Description

The invention relates to a method and a system for the payment of credits by slot machines.

Field of the invention:

The invention relates to a method and a system for the payment of credits. Such methods and systems are advantageously used in the field of slot gaming, for example in casinos or in gaming halls.

Background of the invention:

From the prior art, a variety of different methods and systems for performing cashless game transactions in slot machines are known. In particular, slot machines are known, which are operated with a certain prepaid by the player credit. In this case, the slot machines are given a specific balance, this can be done by depositing coins or bills directly on the machine, but also by dropping or inserting a ticket in the slot machines or by inserting a smart card in the slot machines. Tickets or smart cards, for example, after payment of a certain amount of money by a staff of the casino or the machine can be issued. Both on the smart card and on the ticket a certain amount of money is stored in readable form for the game machine.

Alternatively, the amount of money can also be stored in a central server networked with the individual gaming machines, wherein the ticket has only one key, which refers to a storage space on the server to which the respective amount of money is stored.

With the just mentioned method of networking slot machines is also the freedom that the player receives a ticket or his smart card from the machine, either directly on the ticket or the smart card or on a central server the respective balance of the player is stored.

If the player wants to end the game, even though he still has credit available, he can effect the payment of his credit by pressing a payment unit. The payment is made either by a direct cash payment, by issuing a new ticket with a newly printed credit amount, or by accumulating on the chip card.

To be able to access the credit again, the player can insert the ticket or the stored chip card in the same main game machine or in any other machine and start another game.

If networks are used, the respective ticket contains only one key, for example a reference to a memory location in the server to which the respective amount of money has been stored. If the ticket is read in by the gaming machine, the slot machine transmits the key to the server and receives from the server the respective credit amount.

Such a procedure enables the rapid transfer of larger amounts of money without the player having to carry the sums of money with him, if necessary, the player is also motivated to higher stakes. Furthermore, it can be avoided so that each individual player would have to carry a larger amount of small change, if not round stakes or gaming winnings or credits are paid or paid back. Furthermore, this advantageous procedure also the installation of coin dispensing equipment can be avoided at each of the slot machines.

However, there is a significant disadvantage in common slot machines that the imported tickets must be kept in the game machine itself due to legal requirements. These collected original tickets must be withdrawn from the gaming machine from time to time and scanned for evidence or for tax purposes and kept in a central location.

There is thus the task of simplifying the maintenance of the individual machines, in particular to avoid a regular emptying of the read original ticket container of the machines and the necessary for evidence further processing of the original tickets.

The invention solves this problem in a method of the type mentioned above with the features of claim 1.

Furthermore, the invention solves this problem in a system of the type mentioned above with the features of claim 8.

Summary of the invention:

• die Spieleinheit bei Vorliegen eines Guthabens die Durchführung eines Spiels ermöglicht,
• bei Vorliegen eines Guthabens und Betätigung der Auszahlungseinheit ein Datensatz an den Server übermittelt wird, der die Höhe des Guthabens umfasst, -
• der Datensatz bei seinem Einlagen beim Server abgespeichert wird und im Falle der erfolgreichen Abspeicherung ein Freigabedatensatz an den Spielautomaten rückübermittelt wird,
• bei Einlagen des Freigabedatensatzes beim jeweiligen Spielautomaten ein Bestätigungsticket bereitgestellt und an den Spieler abgegeben wird,
• wobei der Datensatz vom Server zum Ausdruck zur Verfügung gehalten wird.

The invention provides a method for the payment of credits by means of a system comprising a server and a number of game machines connected to the server and operable by a player, at least one gaming machine having a game unit and a player-actuated payout unit for paying out a credit; it is envisaged that

• the game unit, in the presence of a credit allows the performance of a game,
• if a credit is available and the payment unit is activated, a record is sent to the server, which includes the amount of the credit,
• the data record is stored at the server during its deposits and in the case of a successful storage, a release data record is transmitted back to the gaming machine,
• in the case of deposits of the release data record, a confirmation ticket is made available to the respective gaming machine and given to the player,
• wherein the record is kept available for expression by the server.

With these advantageous features, the maintenance of gaming machines is greatly simplified. In particular, the time-consuming and costly scanning of the present in the machine tickets can be completely eliminated.

Another advantage results from the fact that, for example, in an error case when reading tickets in slot machines a comparatively simple tracing and determination of the amount to be paid for the player is possible.

For advantageous storage of the tickets in printed and / or electronic form can be provided that the record is printed on a printer connected to the server and / or that the record is inserted into a stored in the server electronic permanent document that is available for printing is held.

