Abstract
A method and system for verifying the age of a purchaser prior to his purchase of age-restricted items from a vending machine. An authorization card is issued to a customer containing a password when the customer presents identification material identifying the customer as being of at least a predetermined age. The customer inputs the authorization card into the vending machine, and a comparison of the password on the card is made to the password stored in a microprocessor in the vending machine. If the passwords match, the vending machine is enabled to accept payment from the customer and to vend the age-restricted product.
