Description

Cross - reference to related applications

[0001] In this application, the benefit of Patent Application No. 2022 - 003598 filed in Japan on January 13, 2022 is claimed, and the content of said application is hereby incorporated by reference.

Technical Field

[0002] The present invention relates to a management system for managing game currency used for betting in games at casinos and to game currency.

Background Art

[0003] In casino facilities, games are played using game currency. In casino facilities, game currency is a valuable item that can be exchanged for cash, and high - level security management is required, and it is necessary to prevent illegal acts such as forgery and money laundering. For the management of game currency, game currency incorporating RFID components is used. By incorporating RFID components into game currency and reading the RFID components at game tables, cashiers, etc., it is possible to determine the authenticity and track game currency in the game facility.

[0004] Stable reading of the RFID components incorporated in game currency has always been a problem. When radio waves are not transmitted well between the RFID reader and the RFID components, it may not be possible to accurately read the RFID components. Also, the RFID components incorporated in game currency may malfunction, and in this case, it becomes impossible to read the RFID components with the RFID reader.

[0005] On the other hand, there are situations where advanced management using RFID tags is not necessary, but more reliable detection of game currency is desired. For example, if taking game currency out of a game facility's game floor is prohibited, it would be desirable to detect the game currency a player is attempting to take out at the gate without contact. Also, in some cases, taking out game currency from the game floor is permitted on the condition that the player declares it. In this case as well, it would be desirable to detect the game currency a player is attempting to take out without declaring it, without contact.

[0006] U.S. Patent No. 9183479 discloses a gaming chip that incorporates a microchip and EM materials such as coils and metal foil to prevent employees from fraudulently removing valuable tokens from the game floor.

[0007] However, U.S. Patent No. 9183479 does not describe how to use EM signals from EM materials and RFID signals from IC chips to manage the gaming chip. Furthermore, U.S. Patent No. 9183479 states that the gaming chip must be the same size as or larger than the antenna to avoid interference between EM signals and RFID signals. Thus, U.S. Patent No. 9183479 imposes limitations on the size and placement of the EM coil and antenna. [Overview of the Initiative]

[0008] Therefore, the present invention aims to provide a management system for managing game currency using EM wire and RFID components, and game currency that can detect EM wire and read RFID components.

[0009] One embodiment of the present invention is a management system for managing game currency used for betting in casino games, wherein the game currency incorporates an EM wire and an RFID component that stores information, and the management system comprises a gate equipped with an EM detection system that detects the presence of the game currency held by a passerby by detecting the presence of the EM wire, and an RFID reading system that reads the information from the RFID component, wherein the RFID reading system is configured to read information from the RFID component of the game currency declared by the passerby, or to read the information from the RFID component of the game currency detected when the EM wire is detected by the EM detection system.

[0010] This configuration allows for the detection or examination of a player's game currency as it passes through a gate, using EM wires and RFID components embedded in the game currency.

[0011] The above-described management system may be a system for managing the game currency which is permitted to be taken out of or brought into the gate, subject to declaration, the RFID reading system may read information from the RFID component of the game currency declared by the passerby, and the management system may further include a registration device that stores the information of the game currency read by the RFID reading system in a database as information of the game currency to be taken out or brought in.

[0012] This configuration allows for effective management of game currency when it is permitted to take game currency outside or inside the gate, subject to declaration.

[0013] In the management system described above, the RFID reading system may read information from the RFID component of the game currency brought into the gate, the registration device may store information of the game currency taken out of the gate by the passerby in the database as information of the game currency to be taken out, and the management system may further include an inspection device that checks whether the information of the game currency read by the RFID reading system and brought into the gate by the passerby is stored in the database as information of the game currency to be taken out.

[0014] This configuration allows for verification that game currency brought into the gate has been taken out of the gate through the proper procedures.

[0015] The above-described management system may be a system for managing the game currency which is prohibited from being taken outside the gate or brought inside the gate, the RFID reading system may read the information from the RFID component of the game currency which has been detected by the EM detection system when the EM wire is detected, and the management system may further include an inspection device which checks whether the information of the game currency read by the RFID reading system is stored in a database.

[0016] This configuration allows for verification of whether game currency is legitimate if it is taken out or brought into the gate in violation of a prohibition against taking game currency outside or inside the gate.

