Description

[Technical field]

[0001] The present disclosure relates to RFID tags. [Background technology]

[0002] RFID (Radio Frequency Identification) tags are used in the logistics and retail industries for the purpose of managing individual items. Among them, there are sticker-type RFID tags that are attached to objects with a sticker on the back of the tag, and tag-type RFID tags that are tied to objects with a string. RFID tags are also called wireless tags.

[0003] Fig. 1 is a diagram showing a sticker-type RFID tag. Fig. 2 is a diagram showing a tag-type RFID tag. In particular, the passive-type RFID tag 100 shown in Figs. 1 and 2 has the advantage that the tag information stored in the IC circuit unit 320 of the RFID tag 100 can be read semi-permanently unless damaged, but has the disadvantage that the tag information can be read even when the RFID tag 100 is no longer needed.

[0004] Patent document 1 describes how a command to initialize (erase) information stored in the memory section of an RFID tag circuit element is output to a signal processing circuit, and the signal is transmitted via an antenna to the RFID tag circuit element to be erased, initializing its memory section.

[0005] Patent Document 2 describes a tag communication device that has a radio tag communication unit and a control unit, where the radio tag communication unit writes information indicating that processing has been completed to an area in the radio tag where the first information is stored, and receives the written first information from the radio tag. The control unit determines that processing has been completed when the first information of the radio tag received by the radio tag communication unit is a value indicating that the data in the storage unit has been erased or a value indicating that processing has been completed.

[0006] [Patent Document 1] JP 2006-065662 A [Patent Document 2] JP 2017-004041 A Summary of the Invention [Problem to be solved by the invention]

[0007] Incidentally, when reading tag information from RFID tags at the site of individual item management, tag information from RDIF tags that are no longer needed is also read. This causes inconveniences such as slower reading speed, slower data processing speed, and the need to add an exclusion process to exclude RFID tags that are no longer needed. In order to avoid these inconveniences, it is necessary to store the no longer needed RFID tags in a box with a shielding effect, or to destroy the RFID tags, but the preparation and work required for this is very time-consuming.

[0008] In addition, in Patent Document 1, when initializing the tag information stored in the memory section of the RFID circuit element, it may be necessary for the tag installer and the disposer to share a password, which causes the problem that the initialization process is time-consuming.

[0009] Similarly, in Patent Document 2, when erasing the first information (tag information) stored in the memory area, a password may need to be shared between the tag installer and the discarder, which causes a problem that the initialization work is time-consuming.

[0018] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. FIG. 3A is a diagram showing a sticker-type RFID tag. FIG. 3A shows an X-axis and a Y-axis. In FIG. 3A, the left-right direction is called the longitudinal direction or X-direction, the right direction is called the right side, one longitudinal side or +X-direction, the left direction is called the left side, the other longitudinal side or -X-direction. In FIG. 3, the up-down direction is called the transverse direction or Y-direction, the up direction is called the upper side, one transverse side or +Y-direction, the down direction is called the lower side, the other transverse side or -Y-direction. The depth direction of the paper surface of FIG. 3 is called the front-back direction or Z-direction, the front direction is called the front side or +Z-direction, and the depth direction is called the back side or -Z-direction.

[0019] A sticker-type RFID tag 100A shown in FIG. 3A has a label body 200, an RFID circuit element 300, an adhesive part 400, and a release paper (not shown).

[0020] (Label body 200) FIG. 3B is a diagram showing a label body in an embodiment of the present disclosure. In FIG. 3B, the RFID circuit element 300 is omitted. The label body 200 is a long label. The outer peripheral edge 202 of the label body 200 has an upper edge 202a extending along the longitudinal direction, a lower edge 202b extending along the longitudinal direction and arranged opposite the upper edge 202a in the short direction (Y direction), a right edge 202c extending along the short direction, and a left edge 202d extending along the short direction and arranged opposite the right edge 202c in the longitudinal direction. The lengths L1 of the upper edge 202a and the lower edge 202b are equal to each other. The lengths L2 of the right edge 202c and the left edge 202d are equal to each other.

[0021] The label body 200 has a central portion 204 located in the center in the longitudinal direction (X direction) and having a substantially square region, a one side end portion 206 located on one side in the longitudinal direction (+X direction) from the central portion 204 and having a substantially rectangular region, and an other side end portion 208 located on the other side in the longitudinal direction (-X direction) from the central portion 204 and having a substantially rectangular region. The one side end portion 206 and the other side end portion 208 correspond to "both ends" in this disclosure.

