Description

Technical Field

[0001] The present disclosure relates to RFID tags.

Background Art

[0002] In the logistics industry, retail industry, etc., RFID (Radio Frequency Identification) tags are used for individual item management. Among them, there are seal-type RFID tags attached to an object by a seal on the back of the tag, and tag-type RFID tags tied to an object with a string or the like. Note that RFID tags are also called wireless tags.

[0003] FIG. 1 is a diagram showing a seal-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 section 320 of the RFID tag 100 can be read semi-permanently as long as the RFID tag 100 is not damaged. On the other hand, it has the disadvantage that the tag information can be read even when the RFID tag 100 becomes unnecessary.

[0004] Patent Document 1 describes that a command for initializing (erasing) information stored in a memory section of a wireless tag circuit element is output to a signal processing circuit, and the signal is transmitted via an antenna to the wireless tag circuit element to be erased, and its memory section is initialized.

[0005] Further, Patent Document 2 describes a tag communication device having a wireless tag communication section and a control section. The wireless tag communication section writes information indicating that it has been processed into an area where the first information of the wireless tag is stored, and receives the first information after writing from the wireless tag. The control section determines that the process has been completed when the first information of the wireless tag received by the wireless tag communication section is a value indicating that the data in the storage section has been erased or a value indicating that the process has been completed.

[0007] By the way, when reading the tag information of an RFID tag at the site of individual item management, the tag information of an RFID tag that has become unnecessary is also read, resulting in inconveniences such as a decrease in the reading speed, a decrease in the data processing speed, and the addition of an exclusion process for excluding unnecessary RFID tags. Further, in order to avoid these inconveniences, it is necessary to store unnecessary RFID tags in a box with a shielding effect or to destroy the RFID tags, but a lot of labor is required for the preparation and work.

[0008] Also, in Patent Document 1, when initializing the tag information stored in the memory unit of the wireless tag circuit element, there is a case where password sharing is required between the tag attachers and the discarders, and there is a problem that the initialization work is troublesome.

[0009] Similarly, in Patent Document 2, when erasing the first information (tag information) stored in the storage area, there is a case where password sharing is required between the tag attachers and the discarders, and there is a problem that the initialization work is troublesome.

[0010] An object of the present disclosure is to provide an RFID tag capable of suppressing the man-hours for the work of discarding an RFID tag. [Means for Solving the Problems]

MODE FOR CARRYING OUT THE INVENTION

[0018] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. FIG. 3A is a diagram showing a seal type RFID tag. An X-axis and a Y-axis are drawn in FIG. 3A. In FIG. 3A, the horizontal direction is referred to as the longitudinal direction or the X direction, the right direction is referred to as the right side, one side in the longitudinal direction, or the +X direction, and the left direction is referred to as the left side, the other side in the longitudinal direction, or the -X direction. Also, in FIG. 3, the vertical direction is referred to as the short side direction or the Y direction, the upward direction is referred to as the upper side, one side in the short side direction, or the +Y direction, and the downward direction is referred to as the lower side, the other side in the short side direction, or the -Y direction. The depth direction of the paper surface of FIG. 3 is referred to as the front-back direction or the Z direction, the front direction is referred to as the front side or the +Z direction, and the depth direction is referred to as the back side or the -Z direction.

[0019] The seal type RFID tag 100A shown in FIG. 3A includes a label main body 200, a wireless tag circuit element 300, an adhesive portion 400, and a release paper (not shown).

[0020] (Label main body 200) FIG. 3B is a diagram showing a label body according to an embodiment of the present disclosure. In FIG. 3B, the wireless tag circuit element 300 is omitted. The label body 200 is a long label. The outer peripheral edge 202 of the label body 200 includes an upper edge 202a extending along the longitudinal direction, a lower edge 202b extending along the longitudinal direction and disposed opposite to 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 disposed opposite to 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 at the central portion in the longitudinal direction (X direction) and having a substantially square region, a one-side end portion 206 located on one side (+X direction) in the longitudinal direction from the central portion 204 and having a substantially rectangular region, and the central portion 204 located on the other side (-X direction) in the longitudinal direction and having a substantially rectangular region. The one-side end portion 206 and the other-side end portion 208 correspond to the "both end portions" of the present 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 of about 1 / 3 of the length L1. The right edge 204c and the left edge 204d have the same length as the length L2.