[0017] In the management system described above, the gate may be a player gate on the casino's game floor, a staff gate in the casino's security area, or a staff gate in a manufacturing facility that produces the game currency.

[0018] A game currency according to one aspect of the present invention comprises a first resin capsule member, a second resin capsule member, an EM wire, an RFID component, a first resin decal, a second resin decal, and a resin outer peripheral portion, wherein the first capsule member and the second capsule member are joined to form a capsule, the RFID component comprises an IC chip that stores information in a readable manner and an antenna connected to the IC chip, the outer peripheral portion is arranged on the outer periphery of the capsule, the first decal and the second decal are provided on the outside of the first capsule member and the second capsule member, respectively, the RFID component is arranged inside the capsule, the EM wire is arranged between the first decal and the second decal, the EM wire and the RFID component are arranged apart from each other in the thickness direction of the game currency, the presence of the game currency can be detected by the EM wire, and the information can be read from the RFID component.

[0019] This configuration ensures that the EM wire and RFID components are positioned apart from each other in the thickness direction of the game currency. Therefore, even if the EM wire and RFID components overlap when viewed from the thickness direction, they will not interfere with each other or short-circuit. This increases the freedom of shape and arrangement for the EM wire and RFID components, enabling the realization of shapes and arrangements that are advantageous for detection or reading of the EM wire and RFID components.

[0020] In the above-described game currency, the EM wire and the RFID component may be arranged to overlap each other when viewed from the thickness direction.

[0021] As described above, the EM wire and RFID components are positioned apart from each other in the thickness direction of the game currency. Therefore, even if they are arranged to overlap each other when viewed from the thickness direction as in this configuration, the EM wire and RFID components will not interfere with each other or short-circuit. Furthermore, if the EM wire is formed in a coil shape, the surface area of ​​the coil can be made wider, and the EM wire can be made longer.

[0022] In the above game currency, the EM wire may be disposed within the capsule.

[0023] With this configuration, the EM wire is protected by the capsule.

[0024] In the above game currency, the EM wire may be held by a first sheet-like base material to form an EM sheet, and the EM sheet may be fixed to the first capsule member or the second capsule member.

[0025] With this configuration, since the EM wire is fixed to the capsule, the EM wire will not collide with the capsule member inside the capsule and malfunction, nor will the EM wire move freely inside the capsule and make a rattling sound.

[0026] In the above game currency, the RFID component may be held by a second sheet-like base material to form an RFID sheet, and the RFID sheet may be fixed to the first capsule member or the second capsule member.

[0027] With this configuration, since the RFID component is fixed to the capsule, the RFID component will not collide with the capsule member inside the capsule and malfunction, nor will the RFID component move freely inside the capsule and make a rattling sound.

[0028] In the above game currency, the EM wire may be held by a first sheet-like base material to form an EM sheet, the RFID component may be held by a second sheet-like base material to form an RFID sheet, the RFID sheet has at least one adhesive surface larger than the EM sheet, and the RFID sheet may be adhered to the EM sheet and the first capsule member or the second capsule member from above the EM sheet with the adhesive surface.

[0029] With this configuration, both the EM wire and the RFID component are protected by the capsule and fixed within the capsule, so that the EM wire and the RFID component do not collide with the capsule member within the capsule and malfunction, and the EM wire and the RFID component do not move freely within the capsule to produce rattling noises.

[0030] In the above game currency, the EM wire may be made of amorphous material.

[0031] In the above game currency, the EM wire may be a single or double or more endless circular wire.

[0032] In the above game currency, the EM sheet may be configured, and the EM wire may be a plurality of wires arranged in the same direction on the first sheet-like base material.

[0033] In the above game currency, the EM wire may include a plurality of first wire groups arranged in the same direction on the first surface of the first sheet-like base material, and a plurality of second wire groups arranged on the second surface of the first sheet-like base material in a direction intersecting the first wire groups.

[0034] In the above game currency, casino information may be printed on the first decal and the second decal.

[0035] In the above game currency, the IC chip may store at least one of the chip ID of the game currency and the denomination information.

[0036] In the above game currency, the EM wire and the RFID component may be built into the capsule in a non-contact state.