[0022] The central portion 204 has an upper edge 204a, a lower edge 204b, a right edge 204c, and a left edge 204d. The upper edge 204a and the lower edge 204b have a length that is approximately 1 / 3 of the length L1. The right edge 204c and the left edge 204d have a length that is the same as the length L2.

[0023] The one side end 206 has an upper edge 206a, a lower edge 206b, a right edge 206c, and a left edge 206d. The upper edge 206a and the lower edge 206b have a length of about 1 / 3 of the length L1. The right edge 206c and the left edge 206d have the same length as the length L2. The right edge 204c and the left edge 206d are each disposed along a boundary line B1 that separates the center portion 204 and the one side end 206. The boundary line B1 corresponds to the "first boundary" in this disclosure, and in this embodiment, is a line that runs along the right edge 204C and the left edge 206d.

[0024] The other end 208 has an upper edge 208a, a lower edge 208b, a right edge 208c, and a left edge 208d. The upper edge 208a and the lower edge 208b have a length of about 1 / 3 of the length L1. The right edge 208c and the left edge 208d have the same length as the length L2. The left edge 204d and the right edge 208c are each disposed along a boundary line B2 that separates the center portion 204 and the other end 208. The boundary line B2 corresponds to the "second boundary" in this disclosure, and in this embodiment, is a line that runs along the left edge 204d and the right edge 208c.

[0025] The area of ​​the central portion 204 is expressed by a value obtained by multiplying approximately 1 / 3 of the length L1 by the length L2 (≒L1*L2 / 3). The areas of the one end portion 206 and the other end portion 208 are expressed by a value obtained by multiplying approximately 1 / 3 of the length L1 by the length L2 (≒L1*L2 / 3). In other words, the area S1 of each of the one end portion 206 and the other end portion 208 is approximately the same as the area S2 of the central portion 204 (S1≒S2). Preferably, the area of ​​each of the one end portion 206 and the other end portion 208 is equal to or larger than the area of ​​the central portion 204 (S1≧S2).

[0026] The size relationship of the area S1 is set according to the adhesive strength of the adhesive portion 400, which will be described later, and is specifically set based on the results of experiments and simulations. For example, the area S1 may be made smaller according to the adhesive strength of the adhesive portion 400. Therefore, depending on the level of the adhesive strength of the adhesive portion 400, the area S1 may be smaller than the area S2 (S1 <S2)。

[0027] A resin material with high electrical insulation properties is used for the label body 200. Specifically, the label body 200 is made of a resin film having a predetermined thickness, for example, a PET (Polyethylene terephthalate) film.

[0028] (RFID circuit element 300) 3A, the RFID circuit element 300 will be described. The RFID circuit element 300 has a loop antenna section 310, an IC circuit section 320, a capacity hat section 330, and a meander line antenna section 340.

[0029] The loop antenna unit 310 is disposed in the central portion 204. The loop antenna unit 310 transmits and receives signals to and from an antenna on the reader / writer (not shown) side in a non-contact manner. This enables the reader / writer to read predetermined information from a storage unit (described later) and write predetermined information to the storage unit via the loop antenna unit 310.

[0030] The IC circuit section 320 is disposed in the central section 204. The IC circuit section 320 has a rectifier section (not shown) that rectifies the carrier wave received by the loop antenna section 310, a memory section (not shown) that stores a predetermined information signal received by the loop antenna section 310, and a control section (not shown) that controls the operation of the RFID circuit element 300.

[0031] The capacity hat portion 330 is disposed at each of the one side end portion 206 and the other side end portion 208. The capacity hat portion 330 accumulates the energy of the carrier wave rectified by the rectification portion so as to use it as a driving power source for the RFID circuit element 300.

[0032] The meander line antenna section 340 is disposed at each of the one end 206 and the other end 208. The meander line antenna section 340 has one end 341 and the other end 342, with the loop antenna section 310 connected to the one end 341 and the capacity hat section 330 connected to the other end 342. In other words, the conductor extending from the one end 341 of the meander line antenna section 340 disposed at the one end 206 crosses the boundary line B1 and is connected to the loop antenna section 310 disposed at the central section 204. Also, the conductor extending from the one end 341 of the meander line antenna section 340 disposed at the other end 208 crosses the boundary line B2 and is connected to the loop antenna section 310 disposed at the central section 204. Therefore, by cutting the conductor at boundary line B1, one end 341 of meander line antenna unit 340 arranged at one end 206 is electrically disconnected from loop antenna unit 310. Also, by cutting the conductor at boundary line B2, one end 341 of meander line antenna unit 340 arranged at the other end 208 is electrically disconnected from loop antenna unit 310.

