Authorization verification systems and methods are described that store a record of an authorization determination performed at a point of sale or other point of control. The system receives authorization information for an individual 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, 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 as part of a transaction record that can subsequently be retrieved to verify that an authorization determination for the encounter was carried out.
