Technical Field

The present invention relates to a token with an RFID tag incorporated therein and a method for manufacturing the token.

Background

Conventionally, a token with an RFID tag incorporated therein as a security member is known. The RFID tag stores security information such as authentication information and identification information, and stores various information related to the token in association with the security information in a database. If the RFID tag is removed from the token for an improper purpose, and decryption, copying, and the like are performed, security is adversely affected.

Fig. 10 is a sectional view showing an example of a structure of a conventional token. In the example of fig. 10, a concave portion 101 is formed in the center portion of the medal 100, and a decal member 103 is affixed in the concave portion. An adhesive RFID tag 104 as a security member is attached to the back surface of the decal member 103 (for example, U.S. patent specification No. 6659875). In the conventional token 100, the security member can be incorporated in the token with such a configuration.

Also, a token incorporating a coil-type RFID tag as a security member is known. The coil-type RFID tag is formed, for example, by molding a resin body member so as to enclose the coil-type RFID tag, thereby forming a token incorporating the RFID tag.

Disclosure of Invention

Problems to be solved by the invention

However, in the conventional token having the RFID tag of the stick type built therein, the RFID tag can be taken out only by peeling off the decal member. Therefore, the RFID tag can be easily taken out without being damaged, and the risk of being counterfeited is relatively high. Further, in the conventional game chip incorporating the attachment type RFID tag, since the RFID tag is located close to the surface of the game chip, the RFID tag receives an external force via the decal member, and the risk of breakage during use is relatively high.

Further, in the conventional game chip incorporating the adhesive RFID tag, since the RFID tag is located close to the surface of the game chip, when a plurality of game chips are stacked and a plurality of RFID tags are simultaneously read, the distance between the plurality of RFID tags becomes uneven, and the reading of the RFID tag becomes unstable.

On the other hand, since the coil-shaped RFID tag can be incorporated in the center of the coin in the thickness direction, it can be read relatively stably even when stacked, and since the RFID tag can be covered with the molded resin, the risk of forgery due to removal of the RFID tag and the risk of damage to the RFID tag due to use are relatively small. However, since the coil-type RFID tag-containing game chip is directly covered with the molding resin, the RFID tag may be damaged during the manufacturing process.

The present invention is directed to solving at least some of the problems set forth above.

Means for solving the problems

A token according to an aspect of the present invention incorporates an adhesive RFID tag, and includes: an inner packaging member having a predetermined shape for packaging the RFID tag; a main body member that is injection molded so as to enclose the inner package member enclosing the RFID tag; and a decal member that displays the type or amount of the game piece; the inner cover member includes a first part and a second part, at least the first part or the second part has a flat surface capable of being in close contact with the adhesive RFID tag, and the medal is configured such that the inner cover member is formed by combining the first part and the second part, and the adhesive RFID tag is covered with the first part and the second part.

According to this configuration, the adhesive RFID tag is incorporated in the token in a state of being wrapped in the inner wrapping member. Therefore, the RFID tag is not easily taken out, and the RFID tag is not broken by use. Further, since the body member is injection-molded around the RFID tag in a state where the RFID tag is wrapped in the inner wrapping member, the possibility that the RFID tag is damaged by the manufacturing process can be reduced.

The entire surface of the inner wrap member may be covered by the injection molded body member and the decal member. According to this configuration, since the inner cover member in which the RFID tag is wrapped is not exposed to the surface of the token, the security can be ensured.

The inner wrap member enclosing the RFID tag may be located at a central portion of the game chip, and the decal member may be located at a peripheral portion in a thickness direction of the game chip. According to this structure, the RFID tag can be located inside the decal.

The RFID tag may store information related to a game chip, which may be read in a state of stacking a plurality of game chips. According to this configuration, the RFID tags of the medals stacked on the game table or the medal tray can be read at the same time.

