Field of he Invention 00 This invention relates generally to the field of pay computer-controlled games, (c either games of skills or games of chance, and more particularly to the field of cashless o gaming systems and methods.
0 2. Description of the Related Art Conventional cashless methods and systems typically rely on centralized accounts (player accounts, anonymous game session accounts, voucher verification accounts, smartcard reconciliation accounts) that are managed by a complex central system controlled or coupled to a central server). Such systems require the services of highly trained professionals and the maintenance of stringent security procedures. This leads to high operational costs that are not acceptable for small to medium sized gaming operators.
Centralized systems of the prior art are described in US6,280,328, US5,265,874 and US6,048,269.
What are needed, therefore, are cashless gaming methods and systems that overcome the complexity, cost and manpower of conventional gaming methods and systems.
SUMMARY OF THE INVENTION The present invention, therefore, seeks to offer gaming terminals and network architectures, systems and methods that overcome the complexity, cost and manpower inherent in conventional gaming terminals, network architectures, methodologies and systems.
According to embodiments of the present invention, each networked gaming terminal comprises a highly secure enclosure because of the strict regulations that are imposed in gaming jurisdictions. The compute modules thereof are carefully partitioned with multiple locking mechanisms and alarm systems. Strict procedures must be followed to access various parts and functions. Furthermore, the computer architecture COMS ID No: SBMI-07116918 Received by IP Australia: Time 15:25 Date 2007-04-24 24-04-'07 15:09 FROM-DCC SYDNEY +61292621080 T-742 P007/035 F-732 0 ci and components of motherboards used in gaming machines are becoming enormously powerful and extrenmely reliable due to the technology advancements; they are identical to those used in computer servers that constitute complex central systems. Therefore, networked gaming terminals may offer an exceptionally secure and exceedingly powerful O computing environment.
00 00 In the present invention, the gaming terminals are advantageously configured to Ssupport functions traditionally implemented by centralized systems. Gaming terminal Ssoftware is adapted to support, in addition to the local terminal game session metering o (including, for example, tracking of winning and available credits), the game session 'r 10 metering of one or a plurality of peer gaming terminals. A patron may deposit funds in cash or using any other financial instrument (including, for example, any form of electronic money) to a cashier or an automated network cashier, or alternatively a gaming terminal equipped with cash acceptors or other financial instrument acceptors.
According to an embodiment of the present invention, the amount of money deposited by is the patron is credited by the cashier, or gaming terminal or using a basic stateless not managing the session context) entry terminal, into a peer gaming terminal or alternatively, the equivalent operation may be automatically performed by the automated network cashier: In the case of a gaming terminal equipped with financial instrument acceptors, the credit is entered directly into the local meters not stored in memory prior to being transferred to the local meters of the gaming tnnrminal). The patron may be issued an identification (ID) instrument that may be accepted by any gaming terminal in the network. Each time the patron submits his ID instrument (or is otherwise authenticated) to a new gaming terminal on the network, the new gaming terminal may broadcast a network message to request the previously used gaming terminal to transfer to the new terminal the game session meters corresponding to the ID instrument. That is, the request may be broadcast to all gaming terminals on the network and only the gaming terminal owning the requested game session meters will respond to the broadcast request.
Consequently, the patron may play on any gaming terminal within the network and change gaming tenuinal at any time as long as his game session credit is not exhausted.
so The transfer of meters preferably occurs directly between the networked gaming terminals, without the intermediary of an intervening terminal or storage.
The patron may redeem his winnings or remaining credits by submitting his ID COMS ID No: SBMI-07116918 Received by IP Australia: Time 15:25 Date 2007-04-24 24-04-'07 15:09 FROM-DCC SYDNEY +61292621080 T-742 P08/35 F-32 0 o3 instrument to an automated cashier, to a cashier equipped with a network entry terminal c- or to a gaming terminal equipped with a coin dispenser or a bank note dispenser. For the payment operation, payment authorization may be obtained via the network from the last gaming terminal on which the patron last played.
Ss For fault tolerance, each game session meter may be mirrored on one or a plurality of peer gaming terminals on the network.
