  The present embodiment will be described in detail with reference to the drawings. The same or corresponding portions in the drawings have the same reference characters allotted and description thereof will not be repeated.

[A. Front side of trading card]
First, a trading card according to the present embodiment will be described. FIG. 1 is a schematic view showing an example of a trading card according to the present embodiment. FIG. 1 schematically shows the front side of three trading cards 100A, 100B, and 100C (hereinafter, also collectively referred to as “trading card 100”). In the present specification, for convenience of explanation, the surface on which the main pattern is drawn is referred to as “front surface”, and the surface opposite to “front surface” is referred to as “back surface”.

  Trading card 100 includes a plate-shaped main part on which at least one of a plurality of characters is described on at least one surface. More specifically, in the trading card 100A, the character 102A is drawn on the first surface member 101A corresponding to the front surface. In the trading card 100B, the character 102B is drawn on the first surface member 101B corresponding to the front surface. In the trading card 100C, the character 102C is drawn on the first surface member 101C corresponding to the front surface. That is, in the trading card 100 according to the present embodiment, characters 102A to 102C (hereinafter, also collectively referred to as "characters 102") are written as patterns generating the value. Character names 104A, 104B, and 104C of the characters 102A, 102B, and 102C are also drawn corresponding to the characters 102A, 102B, and 102C, respectively.

  In fact, not only the three characters illustrated in FIG. 1 but more characters are provided. Then, it is printed according to the appearance probability (generation ratio) set in advance for each of the plurality of characters, and is manufactured as the trading card 100. Here, the appearance probabilities set in advance for the respective characters are not identical to each other, and are set in consideration of individualities (characters, characteristics, positioning on a story, etc.) set for the respective characters. For example, among a plurality of characters, for a specific character, the appearance probability on the trading card 100 can be made much lower than that of other characters. As such, a trading card 100 in which a character with a low appearance probability, that is, a small number of manufactured characters is drawn, is referred to as a "premium card", "rare card", "treasure card" or the like, and is compared with other trading cards 100. May be traded at higher prices.

  For example, it is assumed that the appearance probability of the character 102C depicted on the trading card 100C among the trading cards 100A to 100C shown in FIG. 1 is low. That is, the trading card 100C is a premium card, and such a premium card is subjected to processing (gloss processing 120) which makes its surface glitter. By applying such gloss processing 120 to the surface, it is possible to give the user who holds the trading card 100 a "premium" feeling.

  Such gloss processing 120 may be realized using various methods, and in the present embodiment, the varnish is applied on the first surface member 101 and the thickness of a part of the varnish is reduced to By changing the refractive index, lame processing is realized to realize a sparkling feeling. That is, in the first surface member 101 in which the specific character 102 is written among the plurality of characters 102, partial or whole processing is applied to the resin material formed on the surface where the character 102 is written. Thus, the reflectance is made different, thereby realizing the gloss processing 120. However, as another method of such gloss processing, a reflective material such as a minute metal piece is applied on the first surface member 101 (within a range where non-contact communication is not inhibited), and light is irregularly reflected and glossed ( It is also conceivable to realize a sense of glitter or to apply so-called hologram printing on the first surface member 101. By these gloss processings, it is possible to give the user a feeling of so-called premiere (rareness) and to enhance the admirability, and it is possible to promote exchange and collection of cards among the users.

  Furthermore, in addition to the characters 102, character numbers 106A to 106C, dice patterns 108A to 108C, and junk characters 110A to 110C are drawn on the front surface of the trading card 100. Furthermore, character identification information 112A-112C are also drawn on the lower part of the front surface of the trading card 100.

  The character numbers 106A to 106C and the character specifying information 112A to 112C are information for specifying the corresponding characters 102A to 102C, respectively. Conversely, if the character numbers 106A to 106C or the numbers of the character specifying information 112A to 112C are specified, the corresponding character 102 can be uniquely specified. That is, on the front surface of trading card 100, information (character numbers 106A to 106C and character specifying information 112A to 112C) associated with character 102 is described together with character 102. That is, on the front surface of the trading card 100, identification information for specifying the character 102 is described together with the character 102. Alternatively, on the front face of the trading card 100, information for false recognition detection is represented together with the character 102. More detailed contents and applications of the character specifying information 112A to 112C will be described later.