[0037] With this configuration, the EM wire and the RFID component are protected by the capsule, and interference or short circuit does not occur due to the contact between the EM wire and the RFID component.

[0039] The embodiments of the present invention will be described below with reference to examples. The following description is merely illustrative of forms in which the present invention can be carried out, and is not intended to limit the scope of protection of the present invention. (Composition of game currency)

[0040] Figure 1 is a cross-sectional view of a game currency according to an embodiment of the present invention. The game currency 100 is disc-shaped. The game currency 100 comprises a first capsule member 11, a second capsule member 12, an EM sheet 13, an RFID sheet 14, a first decal 22, a second decal 23, and an outer peripheral portion 21. The game currency 100 has a cross-sectional structure in which the first decal 22, the first capsule member 11, the EM sheet 13, the RFID sheet 14, the second capsule member 12, and the second decal 23 are stacked in this order. Note that the game currency 100 is not limited to a disc shape, but may be rectangular or have other shapes.

[0041] The first capsule member 11 and the second capsule member 12 are joined together to form a capsule 10. The first capsule member 11 and the second capsule member 12 have the same shape, and are tray-shaped with flanges on their edges. The flanges of the first capsule member 11 and the flanges of the second capsule member 12 are bonded to each other with adhesive to form a capsule 10 with a sealed space inside. The first capsule member 11 and the second capsule member 12 may be joined to each other by engagement, welding, press-fitting, locking, or other methods.

[0042] The EM sheet 13 comprises a first sheet-like base material 132 made of a plastic sheet as an insulator, and an amorphous wire 131 as an EM wire provided on the first sheet-like base material 132. The amorphous wire 131 is fixed to the first sheet-like base material 132 by adhesive. The EM sheet 13 is fixed to the inner surface of the first capsule member 11 with the amorphous wire 131 facing outwards. As a result, the EM sheet 13 is placed in the internal space of the capsule 10.

[0043] Figure 2 is a plan view showing the configuration of an EM sheet according to an embodiment of the present invention. The EM sheet 13 is constructed by arranging amorphous wires 131, which are formed in a circle smaller than the first sheet-like substrate 132, on a circular first sheet-like substrate 132. The amorphous wires 131 are coiled wires formed in a coil shape with approximately 1 to 4 turns.

[0044] Returning to Figure 1, the RFID sheet 14 comprises a second sheet-like substrate 142, an RFID component 141 provided on the second sheet-like substrate 142, and an adhesive layer 143 provided on the RFID component 141. The RFID component 141 is adhered to the second sheet-like substrate 142 by the adhesive layer 143.

[0045] The RFID sheet 14 has a larger diameter than the EM sheet 13, and is adhered to the inner surface of the first capsule member 11 with the side having the adhesive layer 143 facing outwards, i.e., opposite to the EM sheet 13. As a result, the EM sheet 13 is fixed to the inner surface of the first capsule member 11 by the RFID sheet 14. The adhesive layer 143 of the RFID sheet 14 adheres to the inner surface of the first capsule member 11 at the peripheral portion that extends beyond the EM sheet 13. As a result, the EM sheet 13 and the RFID sheet 14 are positioned in a fixed state within the internal space of the capsule 10.

[0046] As described above, the EM sheet 13 is fixed to the inner surface of the first capsule member 11, and the RFID sheet 14 is also fixed to the inner surface of the first capsule member 11, so both the EM sheet 13 and the RFID sheet 14 are enclosed in the capsule 10. At this time, at least the first sheet-like base material 132 of the EM sheet 13 is interposed between the EM sheet 13 and the RFID sheet 14, so the amorphous wire 131 and the RFID component 141 do not come into contact with each other and are housed inside the capsule 10 at a distance in the thickness direction of the game currency 100.

[0047] Figure 3 is a plan view showing the configuration of an RFID sheet according to an embodiment of the present invention. In the RFID sheet 14, an RFID component 141 is placed on a circular second sheet-like substrate 142, and an adhesive layer 143 is provided over the entire surface of the second sheet-like substrate 142. The RFID component 141 includes an antenna 1411 formed in the shape of a circle smaller than the second sheet-like substrate 142, and an IC chip 1412 connected to the antenna 1411. The IC chip 1412 includes a rectifier circuit, a control unit, and a memory. The RFID component 141 is fixed to the second sheet-like substrate 142 by being sandwiched between the second sheet-like substrate 142 and the adhesive layer 143.

