Authorization verification systems and methods are described that determine whether an authorization check is to be performed at a point of sale or other point of control, and, if the authorization check is to be performed, that check the authorization and that store a retrievable record of the authorization check. The system receives authorization information for an individual that is indicative of the individual's authorization to purchase a product or service, to enter a location, to attend an event, or to otherwise participate in an encounter whose access is limited to authorized individuals. In one embodiment, authorization for making a purchase is limited to individuals above an age threshold, and the authorization verification system receives information relating to the individual's age via an electronic scanning of a driver's license or other identification card, or by other methods, and uses the birth date information to calculate the customer's current age. The current age can be displayed on an existing display of a point-of-sale device or other display. A record of the authorization can be stored and can subsequently be retrieved to verify that an authorization check for the encounter was carried out.