[0033] (Adhesive part 400) Next, the adhesive portion 400 will be described with reference to FIGS. 3A and 3B. The adhesive portion 400 is disposed on the back side of the label body 200. For example, an adhesive sticker having adhesiveness is used for the adhesive portion 400. When an adhesive sticker is used as the adhesive portion 400, a release paper (not shown) is disposed so as to sandwich the adhesive sticker between the label body 200 and the front and back directions (Z direction). The adhesive sticker has a substantially rectangular shape so as to cover almost the entire area of ​​each of the one side end 206 and the other side end 208. The one side end 206 and the other side end 208 correspond to the "adjacent portion" of the present disclosure.

[0034] The release paper is peeled off from the adhesive sticker before the RFID tag 100A is attached to an object (not shown) by the adhesive sticker. In the present disclosure, an adhesive may be used as the adhesive portion 400. When an adhesive is used as the adhesive portion 400, the adhesive is applied to the back side of the label body 200.

[0035] Next, a procedure for attaching the RFID tag 100A to an object will be described. In the following description, a case where an adhesive sticker is used as the adhesive portion 400 will be described. First, peel the release paper off the adhesive sticker. Next, hold the adhesive sticker facing the object. Next, the RFID tag 100A is attached to a predetermined position of the object with an adhesive sticker.

[0036] Next, a procedure for disposing of the RFID tag 100A will be described. In the following description, a case where an adhesive sticker is used as the adhesive portion 400 will be described. First, the upper edge 204a of the central portion 204 is pinched with fingers (or a tool) and the central portion 204 is peeled off from the object (a downward load is applied to the central portion 204). As a result, a resistance force against the downward load is generated at the one side end 206 attached to the object by the adhesive sticker, and a shear force is generated along the boundary line B1. Similarly, a resistance force against the downward load is generated at the other side end 208 attached to the object by the adhesive sticker, and a shear force is generated along the boundary line B2.

[0037] Next, when the central portion 204 is peeled off from the object, the RFID tag 100A is broken along the boundary line B1. The RFID tag 100A is also broken along the boundary line B2. As a result, the conductor extending from one end 341 of the meander line antenna portion 340 arranged at the one side end 206 to the loop antenna portion 310 is cut at a position near the boundary line B1. Also, the conductor extending from one end 341 of the meander line antenna portion 340 arranged at the other side end 208 to the loop antenna portion 310 is cut at a position near the boundary line B2. As a result, it is possible to peel off only the central portion 204 from the object and discard it while leaving both ends 206 and 208 attached to the object. By destroying the loop antenna portion 310, the reader / writer cannot read predetermined information from the storage portion via the loop antenna portion 310 (it no longer functions as an RFID tag), so it is possible to discard the RFID tag.

[0038] The RFID tag 100A in the above embodiment is a label-shaped RFID tag in which a wireless tag circuit element 300 is disposed on a label body 200. The label body 200 has a rectangular outer peripheral edge 202, a central portion 204 located in the center of the longitudinal direction of the label body 200, a one side end portion 206 located at one end of the longitudinal direction of the label body 200, and an other side end portion 208 located at the other end of the longitudinal direction of the label body 200. The wireless tag circuit element 300 is disposed in the central portion 204 and has a loop antenna portion 310 for transmitting and receiving information to and from a reader / writer, and a loop antenna portion 310 disposed in the central portion and for receiving and transmitting information to and from a reader / writer. The antenna device is equipped with a memory unit which stores predetermined information received, a capacity hat unit 330 which is arranged at each of the one side end 206 and the other side end 208 and which accumulates the carrier wave received by the loop antenna unit 310 as energy, and a meander line antenna unit 340 which is arranged at each of the one side end 206 and the other side end 208 and has one end 341 and the other end 342, with the loop antenna unit 310 connected to one end 341 and the capacity hat unit 330 connected to the other end 342, and an adhesive unit 400 having adhesive properties is provided at each of the one side end 206 and the other side end 208.

[0039] With the above configuration, by pinching the upper edge of the central portion 204 and peeling the central portion 204 from the object, the RFID tag 100A is broken along the boundary line B1 and the boundary line B2. This makes it possible to peel only the central portion 204 from the object and discard it while leaving both ends 206, 208 attached to the object. Destruction of the loop antenna portion 310 causes the RFID tag 100A to become non-functional. Because the RFID tag 100A can be easily and reliably rendered non-functional simply by peeling the central portion 204 from the object, the labor required to discard the RFID tag can be reduced.