[0048] The memory of the IC chip 1412 stores information about the casino facility where the game currency is used, information about the value (denomination) of the game currency (e.g., $10, $100, $1000, etc.), a chip ID that uniquely identifies the game currency, and manufacturing information about the game currency (e.g., date of manufacture, manufacturing plant, etc.).

[0049] Returning to Figure 1, the outer periphery 21 is provided around the entire circumference of the capsule 10, which contains the EM sheet 13 and the RFID sheet 14. The outer periphery 21 is made of, for example, resin. The central parts of the upper and lower surfaces of the capsule 10 are exposed from the donut-shaped outer periphery 21. The first decal 22 and the second decal 23 are bonded to the central parts of these exposed upper and lower surfaces of the capsule 10, respectively. The first decal 22 is fixed to the outer surface of the first capsule member 11 by adhesive 221, and the second decal 23 is fixed to the outer surface of the second capsule member 12 by adhesive 231.

[0050] Figure 4 is a perspective view of a game currency according to an embodiment of the present invention. The first decal 22 and the second decal 23 are printed with information on the value (denomination) of the game currency 100 (in the example in Figure 4, "$100") and information on the casino facility where the game currency 100 is used (in the example in Figure 4, "ABC Casino"). (Configuration of the detection system)

[0051] Figure 5 shows the configuration of a detection system according to an embodiment of the present invention. In the example shown in Figure 5, the management system 40 is installed at the entrance / exit for players on the game floor of a casino facility. The management system 40 includes a security gate 41 for players. The security gate 41 includes left and right pillars 411 and 412. The left and right pillars 411 and 412 each have a transmitting antenna 421 and a receiving antenna 422 built in.

[0052] The transmitting antenna 421 and the receiving antenna 422 are each connected to a detection device 423. The transmitting antenna 421, the receiving antenna 422, and the detection device 423 constitute an EM detection system 42 that detects the presence of the amorphous wire 131. A control device 44 is connected to the detection device 423. The transmitting antenna 421 generates a magnetic field toward the receiving antenna 422.

[0053] If an amorphous wire 131 is present between the transmitting antenna 421 and the receiving antenna 422, the magnetic field generated by the transmitting antenna 421 will be distorted, and the magnetic field received by the receiving antenna 422 will also be distorted. The detection device 423 detects this distortion in the received magnetic field and reports it to the control device 44. In response to the report from the detection device 423, the control device 44 detects that a game currency 100 containing an amorphous wire 131 is present in the security gate 41.

[0054] The RFID reading system 47 includes an antenna and an RFID reader (not shown). When game currency 100 is placed within the reading area of ​​the antenna, the RFID reading system 47 reads information from the RFID component 141 embedded in the game currency 100. The RFID reading system 47 is installed near the security gate 41. The RFID reading system 47 does not need to read information from the RFID component 141 of game currency 100 held by a player passing through the security gate 41, but it can read information from the RFID component 141 of game currency 100 offered by players P before and after passing through the security gate 41 and placed within the reading area of ​​the antenna.

[0055] The control device 44 is connected to a buzzer device 45 and a lamp device 46. When the presence of game currency 100 is detected in the EM detection system 42, the control device 44 controls the buzzer device 45 to output a buzzer sound and controls the lamp device 46 to light up the lamp.

[0056] A database 48 is further connected to the control device 44. The control device 44 functions as a registration device that updates the database 48 by writing information to it, and also functions as an inspection device that checks the game currency 100 by referring to the information stored in the database 48. The database 48 stores data related to the game currency 100.

[0057] Figure 6 shows the data stored in the database of an embodiment of the present invention. As shown in Figure 6, the database 48 stores, for each 100 game currency units, identification information such as the chip ID 481 of the game currency, type (denomination) information 482, casino information 483 which is information about the casino in which it is used, owner information 484, withdrawal information 485, bringing-in information 486, and security information 487.

