Description

  The present invention relates to an article management system, an article management method, an information processing terminal, and an information recording medium that manage the association of a plurality of articles each having unique identification information, and in particular, at least one of the plurality of articles. The present invention relates to an article management system, an article management method, an information processing terminal, and an information recording medium that are information recording media.

  The conventional anti-illegal disassembly countermeasures for the gaming table unit is one example of managing the association of a plurality of items. As a countermeasure against unauthorized disassembly of this gaming unit, a seal sticker is affixed to the joint part of the unit, and it is determined whether or not the gaming unit has been illegally disassembled by checking the trace of the sealing seal being peeled off. It has been done. In such seals, in order to make it easier to confirm the traces that have been peeled off, for example, those having a structure such that the seal seal is broken when peeled off, such as by making a cut extending in the peeling direction. It is considered.

  In recent years, a non-contact type IC label capable of writing and reading information in a non-contact state has been considered as a sealing seal as described above. The non-contact type IC label is different from a sealed label having a barcode printed on the surface, and can write information. For example, identification information such as an article ID given to an article to be sealed is written. Therefore, the reliability of the determination of illegal decomposition can be improved. In such a non-contact type IC label, when peeled off from an article, the antenna and the IC chip are broken, making it impossible to write and read information, thereby reliably detecting the peeling. The thing considered as the structure is considered (for example, refer patent document 1).

  As described above, in order to prevent unauthorized disassembly of the gaming table unit, the correspondence between the gaming table unit and the seal sticker attached thereto is used, and when the sealing seal is peeled off from the gaming table unit, that is, the game When the correspondence between the base unit and the seal sticker attached thereto is eliminated, it is determined that the gaming base unit has been illegally disassembled.

In the non-contact type information recording medium in which information can be written and read in a non-contact state like the non-contact type IC label described above, so-called RFID (Radio Frequency Identification), in recent years, it is limited to the above-described sealed label. First, it is used for inventory management of goods such as merchandise and management of physical distribution state, and is attached to an article as a label or tag, and the article is managed by writing information about the article. That is, in general article management using RFID, the association between the RFID and the article is used.
JP 2000-334154 A

  However, in what is described in Patent Document 1, after the non-contact type IC label is peeled from the article, the non-contact type IC label on which information on the article is written is newly attached as a sealed label. There is a problem that it is impossible to detect unauthorized disassembly of an article, that is, alteration of correspondence between a plurality of articles.

  In addition, when managing an article using an information recording medium, if an information recording medium on which unauthorized information is written is attached to the article, the illegally written information is used as information for managing the article. For example, there is a problem that the production area and distribution channel of food are falsified.

  The present invention has been made in view of the problems of the prior art as described above, and an article management system capable of reliably managing the association of a plurality of articles managed in association with each other.

A first information processing terminal that encrypts the identification information assigned to each of the plurality of articles together and writes the encrypted information in at least one information recording medium as encrypted information;
A second information processing terminal that reads and decrypts the encrypted information from the information recording medium.

  Further, the second information processing terminal may be configured to collate the identification information of the plurality of articles with the identification information read from the information recording medium and decrypted to output a collation result. .

  In the present invention configured as described above, for a plurality of articles managed in association with each other, the identification information assigned to each of the articles is encrypted together, and information in which information can be written among the plurality of articles It is written on the recording medium as encrypted information. After that, when confirming the correspondence of a plurality of articles, the encrypted information is read from the information recording medium, and the read encrypted information is decrypted to be encrypted together and encrypted on the information recording medium. It is confirmed whether the identification information written as the conversion information is given to each of the plurality of articles.

And an information processing terminal that reads the unique information from the information recording medium and associates the unique information with identification information given to an article associated with the information recording medium and registers the information in a database.

  In the present invention configured as described above, the identification information given to the article is associated with the article to which the identification information is given and the information recording medium on which the predetermined unique information is readable. And the unique information written in the information recording medium are associated with each other and registered in the database. The association between the article and the information recording medium is confirmed based on the association between the identification information registered in the database and the unique information.

  As described above, in the present invention, for a plurality of articles managed in association with each other, the identification information assigned to each of the articles is encrypted and information can be written among the plurality of articles. When the correspondence between a plurality of articles is confirmed, the encrypted information is read from the information recording medium, and the read encrypted information is decrypted. It is possible to reliably manage the association of a plurality of articles.

