Title: Apparatus for pre-determined game outcomes

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a Continuation-in-Part of U.S. patent application Ser. No. 10/937,989, titled “APPARATUS FOR PRE-DETERMINED GAME OUTCOMES”, filed Sep. 10, 2004, of which is herein incorporated by reference in its entirety. 
    
    
     TECHNICAL FIELD 
     The present invention relates generally to portable gaming devices and systems, and more specifically to portable memory devices having predetermined game play outcomes for play on gaming devices. 
     BACKGROUND 
     Gaming is an increasingly popular industry, with casinos and other gaming establishments continually seeking new and exciting ways to present games for play. Many games are generally presented on large free-standing gaming devices, such as the well known slot machines, video poker machines and the like. Other games can be presented at something other than a gaming device, such as the table games of craps, blackjack and roulette. In addition, games such as keno and bingo may be played in areas specially configured to present the game to players (e.g., at areas where personnel pick up keno cards and called numbers are displayed on large displays). 
     Such wager-based games allow the casino customers to place bets or wagers that result in winnings if the wager is successful, or losses if the wager is unsuccessful. A substantial disadvantage to the way such games are currently presented is that a player may participate in a particular game only at certain specified locations and/or on specific gaming machines or tables. For example, in order to play video poker or a particular slots game, such as “Red White and Blue,” a player may be required to travel through a large hotel and/or casino to a specific gaming area where an actual video poker or “Red White and Blue” gaming machine is located. 
     Casinos and other gaming operators generally desire to provide to their customers greater accessibility to gaming devices and the opportunity to play games. Of course, added issues can arise whenever players are permitted to engage in gaming events from mobile and/or remote locations, such as through the use of a personal gaming device (PGD). Security for any casino owned PGDs, increased fraud prevention, flexibility in PGD use, and player authentication and verification are only a few examples of such added issues. Furthermore, PGDs are more apt to be stolen, which then allows the thieves to play and collect any winnings from the purchased predetermined games. Additionally, since PGDs are mobile, it is also easier for minors to gain access to play the wager-based games on the PGDs. 
     In light of the foregoing, it is desirable to develop additional methods and systems that provide for improved functionality in mobile gaming involving PGDs, and in particular for such methods and systems to include enhanced security and player authentication features while remaining at similar or better levels of flexibility as on large free-standing gaming devices. 
     SUMMARY 
     The present invention is directed to a gaming apparatus involving pre-purchased predetermined game outcomes stored on a portable memory device, which could be used with either a PGD or a casino gaming system. The portable memory device may have a memory to store at least one predetermined game play outcome for a wager-based game, a processor coupled to the memory, and a biometric sensor. The memory may be used to store at least one predetermined game play outcome for a wager-based game. 
     The portable memory device may be interchangeable with at least one portable gaming device having an interface for receiving and reading the portable memory device, a display, and a controller operatively coupled to the display and the input device. The controller may have a processor having a memory operatively coupled to the processor, the controller being programmed to cause the display to generate a game display relating to the at least one wager-based game, to accept a wager for the at least one wager-based game, and to display the at least one predetermined game play outcome. 
     The portable memory device may also have a biometric sensor to measure at least one biometric data from a user to access the wager-based game. A remote gaming server may be in electronic communication with the PGD and adapted to provide the at least one predetermined game play outcome for the wager-based game to the portable memory device. 
     The present invention also provides for a method for playing the wager-based game on a portable gaming device. A reference biometric data is stored on the PGD, portable memory device, or both. At least one predetermined game play outcome for the wager-based game is stored and encrypted on the memory of the portable memory device. The portable memory device is inserted into the PGD and biometric data is measured from the player on the portable memory device, or alternatively also on the PGD. The measured biometric data is compared to the reference biometric data. If the reference and measured biometric data are the same, the predetermined game play outcome is sent to the PGD for play by the player.