[0058] Owner information 484 is updated whenever the ownership of game currency 100 changes. For example, when a player P purchases game currency 100, the owner information 484 for that game currency 100 is updated to the player ID of the purchasing player P. If the player bets the game currency 100 in a game and loses, and the currency is recovered by the dealer, the owner information 484 is updated to indicate that it is owned by the casino. Also, if player P participates in a game and wins, and the game currency 100 owned by the casino is paid to the winning player P, the owner information 484 for that game currency 100 is updated to the player ID of the winning player P.

[0059] The removal information 485 is used when it is permitted to take game currency 100 out of the game floor through security gate 41. The removal information 485 may include information such as the date and time of removal, information about the security gate 41 to which the currency is taken, and the player ID of player P who is taking the currency. The import information 486 is used when it is permitted to bring game currency 100 into the game floor through security gate 41. The import information 486 may include information such as the date and time of import, information about the security gate 41 to which the currency is taken, and the player ID of player P who is importing the currency.

[0060] Security information 487 is information for the security management of game currency 100. Security information 487 stores the security status of game currency 100. The security status can be "Available" (indicating it can be used without problems on the game floor), "Suspected" (indicating it is suspected of being fraudulent or malfunctioning), "Unavailable" (indicating it is prohibited from being used on the game floor), or "Out of the game" (indicating it has been taken out of the game floor).

[0061] A player identification system 49 is further connected to the control device 44. The player identification system 49 identifies player P as he passes through the security gate 41. The player identification system 49 may identify player P by reading the member card that player P is carrying. The player identification system 49 may also be a system that identifies player P by image recognition using a camera and an image recognition device. In this case, the camera photographs the face of player P as he attempts to pass through the security gate 41, and the image recognition device performs facial recognition. The player identification system 49 identifies player P by player ID and outputs the player ID to the control device 44 as a result of the identification.

[0062] The operation of the management system 40, configured as described above, will now be explained. Below, the operation of the management system 40 will be explained separately for cases where the removal of game currency 100 from the game floor and the bringing of game currency 100 into the game floor are prohibited, and for cases where the removal of game currency 100 from the game floor and the bringing of game currency 100 into the game floor are permitted. <Cases where bringing in or taking out game currency is prohibited>

[0063] If player P is prohibited from taking game currency 100 out of the game floor, the management system 40 will be used to detect the game currency 100 that player P is trying to take out of the game floor as player P passes through the security gate 41 and leaves the game floor.

[0064] Security staff are stationed near security gate 41. The player identification system 49 identifies player P as they pass through security gate 41. If the player identification system 49 identifies players using the member card held by player P, the security staff will take the member card from player P as they attempt to pass through security gate 41 and use the player identification system 49 to identify player P's player ID.

[0065] Furthermore, if the player identification system 49 is a system that identifies the player ID of player P by facial recognition using a camera and an image recognition device, the camera will capture the face of player P as he passes through the security gate 41, and the image recognition device will perform facial recognition on the facial image of player P as he passes through the security gate 41.

[0066] If player P is in possession of game currency 100 as they pass through security gate 41, the management system 40 will detect the game currency 100, the buzzer device 45 will emit a buzzer sound, and the lamp device 46 will light up. Upon confirming the buzzer sound from the buzzer device 45 and the illumination of the lamp device 46, security staff will stop player P who is trying to take the game currency 100 and urge them to exchange the game currency 100 they are possessing for cash. At this time, security staff will place the game currency 100 that player P was trying to take into the reading area of ​​the RFID reading system 47 and read the RFID component 141.

[0067] If there are multiple game currency 100s, the RFID reading system 47 reads the RFID components 141 of multiple game currency 100s simultaneously. As described above, the IC chip 1412 of the RFID component 141 stores the chip ID of the game currency 100. The control device 44, acting as an inspection device, refers to the database 48 and inspects the data of the game currency 100 corresponding to the chip ID read by the RFID reading system 47.

[0068] The control device 44, acting as an inspection device, checks whether the game currency 100 corresponding to the chip ID read by the RFID reading system 47 is the game currency 100 that should be on the game floor inside the security gate 41. Specifically, the control device 44 first determines whether the chip ID read by the RFID reading system 47 is stored in the database 48. If the chip ID is stored in the database 48, the control device 44, acting as an inspection device, checks whether the security status of those game currencies 100 is "available".

