Description

GAME TABLE MANAGEMENT METHOD AND
ELECTRONIC MANAGEMENT SYSTEM THAT CAN BE USED
IN PARTICULAR FOR THE IMPLEMENTATION OF THE SAID PROCESS
The present invention relates to the management of a gaming table using gaming tokens, also called casino tokens. By game token means any element in the form of a disc or plate and representing a nominal value or not. Generally the tokens are made of rigid and scratch-resistant plastic. The tokens have various patterns in designs and colors to form a more or less complex decor and reduce the risk of falsification and / or fraudulent reproduction.

Some tokens incorporate an electronic memory circuit in which information concerning the token is stored, in particular its number or identification code and / or its numerical value. These tokens equipped with electronic memory circuits are also designated electronic memory tokens. Depending on the token models, the electronic circuits are of the PROM simple memory type, with reprogrammable memory
EEPROM or even microprocessors with memory.

In practice, the tokens are classified into two large families, the so-called "valuable" tokens which bear a fixed face value and the tokens without predetermined value called the "worthless" tokens. For "valuable" tokens, the indication is easily legible and appears permanently and cannot be erased on the token (most often by surface printing or by sub-injection into the mass of the crown of the token when it is made. by multi-injection).

"No value" tokens (or JSV tokens) are used most often in certain games, for example the game of "American roulette", but can be used in place of "value" tokens after allocation of a value by the casino or the table operator (the dealer). These "worthless" tokens ultimately have a variable value, momentarily fixed, depending on the time and place where the tokens are played. It is therefore imperative to know at all times the value assigned to each token. To do this, "worthless" tokens can be identified today by a logo and / or a dominant color and are classified by groups or by lots. For example, for American roulette, an endowment of 2,000 to 3,000 chips is generally used per table divided into eight lots, the table having its own logo and each lot or group of chips being identifiable by a distinct color. When a player decides to play at a table, the table operator assigns a group (lot or series) of chips (usually a given color) and the player decides in agreement with the dealer the value he wants to give to tokens from this group.

The value of the token is then displayed at the table to allow other players, the dealer and supervisory staff to know the value of the tokens for each group at each game table.

The present invention is particularly directed towards the management of gaming tables. In general, good management of casinos today involves regular monitoring of gaming tables (particularly at the level of entries and exits in value for performance changes tables) and monitoring (now more often video type) to reduce the risk of errors and / or fraud.

In these conditions, the management of a game table which requires frequent counting is essentially manual, long and delicate, and even susceptible to errors or sometimes fraud.

The object of the invention is to propose a method of managing a gaming table using tokens with an electronic identifier facilitating the actual management of the table for the casino operator and eliminating or significantly reducing the drawbacks mentioned above.

More particularly, the invention proposes a game table management method using at least one batch of tokens with electronic identifier, characterized by carrying out the following operations for each batch of tokens allocated to the table: - the momentary association of a value digital
given to all the tokens in the same batch, the tokens
of the same batch with an identification code
identical electronics or group code; and - real-time monitoring of inputs / outputs to or at
from the token table of each lot using
of information transmitted to a database
managed by computer from a control station
and manual entry by an operator of the
game table and at least one reading station
electronic token identification code,
associated with the game table.

Thanks to the method according to the invention, the management of the table is automated to the maximum and centralized around a database managed by computer; the reading stations can be distributed on the table at the various entry and / or exit points and / or integrated into the equipment thereof (for example token box [drop-box], sorter, token box, etc. ) so as to follow in real time the entries and exits of tokens to or from the table.

In particular, the method according to the invention is used for carrying out the real-time inventory of the number of tokens in circulation for each group.

The operator is therefore constantly aware of the number of tokens "taken out" of each group; he is in particular warned in real time of the return to the table of the last token "released" thus releasing the color for a new allocation of the group to another player and / or a new allocation of value.

Until the present invention this situation of "liberation" of color was very difficult to manage manually.

Among other applications of the management method according to the invention, the method is used for calculating the stakes lost at each game and / or gross entries in value per table, or even for calculating winnings at the table and / or control the distribution of winnings to players.

According to a first embodiment of the invention, the management method is characterized in that the game table comprises, in addition to the control and manual entry station connected to a computer, at least one of the following items of equipment each equipped with a reading of tokens with electronic identifier: - token sorter; - locker and / or drum and / or storage area for
tokens; - token box [drop-box]; - tip box; - table reader-authenticator; - table display; - a network of table setting detectors; - automatic ticket and / or card exchange station
credit and issuing tokens.

According to a variant of the invention, the method also provides for the association in the database of the identity of a player with a batch of tokens.

According to yet another variant of the invention, the method includes the use of a person identification card reader, in particular players and / or table operators.

