PROBLEM TO BE SOLVED: To provide a prize exchange system capable of exchanging prize balls to an optional matter desired by a game player. SOLUTION: A card conversion device 200 transmits the number of prize balls acquired by the player in a game parlor 10, the card number of an inserted financial card 182 such as debit card or the like, and the identification code of the game parlor to the payment management device 31 of a second management institute 30. The payment management device 31 registers the number of prize balls by card number any by identification code. When the payment of spent money in shopping or the like is performed through a payment terminal 41 by use of the financial card 182, the payment management device 31 performs the payment processing of the spent money by use of one or both of the fund obtained by converting the number of prize balls registered by game parlor in conformation to the card number into money according to a prescribed priority order and the balance of an account. Accordingly, the player can use the prize balls acquired in two or more game parlors for payment of shopping in a general store. |