[0023] One side end 206 has an upper side edge 206a, a lower side edge 206b, a right side edge 206c, and a left side edge 206d. The upper side edge 206a and the lower side edge 206b have a length of approximately 1 / 3 of the length L1. The right side edge 206c and the left side edge 206d have the same length as the length L2. Each of the right side edge 204c and the left side edge 206d is arranged along a boundary line B1 that demarcates the central portion 204 and the one side end 206. The boundary line B1 corresponds to the "first boundary portion" in the present disclosure. In the present embodiment, it is a line along the right side edge 204C and a line along the left side edge 206d.

[0024] The other side end 208 has an upper side edge 208a, a lower side edge 208b, a right side edge 208c, and a left side edge 208d. The upper side edge 208a and the lower side edge 208b have a length of approximately 1 / 3 of the length L1. The right side edge 208c and the left side edge 208d have the same length as the length L2. Each of the left side edge 204d and the right side edge 208c is arranged along a boundary line B2 that demarcates the central portion 204 and the other side end 208. The boundary line B2 corresponds to the "second boundary portion" in the present disclosure. In the present embodiment, it is a line along the left side edge 204d and a line along the right side edge 208c.

[0025] The area of the central portion 204 is represented by a numerical value obtained by multiplying the length L2 by a length of approximately 1 / 3 of the length L1 (≒L1*L2 / 3). The area of each of the one side end 206 and the other side end 208 is represented by a numerical value obtained by multiplying the length L2 by a length of approximately 1 / 3 of the length L1 (≒L1*L2 / 3). That is, the area S1 of each of the one side end 206 and the other side end 208 is approximately the same size as the area S2 of the central portion 204 (S1≒S2). Preferably, the area of each of the one side end 206 and the other side end 208 is equal to or greater than the area of the central portion 204 (S1≧S2).

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

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

[0028] (Wireless tag circuit element 300) Next, the wireless tag circuit element 300 will be described with reference to FIG. 3A. The wireless tag circuit element 300 includes a loop antenna part 310, an IC circuit part 320, a capacitor hat part 330, and a meander line antenna part 340.

[0029] The loop antenna part 310 is disposed at the central part 204. The loop antenna part 310 transmits and receives signals in a non-contact manner with an antenna on the reader / writer (not shown) side. Thereby, the reader / writer can read predetermined information from a storage part described later via the loop antenna part 310 and can write the predetermined information into the storage part.

[0030] The IC circuit part 320 is disposed at the central part 204. The IC circuit part 320 includes a rectifying part (not shown) that rectifies the carrier wave received by the loop antenna part 310, a storage part (not shown) that stores a predetermined information signal received by the loop antenna part 310, and a control part (not shown) that controls the operation of the wireless tag circuit element 300.

[0031] The capacitor hat parts 330 are disposed at each of one side end part 206 and the other side end part 208. The capacitor hat parts 330 accumulate the energy of the carrier wave rectified by the rectifying part so as to be a driving power source for the wireless tag circuit element 300.

[0032] The meander line antenna portion 340 is disposed at each of one side end portion 206 and the other side end portion 208. The meander line antenna portion 340 has one end 341 and the other end 342, and the loop antenna portion 310 is connected to the one end 341, and the capacitance hat portion 330 is connected to the other end 342. In other words, the conducting wire extended from one end 341 of the meander line antenna portion 340 disposed at the one side end portion 206 is connected to the loop antenna portion 310 disposed at the central portion 204 across the boundary line B1. Further, the conducting wire extended from one end 341 of the meander line antenna portion 340 disposed at the other side end portion 208 is connected to the loop antenna portion 310 disposed at the central portion 204 across the boundary line B2. Therefore, by cutting the conducting wire at the position of the boundary line B1, the one end 341 of the meander line antenna portion 340 disposed at the one side end portion 206 and the loop antenna portion 310 are electrically disconnected. Further, by cutting the conducting wire at the position of the boundary line B2, the one end 341 of the meander line antenna portion 340 disposed at the other side end portion 208 and the loop antenna portion 310 are electrically disconnected.