According to yet another variant of the invention, the method comprises the use of a clock of the parking meter type in particular for the production of table history for the tokens (in quantity and value) and for the players.

According to yet another variant of the invention, the method is characterized in that the numerical value temporarily associated with a lot (or group) of tokens is written in memory of each token of the same lot (or group) by through a read / write station. This optional feature makes it possible to reduce the size of the database, to speed up certain management operations (in particular in the case where the tables are networked on a central computer-server), and to allow certain calculations at the level of '' specific table equipment (eg sorter or token box).

According to yet another variant of the invention, the method is characterized in that the number of the associated table is written in memory of each token of the same batch by means of a read / write station.

This optional feature is very interesting in terms of security and the management of several network tables.

The invention also relates to an electronic game table management system using tokens with an electronic identifier of the electronic memory type and usable in particular for the implementation of the management method presented above comprising: a computer associated with a memory of database storage; a table operator control station connected to said computer and comprising at least one keyboard and a control display; and at least one of the following table equipment each equipped with at least one read or read / write station in the electronic token memory, each reading station being connected to said computer: - token sorter; - locker and / or drum and / or storage area for
tokens; - token box [drop-box]; - tip box; - table reader-authenticator; - table display; - a network of table setting detectors; - automatic ticket and / or card exchange station
credit to issue and / or convert tokens.

It should be noted that the electronic system according to the invention allows automated management of the gaming table regardless of the type of tokens used, "valuable" tokens or "worthless" tokens. In addition, the management of a table can be centralized directly at the table level or integrated with that of a network of tables suitably connected to a central server-computer. Here again, the management of each table is made easier and security increased.

According to a first variant of the electronic management system according to the invention, the table display comprises a display provided with means forming a unitary receptacle for token, each receptacle being equipped with a reading or reading / writing station.

According to another variant, the electronic management system further comprises a reader for the identification card of persons, in particular the players and / or the table operators. Optionally, the electronic system also includes a credit card reader.

The invention also relates to a game table display usable in particular in an electronic management system defined above, characterized in that it comprises, in association with at least one reading or reading / writing station in the electronic memory of 'a token with electronic identifier, display means for displaying at the table at least one parameter of said token, for example its numerical value.

Advantageously, the display comprises a display unit provided with means forming a unitary receptacle for a token, each receptacle being equipped with a reading or reading / writing station.

The invention also relates to an automatic ticket and / or credit card exchange station for issuing and converting tokens usable in particular in an electronic management system defined above and comprising at least one reading or reading / writing station in the electronic memory of an electronic identifier token.

Other objects, advantages and characteristics of the invention will appear on reading the description which follows of an embodiment of the method according to the invention and an embodiment of the electronic management system according to the invention. given by way of nonlimiting examples - Figure 1 is a schematic representation seen

of the table display illustrated in Figure 4a.

The American roulette game table illustrated diagrammatically in FIG. 1, presented by way of nonlimiting example of the invention, comprises a roulette cylinder 10 (represented by a single circular external perimeter) and a horizontal plate 12 covered with a play mat 13 having a stake area 14 printed with a table marking (double zero model "). As illustrated in FIG. 1, the marking of stake area 14 conventionally comprises for the American roulette game a rectangular block of 36 boxes corresponding to the winning "full" numbers from 1 to 36 and arranged in 3 columns and 12 transverse lines. Attached to the central block are the boxes "zero" (marked 0) and "doublezero" (marked 00), the "dozen" boxes (marked 1-12, 2-12 and 3-12), the "column" boxes (marked
Finally . Finally, the stake area 14 comprises a row of "simple chances" boxes, that is to say the half Iberian "and" 2nd half "boxes (marked 1-18, 19-36), the" pair "boxes. , 'odd "(marked OD. and EV.) and the" red "and" black "boxes (marked with a solid diamond and a diamond with a thick border). It should be noted that the marking of the boxes of "dozen" and "simple chances" is printed upside down to face the players "J" (see Figure 1).

Around the table are the dealer "C" and the players "J". In the example illustrated, seven player places 16 are provided, distributed around the stake area 14, each player "J" having a personal receptacle 18 for his supply of chips 20, 20 ′, 20 "stored on the edge As explained above, the groups of JSV tokens of different colors are allocated to the different players after assigning a numerical value for each group of the player's choice.

According to the practice of American roulette, the players place their bets on the mat in the stakes area either "in full square" or "on the edge" (see for example chips 21, 22, 23, 24 and 25 ). Unless otherwise indicated, all the chips played and circulating around the game table are "worthless" tokens with an electronic identifier.

