Description: WIRELESS GAMING ENVIRONMENT BACKGROUND OF THE INVENTION This invention relates to game playing services for gaming machines such as slot machines and video poker machines. More particularly, the present invention relates to methods of providing game services to game players such as ticket validation. There are a wide variety of associated devices that can be connected to a gaming machine such as a slot machine or video poker machine. Some examples of these devices are lights, ticket printers, card readers, speakers, bill validators, ticket readers, coin acceptors, display panels, key pads, coin hoppers and button pads. Many of these devices are built into the gaming machine or components associated with the gaming machine such as a top box which usually sits on top of the gaming machine. Typically, utilizing a master gaming controller, the gaming machine controls various combinations of devices that allow a player to play a game on the gaming machine and also encourage game play on the gaming machine. For example, a game played on a gaming machine usually requires a player to input money or indicia of credit into the gaming machine, indicate a wager amount, and initiate a game play. These steps require the gaming machine to control input devices, including bill validators and coin acceptors, to accept money into the gaming machine and recognize user inputs from devices, including key pads and button pads, to determine the wager amount and initiate game play. After game play has been initiated, the gaming machine determines a game outcome, presents the game outcome to the player and may dispense an award of some type depending on the outcome of the game. As technology in the gaming industry progresses, the traditional method of dispensing coins or tokens as awards for winning game outcomes is being supplemented by ticket dispensers which print ticket vouchers that may be exchanged for cash or accepted as credit of indicia in other gaming machines for additional game play. An award ticket system, which allows award ticket vouchers to be dispensed and utilized by other gaming machines, increases the operational efficiency of mamtaining a gaining machine and simplifies the player pay out process. An example of an award ticket system is the EZ PAY™ ticket system by International Game Technology of Las Negas, Nevada. Currently, ticket vouchers are primarily used as credit indicia for other gaming machines and may be exchanged for cash after the ticket voucher has been validated. However, ticket vouchers have many other potential uses. For example, a ticket voucher may be utilized as prize voucher, which may be redeemed for merchandise awarded for a particular game outcome, or as a service voucher for food, room upgrades or other forms of compensation. An important component of an award ticket system is the ticket validation process. Typically, a game player's satisfaction with an award ticket system is based upon the ease by which the ticket vouchers may be validated or utilized within the context of game playing. When the ticket validation process is difficult, a game player may become dissatisfied with the game playing area offering the award ticket system and frequent a game playing area without an award ticket system or a game playing area offering a simpler ticket validation process. As an example, the ticket voucher validation process is described in relation to the EZ PAY™ system. Figure 1 is a block diagram of the components of the EZ PAY™ ticket system. A first group of gaming machines, 65, 66, 67, 68, and 69 is shown connected to a first clerk validation terminal (CNT) 60 and a second group of gaming machines, 75, 76, 77, 78 and 79 is shown connected to a second CNT 70. All of the gaming machines print ticket vouchers which may be exchanged for cash or accepted as credit of indicia in other gaining machines. When the CNTs are not connected to one another, a ticket voucher printed from one gaming machine may be only be used as indicia of credit in another gaming machine which is in a group of gaming machines connected to the same clerk validation terminal. For example, an award ticket printed from gaining machine 65 might be used as credit of indicia in gaming machines 66, 67, 68 and 69, which are each connected to the CNT 60, but not in gaming machines 75, 76, 77, 78, and 79, which are each connected to the CNT 70. The CNTs, 60 and 70, store ticket voucher information corresponding to the outstanding ticket vouchers that are waiting for redemption. This information is used when the tickets are validated and cashed out. The CNTs 60 and 70 store the information for the ticket vouchers printed by the gaming machines connected to the CVT. For example, CNT 60 stores ticket voucher information for ticket vouchers printed by gaming machines 65, 66, 67, 68, and 69. When a player wishes to cash out a ticket voucher and the CNT are not connected to one another, the player may redeem vouchers printed from a particular gaming machine at the CNT associated with the gaming machine. To cash out the ticket voucher, the ticket voucher is validated by comparing information obtained from the ticket with information stored within the CVT. After a ticket voucher has been cashed out, the CVT marks the ticket paid in a database to prevent a ticket voucher with similar information from being cashed multiple times. Multiple groups of gaming machines connected to CVTs may be connected together in a cross validation network 45. The cross