[0033] (Adhesive portion 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 surface of the label body 200. For example, an adhesive seal having adhesiveness is used for the adhesive portion 400. When the adhesive seal is used as the adhesive portion 400, a release paper (not shown) is disposed so as to sandwich the adhesive seal with the label body 200 in the front-back direction (Z direction). The adhesive seal has a substantially rectangular shape so as to cover substantially the entire area of each of the one side end portion 206 and the other side end portion 208. Note that the one side end portion 206 and the other side end portion 208 correspond to the "adjacent portions" of the present disclosure.

[0034] The release paper is peeled off from the adhesive seal before the RFID tag 100A is attached to an object (not shown) by the adhesive seal. 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, the procedure for attaching the RFID tag 100A to an object will be described. In the following description, the case where an adhesive seal is used as the adhesive portion 400 will be described. First, peel off the release paper from the adhesive seal. Next, hold the adhesive seal so as to face the object. Next, attach the RFID tag 100A to a predetermined position of the object with the adhesive seal.

[0036] Next, the procedure for discarding the RFID tag 100A will be described. Also in the following description, the case where an adhesive seal is used as the adhesive portion 400 will be described. First, pinch the upper edge 204a of the central portion 204 with a finger (or tool) and peel the central portion 204 from the object (apply a downward load to the central portion 204). As a result, a resistance force against the downward load is generated at one side end portion 206 attached to the object by the adhesive seal, so that a shearing force is generated along the boundary line B1. Similarly, a resistance force against the downward load is generated at the other side end portion 208 attached to the object by the adhesive seal, so that a shearing force is generated along the boundary line B2.

[0037] Next, further, when the central portion 204 is peeled off from the object, the RFID tag 100A is broken along the boundary line B1. Also, the RFID tag 100A is broken along the boundary line B2. As a result, the conductor extending from one end 341 of the meander line antenna portion 340 disposed at the one-side end portion 206 to the loop antenna portion 310 is cut at a position near the boundary line B1. Further, the conductor extending from one end 341 of the meander line antenna portion 340 disposed at the other-side end portion 208 to the loop antenna portion 310 is cut at a position near the boundary line B2. As described above, with both end portions 206 and 208 attached to the object, it becomes possible to peel off and discard only the central portion 204 from the object. Since the loop antenna portion 310 is destroyed and the reader / writer cannot read predetermined information from the storage portion via the loop antenna portion (it no longer functions as an RFID tag), the RFID tag can be discarded.

[0038] The RFID tag 100A in the above embodiment is a label-shaped RFID tag in which the wireless tag circuit element 300 is disposed on the label main body 200. The label main body 200 has a rectangular outer peripheral edge 202, a central portion 204 located at the center in the longitudinal direction of the label main body 200, a one-side end portion 206 located at one side end in the longitudinal direction of the label main body 200, and a the other-side end portion 208 located at the other side end in the longitudinal direction of the label main body 200. The wireless tag circuit element 300 includes a loop antenna portion 310 disposed in the central portion 204 for transmitting and receiving information with the reader / writer, a storage portion disposed in the central portion for storing predetermined information received by the loop antenna portion, capacitor hat portions 330 disposed at each of the one-side end portion 206 and the other-side end portion 208 for accumulating the carrier wave received by the loop antenna portion 310 as energy, and meander line antenna portions 340 disposed at each of the one-side end portion 206 and the other-side end portion 208, having one end 341 and the other end 342, with the loop antenna portion 310 connected to the one end 341 and the capacitor hat portion 330 connected to the other end 342. Adhesive portions 400 having adhesiveness are provided at each of the one-side end portion 206 and the other-side end portion 208.

