Card reader for game machine
First Claim
1. A method of monitoring an amount of money stored in a chip card having a card memory, the chip card being used in conjunction with a games machine, the method comprising:
- providing a chip card reader having a microcontroller;
a program memory for storing a program for operating the games machine;
a re-recordable memory for storing an amount of money available on the chip card;
a random access memory for executing the program;
a card grasping device;
a read/write interface for transferring information between the chip card and said reader; and
an ejection circuit for ejecting the chip card from the chip card reader in response to activation of an ejection button electrically coupled to said ejection circuit;
updating said available amount stored in said re-recordable memory each time a game ends in response to the outcome of the game;
comparing, automatically, said updated available amount with a predetermined minimum amount associated with the games machine;
transmitting the updated available amount to the card memory of said chip card;
generating a rejection signal when said available amount is less than said minimum amount;
disabling the ejection circuit in response to said rejection signal; and
swallowing the chip card in response to said rejection signal.

Abstract
Card reader for game machine with a memory (42) which contains a minimum credit value and receives the credit value available from a card. At each stage of the game, the available credit value varies. The available credit value is compared, on each transaction, with the minimum value. When the available credit value is less than the minimum value, a circuit (47) triggers seizure of the card. A reader of this type can operate by performing all transactions in a memory within the reader, only reading the card memory when the card is inserted into the reader and updating it when the card is ejected.

3. A chip card reader for monitoring an amount of money stored on a chip card, the chip card for use by a player in conjunction with a games machine, the reader comprising:
-
a central processing unit (CPU); a program memory for storing a program for operating the games machine; a re-recordable memory that stores an amount of money available on the chip card, said amount being dependent, upon the outcome of the game; a random access memory for executing the program; a card grasping device that manipulates the position of the card relative to the reader; a controllable motor coupled to said card grasping device for controlling the card grasping device; an ejection circuit electrically coupled to a manually operable ejection button, said ejection circuit for returning the chip card to the player in response to activation of said ejection button; a comparison circuit that automatically compares, at the end of each game and in response to the outcome of the game, said available amount to a predetermined minimum amount associated with the games machine, and generating a control signal when said available amount is less than said predetermined minimum; and a confiscation control circuit that generates a confiscation signal in response to said control signal, and wherein said controllable motor is responsive to said confiscation signal to (1) disable said ejection circuit, and (2) cause said card-grasping device to swallow the chip card when said available amount is less than or equal to said predetermined minimum. - View Dependent Claims (4, 5, 6, 7, 8)