validation network is typically comprised of one or more concentrators 55 which accepts inputs from two or more CVTs and enables communications to and from the two or more CVTs using one communication line. The concentrator is connected to a front end controller 50 which may poll the CVTs for ticket voucher information. The front end controller is connected to an EZ PAY™ server 10 which may provide a variety of information services for the award ticket system including accounting 20 and administration 15. The cross validation network allows ticket vouchers generated by any gaming machine connected to the cross validation to be accepted by other ga ing machines in the cross validation network 45. Additionally, the cross validation network allows a cashier at a cashier station 25, 30, and 35 to validate any ticket voucher generated from a gaming machine within the cross validation network 45. To cash out a ticket voucher, a player may present a ticket voucher at one of the cashier stations 25, 30, and 35. Information obtained from the ticket voucher is used to validate the ticket by comparing information on the ticket with information stored on one of the CVTs connected to the cross validation network. As tickets are validated, this information may be sent to another computer 40 providing audit services. In some instances, to validate and cash an EZ PAY™ ticket voucher, a player must go to the location of the CVT associated with the gaming machines from which the ticket voucher was printed. When the CVTs are connected via a cross validation network, a player must locate a CVT or go to a cashier station at another location. On a large and crowded casino floor, a player may not wish to find the location of a CVT containing the redemption information needed to validate their ticket voucher or may not wish to locate, find and then wait in line at a cashier station to redeem their ticket voucher. Further, when the ticket voucher is for a service such as food or accommodations at a game playing area, a player may wish to take advantage of the service offered on the ticket voucher while continuing their game play or remaining in the game playing area. For example, when the ticket voucher is for a free meal, the player may wish to make a dinner reservation while continuing to play a game on a gaming machine or remaining near the gaming machine. In view of the above, it would be desirable to provide a ticket voucher validation system for gaming machines that generate and accept ticket vouchers which overcome the limitations associated with f ding a location to validate a ticket voucher for a game service. SUMMARY OF THE INVEN ION This invention addresses the needs indicated above by providing a hand-held device having a wire-less communication interface, a display screen and a microprocessor which generates a number of game service interfaces on the display screen.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Turning first to FIGURE 2, a video gaming machine 2 of the present invention is shown. Machine 2 includes a main cabinet 4, which generally surrounds the machine interior (not shown) and is viewable by users. The main cabinet includes a main door 8 on the front of the machine, which opens to provide access to the interior of the machine. Attached to the main door are player-input switches or buttons 32, a coin acceptor 28, and a bill validator 30, a coin tray 38, and a belly glass 40. Viewable through the main door is a video display momtor 34 and an information panel 36. The display monitor 34 will typically be a cathode ray tube, high resolution flat-panel LCD, or other conventional electronically controlled video monitor. The information panel 36 may be a back-lit, silk screened glass panel with lettering to indicate general game information including, for example, the number of coins played. The bill validator 30, player-input switches 32, video display monitor 34, and information panel are devices used to play a game on the game machine 2. The devices are controlled by circuitry (not shown) housed inside the main cabinet 4 of the machine 2. Many possible games, including traditional slot games, video slot games, video poker, and keno, may be provided with gaming machines of this invention. The gaming machine 2 includes a top box 6, which sits on top of the main cabinet 4. The top box 6 houses a number of devices, which may be used to add features to a game being played on the gaming machine 2, including speakers 10, 12, 14, a ticket printer 18 which prints bar-coded tickets 20, a key pad 22 for entering player tracking information, a florescent display 16 for displaying player tracking information, a card reader 24 for entering a magnetic striped card containing player tracking information, and a video display screen 42. Further, the top box 6 may house different or additional devices than shown in the FIGs. 1. For example, the top box may contain a bonus wheel or a back-lit silk screened panel which may be used to add bonus features to the game being played on the gaming machine. During a game, these devices are controlled and powered, in part, by circuitry (not shown) housed within the main cabinet 4 of the machine 2. Understand that gaming machine 2 is but one example from a wide range of gaming machine designs on which the present invention may be implemented. For example, not all suitable gaming machines have top boxes or player tracking features. Further, some gaming machines have two or more game displays - mechanical