To increase the security of the gaming machines and reduce the possibility of manipulation by the player may be provided that the record printed in the time between the deposits of the record at the server and the transmission of the release record to the gaming machine and / or inserted at the end of the electronic document.

To simplify the machine readability of the printed or stored documents, it may be provided that the data record is printed at least partially in the form of a barcode on the printer or inserted into the electronic document.

In order to improve the allocation between individual players, game winnings and credits and to record the gaming behavior of individual players can be provided that the release record, in particular in the form of a barcode, is printed by the gaming machine and / or that the release record on a data connected to the slot machines and the slot machine associated storage medium, in particular a smart card is stored.

Furthermore, it can be provided that for confirmation of a credit confirmation ticket is read in before the game begins and after the end of the game the confirmation ticket is deleted and the confirmation ticket a new, possibly the record and / or the release record corresponding imprint is printed.

As a result, the number of tickets in circulation can be reduced enormously. In particular, no tickets are available in circulation or in the slot machines, which are no longer valid. As a result, on the one hand, the emptying of the machines superfluous, on the other hand are no invalidated tickets in circulation, which significantly reduces the risk of fraud.

• der beim Server einlangende Datensatz und der infolge des Einlangens des Datensatzes erstellte Freigabedatensatz einander zuordenbar im Server abgespeichert werden, und/oder
• dem Datensatz noch weitere Informationen, wie etwa eine den jeweiligen den Datensatz übermittelnden Spielautomat identifizierende Kennung und/oder die Zeit und/oder das Datum der Auszahlung des Guthabens hinzugefügt sind.

To reduce the possibility of manipulation can be provided that

• the record arriving at the server and the release record created as a result of the arrival of the record are stored in the server, and / or
• the record further information, such as an identifying the respective game record identifying the slot identifier and / or the time and / or date of payment of the balance are added.

To avoid multiple payments can be provided that after the storage of the record in the server or after the printout of the record by the server or after the issue of the confirmation ticket by the Slot machines the balance is deleted and the slot machine is prepared if necessary to carry out a new game.

Furthermore, the invention relates to a system for the payment and confirmation of credits by means of a system comprising a server and a number of slot machines connected to the server.

Furthermore, it can be provided that a printer is connected to the server, wherein the server has a print control unit which, after receipt of the data record, causes the printout of the respective data record by the printer.

This allows easy archiving of printed payment confirmations.

Furthermore, it can be provided that the payment unit has a ticket printer for printing out the release data record on a ticket carrier body, for example paper, or a chip card writing device for storing the release data record on a chip card and / or that the gaming machine is a reading device for reading tickets or of smart cards.

As a result, the reading or the issuing of tickets to the individual player is made possible in an advantageous manner.

Advantageously, the reader (25) and the output unit (22) are integrated in a common device. This simplifies the operability.

This common device is formed in a preferred embodiment of the invention for deleting and rewriting the confirmation ticket (3). As a result, the number of tickets in circulation can be reduced enormously. In particular, no tickets are available in circulation or in the slot machines, which are no longer valid. As a result, on the one hand, the emptying of the machines superfluous, on the other hand are no invalidated tickets in circulation, which significantly reduces the risk of fraud.

For improved traceability of game winnings and credit transfers and for tracking activities of individual players can be provided that a database for storing the incoming records is provided, each of the records a credit, possibly also other information such as a Identification number of the slot machine, the winning time and the winning day are assigned.

Detailed description of the figures

In the following the invention is illustrated by means of a preferred embodiment without limitation to the general inventive concept.

A preferred in Fig. 1 illustrated embodiment of a system according to the invention comprises a server 1 and a number of connected to these slot machines 2. The gaming machines 2 are connected to the server 1 by means of a network 6 and respective interfaces 27, 28. The network 6, the server 1 and the slot machines 2 are dimensioned so that the server 1 can process incoming records even if all of the slot machines 2 simultaneously transmit records to the server. The network 6 may be either a wired or a wireless network.

In principle, the communication between the server 1 and one of the slot machines 2 always takes place in the same way. The server 1 is merely designed so that it interacts with all of the slot machines 2 approximately simultaneously and can log the payouts of the individual slot machines 2 at the same time.

A credit can be booked on the slot machines 2 in different ways. Either a money can be thrown directly into the machine or chip cards or confirmation tickets can be inserted into a reader 25.