  The same effect can be obtained when the identification information given to the article and the unique information of the information recording medium associated with the article are registered in association with the database.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram showing a first embodiment of an article management system of the present invention, where (a) is a diagram showing the overall configuration, and (b) is a configuration of an information processing terminal 10 shown in (a). FIG.

  In this embodiment, as shown in FIG. 1, an unauthorized disassembly of the unit 20 in which the substrate 21 is accommodated in the case 23 is detected, and an RFID label 30 as an information recording medium is attached to the joint portion of the case 23 Then, the association between the RFID label 30 and the unit 20 is managed using the information processing terminal 10 to detect unauthorized disassembly of the unit 20.

  In the unit 20, the substrate 21 is housed in a case 23 that can be opened at the joint, and an RFID label 30 is attached as a seal seal in a state where the joint is closed. The RFID label 30 is connected to the IC chip (not shown) for writing and reading information in a non-contact state, and an antenna (not shown) for communicating with the IC chip using a predetermined frequency. Are provided on the label base material. The IC chip is written with a unique identifier (UID) that is unique to the RFID label 30 when the RFID label 30 is manufactured. In addition, the communication method via the antenna can be set as appropriate, such as an electromagnetic induction method using a 13.56 MHz frequency band or a radio wave method using a 2.45 GHz frequency band. A serial number 22 that is identification information unique to the unit 20 is displayed on the substrate 21 by silk printing or the like.

  As illustrated in FIG. 1B, the information processing terminal 10 includes an operation unit 11, an information reading unit 12, an encryption unit 13, an information writing unit 14, a decryption unit 15, and a key acquisition unit 16. , A collation unit 17 and an output unit 18.

  The operation unit 11 includes a plurality of key buttons capable of inputting numerals and alphabets, and is used to input the serial number 22 of the unit 20 displayed on the board 21.

  The information reading unit 12 can read the information written on the RFID label 30 in a non-contact state, and reads the UID and encrypted information written on the RFID label 30.

  The encryption unit 13 encrypts the serial number 22 of the unit 20 input to the operation unit 11 and the UID of the RFID label 30 read by the information reading unit 12 together.

  The information writing unit 14 can write information to the RFID label 30 in a non-contact state, and writes the information encrypted by the encryption unit 13 to the RFID label 30 as encrypted information. .

  The decryption unit 15 decrypts the encrypted information read from the RFID label 30 by the information reading unit 12.

  The key acquisition unit 16 acquires an encryption key for encryption by the encryption unit 13 and a decryption key for decrypting encryption information by the decryption unit 15. For example, it consists of a card reader, and is obtained by reading an encryption key or a decryption key written on the card.

  The collation unit 17 stores the serial number 22 of the unit 20 decrypted by the decryption unit 15 and the UID of the RFID label 30, the serial number 22 of the unit 20 input to the operation unit 11, and the information reading unit 12. The UID of the RFID label 30 read in this way is collated.

  The output unit 18 displays and outputs the collation result in the collation unit 17.

  Hereinafter, an unauthorized disassembly detection method for the unit 20, which is an article management method using the article management system configured as described above, will be described.

  First, processing when assembling the unit 20 will be described.

  FIG. 2 is a flowchart for explaining processing when the unit 20 is assembled in the article management system shown in FIG.

  The unit 20 is assembled by housing the substrate 21 in the case 23. At that time, the serial number 22 of the unit 20 displayed on the substrate 21 is input to the operation unit 11 of the information processing terminal 10 (step S1). The serial number 22 is unique identification information assigned to each unit 20 and is displayed on the substrate 21 in a visible state.

  Next, the joint portion of the case 23 in which the substrate 21 is stored is closed, the RFID label 30 is attached to the joint portion, the case 23 is sealed, and the UID of the RFID label 30 is read using the information processing terminal 10 ( Step S2). At this time, when the information processing terminal 10 is placed over the RFID label 30, the information reading unit 12 of the information processing terminal 10 reads the UID written on the RFID label 30 in a non-contact state.