[0040] In the RFID tag 100A in the above embodiment, the loop antenna section 310 and the IC circuit section 320 are arranged in the center section 204, and the capacity hat section 330 and the meander line antenna section 340 are arranged in both ends 206, 208, but the present disclosure is not limited to this, and may be in the opposite form. That is, the capacity hat section 330 and the meander line antenna section 340 may be arranged in the center section 204, and the loop antenna section 310 and the IC circuit section 320 may be arranged in both ends 206, 208. As a result, in the disposal process of the RFID tag, the IC circuit section 320 and the capacity hat section 330 are separated, and the IC circuit section 320 cannot operate by the power of the capacity hat section 330, so that it becomes difficult for a reader / writer to read tag information from the storage section constituting the IC circuit section 320.

[0041] The present disclosure is not limited to the above embodiment. For example, the label body 200 has a long outer peripheral edge, one side portion located on one side of the longitudinal direction of the label body 200, and the other side portion located on the other side of the longitudinal direction of the label body 200, and the RFID circuit element 300 includes a loop antenna portion 310 arranged on the one side portion for transmitting and receiving information with a reader / writer, a storage portion arranged on the one side portion for storing predetermined information received by the loop antenna portion 310, a capacity hat portion 330 arranged on the other side portion for storing the carrier wave received by the loop antenna portion 310 as energy, and a meander line antenna portion 340 arranged on the other side portion, having one end and the other end, with the loop antenna portion 310 connected to one end and the capacity hat portion 330 connected to the other end, and an adhesive portion 400 having adhesiveness may be provided on the other side portion. The other side portion corresponds to the "adjacent portion" of the present disclosure.

[0042] (Variation 1) Next, various modified examples of the present embodiment will be described. In the description of the various modified examples, the configurations different from the RFID tag in the above embodiment will be mainly described, and the same configurations will be denoted by the same reference numerals and the description thereof will be omitted.

[0043] First, the RFID tag 100A in the first modification of the present embodiment will be described with reference to FIG. 4. FIG. 4 is a diagram showing a sticker-type RFID tag in the first modification of the present embodiment. The RFID tag 100A shown in FIG. 4 has a gripping portion 210. The gripping portion 210 is a portion that protrudes in a trapezoidal shape upward (+X direction) from the upper edge 202a of the central portion 204. The gripping portion 210 and the central portion 204 are integrally formed. Since the gripping portion 210 protrudes from the upper edge 202a, the gripping portion 210 can be easily pinched with fingers. Furthermore, since the gripping portion 210 and the central portion 204 are integrally formed, the central portion 204 can be peeled off from the object via the gripping portion 210.

[0044] A procedure for disposing of the RFID tag 100A will be described in Modification 1. In the following description, the case where an adhesive sticker is used as the adhesive portion 400 will also be described. First, the gripping portion 210 is pinched with fingers (or a tool) and the central portion 204 is peeled off from the object. This generates a shear force along the boundary line B1 between the central portion 204 and the one side end 206. Also, a shear force is generated along the boundary line B2 between the central portion 204 and the other side end 208. The procedure thereafter is the same as in the above embodiment, and therefore a description thereof is omitted. In the RFID tag 100A in the first modification, the gripping portion 210 can be easily pinched by hand, and the central portion 204 can be peeled off from the object via the gripping portion 210. This makes it possible to more easily perform the task of disposing of the RFID tag.

[0045] (Variation 2) Next, an RFID tag 100A according to a second modification of the present embodiment will be described with reference to Fig. 5. Fig. 5 is a diagram showing a sticker-type RFID tag according to the second modification of the present embodiment. RFID tag 100A shown in Fig. 5 has a notch 220 on one side and a notch 230 on the other side.

[0046] The one-side cut portion 220 is a portion cut so as to extend from the upper edge 204a of the central portion 204 along the boundary line B1.

[0047] The other-side cut portion 230 is a portion cut so as to extend from the upper edge 204a of the central portion 204 along the boundary line B2.

[0048] The RFID tag 100A in the second modification has a one-side notch 220 and an other-side notch 230. This allows the RFID tag 100A to break along the boundary line B1 and the boundary line B2 even with a small shear force, making it even easier to dispose of the RFID tag.