It is a further object of this invention supports all forms of cashless instruments such as: O a player account whereby primary meters are the monetary credit balance 1o associated to a patron.ID; San anonymous game session account whereby primary meters are the monetary credit balance associated to a game session ID; a voucher verification account whereby the primary meters are the monetary value and the hash associated to the value amount and the encrypted signature printed or Is encoded on the voucher; Sa tirae gaming account whereby the primary meters are the time-to-play balance and the total of the winnings associated to a patron ID or to a game session ID; a smartcard reconciliation account whereby the primary meters are a mirrored copy of the meters managed in the secure electronic module of the smancard.

Accord': g to one embodiment of the present invention, the gaming terminals (GT) 104 are advantageously configured to support functions traditionally implemented by central systems. Figure 4 illustrates an embodiment of a server-less cashless gaming session according to the-present invention. A patron 401 initially interacts with a cashier 402 to establish a cashless session 407 through to 412. The patron 401 initializes a cashless session 408 by handing over an amount of money 407 (in whatever form) to the cashier 402. The cashier 402 initializes the cashless meters 410 located on a predetermined gaming terminal 404 by issuing a credit meters transaction 409 using a cashier terminal 600. The gaming terminal 404 executes a process 410 to initialize in 2s persistent storage. the cashless meters associated with this cashless session. The gaining terminal 404 may then return a session ID 411 for later access and retrieval. The cashier 402 may complete the cashless session 408 by providing the patron 401 with an ID instrument 412 corresponding to session ID 411. The ID instrument 412 may be or include a printed ticket with text and/or encoded barcode, a printed ticket with text and/or embedded encoded magnetic strip (such as a metro ticket, for example), a magnetic ID card, a smart ID card, fingerprint recognition, voice recognition, face recognition, pahn recognition (or any biometric recognition), ID buttons, ID key-chains, a personal COMS ID No: SBMI-07116918 Received by IP Australia: Time 15:25 Date 2007-04-24 24-04-'07 15:10 FROM-DCC SYDNEY +61292621080 T-742 P012/35 F-732 S7 O ci electronic wallet, a secure handheld Computer, a secure mobile phone a secure computer Ci wrist watch, a bar-coded ticket, a bar-coded voucher or any imaginable way to associate identification means with a physical or electronic media. A PIN number may also be given for challenging the ID instrument. The identification of the cashless session may S 5 be entirely anonyiious or alternatively, may be associated with the patron's identity or membership in some group. In the later case, necessary personal identification data may C, be captured by the cashier when money is deposited 407 and are submitted together with o the credit meters 409 for persistent storage in the gaming terminal 404 during the process o 410.
Cil it The exact same cashless session 407 through 412 may be performed by making use of the automated cashier 300 instead of the cashier terminal 600 wherein the role of the cashier 402 is replaced by an automated program executed in the automated cashier.
.Suitable peripherals may be attached to the automated cashier 300 to allow for the deposit of funds, capture of information and dispensing of ID instruments.
The start 413 of a cashless game session 414 maybe identified by the patron 401 receiving the ID instrument 412. The end 436 of the cashless game session 414 may be identified by the patron 401 redeeming the credit balance of money 435 associated with his ID instrument 412, or when the credit associated with his ID is exhausted (null).
The patron 401 (who forms no part of the present invention and whose actions are only described herein to illustrate aspects of the present invention), subsequent to receiving an ID instrument 412, may execute a certain number of cashless operations associated with his ID instrument. The patron may choose any gaming terminal 403; 404, 405 or 406 to play on. In the illustration of Figure 4, the patron first chooses the gaming terminal 403 and submits his ID instrument 415 to the gaming terminal 403. If the gaming terminal 403 does not have ownership of the cashless meters associated with the ID instrument submitted,.it may immediately broadcast on the network 102 a request to acquire the cashless meters associated with the patron's ID instrument. All the gaming terminals on the network 102 intercept the broadcast. The gaming terminal 404 having ownership of the cashless meters initiates at 418 a transfer procedure 419 to transfer o3 ownership and full content of the cashless meters associated with the ID 420 to the gaming terminal 403. Upon receiving ownership and content of the cashless meters, gaming terminal 403 initializes its local game meters with the value of the cashless COMS ID No: SBMI-07116918 Received by IP Australia: Time 15:25 Date 2007-04-24 24-04-'07 15:11 FROM-DCC SYDNEY +61292621080 T-742 P013/35 F-732 0 0 Cl 8 e, meters received and enters a gaming session 421 wherein the patron may play Cl continuousiy until credit is exhausted or until the cash-out signal 422 is activated. Any winning is added to the patron's credit balance.