  The serial number 22 of the unit 20 input to the operation unit 11 and the UID of the RFID label 30 read by the information reading unit 12 are given to the encryption unit 13, and are input to the operation unit 11 by the encryption unit 13. The serial number 22 of the unit 20 and the UID of the RFID label 30 read by the information reading unit 12 are encrypted together (step S3). The encryption in the encryption unit 13 is performed using the encryption key acquired in the key acquisition unit 16. The encryption key for encryption in the encryption unit 13 is supplied by a card, for example. An encryption key for encryption in the encryption unit 13 is written on the card, and the key acquisition unit 16 is read by the card reading unit of the key acquisition unit 16 reading the encryption key. The encryption key is obtained at The information encrypted by the encryption unit 13 is given to the information writing unit 14. The key acquisition unit 16 may acquire the encryption key when the encryption unit 13 encrypts the serial number 22 of the unit 20 and the UID of the RFID label 30 together. May be acquired in advance and stored.

  Thereafter, when the information processing terminal 10 is placed over the RFID label 30, the information writing unit 14 of the information processing terminal 10 receives the information given from the encryption unit 13 as encrypted information in a non-contact state on the RFID label 30. It is written (step S4).

  FIG. 3 is a diagram showing the configuration of the storage area of the RFID label 30 shown in FIG.

  The storage area of the RFID label 30 shown in FIG. 1 has a first storage area 31 in which the UID of the RFID label 30 is written and information can be read and the information can be written and read as shown in FIG. The encrypted information written from the information processing terminal 10 is written in the storage area 32 where information can be written and read. That is, the encryption information written on the RFID label 30 is written in a storage area different from the UID.

  In this way, when assembling the unit 20, the information processing terminal 10 is used to encrypt the serial number 22 of the unit 20 displayed on the substrate 21 and the UID of the RFID label 30 together, and RFID is used as encrypted information. Write on the label 30.

  Next, processing when confirming unauthorized disassembly of the unit 20 will be described.

  FIG. 4 is a flowchart for explaining processing when confirming unauthorized disassembly of the unit 20 in the article management system shown in FIG.

  When confirming unauthorized disassembly of the unit 20, first, when the information processing terminal 10 is placed over the RFID label 30, the information reading unit 12 of the information processing terminal 10 stores the encrypted information and UID written in the RFID label 30. Reading is performed in a non-contact state (step S11).

  The encrypted information read from the RFID label 30 by the information reading unit 12 is given to the decryption unit 15 of the information processing terminal 10, and read from the RFID label 30 by the information reading unit 12 in the decryption unit 15. The encrypted information is decrypted (step S12). The decryption of the encrypted information in the decryption unit 15 is performed using the decryption key acquired by the key acquisition unit 16, as in the encryption in the encryption unit 13. The decryption key for decryption in the decryption unit 15 is supplied by, for example, a card. In the card, the decryption key for decryption in the decryption unit 15 is written, and the decryption key written in the card is read by the card reading unit of the key acquisition unit 16, whereby the key acquisition unit 16. A decryption key is obtained. The acquisition of the decryption key in the key acquisition unit 16 may be performed when the decryption unit 15 decrypts the encrypted information read from the RFID label 30 or may be acquired in advance by the information processing terminal 10. You may remember it. The encryption key for encryption by the encryption unit 13 and the decryption key for decryption by the decryption unit 15 may use a common key by a common key encryption method, or a public key encryption method. The secret key and the public key may be used, but the latter is preferable in terms of ease of key management. That is, a secret key based on the public key cryptosystem is used as an encryption key for encryption by the encryption unit 13, and a public key based on the public key cryptosystem is used as a decryption key for decryption by the decryption unit 15. It is preferable.

  When the encrypted information read from the RFID label 30 is decrypted by the decryption unit 15, the serial number 22 of the unit 20 and the UID of the RFID label 30 are provided to the verification unit 17.

  Next, the serial number 22 of the unit 20 displayed on the substrate 21 is input to the operation unit 11 of the information processing terminal 10 (step S13).

  The serial number 22 of the unit 20 input to the operation unit 11 and the UID read from the RFID label 30 by the information reading unit 12 in step S11 are given to the verification unit 17, and the verification unit 17 decodes the decryption unit 15 Are compared with the serial number and UID given from the operation unit 11 and the information reading unit 12 (step S14).