  On the other hand, the dice patterns 108A to 108C can be used for applications such as playing a game by a plurality of persons using a plurality of trading cards 100. Similarly, the Janken patterns 110A to 110C can also be used for a purpose of performing Janken by a plurality of persons using a plurality of trading cards 100. That is, on the front surface of the trading card 100, information for playing (dice patterns 108A to 108C and junk characters 110A to 110C) is written together with the character 102.

  As information for such play, a physical strength gauge value or an attack / defense value of each character 102 may be used.

[B. Contactless communication function]
The trading card 100 according to the present embodiment has a contactless communication function. This non-contact communication function provides the trading card 100 with added value from a new viewpoint. In the present embodiment, as an example of non-contact communication, a case where communication based on a so-called near field communication (NFC) standard is performed between the trading card 100 and the NFC reader / writer will be described as an example. In this specification, contactless communication refers to a communication method for causing an electromotive force to be generated in the other device on the trading card 100 side by radio waves (for example, electromagnetic induction) from one device in the NFC reader / writer as an example. Point to. The device on the trading card 100 side can operate by the generated electromotive force (basically, it does not have a power supply, but it may be assumed that it has a power supply).

  In non-contact communication, communication becomes possible when the trading card 100 approaches the NFC reader / writer (typically, when the distance between the two is less than several centimeters or less than several tens of centimeters). In non-contact communication, radio waves continue to be sent out while communication between the two is established (while any trading card 100 approaches the NFC reader / writer). In addition, although the system which communicates by an electromagnetic wave was demonstrated as an example, it does not restrict | limit in particular especially to this, It may be light, and communication using another medium may be used, The system is not limited at all.

  The configuration for performing this noncontact communication is disposed inside the trading card 100. That is, electronic components for performing non-contact communication are included in the main part of the trading card 100.

  By mounting the non-contact communication, by holding the trading card 100 over the NFC reader / writer, the information stored in the trading card 100 can be read out, and the information stored in the trading card 100 is updated ((1) Alternatively, new information can be written).

  More specifically, a storage unit for storing data associated with the character 102 described in the main unit inside the trading card 100, and a storage unit for receiving data received from an external device by non-contact communication And a circuit for writing. As one implementation example, an electronic component including a storage unit and a writing circuit is disposed in the inside of the trading card 100 in the form of an RFID (Radio Frequency IDentification) inlay. Hereinafter, the configuration of the electronic component will be described in association with the back surface of the trading card 100.

[C. Back side of trading card]
FIG. 2 is a schematic view showing a configuration example of the back surface of trading card 100 according to the present embodiment. Referring to FIG. 2, on the second surface member 103 corresponding to the back surface of the trading card 100, a presentation pattern 130 indicating the position of an antenna used for non-contact communication is drawn. That is, on the surface (back surface) different from the surface (front surface) on which the character 102 is written, a mark (presentation pattern 130) indicating the position of the antenna is written at the position where the antenna is arranged. It is done. The presence of the mark enables the user to understand at a glance which part of the trading card 100 should be brought close to the NFC reader / writer in order to perform contactless communication, and contactless communication using the card The convenience when doing Also, by putting the mark on a surface different from the surface on which the character 102 is written, it becomes possible to confirm the position of the antenna without impairing the design of the drawn character (thus, preference Also improves the sex.).

  FIG. 2 shows an example in which the design of the back surface is made common without depending on the character 102 drawn on the front surface of the trading card 100, but the present invention is not limited to this. That is, different patterns or designs may be applied to the back surface, for example, a pattern or design associated with the character 102 drawn on the front surface may be applied.

  More specifically, the presentation pattern 130 consists of an aluminum layer 132 and a printing layer 134 formed on the aluminum layer 132.

  FIG. 3 is a schematic view showing a cross-sectional view of the trading card 100 corresponding to the line AA shown in FIG. The thickness of each layer shown in FIG. 3 does not necessarily correspond to the actual value, and is drawn to be thicker or thinner than the actual thickness for the convenience of the description. As an example, the thickness of the entire trading card 100 is designed to be about 0.3 mm to 1.0 mm.

  Referring to FIG. 3, the trading card 100 includes, as main parts, a first surface member 101 corresponding to the front surface and a second surface member 103 corresponding to the back surface. That is, the main part of the trading card 100 substantially corresponds to the first surface member 101 and the second surface member 103. The first surface member 101 and the second surface member 103 can use printing paper in order to apply various designs to their surfaces. That is, at least a part of the main part of the trading card 100 is formed of a paper layer.