and/or video. And, some gaming machines are designed for bar tables and have displays that face upwards. Those of skill in the art will understand that the present invention, as described below, can be deployed on most any gaming machine now available or hereafter developed. Returning to the example of Figure 1, when a user wishes to play the gaming machine 2, he or she inserts cash through the coin acceptor 28 or bill vaUdator 30. Additionally, the bill validator may accept a printed ticket voucher which may be accepted by the bill validator 30 as an indicia of credit. At the start of the game, the player may enter playing tracking information using the card reader 24, the keypad 22, and the florescent display 16. Further, other game preferences of the player playing the game may be read from a card inserted into the card reader. During the game, the player views game information using the video display 34. Other game and prize information may also be displayed in the video display screen 42 located in the top box. During the course of a game, a player may be required to make a number of decisions, which affect the outcome of the game. For example, a player may vary his or her wager on a particular game, select a prize for a particular game, or make game decisions which affect the outcome of a particular game. The player may make these choices using the player-input switches 32, the video display screen 34 or using some other device which enables a player to input information into the gaming machine. During certain game events, the gaming machine 2 may display visual and auditory effects that can be perceived by the player. These effects add to the excitement of a game, which makes a player more likely to continue playing. Auditory effects include various sounds that are projected by the speakers 10, 12, 14. Visual effects include flashing lights, strobing lights or other patterns displayed from Ughts on the gaming machine 2 or from lights behind the belly glass 40. After the player has completed a game, the player may receive game tokens from the coin tray 38 or the ticket 20 from the printer 18, which may be used for further games or to redeem a prize. Further, the player may receive a ticket 20 for food, merchandise, or games from the printer 18. In some embodiments, these tickets may be used by a game player to obtain game services. Hardware and methods used to provide various player game services are described with reference to Figs. 3, 4, 5 and 6. FIGURE 3 is a block diagram of a game service system. In one embodiment, the game service system 300 is comprised of a hand-held game service user interface device (GSUJD) 301 and a number of input and output devices. The GSUID 301 is generally comprised of a display screen 302 which may display a number of game service interfaces 306. These game service interfaces 306 are generated on the display screen 302 by a microprocessor of some type (not shown) within the GSUID 301. Examples of a hand-held GSUID which may accommodate the game service interfaces 306 shown in Figure 3 are manufactured by Symbol Technologies, Incorporated of Holtsville, New York. The game service interfaces 306 may be used to provide a variety of game service transactions and gaming operations services. The game service interfaces 306, including a login interface 305, an input/output interface 308, a transaction reconciliation interface 310, a ticket validation interface 315, a prize services interfaces 320, a food services interface 325, an accommodation services interfaces 330 and a gaming operations interfaces 335 may be accessed via a main menu with a number of sub-menus that allow a game service representative to access the different display screens relating to the particular interface. Using the different display screens within a particular interface, the game service representative may perform various operations needed to provide a particular game service. For example, the login interface 305 may allow the game service representative to enter a user identification of some type and verify the user identification with a password. When the display screen 302 is a touch screen, the user may enter the user/operator identification information on a display screen comprising the login interface 305 using the input stylus 303 and/or using the input buttons 304. Using a menu on the display screen of the login interface, the user may select other display screens relating to the login and registration process. For example, another display screen obtained via a menu on a display screen in the login interface may allow the GSUID 301 to scan a finger print of the game service representative for identification purposes or scan the finger print of a game player. The user identification information and user validation information may allow the game service representative to access all or some subset of the available game service interfaces 306 available on the GSUID 301. For example, certain users, after logging into the GSUID 301 (e.g. entering a user identification and a vaUd user identification information), may be able to access the food services interface 325, accommodation services interface 330, or gaming operation services interface 335 and perform a variety of game services enabled by these game service interfaces 306. While other users may be only be able to access the award ticket validation interface 315 and perform EZ PAY™ ticket validations. Using the input/output interface 308, a user of the GSUID 301 may be