The croupier "C" manages the allocation of tokens from the table, allocation which is distributed in this case between 7 to 10 lots or groups of JSV tokens of different colors (the tokens all carrying the same "logo" or graphic symbol "of For this purpose the croupier has a "worthless" token reserve 26 intended to receive the stacks of JSV tokens of the various groups 28, 28 ', 28 ", a token and coin box 30 [drop-box] intended to receive money or cash and / or plaques or tokens of value against which are exchanged tokens "worthless" and a sorter 32 which can be seen in Figure 1 the chute bulk entry 34 and the receiving gutters 35 of the tokens 36, 36 ', 36 "after sorting by batch of tokens. Thus therefore the tokens 20, 28, 36 for example of red color belong to the same batch or group, there is the same for the tokens 20 ', 28', 36 'for example of yellow color and for the tokens 20 ", 28", 36 "for example e green. The game table also includes a tip box 38, a table display 40 presented in detail below, a closed transparent plastic box 42 serving as a reserve for tokens of value 44 (used either for high stakes either during the conversion of a player's "worthless" tokens when he wishes to leave the table). According to the invention, the table further comprises a control and manual entry station 46 disposed in front of the croupier's place "C" further comprising a keyboard 48, a control display 50 and a double card reader 52 intended to receive the player credit cards on the one hand and personal identification cards (players or table operators) on the other. This control station 46 is associated with a table authenticating reader 54. An automatic exchange station 56 presented below is optionally incorporated into the game table.

The invention uses advanced tokens and / or playing plates comprising an electronic identification device (also called electronic identifier) of the "contactless" type. More specifically, the token comprises an electronic circuit whose memory contains coded information specific to the token so as to allow its identification and authentication using an appropriate reading unit (for example the reading station 54). In the simplest version, the electronic circuits (not shown) of the tokens are of the microcircuit type and equipped with a non-reprogrammable memory (for example of the PROM type) with a unique identification code of 32 or 64 bits, the fields may include the token or token lot number, other information such as casino name, face value for value tokens, etc. The electronic token identification circuit also includes a circular coil peripheral antenna transmitter / receiver also located in the heart of the token and adapted to be powered by inductive coupling from the external antenna of a reading unit and / or writing as specified below in the description.

In a more elaborate version, the tokens are of evolving code and equipped with reprogrammable memory (for example of the EEPROM type) allowing reading and writing. This possibility to modify the information contained in the memory increases the degree of security of the electronic token in particular by making it possible to change over time the authentication parameters, for example the number of the table, the identity of the player, the numerical value. temporarily assigned to the token batch, the date and time of the transaction, etc. Similarly, it is possible to personalize certain areas of the memory and then to configure them reversibly or not in a defined mode of memory area with read-only access or in areas with read / write access. Optionally, the dialogue between the electronic unit controlling the read / write unit and the token is only authorized after mutual authentication, by introducing codes such as passwords and / or cryptography keys in the token and electronic unit (in particular to encrypt data during its transfer between the electronic unit and the token and vice versa).

Still within the framework of the invention, the token is equipped with a microprocessor capable of carrying out complex processing and transactions. In particular, the microcircuit is adapted to allow either the simultaneous reading and / or writing of several tokens or the discrimination between the tokens, so as to work on stacked tokens or playing plates. In the embodiment of the invention given without limitation, the electronic dialogue unit integrating the discrimination function is adapted to capture the identity of a first token in a stack or row of tokens located in the radiated field of the antenna, in this case a stack 28 of tokens from the storage area 26 or a stack 44 of tokens from the "valuable" token box 42.

It is then possible to dialogue with the token and to perform the desired read / write operations then to deactivate the token entered by sending it a command to put on standby. The electronic dialogue unit continues its interrogations in search of other tokens in the radiation area of the antenna to successively enter all the tokens present in the stack. After entering the last token, the dialog unit sends a command to reactivate all the tokens in the stack. This token discrimination function is also called the anti-collision function.

The structure and the manufacturing method of the electronic memory circuit tokens will not be described here in detail. By way of nonlimiting example, application EP-A-0694872 in the name of the applicant presents several types of token and plate structures which can be used in the context of the present invention.

The electronic management system according to the invention also comprises a table electronic unit 60 comprising computer means 66 associated with a database storage memory 90 illustrated diagrammatically in FIG. 2.

If we consider FIG. 2, the electronic table unit 60 (also called UET unit) has three main sections, an analog section 62, associated with one or more antennas 64, (by way of nonlimiting example the antenna 64 belongs to station 54 for reading and authenticating the table), a digital electronic processing section 66 and a communication section 68, associated with one or more output devices, in particular with the control display 50, and optionally to an audible or light alarm 51. Advantageously and optionally, the communication section 68 includes a bidirectional serial link interface 96 connected to a central management unit 98 (also called UCG unit).