     In general, the present invention is directed to a gaming apparatus involving pre-purchased predetermined game outcomes, which could be used with either an individual gaming unit or a casino gaming system. The PGD or casino gaming system may provide for at least one game of chance requiring that a player place a monetary wager in order to be entitled to play the game, whereupon one or more game outcomes can result in a monetary or other award being granted to the player. 
     The individual gaming unit may be a PGD that is adapted to present a wager-based game for play by a player. An example is described in co-pending patent application Ser. No. 11/155,702, filed Jun. 16, 2005, entitled “Virtual Leash For Personal Gaming Device” and co-pending patent application Ser. No. 10/672,307, filed Sep. 26, 2003, entitled “Personal Gaming Device and Method Of Presenting a Game” which are incorporated herein in their entirety for all purposes.  FIG. 1  illustrates an exemplary PGD, generally numbered  20 , in accordance with one embodiment of the invention. In general, the PGD  20  includes a body or housing  22 . The body  22  may be constructed from a wide variety of materials and in a wide variety of shapes. In one embodiment, the body  22  is constructed from one or more molded polypropylene or other plastic components. The body  22  may be constructed of metal or a wide variety of other materials. As illustrated, the body  22  is generally rectangular in shape, having a front side or face  24 , a rear side or face (not visible), a top end  26 , a bottom end  28 , a first side  30  and a second side  32 . Preferably, the body  22  defines an enclosed interior space (not shown) in which a variety of components are located. 
     In a preferred embodiment, the PGD  20  is adapted to present video and sound game data to a player. As illustrated, the PGD  20  includes a display  34 . The display is located in the front face  24  of the body  22 , thus facing upwardly towards a player. In a preferred embodiment, the display  34  comprises a liquid crystal display (“LCD”), and in particular, an LCD permitting touch-screen input. It will be appreciated that other types of displays may be provided. PGD  20  also includes a sound generating device in the form of at least one speaker  36 . In one embodiment, the speaker  36  is positioned beneath a top or cover portion of the body  22  having one or more perforations or apertures therein through which the sound may readily travel. As illustrated, the speaker  36  is located near the bottom end  28  of the body  22 , generally opposite the display  34 . It will be appreciated that the speaker  36  or additional speakers may be provided in a wide variety of locations, such as at one or both sides  30 ,  32  of the body  22 . 
     In a preferred embodiment, the PGD  20  is adapted to send and/or receive data from another device. As such, the PGD  20  includes one or more data input and/or output devices or interfaces. In one embodiment, the PGD  20  includes an RS- 232  data port  38  for transmitting and accepting data, such as through a cable extending between the PGD  20  and another device, such as a computer. In one embodiment, the PGD  20  includes a USB data port  40  for transmitting and accepting data, also through a cable. In one embodiment, the PGD  20  includes an infrared data transmitter/receiver  42  for transmitting information in wireless, infrared light form. In a preferred embodiment, the PGD  20  includes another wireless communication device  44 , such as a wireless communication device/interface operating at radio frequency, such as in accordance with the IEEE-802.1x or the Bluetooth™ standard. 
     Preferably, a player is permitted to provide input to the PGD  20 , such as for playing a game. As stated above, one means of input may be through the display  34 . The display  34  may also be arranged to accept input via a stylus or other device. In one embodiment, the PGD  20  includes a keypad  46 . In one or more embodiments, the keypad  46  is a sealed keypad having one or more keys or buttons which may be activated by a player, such as by depressing the button with their finger. The PGD  20  can include a microphone  48  arranged to accept voice input from a player. Other input devices may alternatively be provided or be provided in addition to those input devices described. For example, a player may be permitted to provide input through a joystick (not shown). The joystick may comprise a control element associated directly with the body  22  of the PGD  20 . Alternatively, the joystick may be separate from the PGD  20 , and then be placed in communication therewith, such as by plugging in the joystick to a data port of PGD  20 . A smart card reader, optical reader, memory card slot, or other input device may be provided for reading information from another element, such as a card, magnetic stripe, flash memory cards, ticket or the like. PGD may also include a keyboard or mouse. 
