Abstract

An automatic vending machine is disclosed that operates in response to a card inserted by a user. The card contains identification information which is used to access data stored in a memory device regarding the amount of money the user has credited to his account. If the account balance exceeds the purchase price of a desired item, the item is supplied to the user and the amount of the purchase is deducted from his account. A user may increase his account balance at any time by inserting money into the machine. Security is maintained through the use of a security code which the user inputs into the machine after the card is inserted.