The electronic table unit 60 associated with the antenna 64 of the reader-authenticator 54 and the display 50 is arranged on the periphery of the game table. For the reader 54 the mat 13 comprises a token control zone ( represented in dashed lines in FIG. 1 by the circle 54 ′) in front of which is presented a game token 27 with electronic identifier with memory (by way of nonlimiting example, the electronic identifier is located in the central part, or core 29 , token 27). The control station 46 in association with the reader or authenticator 54 is thus capable of authenticating game tokens incorporating an electronic identification device whose memory contains coded information specific to the token or group of tokens.

The electronic token identification device 27 comprises a transmitter / receiver with a peripheral antenna also implanted in the core 29 and adapted to be supplied by inductive coupling from the antenna 64 fixed relative to the control zone 54 '. In this configuration, simple but not limiting, the token identification code can only be read by the analog section 62 of the electronic unit 60.

The analog section 62 connected to the antenna 64 by the line 70 integrates the means for searching and reading information contained in the electronic memory device of the token 27 presented in the control zone 54 '. To do this, the analog section 62 includes a wave generator associated with the antenna 64 to radiate an RF magnetic field 83 (between 10 kHz and 20 MHz) in the control zone 54 '.

The analog section 62 also includes reception circuits activated in permanent search or polling mode to detect the presence of modulated waves 82 coming from the token 27. The signals coming from the token 27 are demodulated in a demodulator circuit to be transmitted to the input of an Analog / Digital converter 84 which forms the input circuit of the digital type electronic processing section 66. It should be noted that the electronic memory device of the token 27 is electrically powered by inductive coupling between the two antennas from the RF radiation emitted by the fixed antenna 64. Furthermore, in another version adapted to the read / write mode, the analog section 62 also includes means for writing to the memory circuit of the token, in particular a circuit modulating the waves emitted by the fixed antenna 64. Without departing from the scope of the invention, a plurality of antennas can be associated to the control zone 54 ′ and connected to the analog section 62 so as for example to increase the speed and the speed of the information transmissions between the token and the control station. By way of nonlimiting example, a variant of the invention (not shown) includes an antenna for reading and an antenna for writing.

The digital electronic processing unit 66 integrates the electronic processing means of the information transmitted by the search and reading means 62 of the information contained in the memory incorporated in the game token 27 presented in the control zone 54W, and also comprises the converter
Analog / Digital 84 (and a possible converter
Digital / Analog in case of writing function in the memory of the token), computer forming means structured around a microprocessor 86 (by way of nonlimiting example a 16 bit microprocessor), an EEPROM memory 88 for configuring the system 32 KB and a RAM 40 memory of 64 KB intended to receive a database. The updateable database can contain 2,000 identities (reference codes) of listed tokens (or lots of tokens) respectively associated with a nominal value code (with 2 characters for the unit of account and 7 numeric characters). This nominal value code is either pre-established for "value" tokens, or entered on the keyboard 48 by the operator when allocating a batch of JSV tokens to a player according to the latter's choice of value for these "worthless" tokens. To this end, the digital processing unit 66 comprises an input interface circuit 87 connected on the one hand to the keyboard 48 by the line 72 and to the double credit card and personal identification reader 52 by the line. 71.

In authentication mode, the microprocessor 86 performs the decoding of the digital signal at the output of the converter 84 to obtain a token authentication code (nO of identity of the token) and performs a comparison with the reference codes present in the memory 90. If the number belongs to the database stored in memory 90, the horn 51 is activated (beep or light flash) by an output signal from the communication means 68 and a "VALID" message appears on the screen of the display 50. The microprocessor 66 also controls the display on the screen of the display 50 of either the theoretical value of the identified token obtained from the database in memory 90 (for verification by the operator the face value written on the "value" tokens or the momentary numerical value for the "no value" tokens) or the value read from the memory of the token (which requires reprogrammable memories p for "worthless" tokens and a reader-authenticator station equipped with writing means, writing to memory "worthless" tokens being carried out when the momentary digital value is assigned). On the other hand, in the absence of either a readable signal coming from the token or an identification number in the database, the message "INVALID" appears on the display 50. In the event of the use of tokens with reprogrammable memory, the security and reliability of the operation is increased by mutual authentication between the token and the read / write station.

According to the invention, the table electronic unit 60 performs a certain number of table management functions, the microprocessor 86 performing more sophisticated computer processing such as counting the tokens of each group and determining the book value d '' a group of controlled tokens, accounting in general and statistics, the results of these operations being capable of being displayed on the display 50 and / or transmitted to a central management unit 98 comprising more powerful computer means and large capacity memories (random access memory and mass memory). Finally, the microprocessor 86 manages the circuits and components of the analog section 62 and of the communication section 68.