able to send and receive game service transaction information from a number of input mechanisms and output mechanisms. The input/output interface may allow the GSUID user to select, from a list of devices stored in a memory on the GSUID 301, a device from which the GSUID may input game service transaction information or output game service transaction information. For example, the GSUID 301 may communicate with a ticket reader 345 that reads game service transaction information from bar-coded tickets. The bar-codes may be read using a bar-code reader of some type. The bar-coded tickets may contain bar-code information for awards, prizes, food services, accommodation services and EZ PAY™ tickets. Additionally, the bar-coded tickets may contain additional information including player tracking information that relate the ticket to a specific game player. The information on a ticket is not necessarily in bar-code format and may be in any format readable by a particular ticket reader 345. As another example, the GSUTD 301 may input information from a card reader 340 that reads information from magnetic striped cards or smart cards. The cards may contain player tracking information or other information regarding the game playing habits of the user presenting the card. The GSUTD 301 may output game service transaction information to a number of devices. For example, to print a receipt, the GSUTD 301 may output information to a printer 350. In this game service transaction, the GSUID 301 may send a print request to the printer 350 and receive a print reply from the printer 350. The printer 350 may be a large device at some fixed location or a portable device carried by the game service representative. As another example, the output device may be a card reader 340 that is able to store information on a magnetic card or smart card. Other devices which may accept input or output from the GSUID 301 are personal digital assistants, microphones, keyboard, storage devices, gaming machines and remote transaction servers. The GSUTD 301 may communicate with the various input mechanisms and output mechanisms using both wire and wire-less communication interfaces. For example, the GSUTD 301 may be connected to a ticket reader 345 by a wire connection of some type. However, the GSUTD 301 may communicate with a remote transaction server 360 via a wire-less communication interface including a spread spectrum cellular network communication interface. An example of a spread spectrum cellular network communication interface is Spectrum 24 offered by Symbol Technologies of Holtsville, New York, which operates between about 2.4 and 2.5 GigaHertz. As another example, the GSUID 301 may communicate with the printer 350 via an infra-red wire-less communication interface. The information communicated using the wire-less communication interfaces may be encrypted to provide security for certain game service transactions such as validating a ticket for a cash pay out. Some devices may accommodate multiple communication interfaces. For example, a gaming machine may contain a wire-less communication interface for communication with the GSUTD 301 or a port where a cable from the GSUID 301 may be connected to the gaming machine. Another type of game service interface that may be stored on the GSUID 301 is an award ticket validation interface 315. One embodiment of the award ticket interface 315 may accommodate the EZ PAY ticket voucher system and validate EZ PAY tickets as previously described. However, when other ticket voucher systems are utilized, the award ticket validation interface 315 may be designed to interface with the other ticket voucher systems. Using the award ticket validation interface, a game service representative may read information from a ticket presented to the game service representative by a game player using the ticket reader and then validate and pay out an award indicated on the ticket. Typically, the award ticket contains game service transaction information which may be verified against information stored on a remote transaction server 360. To validate the ticket may require a number of game service transactions. For example, after the obtaining game service transaction information from the award ticket, the GSUTD 301 may send a ticket validation request to the remote transaction server 360 using the spread spectrum communication interface and receive a ticket vaUdation reply from the remote server 360. In particular, the validation reply and the validation request may be for an EZ PAY™ ticket. After the award ticket has been validated, the GSUI 301 may send a confirmation of the transaction to the remote server 360. Details of the game service transaction information validation process are described with reference to Figure 6. In other embodiments, the award ticket interface may be configured to vaUdate award information from a smart card or some other portable information device or validate award information directly from a gaming machine. As game service transactions are completed, game service transaction information may be stored on a storage device 355. The storage device 355 may be a remote storage device or a portable storage device. The storage device 355 may be used as a back-up for auditing purpose when the memory on the GSUID 301 fails and may be removable from the GSUTD 301. Another type of game service interface that may be stored on the GSUID 301 is a prize service interface 320. As an award on a gaming machine, a game player