A card issuer first visually confirms that a person who requests the issue of a user card is an adult. The card issuer then issues a user card on which data unique to the card has been previously recorded. The person writes his (her) name, address and the like on the card. The card is then inserted into a card reading section. An apparatus for identifying minors performs certain processing of the data unique to the card read in the card reading section to output an identification number unique to the card, which is displayed on a number display. The user memorizes this identification number as a code number. In buying a product, the user inserts the issued card into the card reading section and, in addition, inputs the code number through a ten key. When the identification number of the card is identical to the input code number, the apparatus for identifying minors outputs a sale permission signal. By virtue of this constitution, the user authentication system makes it difficult to transfer an authentication card to others and, at the same time, can identify minors in a vending machine for alcoholic beverages while ensuring the security through a code number.