The RFID tag may be included at a position within ± 25% of the thickness of the medal from the center in the thickness direction of the medal. According to this configuration, even in the case where a plurality of medals are stacked, the distance variation between a plurality of adjacent RFID tags can be reduced, and the RFID tags can be stably read.

The first portion and the second portion may be combined to form a closed space for housing the RFID tag. According to this configuration, the adhesive RFID tag is incorporated in the token in a state of being sealed in the sealed space formed by the inner cover member.

The enclosed space for receiving the RFID tag may be formed by pressing the first portion into the second portion. According to this configuration, the RFID tag can be easily and reliably enclosed in the inner cover member when the medal is manufactured.

The closed space for housing the RFID tag may be configured by locking the first portion and the second portion to each other. According to this configuration, the RFID tag can be easily and reliably enclosed in the inner cover member when the medal is manufactured.

The closed space for receiving the RFID tag may be constituted by adhering the first portion and the second portion to each other. According to this configuration, even when the medal is manufactured, the RFID tag can be easily and reliably enclosed in the inner covering member.

The inner bag member in which the RFID tag is enclosed may be constituted by sandwiching the RFID tag between the first portion and the second portion. According to this configuration, the RFID tag can be easily contained in the inner cover member when the medal is manufactured.

The inner wrapping member that wraps the RFID tag is configured by sandwiching the RFID tag between the first portion and the second portion and bonding the first portion and the second portion. According to this configuration, the RFID tag can be reliably wrapped in the inner covering member when the medal is manufactured.

The first portion and the second portion may be joined. According to this configuration, the operation of wrapping the RFID tag in the inner wrapping member is facilitated.

The first portion and the second portion may be joined in a hinge shape. According to this configuration, the operation of wrapping the RFID tag in the inner wrapping member is facilitated.

The RFID tag may have a diameter greater than a diameter of the decal member. In the conventional RFID tag attached to the back surface of the decal, the RFID tag cannot be larger than the decal, but the size of the RFID tag can be made sufficiently large by adopting a structure in which the main body member is injection-molded so as to cover the inner wrapping member in which the RFID tag is wrapped.

The inner pack member may have a specific gravity greater than that of the body member. With this configuration, the medal can be set to any weight.

The inner pack member may have a specific gravity smaller than that of the body member. With this configuration, the medal can be set to any weight.

The inner pack member may be formed in the predetermined shape by injection molding. According to this structure, the inner pack member can be easily manufactured.

A method for manufacturing a token according to an aspect of the present invention includes: a first step of attaching an attachment type RFID tag to a first part in which a flat surface for closely attaching the attachment type RFID tag is formed in advance; a second step of covering a second portion of the first portion to which the RFID tag is closely attached, and forming an inner package member that encloses the RFID tag; and a third step of forming a main body including the inner pack member including the RFID tag by insert-molding the inner pack member including the RFID tag as an insert portion.

According to this configuration, it is possible to manufacture a token in which the adhesive RFID tag is contained in the inner cover member.

A token according to an aspect of the present invention incorporates an RFID tag, and includes: an inner packaging member having a predetermined shape for packaging the RFID tag; a main body member that is injection molded so as to enclose the inner package member enclosing the RFID tag; and a decal member that displays the type or amount of the game piece; the medal has a structure in which the inner pack member is formed by combining a first portion and a second portion, the RFID tag is covered with the first portion and the second portion, and the inner pack member is covered with the body member and the decal member with the inner pack member as a center.

According to this configuration, the RFID tag is incorporated in the token in a state of being wrapped in the inner wrapping member. Therefore, the RFID tag is not easy to take out, and the RFID tag is not damaged due to use. Further, since the body member is injection-molded around the RFID tag in a state where the RFID tag is wrapped in the inner wrapping member, the possibility that the RFID tag is damaged by the manufacturing process can be reduced.