[0049] (Variation 3) The RFID tag 100A in each of the above-described embodiment, modification 1, and modification 2 is a sticker-type RFID tag that is attached to an object (not shown) by the adhesive part 400. In contrast, there is a tag-type RFID tag that is fastened to an object by a string or the like. The tag-type RFID tag does not have the adhesive part 400, and therefore has the effect of making it possible to reduce the number of parts.

[0050] Next, a tag-type RFID tag in Variation 3 of this embodiment will be described with reference to Figs. 6, 7A, and 7B. Fig. 6 is a diagram showing a tag-type RFID tag in Variation 3 of this embodiment with the string removed. Fig. 7A is a diagram showing a tag-type RFID tag in Variation 3 with the string attached. Fig. 7B is a diagram showing a discarded tag-type RFID tag in Variation 3. Tag-type RFID tag 100B has string 240 (see Fig. 7A) for tying RFID tag 100B to an object. A through-hole 250 for passing string 240 through is provided in center portion 204.

[0051] The RFID tag 100B in the third modification has the following configuration. This is a card-type RFID tag in which a wireless tag circuit element 300 is arranged in a card body 200B. The wireless tag circuit element 300 comprises a loop antenna section 310 which transmits and receives information to and from a reader / writer, and an IC circuit section 320 which is connected to the loop antenna section 310 and stores predetermined information. The card body 200B has a through hole 250 which penetrates the area surrounded by the loop antenna section 310.

[0052] The card body 200B shown in FIG. 7A is an elongated card whose long side direction (X direction) is the long side direction.

[0053] Next, a procedure for disposing of the RFID tag 100B will be described. In the following description, it is assumed that the string 240 passed through the through hole 250 is tied to an object (not shown). First, for example, the central portion 204 is grasped and pulled away from the object (a downward load F is applied to the central portion 204). As a result, the string 240 threaded through the through hole 250 is pulled in the vertical direction, and a resistance force against the downward load F is generated in the string 240, so that a shear force is generated by the string 240 at the peripheral portion of the through hole 250 (the portion where the string 240 abuts).

[0054] Next, when the central portion 204 is pulled away from the object, the peripheral portion of the through-hole 250 is damaged toward the position of the upper edge 202a by the shearing force of the string 240. Then, the damaged portion reaches the outside of the area surrounded by the loop antenna portion 310, destroying the loop antenna portion 310 (see FIG. 7B). The destruction of the loop antenna portion 310 causes the RFID tag 100B to malfunction. Therefore, it is sufficient to discard the RFID tag 100B after confirming that the loop antenna portion 310 is destroyed. Note that the damaged portion shown in FIG. 7B reaches the upper edge 202a, and the string 240 comes off from the RFID tag 100B, so that it is possible to easily confirm that the loop antenna portion 310 is destroyed.

[0055] In the RFID tag 100B in the third modification, the through hole 250 for passing the string 240 through is provided in the central portion 204. This makes it possible to easily and reliably disable the RFID tag 100B simply by pulling the central portion 204 away from the target object, thereby reducing the number of steps required to dispose of the RFID tag 100B.

[0056] (Variation 4) Next, a tag-type RFID tag in Variation 4 of the present embodiment will be described with reference to Fig. 8. Fig. 8 is a diagram showing a tag-type RFID tag in Variation 4. The tag-type RFID tag 100C shown in Fig. 8 has a tag body 200C. The tag body 200C shown in Fig. 8 is an elongated tag with its long side direction (Y direction) as its long side direction. In the tag body 200C, one side end 206, a central portion 204, and another side end 208 are arranged in this order from the top.

[0057] In the above-mentioned modified example 3, the RFID circuit element 300 is disposed over almost the entire area of ​​the card body 200B. In contrast, in the above-mentioned modified example 4, the RFID circuit element 300 is disposed over almost half the area of ​​the card body 200C. Also, in the above-mentioned modified example 3, the card body 200B is tied to an object by the string 240 with its upper edge 202a facing upward (+Y direction). In contrast, in the above-mentioned modified example 4, the card body 200C is tied to an object (not shown) by the string 240 with its right edge 202c facing upward (+Y direction).

[0058] Next, a procedure for disposing of the RFID tag 100C will be described. In the following description, it is assumed that the string 240 passed through the through hole 250 is tied to an object (not shown). First, for example, the other end 208 is grasped and pulled away from the object (a downward load F is applied to the other end 208). As a result, the string 240 threaded through the through hole 250 is pulled in the vertical direction, and a resistance to the downward load F is generated in the string 240, so that a shear force is generated by the string 240 at the peripheral portion of the through hole 250 (the portion where the string 240 abuts).