S. When the cash-out signal 422 is activated by the patron, the player may use the 00 s remaining of his or her credit to play on another gaming terminal or redeem the credit for Scash. A ticket showing the credit remaining may be printed if a printing device is Cl available on gaming terminal 403. In the illustration of Figure 4, patron 401 chooses to O play on gaming terminal 406 and submits his ID instrument 423 to the gaming terminal 0 406. Gaming terminal 406 does not have ownership of the cashless meters associated with the D instrument submitted. Therefore, it may immediately broadcast on the network a request to acquire the cashless meters associated with the ID instrument. All the gaming terminals on the network intercept the broadcast. The gaming terminal 403 having.ownership of the cashless meters initiates a transfer procedure 426 to transfer ownership and full content of the cashless meters associated with the ID 427 to. the is gaming terminal 406. The gaming terminal 403 may deny the transfer of the meters if credit is exhausted or already paid, thus preventing the patron from playing on gaming terminal 406. Upon receiving ownership and content of the cashless meters, gaming terminal 406 initializes its local game meters with the value of the cashless meters received and enters a gaming session 428 wherein the patron may play continuously until credit is exhausted or until the cash-out signal 429 is activated. Any winning is added to the credit balance.
When the cash-out signal 429 is activated, the player may use any remaining credit to play on another gaming terminal or may redeem the credit for cash (or for credit on another payment instrument or account). A ticket showing the credit remaining may be printed if a printing device is available on gaming terminal 406. In the illustration of Figure 4, patron 401 chooses to redeem his credit for cash. The patron submits his ID instrument at 430 to the cashier 402 who initiates a redeem process 431 that may immediately broadcast on the network a request to acquire the cashless meters associated with the ID instrument submitted 430. All the gaming terminals on the network intercept ow the broadcast. The gaming terminal 406 having ownership of the cashless meters authorizes payment by initiating a closure process 433 to terminate ownership of the cashless meters and forward the credit balance amount to pay at 434 to the cashier COMS ID No: SBMI-07116918 Received by IP Australia: Time 15:25 Date 2007-04-24 24-04-'07 15:11 FROM-DCC SYDNEY +61292621080 T-742 P014/035 F-732 0 0 terminal 402. The gaming terminal 406 may deny payment if credit is exhausted. Upon C receiving th authorization from gaming terminal the the cashier 402 then bands over the associated money 435 to the patron 401. The cashless game session associated with the ID instmrment 414 terminates 436 when the patron receives his money 435. It is 0 understood that the actions of the cashier described herein may be readily automated.
In another embodiment of the present invention, the patron may request partial C, payment of the credit available. In that case, the gaming terminal 406 having ownership o of the cashless meters associated with the patron or the patron's ID instrument authorizes O payment and initiates an update process instead of a closure process 433 in order to reflect the amount of payment made. Subsequently, the patron may continue to play on any gaming terminal or later redeem his credits at a cashier using his ID instrument.