  An RFID inlay 140 is disposed between the first surface member 101 and the second surface member 103. The RFID inlay 140 is an electronic component integrated with a circuit and an antenna necessary for contactless communication. More specifically, the RFID inlay 140 mainly includes a buffer film 142, an antenna 144, and an IC chip 146.

  As the buffer film 142, a resin according to the load capacity is used, but for example, a PET (polyethylene terephthalate) resin may be used. The antenna 144 transmits and receives a wireless signal related to non-contact communication. More specifically, the antenna 144 is made of a conductive wire wound many times along the surface of the buffer film 142, and is electrically connected to the IC chip 146. As described later, the IC chip 146 mainly includes a transmission / reception circuit that receives radio waves (including a command) via the antenna 144 and transmits radio waves (including a command response) from the antenna 144, and a control circuit. Including.

  A presentation pattern 130 is provided on the back surface in association with the position where the antenna 144 is disposed. Although a substantially square presentation pattern 130 is shown in FIG. 2, an arbitrary shape can be adopted. For example, the presentation pattern 130 may be configured in a circular, pentagonal, hexagonal, octagonal, or other shape. As described above, the presentation pattern 130 includes the aluminum layer 132 and the printing layer 134 formed on the aluminum layer 132. The aluminum layer 132 is typically formed by aluminum deposition, and the printing layer 134 is formed by printing (application of ink) after the aluminum deposition. As the mark drawn on the print layer 134, a logo mark, which is a mark that symbolizes the trading card 100 or a person who manufactures or sells the trading card 100, can also be used.

  Thus, the mark indicating the position of the antenna 144 is a part of the aluminum layer 132 of a predetermined shape formed on a surface (back surface) different from the surface (front surface) on which the character 102 is written, And the logo formed on the aluminum layer 132 (a part of the mark drawn on the printing layer 134).

  Although FIG. 3 shows a configuration example in which the IC chip 146 is disposed on the front side and the antenna 144 is disposed on the back side, the positional relationship between the IC chip 146 and the antenna 144 is reversed. May be (Ie, the IC chip 146, the antenna 144, and the buffer film 142 may be arranged in this order as viewed from the back surface side. In this case, the buffer film 142 is placed on the inner surface of the front surface. Will be deployed). However, as described later, in the usage form where communication is performed with the NFC reader / writer while showing the character 102 drawn on the front surface of the trading card 100, the intensity of the radio wave incident on the antenna 144 is secured. In order to do so, the antenna 144 may be closer to the back surface.

  Further, FIG. 3 shows a configuration example in which the IC chip 146 is disposed in association with the substantially central position of the antenna 144, but the positional relationship between the antenna 144 and the IC chip 146 in the plane can be appropriately designed. . That is, the IC chip 146 may be disposed eccentrically to the antenna 144.

  Furthermore, the RFID inlay 140 itself can be placed at any position. FIG. 4 is a schematic view showing an arrangement example of the RFID inlay 140 in the trading card 100 according to the present embodiment.

  FIG. 4A shows an example in which the RFID inlay 140 including the antenna 144 and the IC chip 146 is disposed substantially at the center of the trading card 100. According to the arrangement example shown in FIG. 4A, since the RFID inlay 140 including the antenna 144 is arranged substantially at the center of the trading card 100, it is possible for the user to be confused when holding the trading card 100 over the NFC reader / writer. Can be reduced.

  FIG. 4B shows an example in which the RFID inlay 140 including the antenna 144 and the IC chip 146 is located at the center in the left-right direction of the trading card 100 and on the end side (outside) in the up-down direction. As shown in FIG. 4 (B), the RFID inlay 140 is shifted from the center of the trading card 100 to form the RFID inlay 140 when the trading card 100 is bent (or bent). The displacement (or stress) can be further reduced. Therefore, the possibility that the RFID inlay 140 is broken due to external force accompanying deformation of the trading card 100 can be reduced.

  FIG. 4C shows an example in which the RFID inlay 140 including the antenna 144 and the IC chip 146 is disposed on the end side (outside) in both the horizontal direction and the vertical direction of the trading card 100. In the arrangement example shown in FIG. 4C, compared to the arrangement example shown in FIG. 4B, it is possible to reduce the magnitude of the external force generated in the RFID inlay 140 as the trading card 100 is deformed. Therefore, the possibility that the RFID inlay 140 is broken by external force can be further reduced.

