摘要：In this method, the chip cards are numbered and there is a central computer which, when the card is issued, stores at least the amount paid in for gambling under the number of the chip card, and each automatic gambling machine contains a reading/writing device which, before the game is enabled, compares the available amount with the credit which is stored under the corresponding card number in the central computer and only enables the game when these match, and continuously transmits existing credit balances to the central computer.
