SOLUTION: In a pachinko hall, a card stored with an identification number is issued from a card issuing machine 1, and the card is charged in a card type ball vending machine 2 of a desired pachinko machine, which is a ball dispenser, and the information of the card in use is stored in both the card type ball vending machine 2 and a control server computer 5 online-connected to the card type ball vending machine 2. Information on an amount of money is not written in the card, but card information is normally controlled by the server computer 5. In the case of on-line being cut off, communication is maintained among the card issuing machine 1, a settlement machine 4 and the card sound to dispense the balls and to make the settlement. |