  As shown in FIG. 4 (B) and FIG. 4 (C), from the viewpoint of reducing the possibility of breakage of the RFID inlay 140 (the antenna 144 and the IC chip 146), it deviates from the central portion of the main surface of the trading card 100. It may be placed in a different position. For example, the entire antenna 144 may be above or below the longitudinal centerline of the trading card 100.

[D. Example of usage form]
Next, an example of usage of trading card 100 according to the present embodiment will be described. FIG. 5 is a schematic diagram showing an example of usage of trading card 100 according to the present embodiment.

  FIG. 5 shows an example in which the portable game apparatus 1 is used as an NFC reader / writer. The portable game apparatus 1 adopts a foldable configuration having two screens, and it is assumed that an antenna for transmitting and receiving radio waves used for non-contact communication is built in the lower display 2. Typically, the user holds the portable game apparatus 1 with one hand while holding the trading card 100 over the lower display 2 with the other hand, the trading card 100 and the portable game apparatus 1. An exchange of information takes place between Using the data read from the trading card 100, the game is progressed in the portable game device 1, or according to the game progress in the portable game device 1, or the result is written to the trading card 100 can do.

  The data read from the trading card 100 may be used in any way, and the data to be written to the trading card 100 may be obtained or generated. That is, data exchanged with the trading card 100 can be associated with any information processing executed by the portable game device 1.

  Although FIG. 5 exemplifies the configuration in which the portable game apparatus 1 is used as an NFC reader / writer for convenience of explanation, any device can be used as a trading card 100 if it is a device capable of non-contact communication (NFC). Data may be exchanged between the

[E. Circuit configuration]
Next, the circuit configuration of the RFID inlay 140 included in the main part (the first surface member 101 and the second surface member 103) of the trading card 100 will be described.

  FIG. 6 is a schematic view showing a circuit configuration of the RFID inlay 140 included in the trading card 100 according to the present embodiment. Referring to FIG. 6, RFID inlay 140, which is an electronic component, includes an antenna 144 for transmitting and receiving a wireless signal related to non-contact communication, and an IC chip 146 electrically connected to antenna 144. The IC chip 146 includes a transmission / reception circuit 147 and a control circuit 148 electrically connected to the transmission / reception circuit 147. Control circuit 148 includes a storage unit 149. The storage unit 149 stores data associated with the character 102 described in the main part of the trading card 100. Control circuit 148 includes a circuit that writes data received from an external device by non-contact communication to storage unit 149.

  FIG. 7 is a schematic view showing an example of the data structure of the storage unit 149 incorporated in the control circuit 148 shown in FIG. Referring to FIG. 7, storage unit 149 includes a shared area 149A and a writable area 149B. The shared area 149A is a storage area in which the writing of further data is restricted, and the writable area 149B is a storage area in which the restriction is not provided. For example, the shared area 149A is an area (read only area) only for reading data, and a restriction is set such that data writing (data overwrite) can not be performed, and the restriction is set in the writable area 149B. It is not set and data can be written. However, even in the writable area, before writing data, a simple check such as a check on the suitability of the format of the data to be written or a check on the writing order of the data group to be written is correct. Can be

  The shared area 149A includes a character ID and a series ID, which are data associated with the character 102. That is, the character ID is stored in the shared area 149A.

  The character ID is identification information for identifying the character 102 drawn on each trading card 100. The character ID is set so as to uniquely identify the character 102 in a specific application (for example, a game application or the like). In this case, each application includes the correspondence between the character ID and the character 102. When any character ID is read from the trading card 100 during execution of any application, information (character image or the like) of the character corresponding to the character ID is determined with reference to the correspondence held in advance. It should be noted that even if the same character is drawn on the card, different character IDs are set for each card due to differences in pose, appearance, etc., and different corresponding character images etc. It is also possible to decide.

  Alternatively, the setting may be made so that the character 102 can be uniquely identified among a plurality of applications. In this case, the correspondence relationship between the character ID and the character 102 may be commonly held among a plurality of applications. Alternatively, when the network can be used, a server that can be used commonly by each application is accessed to determine information (such as a character image) of the character corresponding to the character ID read from the trading card 100.

  The series ID is an example of identification information indicating an application that can use the character 102 depicted on each trading card 100 or a series of available applications. More specifically, the series ID is identification information that identifies one or more applications for which the character 102 depicted on each trading card 100 can be used. If there is only one application available, the series ID will essentially identify one application. On the other hand, if there are multiple applications available, the series ID will identify a series of available applications.