[0069] Furthermore, the control device 44 determines whether the player identified by the player identification system 49 matches the owner information associated with the chip ID read from the RFID component 141 by the RFID reading system 47 in the database 48. In other words, the control device 44 determines whether the person actually possessing the game currency 100 is the player P who is stored as the owner in the database 48.

[0070] If the security staff finds that the player identified by the player identification system 49 matches the owner information stored in the database, and the security status referenced by the control device 44 is "available," they prompt player P to cash out at the exchange counter. If the security staff finds that the player identified by the player identification system 49 does not match the owner information stored in the database 48, or if the security status is not "available," they determine that there has been fraud.

[0071] A display device (not shown) is connected to the control device 44. The control device 44 performs checks to verify whether the chip ID is stored in the database 48, whether the security status is "available", and whether the player matches, and displays the results of these checks on the display device. Security staff check the display on the display device and take appropriate corrective measures if the chip ID is not stored in the database 48, the security status is not "available", or the player does not match.

[0072] If player P is prohibited from taking game currency 100 out of the game floor, then player P is also prohibited from bringing game currency 100 into the game floor from outside. Therefore, even for player P who passes through security gate 41 and enters the game floor, the management system 40 is used to detect the game currency 100 that player P is trying to bring into the game floor, and if game currency 100 is detected, the control device 44 acts as an inspection device and inspects the detected game currency 100 in the same manner as described above. <Cases where bringing in and taking out game currency is permitted upon declaration>

[0073] When player P leaves the game floor, they declare the game currency 100 they intend to take out before reaching security gate 41, and the RFID reader system 47 reads the game currency 100. Player P then passes through security gate 41 without the game currency 100. After passing through security gate 41, player P can leave the game floor with the game currency 100 that was read by the RFID reader system 47.

[0074] The RFID reading system 47 reads the chip ID stored in memory from the RFID sheet 14 of the game currency 100 to be taken out. If there are multiple game currency 100, the RFID reading system 47 reads them simultaneously and obtains multiple chip IDs. The RFID reading system 47 outputs the read chip IDs to the control device 44. The control device 44, acting as a registration device, stores the information of the game currency 100 to be taken out in the database 48.

[0075] If player P passes through security gate 41 without handing over all of the game currency 100, the EM detection system 42 will detect the game currency 100, the buzzer device 45 will emit a buzzer sound, and the lamp device 46 will light up. Upon confirming the buzzer sound from the buzzer device 45 and the light device 46 is lit, security staff will stop player P who is trying to take out the game currency 100 and ask them to hand over the game currency 100 they are holding. The RFID reading system 47 will then read the game currency 100 that player P has handed over.

[0076] As described above, the management system 40 can read the RFID component 141 of the declared game currency 100 with the RFID reading system 47, and also detect undeclared game currency 100 at the security gate 41 and read the RFID component 141 with the RFID reading system 47, thereby registering the game currency 100 to be taken out as described below.

[0077] The player identification system 49 identifies player P who is attempting to take out game currency 100. The control device 44 refers to the database 48 for the read chip ID and determines whether the owner information 484 matches the player identified by the player identification system 49.

[0078] Furthermore, the control device 44 checks the database 48 for the read chip ID to see if the chip ID is stored in the database 48. If the chip ID is stored in the database 48, it further checks whether the security status associated with that chip ID is "available".

[0079] The control device 44 further refers to the take-out information 485 and bring-in information 486 in the database 48 with respect to the chip ID read by the RFID reading system 47 to determine whether the game currency 100 is indeed on the game floor. That is, if the take-out information 485 is not recorded, or if past take-out information 485 is recorded but later bring-in information 486 is recorded, the control device 44 determines that the game currency 100 should be on the game floor and permits the take-out of the game currency 100 from the game floor.

[0080] On the other hand, if past removal information 485 is recorded but subsequent bring-in information 486 is not recorded, the control device 44 determines that the game currency 100 was not brought in through a proper declaration and prohibits the removal of this game currency 100 from the game floor.

[0081] If the player matches and the security status is "available," the control device 44, as a registered device, updates the withdrawal information 485 in the database 48 for the game currency 100. Specifically, the control device 44 records the date and time of withdrawal, the security gate 41 information, and the player ID of the player P making the withdrawal as the withdrawal information 485 in the database 48. The control device 44 also updates the security status to "withdrawal in progress."