Detailed Description

Hereinafter, a token according to the present invention will be described in detail with reference to the drawings. In the following description, a disk-shaped token is described as a token according to an embodiment of the present invention, but the present invention is not limited to the following embodiment. For example, the medal may have a rectangular plate shape or other shapes. Furthermore, the game pieces may be game cards. Further, the components of the following embodiments include those which are easily conceivable by those skilled in the art or substantially the same.

Fig. 1 is a perspective view of a token according to a first embodiment of the present invention. As shown in fig. 1, the token 10 has a disk shape as a whole. Hereinafter, the two flat surfaces of the disk shape are referred to as surfaces. The medal 10 includes: a body member 11 having an outer surface which becomes at least a part of the medal 10; and a decal member 13 located at the central portion of both surfaces of the game chip 10. The body member 11 is formed in a doughnut shape on the surface of the token 10, the decal member 13 is disposed inside the body member 11, and the body member 11 is positioned around the decal member 13.

The side surface of the medal 10 is constituted by a body member 11. The side surface is divided into three layers in the thickness direction by color. The two layers on both surface sides (outer sides) are the same color, and the color of the intermediate layer is different from the two layers on the surface sides. As a result, the medal 10 has a striped pattern in which the color changes in the thickness direction on the side surface.

The medals 10 are arranged at predetermined angular intervals in a pattern extending from the edge of one surface of the body member 11 to the edge of the other surface thereof through the side surface. As a result, a stripe pattern in which colors change in the circumferential direction is formed on the side surface, and a stripe pattern in which colors change at predetermined intervals in the circumferential direction is also formed on the edge of the surface. The above-described pattern on the peripheral edge and side surface of the main body member 11 and the color constituting the pattern indicate at least one of the type and amount (value) of the medal 10.

Fig. 2 is a sectional view of a token according to the first embodiment of the present invention, and fig. 3 is an exploded sectional view of the token according to the first embodiment of the present invention. As shown in fig. 2 and 3, the game chip 10 includes a body member 11, an inner cover member 12, a decal member 13, and an RFID tag 14.

The RFID tag 14 is enclosed in the inner package member 12. The body member 11 is formed to cover the edge portions of both surfaces of the inner cover member 12 over the entire circumference. A decal member 13 is disposed at a step between the body member 11 and the inner pack member 12. As a result, body member 11 is substantially flush with decal member 13 on the surface.

The inner package member 12 includes a first portion 121 and a second portion 122. The first portion 121 and the second portion 122 are each formed by injection molding a resin. The first portion 121 has a peripheral wall 121a at a peripheral edge portion of a disk shape, and is substantially shaped like a tray. The inner bottom portion 121b inside the peripheral wall 121a is a flat surface so as to be closely attached to the attachment type RFID tag 14. The second portion has a disk shape and has a flange 122a at its peripheral edge.

The specific gravity of the inner member 12 may be higher than that of the main body member 11, or may be lower than that of the main body member 11. The weight of the medal 10 is determined by appropriately setting the specific gravity of the inner pack member 12. That is, if the size (diameter and thickness) of the medal 10 is determined and the material of the body member 11 is determined, the specific gravity of the inner pack member 12 can be determined so as to obtain the required weight of the medal 10. Alternatively, the specific gravity of the body member 11 may be determined to obtain the desired weight of the medal 10 after the size of the medal 10 is determined and the material of the inner pack member 12 is determined. The specific gravities of the inner cover member 12 and the body member 11 can be adjusted by mixing metal powder into the materials.

The RFID tag 14 is an adhesive type RFID tag and is adhered to the planar inner bottom portion 121b of the first part 121. The first part 121 and the second part 122 are combined with each other by pressing the second part 122 into the peripheral wall of the first part 121 and abutting the flange 122a of the second part 122 against the upper part of the peripheral wall 121a of the first part 121. At this time, the first portion 121 and the second portion 122 form a closed space 12a for accommodating the RFID tag 14 therebetween. Note that the contact portion between the first portion 121 and the second portion 122 is bonded by an adhesive.