[0059] Next, when the other end 208 is pulled further away from the object, the shearing force of the string 240 causes the periphery of the through-hole 250 to break toward the position of the right edge 202c (the edge located on the upper side as shown in FIG. 8). Then, the broken part moves from the area surrounded by the loop antenna part 310 to the outside of said area, destroying the loop antenna part 310. The destruction of the loop antenna part 310 causes the RFID tag 100C to malfunction. Therefore, it is sufficient to discard the RFID tag 100B after confirming that the loop antenna part 310 has been destroyed.

[0060] In the RFID tag 100C in the fourth modification, the function of the RFID tag 100C can be easily and reliably disabled simply by pulling the other end 208 away from the target object, and it is possible to reduce the number of steps required to dispose of the RFID tag 100C. Furthermore, even if the RFID tag 100C is relatively large compared to the size of the wireless tag circuit element 300, by providing the through-hole 250 in the area surrounded by the loop antenna part 310, the RFID tag 100C can be easily disposed of.

[0061] (Variation 5) Next, a tag-type RFID tag in Variation 5 of the present embodiment will be described with reference to Fig. 9. Fig. 9 is a diagram showing a tag-type RFID tag in Variation 5. The tag-type RFID tag 100D shown in Fig. 9 has a tag body 200D. The tag body 200D shown in Fig. 9 is an elongated tag with its long side direction (Y direction) as its long side direction. In the tag body 200C, one side end 206, a central portion 204, and another side end 208 are arranged in this order from the top.

[0062] In the above-mentioned modification 4, the RFID circuit element 300 is arranged in approximately half of the area of ​​the card body 200C. In contrast, in the above-mentioned modification 5, the RFID circuit element 300 is arranged in the area of ​​one side end 206 of the card body 200D. In the above-mentioned modification 4, the components constituting the RFID circuit element 300, such as the loop antenna section 310, are arranged in the longitudinal direction (Y direction). In contrast, in the above-mentioned modification 5, the components are arranged in the lateral direction (X direction). Note that in the modification 5, as in the above-mentioned modification 4, the card body 200D is tied to an object (not shown) by the string 240 with its right side edge 202c facing upward (+Y direction).

[0063] Next, a procedure for disposing of the RFID tag 100D will be described. In the following description, it is assumed that the string 240 passed through the through hole 250 is tied to an object (not shown). First, for example, the other end 208 is grasped and pulled away from the object (a downward load F is applied to the other end 208). As a result, the string 240 threaded through the through hole 250 is pulled in the vertical direction, and a resistance to the downward load F is generated in the string 240, so that a shear force is generated by the string 240 at the peripheral portion of the through hole 250 (the portion where the string 240 abuts).

[0064] Next, when the other end 208 is pulled further away from the object, the shearing force of the string 240 causes the periphery of the through-hole 250 to break toward the position of the right edge 202c (the edge located on the upper side as shown in FIG. 9). Then, the broken part moves from the area surrounded by the loop antenna part 310 to the outside of said area, destroying the loop antenna part 310. The destruction of the loop antenna part 310 causes the RFID tag 100D to malfunction. Therefore, it is sufficient to discard the RFID tag 100B after confirming that the loop antenna part 310 has been destroyed.

[0065] In the RFID tag 100D in the fifth modification, the function of the RFID tag 100D can be easily and reliably disabled by simply pulling the other end 208 away from the object, and the labor required to dispose of the RFID tag 100D can be reduced. Even if the RFID tag 100D is relatively large, the RFID tag 100D can be easily disposed of by providing the through hole 250 in the area surrounded by the loop antenna unit 310. In the fifth modification, the loop antenna unit 310 (through hole 250) is disposed in the vicinity of the edge (right edge 202c) located on the upper side of the tag body 200D, compared to the fourth modification. Therefore, even if the downward load F is relatively small, the broken part reaches the edge located on the upper side due to the shear force of the string 240, and the string 240 comes off the RFID tag 100B. This makes it easy to confirm that the loop antenna unit 310 is broken. From the above, in order to easily dispose of the RFID tag 100C, which is relatively large compared to the size of the wireless tag circuit element 300, it is preferable to place the loop antenna part 310 (through hole 250) in a position near the edge located on the upper side of the tag body 200C when the RFID tag 100C is tied up.
