PROBLEM TO BE SOLVED: To improve the convenience of customer by providing a prepaid card effective only in the card publishing shop for a predetermined period after the publication and enabling the prepaid card for the remainder to be type recorded as an update card and used even in the other shop. SOLUTION: Each game parlor is provided with a terminal controller 10 connected to a plurality of islands. Each island is constituted from a plurality of game units controlled by an island controller 40, a sailing machine for sailing prepaid cards and a card machine 30. The update machine 30 collates the data of card including an ID number with the prepaid card purchased in the other shop and inserted when the predetermined term of validity (for example 8 days) passes after the first card publishing day and within one month after the card publishing day. When the result of the collation is OK, an update card setting the remainder to the beginning amount of prepaid money is published (then, a new term of validity for 8 days is recorded). |