The RFID tag 14 is a passive type RFID tag, and obtains electric power by being excited by electromagnetic waves emitted from an RFID reader. The RFID reader reads information stored in the RFID tag 14 using electromagnetic waves. The RFID reader is capable of simultaneously reading a plurality of RFID tags 14 respectively built in a plurality of stacked gaming chips 10 together.

The RFID tag 14 stores information relating to the gaming chip 10. The information includes at least any one of identification Information (ID) for uniquely identifying the token 10, the kind of the token 10, and the amount, and further, may include information indicating the history of the token 10 and the holder.

As described above, the inner packing member 12 is a capsule container having a hollow disk shape, and the RFID tag 14 is packed in the sealed space 12 a. Further, the RFID tag 14 is covered with the first portion 121 and the second portion 122 in such a manner as to be sandwiched between the first portion 121 and the second portion 122. Further, the RFID tag 14 is closely attached to the planar inner bottom portion 121b of the first portion 121.

The main body member 11 is formed by injection molding so as to cover the entire periphery of the peripheral edge and the side surface of the inner package member 12 in which the RFID tag 14 is incorporated. Thereby, the body member 11 is formed into a doughnut-shaped hollow circular shape, and the inner cover member 12 is covered inside thereof. That is, the main body member 11 is injection molded so as to enclose the inner pack member 12.

When the main body member 11 is formed around the inner cover member 12, a portion other than the peripheral edge portion of the inner cover member 12 is exposed on the inner side of the surface of the main body member 11. A step is formed between the exposed portion 12b of the inner cover member 12 and the annular surface of the main body member 11, and a circular recess 12c is formed by the step.

Decal member 13 has substantially the same shape as recess 12c, is disposed in recess 12c, and is adhered to exposed portion 12 b. As a result, the surface of the decal member 13 is at substantially the same height as the annular surface of the body member 11.

The surface of the applique member 13 displays at least either the type or the amount of the medal 10. The decal member 13 is coated with an adhesive on the back surface thereof, and is attached to the exposed portion 12b of the inner pack member 12 with the adhesive.

As described above, the entire surface of the inner cover member 12 is covered with the body member 11 and the decal member 13, and the medal 10 does not have any exposed portion of the inner cover member 12. Therefore, the inner pack member 12 is less likely to be damaged during use.

The RFID tag 14 is coated with an adhesive on the back surface thereof, and is attached to the inner bottom portion 121b of the first portion 121 of the inner pack member 12 with the adhesive. Further, since the height of the sealed space formed inside the inner cover member 12 is larger than the thickness of the RFID tag 14, the RFID tag 14 does not contact the inner side surface of the second part 122 in a state where the RFID tag 14 is attached to the inner bottom portion 121b of the first part.

On the other hand, the height of the sealed space formed inside the inner cover member 12 is slightly higher than the RFID tag 14. Therefore, if the inner cover member 12 is improperly removed from the main body member 11 or the inner cover member 12 is broken to remove the RFID tag 14, the RFID tag 14 is likely to be damaged. As described above, in the token 10 of the present embodiment, it is difficult to take out the RFID tag 14 without breaking it.

As described above, in the token 10 of the present embodiment, the inner cover 12 that covers the RFID tag 14 is located at the center in the thickness direction of the token 10, and the decal 13 is located at the peripheral edge in the thickness direction of the token 10. Therefore, the RFID tag 14 is located at the approximate center in the thickness direction of the medal 10. Specifically, the RFID tag 14 is disposed at a position within ± 25% of the center of the medal 10 in the thickness direction. Therefore, even if a plurality of game pieces 10 are stacked in an arbitrary orientation, the distances between adjacent RFID tags 14 are not deviated or are slightly deviated, and the RFID reader can stably read using electromagnetic waves.