     In one embodiment, the PGD  20  includes an image collection device  41 , such as a camera. The image collection device  41  may be used, for example, to capture the image of a user or player of the PGD  20 . This image information may be used for security or authentication purposes, as set forth in greater detail below. The PGD  20  may also include a fingerprint scanner  49 . In one embodiment, as illustrated, the fingerprint scanner  49  may be located behind or beneath a user input button, such as a “spin” or “draw” button. In this manner, a player&#39;s fingerprint may be obtained without the user or player having to consciously participate. As described below, a player&#39;s scanned fingerprint information may be used for authentication purposes. The PGD  20  may include a card reader  50 . As illustrated, the card reader  50  is located in a side  30  of the body  22  of the PGD  20 . In a preferred embodiment, the card reader  50  comprises a magnetic stripe reader for reading information from a magnetic stripe of a card. The card reader may also be adapted to write or store data to a smart card or portable memory module. 
     As illustrated, the card reader  50  includes a slot that is positioned in the side  30  of the PGD  20 . The PGD  20  may be battery-powered, such as with a rechargeable battery pack. An ON/OFF button  47  may be provided for controlling the power to the PGD  20 . The PGD  20  may be docked at or otherwise associated with a free-standing gaming machine or other gaming device. At such times that the PGD  20  is docked, the internal battery of the device can be recharged for later use in an undocked or “remote” mode, as will be readily appreciated. Appropriate detection provisions, warnings and safeguards for a low battery status in PGD  20  while in such a remote mode can also be provided. 
     Preferably, PGD  20  includes control means for controlling the operation of the device, including accepting input and providing output. One embodiment of such a control means is illustrated in  FIG. 2 , a block diagram of an exemplary component arrangement of the PGD illustrated in  FIG. 1 . As illustrated, PGD  20  preferably includes a computing environment serving as the control means. The computing environment includes a central processing unit  52 . The central processing unit  52  preferably comprises a microprocessor. The central processing unit  52  is associated with a bi-directional system bus  54 . The system bus  54  may contain, address lines for addressing a video memory or main memory. In addition, the system bus  54  include a data bus for transferring data between and among components associated with the bus  54 . Alternatively, multiplex data/address lines may be used instead of separate data and address lines. 
     The display  34  is coupled to the bus  54 . In one embodiment, a video memory (not shown) is provided in association with the bus  54 . The video memory may be dual-ported video random access memory. The video memory is preferably coupled to and arranged to drive the LCD display  34 . Of course, the video memory might be coupled to a cathode ray tube (CRT) or other suitable display device. A memory  56  is associated with the system bus  54 . In one embodiment, the memory  56  comprises dynamic random access memory (“DRAM”), synchronous DRAM or other forms of random access memory. The memory  56  may have other forms as well, such as electronically erasable programmable read only memory (“EEPROM”). Preferably, the memory  56  is of the type that permits data to be written thereto and read there from. A mass storage device  58  is preferably also accessible via the bus  54 . The mass storage device  58  may be of the read-only type (such as a CD or DVD optical drive) or may be of the read-and-write variety such as flash memory, compact flash, or CD/DVD-R/W drives. 
     As illustrated, the variety of input and output devices can be associated with the system bus  54 , and thus the other components associated with the bus. As illustrated, the speaker  36 , keypad  46  and card reader  50  are associated with the system bus  54 . A variety of data input/output devices (“I/O Devices”) may also associated with the system bus  54 , such as, though not specifically illustrated, the RS- 232  port  38 , the USB  40 , and the infrared data transmitter/receiver  42 . As will be appreciated, these devices/elements may operate in accordance with different protocols and have different architectures, and have appropriate interfaces provided for communicating with the system bus  54 . For example, the infrared transmitter/receiver may have different layers, including a physical layer including the light-emitting device, and link and other layers which include software and/or hardware, as is known. A variety of other input/output devices may be associated with the PGD  20 , as now known or later developed. 