  The character ID and the series ID are protected or encrypted so that writing or updating can not be performed with a normal command from the NFC reader / writer (in the present embodiment, the portable game apparatus 1). That is, writing or updating of further data is restricted so that the correspondence with the character 102 drawn on each trading card 100 is maintained.

  On the other hand, the writable area 149B is an area where an application using the character 102 drawn on the trading card 100 can write or update. Data and the like generated by processing by the application are appropriately written in the writable area 149B. If multiple applications write data to writable area 149B, a problem may occur due to mixing of data. Therefore, only a single application specified by the user through a specific operation can be written to You may enable access to 149B. Applications accessible to the writable area 149B can also be changed later.

  Further, the control circuit 148 is uniquely assigned to the RFID inlay (or the IC chip 146). Referring again to FIG. 6, control circuit 148 stores serial number 148a therein, and responds to a command from an NFC reader / writer or the like to respond to the value of stored serial number 148a. That is, the RFID inlay 140, which is an electronic component, includes identification information unique to the RFID inlay 140. Such identification information can be used for various authentication processes.

[F. Trading Card Set and Function to Prevent Incorrect Reading]
Next, a sales form of trading card 100 according to the present embodiment as described above will be described. Usually, a trading card is sold in the state where the picture drawn on the surface can not be seen, putting one or more sheets into one package. In general, trading cards are valued by their design, so that a buyer can look forward to having a trading card with what kind of design drawn on the package he / she purchased.

  When selling trading cards 100 according to the present embodiment, a plurality of trading cards 100 are selected such that there is no duplication of characters 102 in the same package. That is, the trading card set (the state at the point of sale) according to the present embodiment includes a plurality of trading cards 100, and each of the plurality of trading cards 100 has at least two characters 102 different from each other. There is.

  As described above, the trading card 100 according to the present embodiment has the contactless communication function implemented, and even if it is sold in a package, the information stored in any NFC reader / writer If it can be read out, the character of the trading card 100 contained in it can be identified. In addition, if the information is read out in a state of being put in a package and sold, games etc. can be made using the information on the application without purchasing a card. In order to prevent such unauthorized reading, access from the outside of the package to the trading card 100 inside the package may be blocked.

  That is, the trading card set according to the present embodiment includes at least one trading card 100 and a package (sack portion) for storing the at least one trading card 100 therein, and the package (sack portion) A shield function is added to prevent external electromagnetic waves from reaching the trading card 100 stored inside the package (bag). That is, the shielding function reduces the electromagnetic waves involved in the non-contact communication, and prevents the non-contact communication by the electronic components contained in the trading card 100 housed in the package (bag portion). Hereinafter, some implementation examples of such a shield function are described.

(F1: first implementation example)
FIG. 8 is a schematic diagram showing a first implementation example of the function of preventing unauthorized reading of the trading card 100 according to the present embodiment. Referring to FIG. 8, as a first implementation example of the shield function, a card having conductivity is mixed between a plurality of trading cards 100. That is, a trading card set in which a plurality of trading cards 100 (three trading cards 100A to 100C in the example shown in FIG. 8) are enclosed in a package 200 is shown. The package 200 is sealed in a pillow shape.

  An aluminum card 210 is disposed between the three trading cards 100A and 100B or between 100B and 100C. That is, the trading cards 100A to 100C and the set 220 of the aluminum cards 210 may be sold as a trading card set in a state of being enclosed in the package 200. That is, as a member exhibiting a shielding function, a plate-like member (aluminum) provided side by side along the vertical direction of the main surface of at least one trading card 100 and provided with a conductive member (for example, aluminum) on its surface Card 210).

  The aluminum card 210 is formed, for example, by forming an aluminum layer on both surfaces of a printing sheet by a method such as aluminum deposition. An aluminum layer may be formed over the entire surface of at least one of the aluminum cards 210. However, any electrode pattern may be formed on the surface. For example, by using a spiral electrode pattern or the like, an eddy current can be generated in the electrode pattern, and electromagnetic waves can be more efficiently prevented from reaching the trading card 100. Further, the entire surface of the card need not be covered with the aluminum layer, and may be configured to cover only a part of the card, such as only around the antenna portion. Although aluminum may be used from the viewpoint of manufacturing cost and the like, the surface layer may be formed using a material having an arbitrary conductivity (for example, an arbitrary metal). Thus, as a member that exhibits a shielding function, a card (aluminum card 210) that is housed inside the package (bag) together with the trading card 100 and includes a metal layer is included.