Fig. 1 shows a server 1, which is connected via a data connection 6 with several slot machines 2. It can be connected via the network 6 in addition to these illustrated slot machines 2 nor a number not shown slot machines. A typical slot machine 2 is in Fig. 2 shown.

The Indian Fig. 2 slot machine 2 shown forms a stand-alone device in the form of a standalone device and includes an approximately man-sized, roughly box-shaped housing, the upper half of the recording of a display device 30 is used, which consists in the illustrated embodiment of two large, superimposed screens 31 and 32. As Fig. 2 2, the two screens 31 and 32 are inclined to each other at an obtuse angle, with the upper screen 31 extending substantially vertically, while the lower screen 32 is inclinedly sloping towards the player. Underneath the screens 31 and 32, the housing of the gaming machine 2 has a control panel section projecting towards the player, which extends over the entire width of the device housing and has a substantially box-shaped design. In the drawn execution closes said control panel section continuously inclined in approximately the same direction to the housing section receiving the lower screen 32.

The top of the panel section houses the control panel 35, which includes a plurality of manually operable control buttons, for example in the form of push buttons. Here, mechanical switches or panels of a touch screen or other controls can be provided.

The games which can be displayed on the screens 31 and / or 32 are controlled by an electronic control device (preferably arranged in the interior of the housing), preferably in the form of a computer, which in the present case is accommodated in the interior of the housing in its lower section. On the one hand, said control device controls the display device 30 and, on the other hand, communicates with the operating keys of the control panel 35, whereby further functional components such as a profit output device, a cash input and money checking device can also be actuated by the control device.

The server 1 is advantageously accommodated in a separate secure space 200 which is separate from the space 201 in which the gaming machines 2 are located and is generally not accessible to the player. The server 1 is connected to a printer 5 and further the server 1 comprises a memory for storing a database 15, 17 of data records 41 and release records, which is described in more detail below.

If a game is carried out by a player or a user on one of the game machines 2, then the respective player has to pay for the execution of the game a specific stake or a specific fee. This fee can be paid in different ways, either money can be thrown directly into the slot machine 2, or it can be made non-cash payment methods such as the reading of confirmation tickets 3 or by smart cards. In any case, the player is entitled to perform a game by the performance of a specific fee or game. Slot machine 2 comprises a game unit 20 in which the respective credit balance 102 of the player is stored. The balance 102 may vary depending on the outcome of the game. If the player wins the game, his balance 102 can be increased or free or bonus games can be given. If the player loses the game or if the game is a paid game whose fee is charged without depending on the outcome of the game, then the player's credit balance 102 is reduced. It is advantageous in this context that the player can perform an almost unlimited number of games in a row without having to make financial transactions between the player and the slot machine. It is thus also possible to store particularly small amounts of money or non-round amounts of money in the gaming machine and only after the completion of a number of games to the player his remaining balance 102 - if still available - to pay.

• Das Guthaben 102 ist, wie in Fig. 7 dargestellt, in einem Speicher der Spieleinheit 20 gespeichert. Der Spieler gibt durch Betätigen einer Auszahlungseinheit 21, (Fig. 3, Schritt 60) etwa eines reellen oder virtuellen (über einen touch-screen) Tasters oder Schaltknopfes oder Hebels, zu verstehen, dass er das Spielen am jeweiligen Spielautomaten 2 beenden möchte und dass er sein übriges Guthaben 102 beispielsweise auf einem Papierstreifen mit einem entsprechenden, das Guthaben 102 zeigenden Aufdruck, haben möchte.

In the following, the process of disbursing the credit 102 to the player, as in FIGS Fig. 3 to 6 presented, discussed:

• The credit 102 is as in Fig. 7 represented stored in a memory of the game unit 20. The player gives by pressing a payout unit 21, ( Fig. 3 Step 60) of a real or virtual (via a touch-screen) button or switch knob or lever, to understand that he wants to stop playing on the respective slot machine 2 and that he has his remaining balance 102, for example, on a piece of paper with a corresponding, want to have the balance 102 facing print.

• Der Spielautomat 2 erzeugt einen Datensatz 41, wobei der Datensatz 41 das Guthaben 102 des Spielers sowie gegebenenfalls eine Anzahl weiterer Informationen, beispielsweise die Auszahlungszeit, eine Kennung 101 des Spielautomaten 2, die Höhe des Gewinns 103 und/oder Verlust auf diesem Spielautomaten usw. umfasst. (Fig. 3, Zweig Y) Dieser Datensatz 41 wird an eine im Spielautomaten 2 befindliche Sendeeinheit 23 geleitet (Fig. 3, Schritt 61), die den Datensatz 41 über das Netzwerk 6 an den Server 1 übermittelt. Die Sendeeinheit 23 gibt den das Guthaben 102 beinhaltenden Datensatz 41 an den Server 1 ab.