     As stated above, the PGD  20  may include the wireless communication device  44 . The architectures/protocols of such wireless communication interfaces are well known and thus will not be described in detail herein. In general, however, such an interface  44  permits two-way data communication. The PGD  20  may be permitted to communicate with a wide variety of devices/systems, including at least one device associated with a gaming network. The PGD  20  may send and receive data, including program code, through the wireless communication device  44  (or the other input/output devices, such as the infrared transmitter/receiver). As one example described in more detail below, a gaming server may transmit requested code for an application via a transceiver to the wireless communication device  44  of the PGD  20 . The received code may be executed by the central processing unit  52  as it is received and/or be stored in the memory  56  for later execution. In one embodiment, the PGD  20  may include a mass data storage device (not shown) such as a hard drive, CD-ROM or the like. In one or more embodiments, the memory  56  may comprise a smart card or similar easily removable (and replaceable) device. In such event, data, such as operating code, may be associated with the PGD  20  via a CD-ROM placed in a CD-ROM drive or by insertion of a coded smart card or portable memory device. 
     Although the foregoing exemplary PGD  20  is fairly specific with respect to many details, it will be readily appreciated that a wide variety of similarly suitable devices can also be used as a PGD. As discussed herein, it will be understood that use of the term “PGD” can refer to the exemplary PGD  20  disclosed above, as well as any other suitable device that can serve as a PGD for any purpose of the present invention, and that such a device or devices may or may not be portable or hand-held. Further, while use of the terms “portable” and “mobile” gaming device are used, it is understood that use of other suitable non-portable PGDs may be substituted in relevant instances. 
       FIG. 3  is a schematic of an exemplary gaming system including a PGD in accordance with the invention. As illustrated therein, the gaming system, generally numbered  60 , includes a personal gaming device interface  62 . This PGD interface  62  serves as a gateway to data communications between the PGD  20  and various networks, servers and other devices. In one embodiment, data communications between the PGD  20  and the PGD interface  62  is via a transceiver  64  associated with the PGD interface  62 . In general, the transceiver is arranged to receive information from the PGD interface  62  and transmit it to the PGD  20  and/or receive information from the PGD  20 . As illustrated, a PGD  20  may communicate directly with the transceiver  64 . It will be appreciated, however, that limitations may exist as to the range over which such data can be accurately transmitted. Therefore, in one or more embodiments, one or more relays  66  may be provided for receiving and re-transmitting the data to the appropriate location. 
     As stated above, in a preferred embodiment, the PGD interface  62  serves as a gateway or interface between the one or more PGDs  20  and one or more other devices, systems or networks. The interface  62 , whether in the form of a wireless interface or a docking station, may be associated with or reside in a kiosk, slot or other type of gaming machine, a point of sale device, a personal computer or the like. As illustrated, in one embodiment, the PGD interface  62  is associated with a financial server  68  either via a direct link (as illustrated in  FIG. 3 ) or via a network. The financial server  68  may be a computer or be associated with a computer having a processing unit and one or more data files. The financial server  68  is preferably arranged to confirm financial transaction data. For example, in order for player to be permitted to play a game using the PGD  20 , the player may be required to place a bet. In one embodiment, the portable memory device may be updated using a credit card. In such event, the player may swipe their credit card using the card reader  50  associated with the PGD  20 . This data may be transmitted to the financial server  68  for confirmation (and as is known in the art, generation of financial transaction data, such as a transaction date, time and value). 
