`ABSTRACT
`Providing change to gaming machine players is facili
`tated by the use of a change card having a memory
`storing a cash value which a change person can use to
`input a credit into a gaming machine in exchange for
`cash from a player. A game monitor unit having a card
`reader, a keypad and a display is attached to the gaming
`machine and can be used to authorize and transfer a
`selected cash value to the credit meter of the gaming
`machine from the change card. Cash values along with
`authorizations and security codes are input to the
`change card at a change station utilizing a similar moni
`tor unit. Financial controls and security can be en
`hanced by transmitting data relating to change card
`transactions from the gaming machine and the change
`station to a central data system.

`GAMING MACHINE CHANGESYSTEM
`
`O
`
`TECHNICAL FIELD
`The invention relates to the field of coin operated
`gaming machines and more particularly to the systems
`for providing change or credit to operate gaming ma
`chines.
`BACKGROUND OF THE INVENTION
`At present there are a number of methods of provid
`ing a player with either credit or coins for playing gam
`ing machines including bill acceptor mechanisms as
`described in U.S. Pat. No. 5,102,136 and by credit card
`readers attached to the machines. However, most gam
`15
`ing machines are not equipped with bill acceptors and in
`many cases players do not possess or want to use a
`credit card with a gaming machine. As a result, many
`casinos employ a number of change persons who circu
`late in the gaming machine area to exchange coins or
`20
`tokens for currency bills. In order to provide change for
`players, the change person must normally carry a large
`number of coins of varying denominations. Very often a
`casino will have gaming machines that accept, for ex
`ample, nickels, quarters, fifty cent pieces or dollar coins
`25
`as well as dollar, five dollar, twenty five dollar or one
`hundred dollar tokens. In addition to the inherent prob
`lems of carrying about a large amount of change on the
`casino floor, this method of supplying players with
`change complicates the casino's accounting procedures
`30
`and increases security concerns. Further, this method
`requires a substantial inventory of coins to be kept on
`hand in the casino to supply the players and the ma
`chines.

`amount of time. The card can also be deactivated by the
`change station or by other components of the system. A
`cancel function can additionally be included to permit
`the change person to use the game monitor unit to trans
`fer a cash value that has been transferred to the gaming
`machine back to the card memory.
`It is a further object of the invention to provide a
`change system having a game monitor unit connected
`to a gaming machine, a change card having a memory
`for storing cash values and a change station which in
`cludes a station monitor unit having a keypad, a display
`and a card reader along with a station computer having
`a keyboard and a computer display where an initial cash
`value is inputted to the card memory by the computer
`keyboard. To enhance security, the station monitor unit
`is not accessible by, nor is it visible to, a cashier operat
`ing the station computer and the station monitor unit
`can be used by a change person to input a confidential
`personal identification number into the card memory.
`The identification number is then used to authorize the
`input of a selected cash value to the gaming machine
`through use of the game monitor unit keypad.
`Another object of the invention is to provide a gam
`ing machine change system where a change card having
`a memory for holding cash values along with an identi
`fication number can be used with a game monitor unit
`connected to a gaming machine that includes a keypad,
`a display and a card reader to input a selected cash
`value to the gaming machine and where an initial cash
`value and the identification number are inputted to the
`card memory by a change station. The system can also
`include a central data system operatively connected to
`both the gaming machine and the change station where
`the initial cash values are recorded in the central data
`system for each card and where the central data system
`is effective to enter a password into the card memory
`that is effective to prevent the game monitor unit from
`accepting a cash value from the card unless the pass
`word is present in the card memory. Additionally the
`central data system can be used to record transactions in
`parallel with the card.
`BRIEF DESCRIPTION OF THE DRAWING
`The drawing is a block diagram of a gaming machine
`change system according to the invention.
`DETAILED DESCRIPTION OF THE
`INVENTION
`The drawing provides an illustration of the preferred
`embodiment of a change system that can be used with a
`variety of different types of gaming machines and
`which eliminates the requirement that change persons
`physically carry coins or tokens. A representative ex
`ample of a gaming machine is shown at 10 which in
`cludes a housing 12, a coin payout tray 14, game control
`buttons 16-20, a control handle 22 and a coin input slot
`24. Also included is a game display 26 which can be a
`set of rotating reels in a slot machine or a video display
`in a video gaming machine. Attached to the housing 10
`is a game monitor unit 28 that includes a twelve charac
`ter dot matrix display 30, a keypad 32 and a combined
`magnetic-smart card reader 34. Also included is a three
`color LED 36 and a sound module 38. A more detailed
`description of a monitor unit that is suitable for use as
`the game monitor unit 28 is provided in co-pending U.S.
`patent application Ser. No. 07/763,924 filed on Sep. 23,

`
`SUMMARY OF THE INVENTION
`It is therefore an object of the invention to provide a
`change system where a change person is provided with
`a change card having a memory for storing an amount
`of money and where each gaming machine is provided
`40
`with a card reader and a keypad so that the change
`person can enter an amount of credit into the machine in
`exchange for cash received from a player.
`It is a further object of the invention to provide a
`change system including a game monitor unit con
`45
`nected to a gaming machine having a card reader, a
`display and a keypad for receiving a change card having
`a memory in which an initial cash value is entered by a
`change station. The keypad can be used by a change
`person to enter a selected cash value into the gaming
`50
`machine by entering a personal identification number
`corresponding to an identification number in the card
`memory and then the selected cash value. In order to
`maintain security of the change card, the change station
`can include a station monitor unit having a keypad, a
`55
`display and a card reader permitting the change person
`to input the identification number into the card mem
`ory. The display can also be used to display the change
`person's name in association with the input of the initial
`cash value.
`It is an additional object of the invention to provide a
`change system having a game monitor unit connected
`to a gaming machine along with a change card having a
`memory containing cash values and a personal identifi
`cation number where a change station can be used to
`65
`input an initial cash value into the card memory along
`with the identification number and where the card is
`automatically deactivated after a predetermined