SFor clarity of illustration, the server-less gaming session 400 of Figure 4 shows only four game terminals and one cashier operating over a peer-to-peer platform. This is an ideal scenario for small game operators. It should be apparent to those acquainted with modern network architectures that the peer-to-peer architecture disclosed herein is highly scalable and robust and that the scenario 400 can be extended to a large gaming estate comprising tens of thousands of gaming terminals and hundreds of cashier terminals or automated cashiers. Moreover, peer-to-peer mechanisms may be provided by modem operating systems such as Microsoft .NET and secure network protocols may be automatically activated by setting the appropriate security policy such as Internet Protocol Security (IPSec) or Secure Socket Layer (SSL), for example. Furthermore, cashier tenninals 600 and automated cashier 300 only require simple "stateless" .NET client applications or web browser sessions for interacting with the gaming terminals 104. The term "stateless" denotes that the software that executes in the cashier terminal 600 and in the automated cashier 300 is not.responsible for managing and recording the game session implicit state or context. The context of a software session is the ordered sequence of properties of the software objects that defines it at a particular instant in time. The context (or implicit state) of a cashless gaming session is controlled and recordedby the gaming terminal that owns the associated cashless session meters, The context ofa cashless gaming session includes the meters. The gaming terminal may advantageously store the game session context that includes the meters in a non-volatile memory for fault-tolerance.

As shown, a patron remits funds to any of the cashiers at 702, whereupon the cashier initializes meters on a predetermined gaming terminal at 704 and the cashier dispenses and ID instrument s to the patron at 706. At 708, the patron may choose to play on a gaining terminal at 710 00 or go to the cashier 734 to redeem his credit, such as shown at 732.
The patron submits his ID instrument at 712 to the selected gaming terminal that Srequests transfer of mters associated with the ID instrument from a previous gaming Sterminal 714 (the gaming terminal on which the patr6n last played), or alternatively in the case whereby the patron has just remitted funds to a cashier, from the gaming terminal on which the cashier has initialized the meters on. The previous gaming terminal may deny transfer of meters if the credit is exhausted or already paid, thus preventing the patron from playing a game.
Once the transfer of meters from a previous gaming tenrinal is successfully 1s completed, the patron may repetitively play a game at 716 as long as his credit is not exhausted as shown at 718 or the cash-out signal has not been activated 722, 726.. In case credit is exhausted 728, the patron can no longer play and the cashless game session terminates at 730.
After activating the cash-out signal 722, 724, the patron may choose another 2o gaming terminal 708 and proceed as described above. If the patron no longer wishes to play 732, he may go to a cashier 734 to redeem his credit by submitting his ID instrument 736. The cashier may use his network entry terminal to obtain payment authorization from the previous gaming terminal 738. If authorization is given, the credit amount available in the meters of the previous gaming machine may be paid by the cashier 740, and the meters at the previous gaming terminal may be updated to reflect the payment.
Traditionally and in compliance with gaming jurisdictions, gaming terminals may contain a set of highly secure persistent meters comprising essentially the patron's credit balance, the meters associated with a variety of events such as coins inserted and coins given out for a particular game, and an audit log of events for later examination if 3o required. The operation for updating the meters in accordance with the game session activity is commonly referred as metering. Metering also infers that the necessary stoi-age and access means to the meters are available. Applying modem object oriented COMS ID No: SBMI-07116918 Received by IP Australia: Time 15:25 Date 2007-04-24 24-04-'07 15:11 FROM-DCC SYDNEY +61292621080 T-742 P016/035 F-732 0 ci programming and persistent data storage techniques such as structured access to non- F volatile memory, the meters may be defined as a class that is dynamically instantiatd at run time. It may be clear to those acquainted with object programming that a multitude of instantiations of the meters class may be obtained, the only limitation being the memory available. Memory being plentiful on a typical computer unit controlling a 00 gaining terminal, a substantial number of instantiations of the meters class maybe 0 obtained.
Figure 5 illustrates the instantiation of a number of cashless meters 500 that may O be obtained on a gaming terminal 502. The gaming terminal 502 has taken ownership of the cashless meters associated with each of the patrons' submitted ID instrument for ID(x), ID(y) through and the gaming acivity in process on gaming terminal 502 is reflected in the current session cashless meters 504. The credit balance displayed to the patron currently playing corresponds to the credit balance meter 506; the other meters 508 and the audit log 510 may be reserved for use by the game operator. The cashless is meters may be frozen when the patron activates the cash-out signal.