     In one embodiment, the system  60  includes a game server  70 . As illustrated, the game server  70  is associated with the PGD interface  62 , either directly or via a network. In one or more embodiments, the game server  70  is, or is associated with, a computing device, such as a processor adapted to execute game code. Preferably, the game server  70  is arranged to provide game data to the PGD  20  via the interface  62 . This game data may comprise video data for generating an image on a display  34  of the PGD  20 , and sound data for generating sound emitted by the speaker  36 . The game server  70  is preferably also adapted to receive input from a player, such as a player selection during the play of a game. In one embodiment, a reservation server  72  is connected to the PGD interface  62 , either directly or via a network. The reservation server  72  may be arranged to accept reservation selections, and provide information regarding available hotel rooms, rates, shows, restaurants and the like for use by a player of the PGD  20  in making a reservation selection. While the PGD  20  may communicate with other devices via direct network links as illustrated in  FIG. 2 , the PGD  20  may communicate with a variety of other devices (via a wired or wireless connection) such as the portable memory device, a printer, kiosk, cell phone, slot machine, another computer, and the like. Internet gateway  74  may also used to allow the PGD  20  to connect to other services available on the Internet. 
       FIG. 4  is a block diagram of the components within an exemplary portable memory device according to one embodiment of the present invention. The portable memory device, generally numbered  400 , is a separate and detachable device from the PGD. The portable memory device  400  may be any memory device such as a memory “stick”, proprietary cartridge, USB drive, player tracking card with a magnetic stripe, smart card, flash memory, recordable integrated circuit, magnetic or optical memory such as a floppy disc or compact disc, specially adapted active RFID unit, or any other memory devices that may remain in the personal possession of the player and may be removably and communicatively coupled to the PGD. 
     As will be described in detail below, a biometric sensor on the portable memory device verifies the player, which allows the player to play the wager-based games on any PGD. This allows a player to play the pre-purchased, predetermined games on any PGD and not be limited to the use of a single, specified PGD. The interchangeability of the portable memory device on any PGD also gives a player the flexibility to play the wager-based games at any time. For example, should the player have to stop a wager-based game in mid-play on a first PGD, the game may be saved on the portable memory device for the player to resume the game at the same stopping point on a different PGD if the first PGD is lost, has no power, or is for some reason unavailable for use. The portable memory device  400  may be used to store pre-purchased, predetermined game play outcomes for a wager-based game. The portable memory device may have a processor  402 , field programmable gate array (FPGA)  426 , a random-access memory (RAM)  404 , and a read only memory (ROM)  410 , each coupled to the processor  402 . The ROM  410  may be used to store the operating system, drivers, authentication codes, certificate identification (which may be obtained from the remote gaming server or certificate authority  412 ), and other software that is to be read by the PGD controller. The computer program instructions and the predetermined game play outcomes stored in the ROM  410  may be encrypted (and decrypted) for security and fraud protection by the cryptography processor  414 . A unique identification chip  416  may be coupled to the processor  402  and used with the ROM  410  to identify the device and user. 
     The predetermined game play outcomes may be obtained from the remote gaming server  412 . The remote gaming server  412  may have a random number generator (RNG) to generate random numbers that correspond to outcomes of a game. The random numbers are then stored on the memory of the portable memory device. By storing the random numbers on the portable memory device, a RNG does not need to be installed on the PGD or portable memory device. This also allows the player to play wager-based games at any location without being in electronic communication with the remote gaming server. Thus, this allows the player to play one or more wager-based games at various locations, on various computing devices, and/or at various times, which may not be conducive to a system that centrally generates game outcomes. Examples of wager-based games are further discussed in detail in co-pending application Ser. Nos. 11/155,702 and 10/672,307 discussed above. 
     Additionally, this prevents the transfer of large portions of game play code to be downloaded onto a PGD or the portable memory device. The portable memory device may contain only the actual game play outcomes, which may also be referred to as “seeds”. Within the context of a command download process, such “seeds” need only be the most basic form of predetermined game outcomes, with nothing more, as opposed to entire video clips of outcomes, game plays and presentations. The seeds are predetermined game play outcomes created at a remote gaming server. When using such basic game seeds, the game play and presentation can be made in a wide variety of ways to arrive at the predetermined game outcome or seed. In other words, each seed need only contain enough information for the PGD to determine the outcome of an actual game play, without telling the PGD how to present that outcome. A given command download of gaming software can provide enough information for a PGD to be able to run its own game presentations that ultimately result in game outcomes reflective of any game seeds that have been downloaded. 