For this purpose, the following steps are performed:

• The gaming machine 2 generates a data record 41, the data record 41 comprising the player's balance 102 and possibly a number of further information, for example the payout time, an identifier 101 of the gaming machine 2, the amount of the prize 103 and / or loss on this gaming machine and so on , ( Fig. 3 Branch Y) This data record 41 is sent to a transmission unit 23 located in the gaming machine 2 ( Fig. 3 , Step 61), which transmits the data record 41 to the server 1 via the network 6. The transmitting unit 23 outputs the credit record 102 containing record 41 to the server 1 from.

In this advantageous embodiment of the invention, it is provided that a data record 41, by which the player's payment request is transmitted to the server 1, is transmitted in encrypted form from the gaming machine 2 to the server 1. In this case, the gaming machine 2 has an encryption unit (not shown in the figures) which is connected upstream of the transmission unit 23 on the machine side.

The data record 41 arrives at a server-side receiving unit 11 located in the server 1 (cf. Fig. 8 ). The server 1 has one of the server-side receiving unit 11 downstream checking unit 13, which first checks the record 41 for accuracy, completeness and authenticity.

In this case, the server 1 has a decryption unit (not shown in detail in the figures) which decrypts the data records transmitted by the gaming machine 2. The encryption unit and the decryption unit have corresponding keys, so that encrypted data transmission of the records 41 from the gaming machine 2 to the server 1 is possible. Of course, encryption is only optional, the system can also be operated without encryption.

For the upcoming printout on the printer 5, the incoming record 41 is converted by the review unit 13 into a printable form, in the present particular embodiment a barcode 107 is created ( Fig. 4 , Step 71).

The examination unit 13 initiates the storage ( Fig. 4 , Step 72) of the record 41 in the database 15 and then checks whether the storage of the record in the database 15 was successful.

In a further step, the data record 41, which is available in printable form, is forwarded to a printer memory 16 located in the server 1 and held in print for this purpose and an expression is initiated (FIG. Fig. 4 , Step 80).

As already mentioned, a server 5 is connected to the server 1, wherein the server 1 comprises a print control unit 14 which, after receiving the data record 41 in the printer memory 16, causes the printout of the respective data record to be printed by the printer 5. If only a printout is to be made on paper ( Fig. 5 , Branch "N"), so the present in the printer memory 16 in printable form record 41 is printed ( Fig. 5 , Step 83).

Alternatively, an "electronic expression" ( Fig. 5 Branch "Y") that the record 41, which is in printable form, is inserted into an electronic expression ( Fig. 5 , Step 81) and then stored and made available for later expression ( Fig. 5 , Step 82).

The "electronic expression" and the expression by means of the printer 5 can also be carried out in parallel or in succession ( Fig. 5 , Branch "B").

After checking the storage of the data record 41 and the, if necessary only electronic, expression, the credit 102 of the player on the gaming machine 2 can be deleted. ( Fig. 4 , Step 73). In some countries deletion of the player's balance 102 is not yet permitted at this time, so deletion can not occur until a step 62 after the confirmation ticket 3 is printed ( Fig. 3 , Step 62).

If the storage of the data record 41 in the database 15, 17 and the expression, if at all only electronic, is confirmed, the checking unit 13 generates a release data record 42, which is forwarded to a server-side transmitting unit 12 located in the server 1 ( Fig. 3 , Step 90). From the server-side transmission unit 12, the release data record 42 reaches the respective gaming machine 2 via the network 6.

The release record 42 includes a confirmation code 111, and optionally other information, such as the amount of the credit 102, an identifier 101 of the respective gaming machine 2 and additional information 112, which may be printed on the confirmation ticket 3.

In addition, it can be provided that between the checking unit 13 and the server-side transmitting unit 12 a further (not shown in the figures) encryption unit is arranged, which encrypts the release record 42 and the encrypted value at the output of the server-side transmitting unit 12 is available. Although such encryption is only optional, but in particular has the advantage that access by unauthorized persons to the data transmission between the server 1 and the gaming machine 2 is largely prevented. If an encryption unit is located in the server, then the game machines 2 also have a further decryption unit connected downstream of the corresponding machine-side receiving unit (24), which enables the decryption of the release data set 42 issued by the server 1. Optionally, the server 1 may each use a different key to communicate with each of the gaming machines 2.