In addition to the interface 96 which can be of the RS232 type or
RS485, the communication section 68 includes generator interface circuits 92 for output signals to the alarm 51 and the display 50, a storage capacity and a clock / date set 94 used in particular for dating (in date and in time) an event concerning the token (for example the assignment on a given table of a group of tokens to a determined player). Finally, the table-top electronic unit 60 includes an external 220 V / 50 Hz power supply and a rechargeable battery for backing up the data in the RAM memory 90. Without departing from the scope of the invention, the output signals can be generated directly via the interface 96 to the UCG unit or even be in the form of write signals in the memory of the token, the communication means then being constituted by the write means associated with the read means.

Thanks to the configuration memory 88, the table electronic unit 60 is capable of operating autonomously. However, each UET unit 60 is capable of being connected either directly or by a network to the central management unit 98 which is capable of serving as a server, each one being a table. It is thus possible to carry out real-time management of all the tables in the same game room or casino, to transmit information and / or messages and / or instructions to each UET unit. Likewise, the presence of the clock / date circuit 94 in each UET unit allows real-time monitoring of each event or electronic transaction concerning the tokens of the game table considered.

It should be noted the advantage of the presence of the database in the RAM memory 90 of the UET unit allowing very rapid processing in real time of the verification and authentication of the token, it being understood that certain operations of management can be performed later in the UET 60 unit and / or in the UCG 98 unit. In the latter case, the UCG 98 unit interrogates the UET units at regular intervals and recovers the information stored in a buffer zone of the memory 90 of each UET unit. This solution compared to a system where the database is totally grouped in the UCG unit has the advantage of simplifying and considerably reducing the transfer of information between a UET unit and the UCG unit, of refocusing the role of the local electronic unit 60 for data acquisition and real-time monitoring of the inputs / outputs of the tokens of each group, the more complex management operations being carried out at the level of the unit
UCG. This results in significant transaction time savings for the table operator. Of course, the power of the microprocessor 86 and the capacity of the memory 90 of the unit 60 are chosen according to the extent of the management functions devolved to the UET 60.

In addition to the control and manual entry station 46 and the reader-authenticator 54, other equipment of the table is connected to the table electronic unit 60. By way of nonlimiting example, FIG. 1 shows a configuration of the electronic system management system according to the invention fairly complete according to which the analog section 62 is connected by connection lines to one or more read antennas (L mode) or read / write antennas (L / E mode) suitably associated with the table equipment given above -after to carry out the real-time entry of the inputs E and the outputs S of tokens from the table, in particular: - by line 74 to the tip box 38 (mode L or
L / E mode - input E); - by line 75 to a matrix network of antennas
detection of placing on the mat 14 (mode L or mode
L / E - I / O input), the antennas being placed in
the tray 12 of the table; - by line 76 to the cash box 30 (mode L or
mose L / E - input E); - by line 77 on the table display 40 (in L mode
or L / E - I / O entry)); - by line 78 to the token storage reserve
"without value" 26 (L mode or L / E mode - I / O entry); - via line 79 to the token storage box
"with value" 42 (L mode or L / E mode - I / O entry); - by line 80 to the inlet chute 34 of the
sorter 32 (L mode or L / E mode - I / O input); and - by line 81 at the automatic exchange station 56
(in L / E mode - I / O entry).

In the event of a multiplicity of antennas and reading points, the "input" of information by the electronic unit 60 is done automatically by successive interrogation of the reading points by rotation or by direct activation by the croupier, in particular from the keyboard. 48 or reading station 54.

It is understood that by having the most antennas at the entry and / or exit points of the tokens, the electronic management system is capable of managing the entry in real time of entries and outputs for each group of tokens. Depending on the power and the management capacity that the manufacturer wishes to give to the electronic management system, the latter must adapt the power of the digital processing unit 66 (computer) both at the level of the processing speed (frequency of the clock), word length (from 16 to 64 bits), number of microprocessors, size of RAM and optional addition of mass memory (hard drive)
The digital processing unit must also be adapted to the type of memory and to the structure of the memory fields of the tokens (PROM memory for the read-only mode or EEPROM memory for the
Readind, writing). In general, the fact of working in read / write mode requires more power at the level of the digital processing means 66 or at the level of the central computer 98.

Without departing from the scope of the invention, it is possible to reduce the number of entry / exit entry points.