     The portable memory device may be sold as an individual unit and may be updated at any purchase location such as a kiosk, that may or may not be in electronic communication with the remote gaming server, or at any cashier stations such as in the casino, gas stations, grocery stores, malls, and the like. In one arrangement, a casino may allow the player to check out the portable memory device. In another embodiment, the player may be required to leave a deposit to check or rent the portable memory device. The portable memory device may also be purchased for a specific wager amount for a specific number of wager-based games to be played. Thus, the portable memory device is purchased based upon a block of games to be paid for when purchasing or updating the portable memory device. For example, the player may purchase ten wager-based games based at $1.00 per game, for a total of $10.00. The player would not have to confirm payment for each game to be played when it is played, such as by credit card authorization. The player is able to pay for the pre-determined game play outcomes for a block of games at the same time. Once all the games are played, the portable memory device may be removably and communicatively coupled to the purchase locations, such as the kiosk, so that the player may collect any wins from the purchase location. As such, the portable memory device  400  may have an input/output (I/O) interface and may also have a network I/O  422 . The interface  420  may be a USB, disc, or any other interfaces. 
     The biometric sensor  406  may be an additional security/fraud feature to allow the player to access the wager-based game. The biometric sensor may be a fingerprint imager, a retina print imager, a voice pattern imager, a facial component imager, and other similar devices to recognize and identify the player. The biometric sensor offers a reliable and inexpensive way to authenticate the identity of a player, which is more secure than personal identification numbers (PINs) or passwords, which are subject to being compromised or forgotten. Examples of portable memory devices may be the Micro Vault by Sony or the JumpDrive TouchGuard by Lexar. 
     Briefly, in one example utilizing the fingerprint imager, one or more fingers of the player must first be registered to obtain a reference biometric data. As the player places their fingertip on the fingerprint sensor, it detects and captures the small variations in finger surface-capacitance and creates a three-dimensional electrical image of the fingerprint&#39;s unique capillary pattern. These signals are verified and then stored into the memory of the portable memory device or PGD. The portably memory device or PGD is “locked” and subsequent placement of any finger on the sensor triggers a verification process, as discussed below. This involves comparing the reference biometric data with the measured biometric data. 
     A greater description of a finger print reader as an identification device is provided in U.S. Pat. No. 6,488,585, issued Dec. 3, 2002, to Wells, et al., entitled “Gaming Device Identification Method and Apparatus,” which is incorporated by reference herein in its entirety and for all purposes. Other types of verification methods such as a PIN or a password may be used separately or in combination with biometric identification methods. 
     The reference biometric data may be stored on the memory of the portable memory device or on the PGD and may be encrypted for additional security. When obtaining either the portable memory device or PGD (i.e. upon sale, rental, etc. of the devices), the player must provide the reference biometric data at that time. The reference biometric data may be obtained by a separate sensor and alternatively stored in a central biometric database. Should the player want to purchase, rent, etc. additional portable memory devices or PGDs, the player needs to only register his fingerprint once. For example, the player may register his fingerprint with the casino, which may be saved and stored in a database of a remote gaming server. The reference biometric data may then be downloaded to the memory of the PGD or portable memory device. Should the player want to purchase, rent, etc. a second PGD or portable memory device, the casino may merely reuse the same reference biometric data for downloading onto the second PGD or portable memory device. 
     Alternatively, the reference biometric data may be stored on the ROM  410  of the portable memory device  400  or on the PGD prior to the first use of the device. If the reference biometric data is stored on the portable memory device  400 , the portable memory device  400  may verify the data by comparing the measured biometric data with the reference biometric data. If the measured biometric data does not match the reference biometric data, the predetermined game play outcome is not decrypted or sent to the PGD controller for operation of the wager-based game. It is beneficial for the reference biometric data to be stored on the portable memory device since the player will be able to use the device on any PGD and/or at any stationary free standing gaming machine. On the other hand, if the reference biometric data is stored on the PGD, the player is limited to the use of that specific PGD. 
