PURPOSE:To omit the storage of a key number and to prevent the key number from using by stealth by collating the key number on the basis of user's personal voice. CONSTITUTION:When a card 1 is inserted into a vending machine 2, the vending machine 2 is connected to the center 3 of a selling company. If voice information pronounced from the user is sent to the center 3, the center 3 confirms the person carrying the card 1 with the owner of the card 1, and after the confirmation sends a selling OK signal to the vending machine 2. The vending machine 2 delivers goods in accordance with user's specification on the basis of the OK signal and the center 3 claims the corresponding amount to the bank. |