may receive a ticket that is redeemable for merchandise including a bike, a computer or luggage. Using the prize service interface 320, the game service representative may validate the prize service ticket and then check on the availability of certain prizes. For example, when the prize service ticket indicates the game player has won a bicycle, the game service representative may check whether the prize is available in a nearby prize distribution center. The GSUTD 301 may validate the prize ticket and check on the availability of certain prizes by communicating with a remote prize server. Further, the game service representative may have the prize shipped to a game player's home or send a request to have the prize sent to a prize distribution location. The game service transactions needed to validate the prize ticket including a prize vaUdation request and a prize validation reply, check on the availabiUty of prizes and order or ship a prize may be implemented using various display screens located within the prize interface. The different prize screens in the prize service interface may be accessed using a menu located on each screen of the prize service interface. In other embodiments, the prize service interface may be configured to validate prize information from a smart card or some other portable information device or validate award information directly from a gaming machine. A more complete discussion of the use of prize servers is provided in commonly assigned, copending U.S. Patent Application Serial No. 09/515,717 entitled NAME YOUR PRIZE GAME PLAYING METHODOLOGY filed February 29, 2000, the entire specification of which is incorporated herein by reference. Another type of game service interface that may be stored on the GSUTD 301 is a food service interface 325. As an award on a gaming machine or as compensation for a particular amount of game play, a game player may receive a ticket that is redeemable for a food service including a free meal, a free drink or other food prizes. Using the food service interface 325, the game service representative may validate the food service ticket and then check on the availability of certain prizes. For example, when the game player has received an award ticket valid for a free meal, the food service interface may be used to check on the availability of a dinner reservation and make a dinner reservation. As another example, the GSUTD may be used to take a drink order for a player at a gaming machine. The GSUTD 301 may validate the food service ticket and check on the availability of certain food awards by communicating with a remote food server. The game service transactions needed to validate the food ticket, check on the availability of food services, request a food service and receive a reply to the food service request may be implemented using various display screens located within the food service interface. These display screens may be accessed using a menu located on each screen of the food service interface. In other embodiments, the food service interface may be configured to validate food service information from a smart card or some other portable information device. Another type of game service interface that may be stored on the GSUTD 301 is an accommodation service interface 330. As an award on a gaming machine or as compensation for a particular amount of game play, a game player may receive a ticket that is redeemable for a accommodation service including a room upgrade, a free night's stay or other accommodation prize. Using the accommodation service interface 330, the game service representative may validate the accommodation service ticket and then check on the availabiUty of certain accommodation prizes. For example, when the game player has received an award ticket valid for a room upgrade, the accommodation service interface may be used to check on the availabiUty of a room and make a room reservation. As another example, the GSUTD may be used to order a taxi or some other form of transportation for a player at a gaming machine preparing to leave the game playing area. The game playing are may be a casino, a hotel, a restaurant, a bar or a store. The GSUTD 301 may validate the accommodation service ticket and check on the availability of certain accommodation awards by communicating with a remote accommodation server. The game service transactions needed to vaUdate the accommodation ticket, check on the availabiUty of accommodation services, request an accommodation service and receive a reply to the accommodation service request may be implemented using various display screens located within the accommodation service interface. These display screens may be accessed using a menu located on each screen of the accommodation service interface. In other embodiments, the accommodation service interface may be configured to vaUdate accommodation service information from a smart card or some other portable information device. Another type of game service interface that may be stored on the GSUTD 301 is a gaming operations service interface 335. Using the gaming a service interface 335 on the GSUTD 301, a game service representative may perform a number of game service transactions relating to gaming operations. For example, when a game player has spilled a drink in the game playing area, a game service representative may send a request to maintenance to have someone clean up the accident and receive a reply from maintenance regarding their request. The maintenance request