Upon detection of the release data set 42, an output unit 22 located in the gaming machine 2 is caused to issue a confirmation ticket 3. The release record 42 is converted into a printable electronic document ( Fig. 6 , Step 90).

Optionally, a confirmation may be sent to the server 1 confirming receipt of the release record 42. In this case, the server 1 notes the confirmation in the respective release record ( Fig. 6 , Step 92).

The confirmation ticket 3 is created by the output unit 22 in the present case ( Fig. 6 , Step 93). The output unit 22 comprises a ticket printer for outputting the data stored on the release data record 42 on a ticket carrier body, for example paper, and / or a chip card writing device for storing the release data record 42 on a chip card.

The confirmation ticket 3 includes the key and optionally the other information stored in the release record 42. Specifically, the amount of the credit is printed in human-readable form on the confirmation ticket 3. Advantageously, the confirmation ticket 3 and printed via the printer 5 original ticket on a suitable identification information, so that optionally a simple comparison of the two tickets is vornehmbar, for example, in an error case when reading tickets of the gaming machine 2. These measures therefore allow in case of both for the user as well as the operator simple and quick clarification of the facts.

At the latest after the print-out of the confirmation ticket 3, the credit 102 can be deleted from the respective gaming machine 2, since the player has received a confirmation ticket 3 for taking the credit 102, which enables him to pay the credit or use the credit in further gaming machines 2 ( Fig. 3 , Step 62). The credit stored on the slot machine will be deleted.

As in Fig. 9 is illustrated, the database 15 comprises the records 1 received by the server 1 Fig. 9 illustrated particular embodiment of the invention, both the respective data record 41 and the associated release record 42 are stored in the database 15 as a common record.

Alternatively, another database 17 could be provided (as in FIG Fig. 8 shown in dashed lines), this further database 17 comprising the release data records 42, the data records 41 received by the server 1 being stored in the database 15. Between the two databases 15, 17, a unique assignment of a respective data record 41 to a release data record 42, for example via a common key or an allocation table, made so that each stored data 41 is uniquely associated with a stored release record 42.

The data records 41 preferably comprise an identifier 101 for the gaming machine 2 via which the player has initiated the respective disbursement of the credit 102, the credit 102 itself, the time 104 and the date 105 of the actuation of the disbursement unit 21, if appropriate the profit / loss 103, while the game at the slot machine 2 and possibly also the playing time on the respective gaming machine 2. If necessary, a unique attributable to the player identifier 106 can be assigned, stored by the read confirmation ticket 3 in the slot machine 2 and after paying back to the next confirmation ticket 3 is printed, so that all transactions set by a player are traceable stored.

In addition to the content of the data records 41, the release data records 42 further include a release password or a release key 111, which enables unambiguous identification and addressing of the data record 41 in the database 15 and thus access to the credit by a further gaming machine 2.

In particular, the confirmation ticket 3 can serve as a coupon or advertising medium. The release record 42 may include other, possibly randomly selected coupon information 112, which may also be printed on the confirmation ticket 3.

The data to be printed on the confirmation ticket 3 is included in the release data set 42 or may alternatively be added by the game machine 2. The release data record 42 is transmitted via the server-side transmission unit 12 to the gaming machine 2, the gaming machine 2 having a machine-side receiving unit 24 for receiving the release data record 42.

In general, the reader 25 and the output unit 22 may be formed as a common unit that both reads in and prints confirmation tickets 3.

Another non-illustrated embodiment of the invention uses re-printable confirmation tickets 3. Again, a common unit that has the functionality of the reader 25 and the output unit 22 is used. In this regard, reference is made to the US Pat. No. 5,854,477 , the content of which is hereby incorporated into this application. This common unity can be roughly in the form of in the Fig. 1 or Fig. 10 of the cited patent US 5854477 schematically be configured illustrated ticket processing unit. A confirmation ticket 3 introduced for the purpose of confirming or certifying the credit at the gaming machine 2 is deleted and rewritten by the gaming machine 2, which leads to an additional saving of confirmation tickets 3 in circulation. A new confirmation ticket 3 is issued on the carrier of the confirmation ticket 3 that has already served to confirm the credit required for the game. Each player thus has only one carrier, which is deleted and reprinted by each of the slot machines 2 after completion of the game.

By printing out the records 41 on the printer 5, the confirmation tickets 3 no longer have to be stored for purposes of proof, and their print, which no longer satisfies any proof function, can be destroyed as it were by overwriting.