The other meters 512, 514 and 516 are associated with gaming sessions played previously on the gaming temial 502 and are frozen. Alternatively, any of the meters 512, 514 or 516 may be associated with a new cashless session initiated by the cashier when the patron deposit funds as explained relative to steps 407 to 412. Gaming terminal 502 retain ownership of the frozen meters until ownership is requested by another gaming tenninal. If the credit remaining on these meters is exhausted, transfer of ownership to another gaming terminal is denied. If a redeem operation is requested by the cashier terminal or the automated cashier while some credit is available, the gaining terminal 502 authorizes payment, closes the meters and retains ownership of the closed 2s meters. The closed meters may be erased at a later time in order to recover storage space in accordance with the gaming operator's rules for flushing old data.
The peer-to-peer metering method object of the present invention is suitable for supporting all forms of cashless instruments such as: a a player account; an anonymous game session account; a voucher verification account; Sa time gaming account; Sa smartcard reconciliation account.

The state of the cashless session comprises essentially the 00 balance of credit available to the holder of the smartcard (the primary meters) and some 0, .auxiliary attributes (secondary meters) reflecting the games played, the time stamping of various operations, a flag indicating if the meters are owned by the gaming terminal O hosting the meters and a flag indicating if available credits have already been paid. The slaved mirrored records are used to reconcile accounting when the smartcard is used in order to detect possible forgery. Alternatively, the slaved mirrored records are used as a backup repository to pay the holder of the smartcard in case of the failure of the smartcard. When used for backup, the "slave" records may be updated by authorized software using the key that may be derived from the smartcard submitted (embossed code is for example).
The ID instrument used to derive the unique identifier key may be submitted in a variety of ways such as typing a user ID and password, keying-in a code on a keypad, presenting a bar-coded voucher, an encoded card, a secure electronic ID device or recognizing biometric features.
a. The unique identifier keys are commonly called GUI or global unique identifier.
Fault tolerance may be achieved by replicating (mirroring) cashless meters owned by a given gaming terminal to a predetermined number of other peer gaming terminals.
The gaming terminals holding replicated cashless meters are second-level owners that may be solicited in case the primary owner does not respond to the initial transfer request, whether the request is a direct one to an identified gaming terminal or broadcast to all gaming terminals on the network. For example, in case gaming terminal 403 does not obtain any reply subsequent to its transfer request broadcast 417 after a time-out, a new broadcast message explicitly soliciting secondary owners may be sent on the network. Gaming machine 403 would then accept the transfer of cashless meters from a responding secondary owner.
In another embodiment of the present invention, the gaming terminal may be able to encode information on the ID instrument submitted by the patron.

Consequently, the next used terminal may establish network communication with the previously used gaming terminal without having to rely on network broadcasting techniques to find out 00 which of the connectcd gaming terminals is the last used gaming terminal, thus reducing 0 the time to start transferring the meters and the overall network traffic. In case the last gaming terminal is not contactable, a network broadcast to find a secondary owner of the 0 meters may be initiated.

CONCLUSIONS
The invention offers a simple distributed peer-to-peer metering of cashless game sessions that is secure, robust, scalable and that requires no central system.
All the sensitive operations are carried out by the secure software (preferably -certified by a recognized test laboratory) that executes in each gaming machine. All the access points to any of the gaming terminals such as the cashier terminal or the automated cashier require only basic stateless client applications operating over a secure network protocol such as IPSec or SSL. Moreover, sophisticated relational databases are not required. Wireless laptops or palmtops may be advantageously used as entry or conrol terminals.
The invention supports all forms of cashless instruments such as Sa player account whereby primary meters are the monetary credit balance associated to a patron ID; an anonymous game session account whereby primary meters are tbe 2s monetary credit balance associated to a game session ID; a a voucher verification account whereby the primary meters are the monetary value and the hash associated to the value amount and the encrypted signature printed or encoded on the voucher; a time gaming account whereby the primary meters are the time-to-play balance and the total of.the winnings associated to a patron ID or to a game session ID; a smartcard reconciliation account whereby the primary meters are a mirrored copy of the meters managed in the secure electronic module of the smartcard.