By way of example, a simplified configuration includes only simple reading stations on the reader / authenticator 54, the tip box 38, the cash box 30 and at the inlet chute 34 of the sorter 32; under these conditions, the non-automated inputs / outputs of the tokens of each group are entered and communicated to the database in memory 90 by manual entry by the operator using the keyboard 48 and / or by entry from the reader-authenticator 54 per pass. manual tokens in the antenna field 64.

Of course, the electronic management system described here in its application to an American roulette game table is applicable without departing from the scope of the invention to other game tables corresponding to other types of games using tokens or plates. with electronic identifier ("no value" and / or "value token" tokens), in particular in French roulette, "Punto Banco", "CRAPS", etc. The management method according to the invention is also applicable to various game tables using "worthless" tokens with electronic identifier.

To return to American roulette, the player who wants to participate in a game declines his identity to the dealer for example by inserting his membership card and possibly his credit card in the double reader 52. The player can, at the time when he is assigned a series or group of worthless tokens (JSV tokens), fix the value he wishes to give to his JSV tokens within the limit of the maximum bet on a "full" number set by the casino. If the player does not use this option each of his chips represents the minimum bet of the table. The croupier then gives him, against exchange of money or value tokens, JSV tokens with electronic identifier which all belong to the same group. These JSV tokens are visually identifiable by batch using a drawing and / or a dominant color (to allow optical sorting of the tokens if necessary). Without limitation, JSV tokens are often identifiable by their dominant color and therefore are also called color tokens. At the time of delivery (out of the table), the croupier via the keyboard 48 enters the value momentarily associated with each token of this group of tokens and the number of tokens delivered. The croupier can also pass on the reader 54 all the tokens to be given to the player (either one by one or preferably by stack) to carry out the counting, possibly to verify the authenticity and if necessary write the value and / or d other information in memory of the token.

This series of colored JSV tokens is allocated to the player until he leaves the gaming table. These tokens must then be changed at the issuing table because they are generally not taken up at other points in the casino ( other tables, cases, exchange points
.) for lack of knowing their emission value. Colored JSV tokens are either converted into value tokens or used to credit a rechargeable payment card or a so-called electronic memory transaction plate that can be used in the casino as an exchange ticket.

The player also has the possibility during the game to give another value to his colored tokens. A new color will then be assigned to it after having changed the color tokens received previously.

All these events are entered in real time and bring about the updating of the system database (in memory 90 or in central memory of server 98): For example, the new value, the identity of the player and the date of the transaction associated with the token group; the number of tokens given to the customer is also memorized as the point of purchase or issue, etc ... In addition, the database can include a special list grouping the unitary identity of certain tokens which we seek to follow and / or find the trace of (for example lost or stolen tokens).

In the case of tokens with reprogrammable memory, the passage of the tokens on the read / write station 54 could be used to transfer information in the memory of each token such as for example the numerical value, the identity of the bearer, the place, the number of the game table, the date and time of the events, etc. In this case, it will not be necessary to use a detailed database because part of the information associated with the tokens is carried and conveyed by the tokens.

In addition, the system instantly and automatically displays the unit value assigned to the tokens.
JSV of the same group on the table display 40 next to a group token.

At the end of each game (stopping the roulette ball on the winning "full" number), the croupier picks up the stakes lost and proceeds by player to the payment of the winning combinations after having announced in detail the amount of each they. Payments are normally made from the reserve of table 26 in JSV tokens (28, 28 ', 28 "...) taken for each winning player in the prize already awarded to this player. Once again the" exits " chips from the table to the player are entered and counted in the database in memory 90 by passing to the reader 54. Exceptionally, with the authorization of the game chief, the payment of a winning combination may include plaques and value tokens 44, in particular in the case of large winnings (in this case the exit of value tokens can also be entered in quantity and / or in value).

When the croupier passes the JSV tokens on the reader 54 before giving them to the player, this action makes it possible to update the database and to memorize therein in particular the number of tokens "taken out" given to the player (and to recalculate the number of tokens of this series in circulation), to assign them the identity of the player, the date of this event etc ...

As all the JSV tokens of the same group contain common and specific information, it is possible to know at all times and for all the tokens of this group the associated value.

By connecting the sorter 32 capable of sorting the tokens by reading a sorting criterion contained in the electronic token memory to the electronic system according to the invention, it is possible not only to sort and count the tokens but to know and enter in real time the number and / or value of the tokens introduced into the sorter 32: in overall value but also in value by group of tokens. This information is interesting because in the case of American roulette for example at the end of each game, all the chips of losing bets are introduced into the chute 34 of the sorter 32; we can therefore know the gross token inputs for each game. If necessary, each token that passes through the sorter 32 can be reprogrammed (or be rewritten in memory), for example when the croupier wishes to erase the value entered in memory of the token. It should be noted that this ability to rewrite tokens in memory can alternatively be used with any other reader of the L / E type associated with an equipment of the game table and working in "Entry" mode.