     However, it is possible for the reference biometric data to also be stored on the PGD as either a primary or secondary verification check. The reference biometric data ideally would be obtained and stored in the memory before the play of games on the PGD. In a primary verification process, the PGD controller would obtain the measured biometric data from the memory of the portable memory device and compare it to the reference biometric data stored in the PGD memory. Alternatively, the measured biometric data may be obtained from a biometric sensor on the PGD itself. If the measured biometric data does not match the reference biometric data, the PGD would not operate and/or allow the player to play the wager-based game. The PGD may also act as a secondary verification check. In addition to the verification done by the portable memory device, the PGD may also verify that the measured biometric data is matched to the reference biometric data. This would increase the security of the portable memory device and PGD. 
     Should the biometric data not match, the player would be informed during the verification process. The player may be informed, for example, with an audible alarm and/or message on the PGD. The player may also be advised to contact a casino representative to determine the origin of the data discrepancy. 
     There may be various ways in which game play discrepancies may be resolved. Where a player buys, for example, a block of 10 game seeds or game outcomes, these outcomes can preferably be saved at the remote gaming server before being transferred to the portable memory device. Should the player then claim a loss of power, battery failure, or other malfunction, the same exact 10 video clips or games seeds could be downloaded again at a later time, due to the recorded version being stored on the remote gaming server  412 . The portable memory device  400  may also have a flash memory  424  store the game state, game history, license data, expiration dates, or any other information. In a preferred embodiment, the official version of any downloaded game outcome is the version that is stored at the remote gaming server  412 , for both verification and security purposes. Thus, where a player presents a portable memory device that displays a final overall amount or game play balance that does not reconcile with the amount stored on the remote gaming server, the amount stored on the remote gaming server  412  can be the amount to be officially recognized. Disputes over differing amounts could be handled in a manner similar to other gaming machine or casino malfunctions or discrepancies. 
     Although not necessary, the POD and portable memory device may each have a transmitter/receiver or transceiver  418  to transmit and receive information from the remote gaming server. This would allow the player to buy additional blocks of game play without having to return to the purchase location. Additional purchases may be made with a credit card transaction, use of existing wins, or the like either through the use of the portable memory device or the POD. 
       FIG. 5  is a flow chart illustrating an exemplary method for playing a wager-based game on a portable gaming device according to one embodiment of the present invention. The player may enter a purchase location at  500 , such as a kiosk, cashier station, gas station, grocery store, mall, and the like. The player may then chose a purchase option at  502 . The options may be to purchase a portable memory device, purchase additional predetermined game plays, collect winnings, etc. The portable memory device is inserted into a receiving device at the purchase location at  504 . The receiving device may be any device that is able to read from and write to the portable memory device. 
     The identity of the player may be verified prior to inserting the portable memory device into the receiving device if the referenced biometric data is stored on the portable memory device. However, if the identity of the player is not verified at  506 , the reference biometric data may be obtained from alternative sources at  508 . For example, the reference biometric data may be obtained from a player tracking card that the player must swipe through the receiving device. In another embodiment, the reference biometric data may be obtained from a central biometric database at the casino. 
     Once the identity of the player is verified at  510 , the player may pay for the purchase at  512 . Alternatively, the player may also receive the winning from previous predetermined game play outcome games. The method of payment may be through the use of a bill validator, a cashless ticket, credit card, debit card, or any other similar methods of payment. Once paid for, the system may generate the predetermined game play outcomes at  514  and store them on the portable memory device at  516 . The system may be the receiving device, a remote gaming server, a slot machine, or any other system that is able to generate the predetermined game play outcomes. The portable memory device may then be removed from the receiving device at  518  for play on a PGD. 
