Abstract
In a vending machine for which both money and a prepaid card can be used, a writing-instruction switch is provided for controlling of amount information into the card. When the writing-instruction switch has been actuated, the amount of inserted money and the credited value of the card are added up and the sum is written into the card for renewing its credited value. In this manner, it becomes possible to additionally renew the amount recorded in the prepaid card. Further, an amount selector may be provided for selecting an amount to be added to a prepaid card. On condition that money of an amount not smaller than the amount selected by the amount selector has been inserted, the selected amount and the recorded amount of the card are added up for renewing the recorded amount of the card. Thus, it becomes possible to write a desired amount into an already issued prepaid card.