[0082] In this embodiment, as shown in Figure 6, the database 48 includes take-out information 485 in the data for each game currency 100, and when game currency 100 is taken out, this take-out information 485 is updated and the security status is updated to "in transit". In addition to this, or instead, the control device 44 may associate the player ID of player P identified by the player identification system 49 with the chip ID of the game currency 100 obtained from the RFID reading system 47 and store it in the database 48.

[0083] If it is permitted to take 100 game currency out of the game floor on the condition of declaration, then it is also permitted to bring 100 game currency into the game floor. When player P brings 100 game currency into the game floor, they present the 100 game currency before passing through security gate 41. RFID reading system 47 reads the presented 100 game currency. Player identification system 49 identifies player P entering the game floor.

[0084] The control device 44, using the chip ID read by the RFID reading system 47, refers to the take-out information 485 and the bring-in information 486 in the database 48 to determine whether the game currency 100 has indeed been taken out. That is, if take-out information 485 is recorded but bring-in information 486 is not, or if past bring-in information 486 is recorded but later take-out information 485 is recorded, the control device 44 determines that the game currency 100 was taken out through a proper declaration and permits the bringing of this game currency 100 into the game floor.

[0085] On the other hand, if the take-out information 485 is not recorded, or if past take-out information 485 is recorded but later bring-in information 486 is recorded, the control device 44 determines that the game currency 100 was not taken out through a proper declaration and prohibits bringing the game currency 100 into the game floor.

[0086] The control device 44 also checks whether the security status associated with the chip ID read by the RFID reading system 47 as security information 487 is "out of stock". If the security status is not "out of stock", the control device 44 determines that the game currency 100 was not taken out through a proper declaration and prohibits bringing it into the game floor.

[0087] The control device 44 further checks whether the player ID of player P identified by the player identification system 49 matches the player ID associated with the chip ID read by the RFID reading system 47 as owner information 484 in the database 48. If the player ID identified by the player identification system 49 does not match the player ID stored in the database 48, the control device 44 prohibits bringing the game currency 100 into the game floor.

[0088] The control device 44 determines that the game currency 100 subject to inspection is game currency 100 that was taken out after a proper declaration, and that the player ID identified by the player identification system 49 matches the player ID stored in the database 48 as the owner of the game currency 100, then permits the bringing of the game currency 100 onto the game floor. A display device (not shown) is connected to the control device 44. The control device 44 displays the result of this permission or prohibition determination on the display device.

[0089] This allows for the management of the taking in and bringing in of game currency 100 to the game floor, even when such taking in and bringing in is permitted on the condition of declaration.

[0090] As described above, in this embodiment, the security gate 41 can not only detect whether a person passing through the security gate 41 is in possession of game currency 100 using the management system 40, but it can also read the RFID component 141 of game currency 100 that is being illegally taken out or brought in, and inspect the game currency 100. Furthermore, if taking out is permitted, the RFID reading system 47 can be used to carry out the procedure for taking out, and the EM detection system 42 can be used to prevent game currency 100 from being taken out without following the proper procedure. Furthermore, if bringing in is permitted, the RFID reading system 47 can be used to carry out the procedure for bringing in, and the EM detection system 42 can be used to prevent game currency 100 from being brought in without following the proper procedure.

[0091] Furthermore, with respect to the game currency 100, an insulating first sheet-like substrate 132 is interposed between the amorphous wire 131 and the RFID component 141, and is positioned spaced apart in the thickness direction of the game currency 100. As a result, the amorphous wire 131 and the RFID component 141 do not interfere with or short-circuit each other, and it is permissible for the amorphous wire 131 and the RFID component 141 to overlap each other when viewed from the thickness direction of the game currency 100. In other words, it is possible to prevent interference or short-circuit between the amorphous wire 131 and the RFID component 141 while ensuring design flexibility for the amorphous wire 131 and the RFID component 141.