In the token 10 of the present embodiment, the size of the RFID tag 14 is not limited by the size of the decal member 13, and the RFID tag 14 can be secured to have a size necessary for reading by an RFID reader. In this embodiment, as shown in fig. 2, the diameter of RFID tag 14 is larger than the diameter of decal member 13.

Fig. 4 is a flowchart of a method for manufacturing medals according to the first embodiment of the present invention. In the method of manufacturing the medal 10, first, the first portion 121 and the second portion 122 constituting the inner pack member 12 are prepared. Next, the RFID tag 14 is first attached to the center of the planar inner bottom portion 121b of the first part 121 (step S41).

Next, the second part 122 is pressed into the first part 121 with the RFID tag 14 attached to the inner bottom part 121b, and the first part 121 and the second part 122 are sealed in a state where the RFID tag 14 is housed in the sealed space inside (step S42). The contact portion of the first portion 121 and the second portion 122 is bonded by an adhesive.

Next, the inner pack member 12 containing the RFID tag 14 therein is held as an insert member in a mold, and the body member 11 is formed by insert injection molding (step S43). Then, in the structure in which the inner cover member 12 and the body member 11 are integrated, the applique members 13 are attached to the two exposed surfaces 12b of the inner cover member 12, respectively, to produce the medal 10 (step S44).

As described above, in the method of manufacturing the token 10 of the present embodiment, the first portion 121 and the second portion 122 constituting the inner pack member 12 are formed in advance so as to form a closed space for enclosing the RFID tag 14 by combining with each other. Therefore, the first portion 121 and the second portion 122 are not significantly deformed at the stage of enclosing the RFID tag 14 and at the stage of manufacturing the token 10, and the RFID tag 14 is protected by the enclosing member 12 in the manufacturing process of the token 10, so that the RFID tag 14 is not subjected to a large external force. Therefore, the possibility of breakage of the RFID tag 14 in the manufacturing process can be reduced.

As described above, in the token 10 of the present embodiment, the RFID tag 14 is located at the substantially center in the thickness direction of the token 10. Thus, the RFID tags 14 are located at a substantially uniform distance from the top and bottom surfaces, regardless of which side of the token 10 is placed face up.

Fig. 5A is a diagram showing a stacked state of a conventional token in which an RFID tag is arranged to be biased to one side in the thickness direction of the token, and fig. 5B is a diagram showing a stacked state of tokens according to the present embodiment in which an RFID tag is arranged at the center in the thickness direction of the token. Fig. 5A and 5B schematically show the medal 100 and the medal 10, and for convenience of explanation of the effect of the present embodiment, the size ratio of the medals is shown differently in the above-described drawings.

As shown in fig. 5A, in the conventional token 100, since the RFID tags 104 are arranged on the surface of one side, when a plurality of tokens 100 are stacked in an arbitrary orientation, the intervals between adjacent RFID tags 104 become uneven. It is experimentally found that when the plurality of RFID tags 104 of the plurality of game chips 100 stacked in this manner are read together at the same time using an RFID reader, the reading is unstable.

On the other hand, as shown in fig. 5B, in the medal 10 of the present embodiment, since the RFID tag 14 is located at the center in the thickness direction of the medal, even in the case where a plurality of medals 10 are stacked in an arbitrary orientation, the intervals between the adjacent medals 10 are uniform. It is found through experiments that when the plurality of RFID tags 14 of the plurality of game chips 10 stacked in this manner are simultaneously read together using an RFID reader, stable reading is possible as compared with the case of fig. 5A.

In order to obtain such an effect, as described above, the RFID tag 14 is preferably disposed at a position within ± 25% of the center of the token 10 in the thickness direction, more preferably at a position within ± 10% of the center of the token 10 in the thickness direction, and still more preferably at a position within ± 5% of the center of the token 10 in the thickness direction.