  For example, one aluminum card 210 may be arranged for every three trading cards 100. In addition, in the case of sealing more trading cards 100 in the package 200, it is also conceivable to mix two or more aluminum cards 210 for each predetermined number.

  The surface of the aluminum card 210 can be used as a space for a description of the trading card 100 or a space for a description or an advertisement for the trading card 100 or a product related thereto.

  In order to exert the shield function in the set 220 (the trading cards 100A to 100C and the aluminum card 210) shown in FIG. 8, it is necessary to keep the cards in close contact with each other. As such, the inner cross-sectional shape of the package 200 may be designed such that the gap is smaller than the outer cross-sectional shape of the set 220.

(F2: second implementation example)
FIG. 9 is a schematic view showing a second implementation example of the function of preventing unauthorized reading of the trading card 100 according to the present embodiment. FIG. 10 is a schematic cross-sectional view of the package shown in FIG.

  Referring to FIGS. 9 and 10, on the entire inner surface of package 250, a conductive member layer 252 for exhibiting a shielding function is formed. On the outer side of the conductive member layer 252, for example, a layer of resin or the like is formed. In addition, in order to exhibit a shielding function, the conductive member layer 252 is formed to have a predetermined thickness. That is, the package 250 (bag portion) according to the present embodiment includes a metal layer provided on the inner surface thereof as a shield means.

  In the second mounting example shown in FIGS. 9 and 10, there is no need to bring the plurality of trading cards 100 into close contact with each other, so the inner cross sectional shape of the package 250 is slightly more relaxed than the outer cross sectional shape of the plurality of trading cards 100. It may be formed with

(F3: third implementation example)
FIG. 11 is a schematic diagram showing a third implementation example of the function of preventing unauthorized reading of the trading card 100 according to the present embodiment. Referring to FIG. 3, three trading cards 100 </ b> A to 100 </ b> C may be enclosed in conductive mesh bag 270 in a set state. In this case, the three trading cards 100A to 100C enclosed in the reticulated bag portion 270 are further enclosed in the non-translucent outer bag.

(F4: fourth implementation example)
A sealed metal film may be attached directly to the entire trading card 100 or around the antenna 144.

[G. Manufacturing process]
Next, a manufacturing process of trading card 100 according to the present embodiment will be described.

  FIG. 12 is a schematic view showing an example of a manufacturing process of trading card 100 according to the present embodiment. Referring to FIG. 12, the manufacturing process of trading card 100 includes a printing process, a cutting process, an image recognition process, and an information writing process.

  In the printing process, typically, a plurality of printing patterns randomly selected according to a plurality of predetermined appearance probabilities are printed on the printing paper. Each printing pattern corresponds to the design of the front or back surface of the trading card 100. That is, a plurality of trading cards 100 are randomly imposed. Exclusive processing is performed so that the same trading card 100 is not imposed on the same printing sheet. A plurality of RFID inlays 140 are regularly arranged in advance in association with the position to be imposed. However, a set of printed sheets respectively corresponding to the front surface and the back surface may be prepared, the RFID inlays 140 may be regularly arranged between them, and then the two may be pasted together.

  Subsequently, the printing paper is cut into a predetermined size, and the trading card 100 is generated. In this state, since no data is written in the RFID inlays 140 contained in each trading card 100, the character identification information 112 (see FIG. 1) printed on the front surface is optically read. Then, the information associated with the character 102 drawn on each trading card 100 is written.

  Specifically, in the image recognition step, the character identification information 112 (see FIG. 1) present on the front surface of the trading card 100 after cutting is read, and its value (character or numerical value) is recognized. . Then, based on the recognition information, the corresponding identification information (character ID and series ID) is written to the shared area 149A (see FIG. 7) of the storage unit 149 (information writing step). After this information writing process, the trading card 100 according to the present embodiment is completed.

  The character identification information 112 (see FIG. 1) used in the image recognition process is added to identification information for identifying the character 102 drawn on the front face of each trading card 100 to prevent false recognition. Additional information may be included. That is, the character specifying information 112 which is a part of the information associated with the character 102 may include identification information for specifying the character 102 and information for false recognition detection. By including such information for false recognition detection, it is possible to prevent that information different from the information corresponding to the drawn character 102 is erroneously written to the trading card 100.