and maintenance reply may be sent and received via display screens selected via a menu on the screens of the gaming operations service interface. As another example, when a game service representative observes a damaged gaming machine such as a broken Ught, the game service representative may send a maintenance request for the gaming machine using the GSUTD 301. Another type of game service interface that may be stored on the GSUTD 301 is a transaction reconciliation interface 310. Typically, the GSUTD 301 contains a memory storing game service transaction information. The memory may record the type and time when particular game service transactions are performed. At certain times, the records of the game service transactions stored within the GSUTD 301 may be compared with records stored at an alternate location. For example, for an award ticket validation, each time an award ticket is validated and paid out, a confirmation is sent to a remote server 360. Thus, information regarding the award tickets, which were validated and paid out using the GSUID, should agree with the information regarding transactions by the GSUTD stored in the remote server 360. The transaction reconciUation process involves using the transaction reconciUation interface to compare this information. Another type of game service interface that may be stored on the GSUTD 301 is a voice interface 338. Using the spread spectrum cellular network incorporated into the GSUTD, a game service representative may use the GSUTD 301 as a voice communication device. This voice interface 338 may be used to supplement some of the interfaces previously described. For example, when a game player spills a drink the game service representative may send maintenance request and receive a maintenance reply using the voice interface 338 on the GSUTD 301. As another example, when a game player requests to validate a food service such as free meal, the game service representative may request a reservation at a restaurant using the voice interface 338 on the GSUTD 301. FIGURE 4 is a block diagram of a game service transaction network. In one embodiment, the game service transaction network comprises the EZ PAY™ award ticket system described with reference to FIGURE 1, one or more hand-held game service user interface devices (GSUTDs) as described with reference to FIGURE 3, a printer 425, wire-less communication relays 440 and 435, and wire-less transceivers 400, 410, 420 connected to remote transaction servers 10, 405 and 415. After checking out a GSUTD 430 and logging into the GSUTD 430, a game service representative may roam the game playing area 429 and contact game players in the game playing area 429. The game playing area may be a casino, a hotel, a restaurant, a store or a bar. While playing one or more gaming machines 65, 66, 67, 68, 69, 75, 76, 77, 78 and 79 in the game playing area 429, a game player may receive tickets that require or allow a game service including an award ticket validation, an EZ PAY™ ticket vaUdation, a prize service, a food service, or an accommodation service. The game players may attempt to vaUdate award tickets or EZ PAY™ tickets at the CVTs 60 and 70, at the cashier stations 25, 30 and 35, or by making contact with a game service representative roaming the game player area 429 with a GSUTD 430. For other game services including food services or accommodation services, the game player may have to contact a game service representative with a GSUTD 430. When a game service representative contacts a game player seeking a game service in the game playing area 429, the game service representative uses an appropriate game service interface on the display screen of the GSUTD 430, as described with reference to FIGURE 3, to provide the game service requested by the game player. For example, when a game player requests an EZ PAY™ ticket validation, the game service representative brings the EZ PAY™ ticket validation interface onto the display screen of the GSUTD 430 using menus available on the display screen. Then, the game service representative scans the EZ PAY™ ticket using a ticket reader connected to the GSUTD 430 to obtain unique ticket information. Next, the GSUTD 430 sends an EZ PAY™ ticket validation request using the wire-less communication interface to the EZ PAY™ server 10. Typically, the ticket validation request is composed of one or more information packets compatible with the wire-less communication standard being employed. Using the wireless link 445, the one or more information packets containing the ticket validation request are sent to a transceiver 400 connected to the EZ PAY™ server. The transceiver 400 is designed to receive and send messages from the one or more GSUTDs in the game playing area 429 in a communication format used by the GSUTDs. Depending on the location of the GSUTD 430 in the game playing area, the communication path for the information packets to and from the GSUTD 430 may be through one or more wire-less communication relays including 435 and 440. For example, when the GSUTD 430 is located near gaming machine 77, the communication path for a message from the GSUTD 430 to the EZ PAY™ server 10 may be from the GSUTD 430 to the relay 435, from the relay 435 to the relay 440, from the relay 440 to the transceiver 400 and from the transceiver 400 to the EZ PAY™ server. As the location of the GSUTD 430 changes in the game playing area 429, the communication path between the GSUTD 430 and the EZ PAY™ server 10 may