  Thereafter, the collation result in the collation unit 17 is given to the display unit 18 and displayed (step S15). This collation result display output is obtained when, for example, the serial number and UID given from the decryption unit 15 and the serial number and UID given from the operation unit 11 and the information reading unit 12 are the same. If the serial number and UID given from the decryption unit 15 and the serial number and UID given from the operation unit 11 and the information reading unit 12 do not match, both are displayed. It is conceivable to indicate that they do not match. Further, the serial number and UID given from the decryption unit 15 and the serial number and UID given from the operation unit 11 and the information reading unit 12 may be displayed on the output unit 18.

  Here, if the unit 20 is not illegally disassembled, the same RFID label 30 should be attached to the unit 20. Therefore, when the UID written as the encryption information on the RFID label 30 is decrypted, the decrypted UID matches the UID of the RFID label 30 read from the RFID label 30 in step S11. . Similarly, when the serial number written as encryption information on the RFID label 30 is decrypted, the decrypted serial number is the serial number 22 of the unit 20 input to the operation unit 11 in step S13. Will match. On the other hand, when the unit 20 is illegally disassembled, a different RFID label 30 is attached to the unit 20. Therefore, even if the serial number 22 of the unit 20 is encrypted and written on the RFID label 30 newly attached to the unit 20 in the same manner as described above, the UID written as encryption information on the RFID label 30 Is decrypted, the decrypted UID does not match the UID of the RFID label 30 read from the RFID label 30 in step S11.

  If the board 21 in the unit 20 has not been illegally replaced, the serial numbers 22 displayed on the board 21 in the unit 20 should be the same. Therefore, when the serial number written as the encryption information on the RFID label 30 is decrypted, the decrypted serial number matches the serial number 22 of the unit 20 input to the operation unit 11 in step S13. It will be. On the other hand, when the board 21 in the unit 20 is illegally replaced, the serial number 22 displayed on the board 21 in the unit 20 is different. Therefore, even when the RFID label 30 is peeled cleanly from the unit 20 and the RFID label 30 is attached to the unit 20 again, the serial number written as encryption information on the RFID label 30 is decrypted. The decrypted serial number does not match the serial number input to the operation unit 11 in step S13.

  In this way, when the unit 20 in which the substrate 21 is stored in the case 23 is sealed with the RFID label 30, the serial number 22 of the unit 20 displayed on the substrate 21 and the RFID label are sealed using the information processing terminal 10. The encrypted information is encrypted together with the UID of 30 and written as the encrypted information on the RFID label 30, and then the information processing terminal 10 is used to read and decrypt the encrypted information written on the RFID label 30. By comparing the serial number and the UID of the RFID label 30 with the serial number of the unit 20 displayed on the substrate 21 and the UID of the RFID label 30, the RFID label 30 is peeled off from the unit 20 and the unit 20 is illegal. It can be detected whether it has been decomposed or not. That is, the association between the unit 20 and the RFID label 30 can be managed only by the information processing terminal 10 without constructing a database or a communication infrastructure for accessing the database.

(Second Embodiment)
FIG. 5 is a diagram showing a second embodiment of the article management system of the present invention, where (a) is a diagram showing the overall configuration, and (b) is a configuration of the information processing terminal 110 shown in (a). FIG.

  In the present embodiment, as shown in FIG. 5, the units 20a to 20c in which the boards 21a to 21c are accommodated in the cases 23a to 23c, respectively, and the units 20a to 20a with respect to the gaming table 40 to which the units 20a to 20c are attached The RFID labels 30a to 30c, which are information recording media, are attached to the joint portions of the cases 23a to 23c, respectively, and the gaming table 40 has identification information unique to the gaming table 40. The bar code information 41 is displayed by printing or bar code labels, and the correspondence between the RFID labels 30a to 30c, the units 20a to 20c, and the game table 40 is managed using the information processing terminal 110, whereby the unit 20a Unauthorized disassembly of -20c, and fraud of units 20a-20d with respect to the gaming table 40 To detect a place.

  Each of the units 20a to 20c is similar to the unit 20 shown in the first embodiment, in which the substrates 21a to 21c are housed in the cases 23a to 23c that can be opened at the joint, and the joint is closed. The RFID labels 30a to 30c are attached as seal seals. In addition, serial numbers 22a to 22c serving as identification information unique to the units 20a to 20c are displayed on the boards 21a to 21c.

  As shown in FIG. 5B, the information processing terminal 110 is different from the information processing terminal 10 shown in the first embodiment only in that a barcode reading unit 19 is provided.

