on his identification. His height and weight should also match those printed on the ID.
An effective way to verify an ID is to ask the owner basic questions about the information on the card, reports Nightclub & Bar. Confirming the owner's ZIP code, address or zodiac sign can help determine whether or not the ID is legitimate. If the individual has to stop and think about his answer or gives an incorrect answer, the ID may be fake. New smartphone apps are available that automatically scan IDs and determine their legitimacy, according to NBC.