change. After receiving an EZ PAY™ ticket validation reply from the EZ PAY™ server 10, the EZ PAY™ ticket may be validated using an appropriate display screen on the GSUTD 430. After cashing out the ticket, the game service representative may send a confirmation of the transaction to the EZ PAY™ server 10 using the GSUTD 430. The transaction history for the GSUTD 430 may be stored on the GSUTD 430 as well as the EZ PAY™ server 10. Next, a receipt for the transaction may be printed out. The receipt may be generated from a portable printer carried by the game server representative and connected to the GSUTD 430 in some manner or the receipt may be generated from a printer 425 at a fixed location. After providing a number game services comprising a number of game service transactions to different game players in the game playing area 429 using the GSUTD 430, a game service representative may log-off of the GSUTD 430 and return it to location for secure storage. For example, at the end of a shift, the game service representative may check the GSUTD 430 at some the location, the device is unassigned to the particular game service representative and then may be assigned to another game service representative. However, before the GSUTD 430 is assigned to another game service representative, the transaction history stored on the GSUTD 430 maybe reconciled with a separate transaction history stored on a transaction server such as the EZ PAY™ server 10. The assigning and unassigning of the GSUTD to a game service representative and the transaction reconciliation are performed for security and auditing purposes. Another security measure which may be used on a GSUTD 430 is a fixed connection time between the GSUTD 430 and a transaction server. For example, after a GSUTD 430 has been assigned to a game service representative and the game service representative has registered on the GSUTD 430, the GSUTD 430 may establish a connection with one or more transaction servers including the EZ PAY™ server 10, a server 405 or a server 420. The connection between a transaction server and the GSUTD 430 allows the GSUTD 430 to send information to the transaction server and receive information from the transaction server. The length of this connection may be fixed such that after a certain amount of time the connection between the GSUTD 430 and the transaction server is automatically terminated. To reconnect to the transaction server, the login and registration process must be repeated on the GSUTD 430. A transaction server may provide one or more game service transactions. However, the GSUTD 430 may connect with multiple transaction servers to obtain different game service transactions. For example, server 405 may be a prize transaction server allowing prize service transactions and server 415 may be a food transaction server allowing food service transactions. When a game service representative receives a prize service request from a game player, the GSUTD 430 may be used to contact the prize transaction server 405 using a wire-less communication link between the GSUTD 430 and a transceiver 410 connected to the prize transaction server 405. Similarly, when a game service representative receives a food service request from a game player, the GSUTD 430 may be used to contact the food transaction server 415 using a wire-less communication link between the GSUTD 430 and a transceiver 420 connected to the food transaction server 405. The different transaction servers including the servers 10, 405, 415 maybe on separate networks or linked in some manner. For example, server 415 is connected to network 422, server 10 is connected to network 45, and server 405 is connected to network 412. In this embodiment, a network link 414 exists between network 412 and network 45. Thus, server 10 may communicate with server 405 via the network link 414. A communication link between different servers may allow the servers to share game service transaction information and allow different communication paths between the GSUTDs and the transaction servers. FIGURE 5 is a flow chart depicting a method for providing a game service using a hand-held device. In step 500, a game service representative receives a hand-held game service user interface device (GSUTD) and logs in to the device to assign the device. The check out process and assign process are for security and auditing purposes. In step 505, the game service representative contacts a game player in the game playing area requesting a game service of some type. In step 510, the game service representative selects an appropriate interface on the GSUTD using menus on the display screen of the GSUTD that allow the game service representative to provide a requested game service. In step 515, the game service representative inputs game service transaction information required to perform a game service transaction. For example, to validate an award ticket, the game service representative may read information from the ticket using a ticket reader. As another example, to provide a food service including a dinner reservation, the game service representative may enter a game player's name to make the reservation. In step 520, the transaction information obtained in step 515 is vaUdated as required. For example, when a player attempts to cash out an award ticket, the information from the award is validated to ensure the ticket is both genuine (e.g. the ticket may be counterfeit) and has not already been validated. The vaUdation process requires