In the above embodiment, the first portion 121 and the second portion 122 are fixed to each other by press-fitting the second portion 122 into the first portion 121, but the first portion 121 and the second portion 122 may be fixed to each other by engaging the first portion 121 and the second portion 122 with an engaging claw instead of this. In this case, a locking claw is formed on one of the first portion 121 and the second portion 122, and a locking recess that is engaged with the locking claw is formed on the other.

Fig. 6 is a diagram showing a structure of an inner cover member according to a second embodiment of the present invention. In the example of fig. 6, the first portion 121 and the second portion 122 constituting the inner packet member 12 are joined by a joining piece 123. The connecting piece 123 has flexibility, and the angle between the first portion 121 and the second portion 122 can be arbitrarily changed before the first portion 121 and the second portion 122 are combined. With this configuration, the RFID tag 14 is disposed between the first portion 121 and the second portion 122, and the first portion 121 and the second portion 122 are fixed to each other by press-fitting or locking, whereby the RFID tag 14 can be housed in the closed space.

The first portion 121 and the second portion 122 may be coupled to each other in a hinge shape. In this case, the RFID tag 14 may be placed between the first portion 121 and the second portion 122 while the first portion 121 and the second portion 122 are connected to each other, and the first portion 121 and the second portion 122 may be combined with each other by press-fitting or locking the RFID tag 14 in a state where the RFID tag 14 is stored in the closed space.

Fig. 7 is a diagram showing a structure of an inner cover member according to a third embodiment of the present invention. In the example of fig. 7, the inner packet member 12' is formed of a pouch-like film. That is, the sheet-shaped first portion 121 'is partially bonded to the sheet-shaped second portion 122', and is partially opened. The RFID tag 14 is inserted between the first portion 121 'and the second portion 122' from the opening, so that the RFID tag 14 can be sandwiched by the first portion 121 'and the second portion 122'. In this example, the first portion 121 'and the second portion 122' form a closed space therebetween for receiving the RFID tag 14, protecting the RFID tag 14.

The sheet-like first portion 121 'and the sheet-like second portion 122' may be bonded to each other with the RFID tag 14 interposed therebetween. Thereby, the RFID tag 14 cannot be taken out of the inner package member 12'. Further, the sheet-shaped first portion 121 'and the sheet-shaped second portion 122' may not be connected. In this case, the first and second portions 121 'and 122' may be adhered in a state where the first and second portions 121 'and 122' sandwich the RFID tag 14.

Fig. 8 is a sectional view of a token according to a fourth embodiment of the present invention, and fig. 9 is an exploded sectional view of the token according to the fourth embodiment of the present invention. The same components as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the token 10' of the present embodiment, the inner member 12 ″ is thinner than the inner member 12 of the first embodiment. Further, the main body member 11 is injection molded not only to cover the edge of the inner pack member 12' but also to cover the entire surface thereof.

Specifically, the main body member 11 is formed by insert molding an inner cover member 12 ″ having an RFID tag 14 enclosed therein as an insert member, and at this time, the inner cover member 12 ″ is supported by a support member in a mold, so that a hole corresponding to the support member is formed in a surface of the main body member 11' to which the decal member 13 is attached. The hole is covered by the decal member 13 and is not exposed in the finished token 10'.

According to the token 10 'of the present embodiment, since the entire surface of the inner pack member 12 ″ is covered with the body member 11', the RFID tag 14 is not exposed even if the decal member 13 is peeled off.

Fig. 11 is an exploded perspective view of an inner cover member and an RFID tag of a token according to a fifth embodiment of the present invention. The inner member 120 is formed by bonding a first portion 1201 and a second portion 1202. The first portion 1201 and the second portion 1202 have the same shape, and a step portion 1203 is formed at the edge of the circular plate shape, and a circular plate-shaped convex portion 1204 is formed at the center of the circular plate shape. The height of the peripheral land portion 1203 is the same as that of the central convex portion 1204, and the upper surfaces thereof are flat.