By reading the additional information contained in the token, we can create an annex database in the memory 90 or in the memory of the server 98 for monitoring customer history: at such instant player X has played the value Y at table T with loss or gain of such sum S. It is also possible to manage value accounts for the players.

By connecting the tip box 38 and the coin box 30 each with a reader for tokens with electronic identifier to the electronic management system, one can know not only the number of tokens inserted in each device (entry at the table) but especially the global value entered, value which is calculated on the instantaneous value of the token at the instant when it is seized. Currently, the traditional "worthless" tokens received as tips by casino workers are immediately changed to marble "worthy" tokens.

In addition, the cash box is capable of receiving, in addition to electronic memory value tokens, electronic memory transaction plates allowing direct exchange operations at the table, the croupier being informed on his sum control display available to change into tokens, in this case JSV tokens.

By connecting to the electronic management system of table setting detectors, it is possible to know the value deposited by the player on the table and to calculate without risk of error the winnings at the table after introduction by the croupier using the keyboard 48 of the winning "full" number. The electronic management system is further improved by connecting to the UET unit 60 a winning number detector (not shown) mounted on the cylinder of the caster 10 (for example an electronic device associated with a set of optical sensors detecting the presence of the ball in one of the cylinder boxes).

The management system according to the invention makes it possible to count the tokens in real time and to continuously make an inventory of the JSV tokens of each group remaining in circulation around the table (tokens taken out) and therefore to report to the croupier the release of '' a group of tokens to be assigned again to another player (after detection of the return of the last token from the group still in circulation). For each group of tokens, the instantaneous inventory values (in quantity) can be displayed on the dealer’s control display 50, which considerably simplifies the latter’s work.

In fact, currently managing token groups
Traditional JSV poses certain constraints: a group of tokens cannot be re-used with a new value which would be greater than the previous value until all the tokens have not been played or "returned" to the table.

In addition, traditional "worthless" game tokens (without electronic memory) only have value at the table where they are played (issue table). Their reimbursement must therefore be made at this table. The use of tokens with electronic identifier and of the electronic management system according to the invention makes it possible not only to generalize the exchange points to the whole of the casino (at the other tables, at the cash desks ...), but also to simplify the foreign exchange work of the croupier because by passing the tokens on the token reader 54, the croupier knows exactly the value of the tokens given by the player (entry at the table).

The use of the electronic management system according to the invention with tokens with electronic identifier therefore allows the casino to standardize its endowments of tokens and to no longer systematically distinguish the tokens according to the tables. Indeed, the management of groups or series according to the different values is considerably simplified since it is computerized and the information can be transmitted almost immediately to all the tables networked.

Thus, the electronic system according to the invention makes it possible to assign and display the momentary value of the JSV tokens for each group of tokens and this at all times to allow the various peripheral equipment, the croupier and the other players to know in time the value of a token for each group or series of tokens. It is used with tokens with electronic identifiers. All tokens belonging to the same group have an electronic specificity which allows them to be recognized. This specificity can for example be a code identical to all the tokens of the same group. We can therefore assign a value to a token, for example, and therefore automatically associate all the tokens of the same group with the same value at an instant t. Whenever a token is presented near a reader associated with the table, the information contained therein is read and immediate entry or exit of the token at the table. According to the technology of tokens with electronic identifier, two treatments are possible for the token: - after acquisition of the electronic specificity
specific to the group, there is research in the database
system data then associated information
like for example the instantaneous value of the token; - if the token has a reprogrammable memory and if
the dealer updates the value in memory of the
token systematically at each entry into circulation,
read-only information contained in the
token lets you know its value and / or any other
parameter such as for example the identity of the player, the
place of purchase, table number etc ...

The system according to the invention therefore makes it possible to "manage" all the tokens of this group with this same value without having to systematically re-specify it. This means that if a token is "read" by a suitable device itself connected to this system, it is possible to perform management processing on the value of the token, the value assigned at this time t.

Thus, the electronic management system according to the invention allows, in addition to implementing the method according to the invention for JSV tokens, by direct reading for value tokens or after assignment of a momentary numerical value for each group of JSV tokens, to carry out real-time monitoring of input / output in tokens or in value to or from the game table in association with a computer-managed database. The management of each table is thereby facilitated and the risks of errors or fraud reduced.