  The barcode reading unit 19 reads the barcode information 41 displayed on the game table 40.

  Hereinafter, a method for detecting an unauthorized disassembly of the units 20a to 20c and an unauthorized replacement of the units 20a to 20d with respect to the game table 40, which is an article management method using the article management system configured as described above, will be described.

  First, a process when assembling the units 20a to 20c and the game table 40 will be described.

  FIG. 6 is a flowchart for explaining processing when assembling the units 20a to 20c and the game table 40 in the article management system shown in FIG.

  The unit 20a is assembled by housing the substrate 21a in the case 23a. At that time, the serial number 22a of the unit 20a displayed on the board 21a is input to the operation unit 11 of the information processing terminal 10 (step S101). The serial number 22a is unique identification information given to each unit 20a, and is displayed in a state of being visible on the substrate 21a.

  Next, the case is closed with the joint portion of the case 23a containing the substrate 21a, the RFID label 30a is attached to the joint portion to seal the case 23a, and the UID of the RFID label 30a is read using the information processing terminal 110 ( Step S102). At this time, if the information processing terminal 110 is held over the RFID label 30a, the information reading unit 12 of the information processing terminal 110 reads the UID written on the RFID label 30a in a non-contact state.

  Next, the barcode information 41 displayed on the gaming table 40 to which the unit 20a to which the RFID label 30a is attached is attached is read using the information processing terminal 110 (step S103). Since the barcode information 41 displayed on the gaming table 40 is a barcode representation of the serial number of the gaming table 40, the barcode reading unit 19 of the information processing terminal 110 displays the barcode information 41 on the gaming table 40. When the barcode information 41 is read, the read barcode information 41 is recognized as a serial number.

  The serial number 22a of the unit 20a input to the operation unit 11, the UID of the RFID label 30a read by the information reading unit 12, and the game read and recognized as the barcode information 41 by the barcode reading unit 19 The serial number of the table 40 is given to the encryption unit 13, and in the encryption unit 13, the serial number 22 a of the unit 20 a input to the operation unit 11 and the UID of the RFID label 30 a read by the information reading unit 12 The serial number of the gaming table 40 that is read and recognized as the barcode information 41 by the barcode reading unit 19 is encrypted together (step S104). In addition, the encryption in the encryption part 13 is performed using the encryption key acquired in the key acquisition part 16 similarly to what was shown in 1st Embodiment.

  Thereafter, when the information processing terminal 10 is placed over the RFID label 30a, the information given from the encryption unit 13 is transferred to the RFID label 30a in a non-contact state as encrypted information in the information writing unit 14 of the information processing terminal 110. It is written (step S105). Note that the encryption information is written in a storage area different from the storage area in which the UID of the RFID label 30a is written, as shown in FIG.

  The above-described processing is performed for all the units 20a to 20c.

  In this way, when assembling the units 20a to 20c and the gaming table 40, the information processing terminal 110 is used to connect the serial numbers 22a to 22c of the units 20a to 20c displayed on the boards 21a to 21c and the gaming table 40. The displayed bar code information 41 and the UIDs of the RFID labels 30a to 30c are encrypted together and written into the RFID labels 30a to 30c as encrypted information, respectively.

  Next, processing when confirming unauthorized disassembly of the units 20a to 20c and unauthorized replacement of the units 20a to 20c with respect to the gaming table 40 will be described.

  FIG. 7 is a flowchart for explaining processing when confirming unauthorized disassembly of the units 20a to 20c and unauthorized replacement of the units 20a to 20c with respect to the game table 40 in the article management system shown in FIG.

  When confirming unauthorized disassembly of the units 20a to 20c and unauthorized replacement of the units 20a to 20c with respect to the gaming table 40, first, when the information processing terminal 110 is placed over the RFID label 30a, the information reading unit 12 of the information processing terminal 110 is displayed. The encrypted information and UID written on the RFID label 30a are read in a non-contact state (step S111).

  The encrypted information read from the RFID label 30 a by the information reading unit 12 is given to the decryption unit 15 of the information processing terminal 110, and the decryption unit 15 reads from the RFID label 30 a by the information reading unit 12. The encrypted information is decrypted (step S112). The decryption of the encrypted information in the decryption unit 15 is performed using the decryption key acquired by the key acquisition unit 16 in the same manner as described in the first embodiment.