Fig. 12 is a plan view of an RFID tag according to a fifth embodiment of the present invention. The RFID tag 14 is of an adhesive type and is formed of a circular sheet-like film. An adhesive is provided on one surface of the film. A circuit 141 is provided at the periphery of the film. An antenna 142 extends from one side of the circuit 141. The antenna 142 extends in a spiral shape along the outer periphery of the film and is connected to the circuit 141. In this way, in the RFID tag 14 of the present embodiment, the antenna is arranged along the outer periphery of the peripheral portion while avoiding the central portion. This enables reception of a wider range of radio waves.

As shown in fig. 11, the RFID tag 14 is substantially centrally aligned with the first part 1201 or the second part 1202 and is adhesively secured to a protrusion 1204 of the first part 1201 or the second part 1202 (on the side opposite to the adhesive side of the RFID tag 14). At this time, the antenna 142 is arranged to avoid the convex portion 1204.

Fig. 13 is an exploded cross-sectional view of an inner cover member and an RFID tag of a token according to a fifth embodiment of the present invention. As described above, first, the adhesive surface of the RFID tag 14 is adhered to the convex portion 1204 of either the first portion 1201 or the second portion 1202 in a center-aligned manner. After that, the step portions 1203 and the convex portions 1204 of the first portion 1201 and the second portion 1202 are bonded to each other with an adhesive. As shown in fig. 13, since the RFID tag 14 has a diameter slightly smaller than the inside of the step portions 1203 of the first and second portions 1201 and 1202 constituting the inner pack member 120, the RFID tag 14 does not interfere with the step portions 1203 of the first and second portions 1201 and 1203 of the second portion 1202 even if they are bonded to each other.

Thus, the inner cover member 12 having the RFID tag 14 built therein can be manufactured, and the RFID tag 14 is fixed in the inner cover member 120 without the circuit or the antenna of the RFID tag 14 being pressed by the first portion 1201 and the second portion 1202 of the inner cover member 12. The first part 1201 and the second part 1202 are aligned and bonded at the mesa 1203 and the convex portion 1204, thereby producing the inner cover member 12 in a circular plate shape.

Fig. 14 is a sectional view of a medal according to a fifth embodiment of the present invention. The main body member 11 is provided so as to enclose a disk-shaped inner cover member 12 enclosing an RFID tag 14. The body member 11 is provided so as to cover the entire periphery of the inner pack member 12 from the side surface of the inner pack member 12 to the peripheral edge portions of both planes. The center of the doughnut-shaped body member 11 holding the inner cover member 12 at the inner edge is exposed at the center of both planes of the inner cover member 12. The decal member 13 is attached to the inner pack member 12 so as to cover the exposed portion.

Thus, the peripheral edge and the side surface of the flat surface of the inner cover 12 enclosing the RFID tag 14 are covered with the main body member 11, and the remaining portion, i.e., the central portion of both flat surfaces, is covered with the decal member 13, so that the inner cover 12 is built in the token without an exposed portion. In this way, since the peripheral edge portion and the side surface of the flat surface are covered with the body member 11, even in a case where an impact is applied to the medal (for example, a case where the medal is dropped), the inner pack member 12 and the RFID tag 14 can be protected from the impact.

Note that the inner bag member 12 and the body member 11 may be made of different base materials (materials). Further, the surface of the inner wrap member 12 may be marked with information for identifying the RFID tag 14 by printing with laser inscription or ink. Thus, even when the RFID tag 14 fails and cannot be read, the RFID tag 14 can be identified by recognizing the mark.

In the above embodiment, the RFID tag 14 is of an adhesive type, but the RFID tag 14 is not limited to this, and may be of a sheet type having no adhesive surface, for example. Further, the RFID tag 14 may be a coil type. Further, the RFID tag 14 may also be of an active type.

In the above embodiment, the medals 10, 10' have a circular plate shape, but the shape of the medals is not limited thereto, and may be, for example, a rectangular plate shape.