a number of transfers of information packets between the GSUTD and the transaction server. The details of the validation process for an award ticket vaUdation are described with reference to FIGURE 6. When the transaction information is valid, in step 522, a game service transaction is provided. For example, a room reservation may be made for a player requesting an accommodation service. A confirmation of the game service transaction may be sent to the transaction server for transaction reconciliation in step 545. In step 525, a receipt may be generated for the game service transaction. In step 535, after generating a receipt for one service, a game player may request another game service. When a game player request an additional game service, the game service representative returns to step 510 and selects an appropriate interface for the game service. When a game player does not request an additional service and it is not the end of a shift, in step 530, the game service representative returns to step 505 and contacts a new game player. In step 540, when a shift has ended, the game service representative logs out of the GSUTD and checks the device at a secure location so that the GSU D may be assigned to a different game service representative. In step 545, before the GSUTD is assigned to a different game service representative, a transaction history reconciliation is performed to ensure that the transaction history stored on the GSUTD is consistent with the transactions previously confirmed with a transaction server during the game service representative's shift. The transaction history on the GSUTD may be stored on a removable memory storage device on the GSUTD. Thus, the memory may be removed from the device for transaction reconciUation and replaced with a new memory. Thus, the device with the new memory may be assigned to a new game service representative while the transaction history from the previous game service representative assigned to the device is reconciled. FIGURE 6 is a flow chart depicting a method for validating information for providing a personal game service. In the embodiment shown in the figure, a ticket is validated in a manner consistent with an EZ PAY™ ticket system. The EZ PAY™ ticket is usually used for award tickets. However, the system may be adapted to provide tickets for other services include food services, prize services or accommodation services. In step 600, a request for game service transaction information read from a ticket is sent via a wire-less communication interface on the GSUTD to the appropriate transaction server as described with reference to FIGURE 4. In step 605, the server identifies which clerk validation ticket owns the ticket. When a CVT owns a ticket, the CVT has stored information regarding the status of a particular ticket issued from a gaming machine connected to the CVT. In step 610, the server sends a request to pay the ticket to the CVT identified as the owner of the ticket. Typically, the pay request indicates a service on the ticket has been requested. For a cash ticket, a pay request means a request to cash out the ticket has been made. For a free meal, a pay request means a request to obtain the meal has been made. In step 615, the CVT receives the pay request for the ticket and marks the ticket pending. While the ticket is pending, any attempts to vaUdate a ticket with similar information is blocked by the CVT. In step 620, the CVT sends back a reply with context information to the server. As an example, the context information may be the time and place when the ticket was issued. The information from the CVT to the server may be sent as one or more date packets according to a communication standard shared by the CVT and server. In step 625, after receiving the validation reply from the CVT, the server marks the pay request pending and sends a pay order to the GSUTD. While the pay request is pending, the server will not allow another ticket with the same information as the ticket with the pay request pending to be validated. In step 630, the game service representative may chose to accept or reject the pay order from the server. When the game service representative accepts the pay order from the server, in step 640, the GSUTD sends a reply to the transaction server confirming that the transaction has been performed. The transaction server marks the request paid which prevents another ticket with identical information from being validated. In step 645, the server sends a confirmation to the CVT which allows the CVT to mark the request from pending to paid. When the game service representative rejects the pay order from the server, in step 650, the GSUTD sends a reply to the server to mark the pay request from pending to unpaid. When the ticket is marked unpaid, it may be validated by another GSUTD or other vaUdation device. In step 655, the server sends the reply to the CVT to mark the pay request from pending to unpaid which allows the ticket to be vaUdated. Although the foregoing invention has been described in some detail for purposes of clarity of understanding, it will be apparent that certain changes and modifications may be practiced within the scope of the appended claims. For instance, while the gaming machines of this invention have been depicted as having top box mounted on top of the main gaming machine cabinet, the use of gaming devices in accordance with this invention is not so limited. For example, gaming machine may be provided without a top box.