  When the decryption unit 15 decrypts the encrypted information read from the RFID label 30a, it is displayed as the serial number 22a of the unit 20a, the UID of the RFID label 30a, and the barcode information 41 of the game table 40. It becomes a serial number and is given to the collation unit 17.

  Next, the serial number 22a of the unit 20a displayed on the board 21a is input to the operation unit 11 of the information processing terminal 110 (step S113), and the bar code reading unit 19 of the information processing terminal 110 stores the game table 40. The displayed barcode information 41 is read (step S114).

  The serial number 22a of the unit 20a input to the operation unit 11, the UID read from the RFID label 30a by the information reading unit 12 in step S111, and the barcode information 41 is read by the barcode reading unit 19. The serial number of the gaming table 40 recognized in this way is given to the collating unit 17, and the collating unit 17 operates the serial number of the unit given from the decoding unit 15, the UID of the RFID label, and the serial number of the gaming table. The unit serial number, the RFID label UID, and the gaming machine serial number given from the unit 11 and the information reading unit 12 are collated (step S115).

  Then, the collation result in the collation part 17 is given to the output part 18, and is displayed and output (step S116). The collation result display output includes, for example, the serial number of the unit given from the decryption unit 15, the UID of the RFID label, and the serial number of the gaming table, and the unit given from the operation unit 11 and the information reading unit 12. If the serial number, the RFID label UID, and the game console serial number match, the fact that they match is displayed, and the serial number of the unit given by the decryption unit 15 and the RFID label If the serial number of the UID and the gaming table does not match the serial number of the unit given from the operation unit 11 and the information reading unit 12, the UID of the RFID label, and the serial number of the gaming table, the two match. It may be possible to display that it is not. Further, the serial number of the unit given from the decryption unit 15, the UID of the RFID label, and the serial number of the gaming table, the serial number of the unit given from the operation unit 11 and the information reading unit 12, the UID of the RFID label, And the serial number of the game machine may be displayed on the output unit 18.

  The above-described processing is performed for all the units 20a to 20c.

  Here, when the units 20a to 20c are not illegally disassembled, the same RFID labels 30a to 30c should be attached to the units 20a to 20c. Therefore, when the UID written as the encryption information on the RFID labels 30a to 30c is decrypted, the decrypted UID is the UID of the RFID labels 30a to 30c read from the RFID labels 30a to 30c in step S111. Will match. Similarly, when the serial number of the unit written as the encryption information on the RFID labels 30a to 30c is decrypted, the decrypted serial number is the unit 20a input to the operation unit 11 in step S113. This corresponds to the serial numbers 22a to 22c of .about.20c. On the other hand, when the units 20a to 20c are illegally disassembled, different RFID labels 30a to 30c are attached to the units 20a to 20c. Therefore, even if the serial numbers 22a to 22c of the units 20a to 20c are encrypted and written to the RFID labels 30a to 30c newly attached to the units 20a to 20c in the same manner as described above, the RFID labels 30a to 30c When the UID written as encryption information in 30c is decrypted, the decrypted UID does not match the UID of the RFID labels 30a-30c read from the RFID labels 30a-30c in step S111. .

  Moreover, when the board | substrates 21a-21c in the units 20a-20c are not improperly replaced, the serial numbers 22a-22c displayed on the boards 21a-21c in the units 20a-20c should be the same. Therefore, when the serial number of the unit written as the encryption information on the RFID labels 30a to 30c is decrypted, the decrypted serial number is stored in the unit 20a to 20c input to the operation unit 11 in step S113. This corresponds to the serial numbers 22a to 22c. On the other hand, when the boards 21a to 21c in the units 20a to 20c are illegally replaced, the serial numbers 22a to 22c displayed on the boards 21a to 21c in the units 20a to 20c are different. Therefore, even when the RFID labels 30a to 30c are cleanly peeled off from the units 20a to 20c and the RFID labels 30a to 30c are attached to the units 20a to 20c again, they are written as encrypted information on the RFID labels 30a to 30c. When the serial number thus decrypted is decrypted, the decrypted serial number does not match the serial number input to the operation unit 11 in step S113.