       FIG. 6  is a flow chart illustrating another exemplary method for playing a wager-based game on a portable gaming device according to another embodiment of the present invention. A reference biometric data of a player may be obtained and stored in a memory at  600 . The biometric sensor may be an additional security/fraud feature to allow the player to access the wager-based game and the reference biometric data may also be encrypted. The biometric sensor may be a fingerprint imager, a retina print imager, a voice pattern imager, a facial component imager, and other similar devices to recognize and identify the player. The biometric sensor offers a reliable and inexpensive way to authenticate the identity of a player, which is more secure than personal identification numbers (PINs) or passwords, which are subject to being compromised or forgotten. 
     The reference biometric data may be stored on the memory of the portable memory device or on the PGD. When obtaining either the portable memory device or PGD (i.e. upon sale, rental, etc. of the devices), the player must provide the reference biometric data at that time. The reference biometric data may be obtained by a separate sensor and also stored in a central biometric database. Should the player want to purchase, rent, etc. additional portable memory devices or PGDs, the player needs to only register his fingerprint once. For example, the player may register his fingerprint with the casino, which may be saved and stored in a database on the remote gaming server. The reference biometric data may then be downloaded to the memory of the PGD or portable memory device. Should the player want to purchase, rent, etc. a second PGD or portable memory device, the casino may merely reuse the same reference biometric data for downloading onto the second PGD or portable memory device. 
     Alternatively, the reference biometric data may be stored on the memory of the portable memory device or on the PGD prior to first use of the device. If the reference biometric data is stored on the portable memory device, the data may be verified by the portable memory device processor by comparing the measured biometric data with the reference biometric data, both stored on the memory of the portable memory device. If the measured biometric data does not match the reference biometric data, the predetermined game play outcome is not decrypted or sent to the PGD controller for operation of the wager-based game. It is beneficial for the reference biometric data to be stored on the portable memory device since the player will be able to use the device on any PGD and/or at any stationary free standing gaming machine. On the other hand, if the reference biometric data is stored on the PGD, the player is limited to the use of that specific PGD. 
     However, it is possible for the reference biometric data to also be stored on the PGD as either a primary or secondary verification check. The reference biometric data ideally would be obtained and stored in the memory before the play of games on the PGD. In a primary verification process, the PGD controller would obtain the measured biometric data from the memory of the portable memory device and compare it to the reference biometric data stored in the PGD memory. Alternatively, the measured biometric data may be obtained from a biometric sensor on the PGD itself. If the measured biometric data does not match the reference biometric data, the PGD would not operate and/or allow the player to play the wager-based game. The PGD may also act as a secondary verification check. In addition to the verification done by the portable memory device, the PGD may also verify that the measured biometric data is matched to the reference biometric data. This would increase the security of the portable memory device and PGD. 
     At least one predetermined game play outcome for the wager-based game may be stored on a memory of a portable memory device at  602 . The memory may be coupled to a portable memory device processor to encrypt the predetermined game play outcome at  604 . 
     The portable memory device may then be inserted into the PGD at  606 . Biometric data from the player may be measured at  608 . The biometric data may be measured on the portable memory device and/or PGD and stored on the memory of the portable memory device and/or PGD. The measured biometric data may then be compared to the reference biometric data at  610 . Those of ordinary skill will now realize that the steps may be performed in various orders. For example, the comparison may occur prior to the device being inserted into the PGD. As stated above, the reference biometric data may either be stored and/or retrieved from the portable memory device or on the PGD. If the measured biometric data does not match the reference biometric data at  612 , the predetermined game play outcome is not decrypted or sent to the PGD controller for operation of the wager-based game. Additionally, the PGD would not operate and/or allow the player to play the wager-based game. However, if the reference and measured biometric data match at  612 , the predetermined game play outcome is sent to the PGD controller at  614  for display on the PGD. 
     The portability of the portable memory device allows a player to play the pre-purchased predetermined games on any PGD and not be limited to the use of a single, specified PGD. The interchangeability of the portable memory device on any PGD also gives a player the flexibility to play the wager-based games at any time. For example, should the player have to stop playing a wager-based game on a first PGD in the middle of the game, the game may be saved on the portable memory device for the player to resume game play on a different PGD if the first PGD is lost, has no power, or is for some reason unavailable for use.