[0092] In the above embodiment, a security gate 41 was installed at the entrance to the game floor to detect game currency 100 for players entering and exiting the game floor. However, similar security gates may be installed at staff entrances for entering and exiting the security area, or at staff security gates for entering and exiting the manufacturing facility where game currency 100 is produced. In these cases, since the removal of game currency 100 is generally prohibited, the system may be configured to detect only the game currency being removed.

[0093] Furthermore, although the above embodiment describes an example in which the EM detection system 42 is installed at the security gate 41, the management system 40 may be applied to locations other than the security gate 41. For example, at an exchange counter, the management system 40 may be used to inspect the game currency 100 that a player P has handed to a staff member for exchange. In this case, the EM detection system 42 may be used to confirm whether the game currency 100 being inspected contains amorphous wire 131 as an EM wire.

[0094] Furthermore, the EM detection system 42 is not limited to being installed inside the gate; for example, the transmitting antenna 421 and receiving antenna 422 may be built into a handheld body scanner.

[0095] Furthermore, although the above embodiment describes an example in which the player identification system 49 is composed of a camera and an image recognition device, it is also possible to simply capture an image of the player's face using the camera, without identifying the player ID by image recognition. In this case, the face image may be stored in the database 48 in association with information indicating that game currency 100 has been taken out.

[0096] Furthermore, although the above embodiment describes a configuration in which the game currency 100 comprises an amorphous wire 131 as an EM wire and an RFID component 141, the configuration of the game currency 100 is not limited to the above example.

[0097] Figure 7 is a cross-sectional view of a modified example of the game currency according to an embodiment of the present invention. In this example, the EM sheet 13 is fixed to the first capsule member 11, and the RFID sheet 14 is fixed to the second capsule member 12.

[0098] The EM sheet 13 comprises a first sheet-like substrate 132, an amorphous wire 131 provided on the first sheet-like substrate 132, and a first adhesive layer 133 provided on the amorphous wire 131. The amorphous wire 131 is fixed to the first sheet-like substrate 132 by the first adhesive layer 133. The EM sheet 13 is fixed to the inner surface of the first capsule member 11 by the first adhesive layer 133 adhering to the inner surface of the first capsule member 11. As a result, the EM sheet 13 is placed in the internal space of the capsule 10.

[0099] The RFID sheet 14 comprises a second sheet-like substrate 142, an RFID component 141 provided on the second sheet-like substrate 142, and a second adhesive layer 144 provided on the RFID component 141. The RFID sheet 14 is fixed to the inner surface of the second capsule member 12 by the second adhesive layer 144. The RFID sheet 14 is fixed to the inner surface of the second capsule member 12 by the second adhesive layer 144 adhering to the inner surface of the second capsule member 12. As a result, the RFID sheet 14 is placed in the internal space of the capsule 10.

[0100] The EM sheet 13 is fixed to the inner surface of the first capsule member 11, and the RFID sheet 14 is fixed to the inner surface of the second capsule member 12. Therefore, although both the EM sheet 13 and the RFID sheet 14 are contained within the capsule 10, they do not come into contact with each other and are housed at a distance from each other inside the capsule 10.

[0101] Figure 8 is a plan view showing a modified example of an EM sheet according to an embodiment of the present invention. In the EM sheet 13', a plurality of parallel linear amorphous wires 131a are arranged on a circular first sheet-like substrate 132, and a first adhesive layer 133 is provided thereon. On the surface of the first sheet-like substrate 132 opposite to the surface on which the amorphous wires 131a are provided, a plurality of parallel linear amorphous wires 131b are provided. The amorphous wires 131a and amorphous wires 131b are arranged to intersect and are non-parallel to each other, and in this embodiment, the amorphous wires 131a and amorphous wires 131b are perpendicular to each other.

[0102] As in this example, the amorphous wires in the EM sheet 13 do not have to be endless in shape as shown in Figure 2, but may be multiple straight wires.

[0103] Furthermore, in the above embodiment, the EM sheet 13 is provided inside the capsule 10, but since the EM sheet 13 is less likely to fail than the RFID sheet 14, it may also be provided outside the capsule 10. For example, the EM sheet 13 may be placed between the first capsule member 11 and the first decal 22, or between the second capsule member 12 and the second decal 23. Also, all or part of the amorphous wire 131 may be placed between the capsule 10 and the outer peripheral portion 21. [Explanation of symbols]