  In this way, when the units 20a to 20c in which the substrates 21a to 21c are accommodated in the cases 23a to 23c are sealed with the RFID labels 30a to 30c, they are displayed on the substrates 21a to 21c using the information processing terminal 110. The serial numbers 22a to 22c of the units 20a to 20c and the UIDs of the RFID labels 30a to 30c are encrypted and written into the RFID labels 30a to 30c as encrypted information, and then the information processing terminal 110 is used. The encrypted information written on the RFID labels 30a to 30c is read and decrypted. The decrypted serial number and the UID of the RFID labels 30a to 30c, the serial numbers of the units 20a to 20c displayed on the boards 21a to 21c, and Collate with UID of RFID labels 30a-30c The Rukoto, is peeled off the RFID label 30a~30c from unit 20a~20c the unit 20a~20c can detect whether it has been illegally degraded. That is, the association between the units 20a to 20c and the RFID labels 30a to 30c can be managed only by the information processing terminal 110 without constructing a database or a communication infrastructure for accessing the database.

  In addition, when the units 20a to 20c are not illegally replaced with respect to the gaming table 40, the gaming tables in which the units 20a to 20c are attached to the RFID labels 30a to 30c attached to the units 20a to 20c. The serial number of 40 should be written as encryption information together with the serial numbers of the units 20a to 20c and the UIDs of the RFID labels 30a to 30c. Therefore, when the encrypted information written in the RFID labels 30a to 30c is decrypted, the decrypted information includes the serial number of the units 20a to 20c input in step S113 and the RFID label in step S111. The UID read from 30a to 30c and the serial number read and recognized as the barcode information 41 in step S114 are included. On the other hand, when the units 20a to 20c are illegally replaced with respect to the gaming table 40, the serial numbers 22a to 22c of the units 20a to 20c and the serial number of the gaming table 40 are combined with the UIDs of the RFID labels 30a to 30c. It is encrypted and not written on the RFID labels 30a to 30c. Therefore, when the encrypted information written in the RFID labels 30a to 30c is decrypted, the decrypted information includes the serial number of the units 20a to 20c input in step S113 and the RFID label 30a in step S111. The UID read from .about.30c and the serial number read and recognized as the barcode information 41 in step S114 are not associated with each other.

  Thus, when the units 20a to 20c are attached to the gaming table 40, the information processing terminal 110 is used to display the serial numbers 22a to 22c of the units 20a to 20c displayed on the boards 21a to 21c and the bars of the gaming table 40. The serial number based on the code information 41 is encrypted together with the UIDs of the RFID labels 30 a to 30 c and written as encrypted information in the RFID labels 30 a to 30 c, and then the RFID labels 30 a to 30 c are used using the information processing terminal 110. The encrypted information written in is read and decrypted, and the decrypted information is compared with the serial numbers of the units 20a to 20c displayed on the boards 21a to 21c and the serial number based on the bar code information 41 of the game table 40 By doing so, the units 20a to 20c are illegal with respect to the game table 40. It is possible to detect whether the replaced. That is, the association between the units 20a to 20c and the game machine 40 can be managed only by the information processing terminal 110 without constructing a database or a communication infrastructure for accessing the database.

  In this embodiment, the serial numbers 22a to 22c of the units 20a to 20c displayed on the boards 21a to 21c, the serial number based on the bar code information 41 of the game table 40, and the UIDs of the RFID labels 30a to 30c are used as the units 20a to 20c. Encrypt it every 20c and write it as RFID information on the RFID labels 30a to 30c, and then use the information processing terminal 110 to read and decrypt the encrypted information written on the RFID labels 30a to 30c, By comparing the decrypted information with the serial numbers of the units 20a to 20c displayed on the boards 21a to 21c and the serial number by the bar code information 41 of the game table 40, the units 20a to 20 It is detected whether 20c is illegally replaced, but the substrate 21 All of the serial numbers 22a to 22c of the units 20a to 20c displayed on ˜21c, the serial number based on the barcode information 41 of the gaming table 40, and all of the UIDs of the RFID labels 30a to 30c are encrypted together, and encrypted information Is written in at least one of the RFID labels 30a to 30c, and this information is decrypted. The decrypted information, the serial numbers of the units 20a to 20c displayed on the boards 21a to 21c, and the bar code of the gaming table 40 are displayed. It is also possible to adopt a configuration in which it is possible to detect whether or not the units 20a to 20c have been illegally replaced with respect to the gaming table 40 by checking the serial number based on the information 41.