The electronic management system according to the invention also makes it possible to carry out other game table management operations relating in particular to value tokens with electronic memory, for example for managing endowments of tokens specifically allocated to promotional or particular operations of the casinos. The casinos thus use tokens of fixed value with validity limited in time (one or two specific days), with validity limited in the space of the casino (at tables or in reserved rooms) or with validity limited to certain players; in particular to know the gross entries coming from a group of players led to the casino by an organization of trips or leisures, the casinos are brought to make bet these players with special tokens identifiable but not negotiable elsewhere (tokens "junket" ), the winning bets being paid in classic value tokens. Of course it is possible with the electronic management system according to the invention to manage at each authorized table these particular tokens using the system database after having associated them with the desired management characteristic (s) (validity period , authorized tables, identity of the player or organization responsible for the players' stay in the casino), these management characteristics being possibly written in the memory of these particular tokens, for tokens with reprogrammable memory.

To complete the presentation of the electronic game table management system according to the invention, details are given on the various antennas used and on their integration into the various game table equipment presented above.

As regards the reader / authenticator station 54, FIG. 3 shows a view in partial section of the plate 12 substantially at the level of the token 27.

Centered on the reading area 54 ′, a cylindrical recess 100 is made in the plate 12 perpendicular to it up to about 0.5 cm from the mat 13. As illustrated in FIG. 3, the recess 100 receives the fixed antenna 64 (6 mm in diameter) in the form of a winding 105 of copper wire around a cylindrical rod of ferrite 102 about 2 cm long, the turns of the antenna 64 extending substantially parallel to the plate 12. In practice, the depth of the recess is defined according to the materials used for the plate 12 on the one hand and according to the power radiated by the antenna 64 on the other hand, for obtain a sufficient reading area. In the case where it is necessary to circumscribe the reading area to avoid interference between several tokens, or between several antennas, an additional ferrite (not shown) is placed around the antenna to confine the electromagnetic magnetic field radiated by that -this.

In addition to the reading station 54, this type of antenna, well suited for reading stacked tokens (the tokens then having the discrimination function), is used for the matrix network for detecting bets on the stakes area 14 , the storage area 26 and the valuable token box 42. However, with regard to the latter two devices, it may be advantageous to use lockers and / or vertical storage drums (not shown) comprising a movable frame. defining several rows or columns for tokens each fitted with at least one antenna either of the wound type with circular winding illustrated in FIG. 3, or of the wound type with large turns to surround the entire column or row of tokens.

With regard to the tip box 38, the token box 30 and the sorter 32, an antenna with coiled coils of approximately 4 to 5 cm in diameter is used, placed opposite a arranged reading area. in the token supply duct, the device further comprising means for temporarily stopping the token in front of the reading zone and controlled by the electronic unit 60.

The table display 40 illustrated in FIGS. 4a and 4b comprises a vertical frame 110 in which are provided seven flat-bottomed cylindrical cavities 112a to 112g intended to receive a colored token from each series attributed to a player. To facilitate the placement and removal of the tokens, each cavity 112a-112g is surmounted by a crescent-shaped recess 113a-113g as illustrated in FIGS. 4a and 4b. In the bottom wall of each cavity or unitary token receptacle (for example 112a), is disposed a small circular coil antenna (for example 114a) intended to allow either the reading of the identification code of the token placed by the croupier ( for example the token 118 only shown in FIG. 4b), or the direct reading of the value of the token in the case of a token with reprogrammable memory. The value of the token transmitted by the database in memory 90 or directly read is then displayed on the display screen (for example 116a) opposite the corresponding cavity, in this case the screen 116a displays a value $ 5 for tokens in the 118 token series.

 It should be noted that, depending on the complexity of the electronic management system, the cavity-antenna assemblies can serve as a reading or reading / writing station for the tokens, in parallel with the reader-authenticator station 54.

The automatic exchange station 56 (not shown) allows from cash, credit cards or transaction plates to distribute to the player casino chips, the player entering his credit card, his transaction plate or cash to pay the amount equivalent to the tokens to be received. According to the invention, the exchange station includes a reading or reading / writing station for tokens with electronic identifier, a control display and a keyboard for entering the player's choices (total sum debited, number of tokens purchased, unit value of token). The reading station of the automatic exchange station is connected to the electronic unit 60 so that all the transactions and the "inputs / outputs" of tokens are controlled by the computer 66, recorded in the database in memory 90 and available on the dealer’s control display 50. The player is therefore allocated a lot of tokens and a desired number of tokens, after entering the numerical value chosen for his series of tokens and paying the equivalent.

In the case of tokens with reprogrammable memory, the exchange station writes in memory the distributed tokens, their numerical value, the date and time of the transaction, the identity of the player, the table and / or station number. change, etc. The automatic exchange station can also convert tokens into cash or credit a card or a transaction plate. After entering the tokens in the machine, the latter detects the presence of the electronic token, authenticates it, reads its value in the memory area (or obtains it from the database), and converts this value into cash or credit card or plate.