[0039] With the above configuration, if the upper edge of the central portion 204 is pinched and the central portion 204 is peeled off from the object, the RFID tag 100A is broken along the boundary line B1 and the boundary line B2. As a result, it is possible to attach both end portions 206 and 208 to the object and peel off and discard only the central portion 204 from the object. When the loop antenna portion 310 is destroyed, the RFID tag 100A becomes dysfunctional. Since the RFID tag 100A can be made dysfunctional simply and surely only by the operation of peeling off the central portion 204 from the object, the man-hours for discarding the RFID tag can be reduced.

[0040] In the RFID tag 100A in the above embodiment, the loop antenna portion 310 and the IC circuit portion 320 are arranged in the central portion 204, and the capacitor hat portion 330 and the meander line antenna portion 340 are arranged at both end portions 206 and 208. However, the present disclosure is not limited to this, and the reverse aspect may also be possible. That is, the capacitor hat portion 330 and the meander line antenna portion 340 may be arranged in the central portion 204, and the loop antenna portion 310 and the IC circuit portion 320 may be arranged at both end portions 206 and 208. Thereby, in the RFID tag disposal process, the IC circuit portion 320 and the capacitor hat portion 330 are separated, and since the IC circuit portion 320 cannot be operated by the power of the capacitor hat portion 330, it becomes difficult for the reader / writer to read the tag information from the storage portion constituting the IC circuit portion 320.

[0041] In addition, the present disclosure is not limited to the above-described embodiments. For example, the label body 200 has a long outer peripheral edge, a first side portion located on one side in the longitudinal direction of the label body 200, and a second side portion located on the other side in the longitudinal direction of the label body 200. The wireless tag circuit element 300 includes a loop antenna portion 310 disposed on the first side portion for transmitting and receiving information with a reader / writer, a storage portion disposed on the first side portion for storing predetermined information received by the loop antenna portion 310, a capacitive hat portion 330 disposed on the second side portion for accumulating the carrier wave received by the loop antenna portion 310 as energy, and a meander line antenna portion 340 disposed on the second side portion having one end and the other end, with the loop antenna portion 310 connected to one end and the capacitive hat portion 330 connected to the other end. An adhesive portion 400 having adhesiveness may be provided on the second side portion. Note that the second side portion corresponds to the "adjacent portion" of the present disclosure.

[0042] (Modification Example 1) Next, various modification examples of the present embodiment will be described. In the description of the various modification examples, configurations different from those of the RFID tag in the above-described embodiment will be mainly described, and the same configurations will be denoted by the same reference numerals and their description will be omitted.

[0043] First, the RFID tag 100A in Modification Example 1 of the present embodiment will be described with reference to FIG. 4. FIG. 4 is a diagram showing a seal-type RFID tag in Modification Example 1 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 side edge 202a of the central portion 204. The gripping portion 210 and the central portion 204 are integrally formed. By protruding the gripping portion 210 from the upper side edge 202a, it becomes possible to easily pick up the gripping portion 210 with a finger. Furthermore, since the gripping portion 210 and the central portion 204 are integrally formed, it becomes possible to peel off the central portion 204 from an object through the gripping portion 210.

[0044] In Modification 1, the procedure for discarding the RFID tag 100A will be described. In the following description as well, the case where an adhesive seal is used as the adhesive portion 400 will be described. First, grasp the gripping portion 210 with a finger (or a tool) and peel the central portion 204 from the object. As a result, a shearing force is generated along the boundary line B1 between the central portion 204 and one side end portion 206. Also, a shearing force is generated along the boundary line B2 between the central portion 204 and the other side end portion 208. Since the subsequent procedure is the same as that in the above embodiment, the description thereof will be omitted. In the RFID tag 100A in Modification 1, the gripping portion 210 can be easily grasped by hand, and the central portion 204 can be peeled from the object through the gripping portion 210. As a result, the operation for discarding the RFID tag can be performed more easily.

[0045] (Modification 2) Next, the RFID tag 100A in Modification 2 of the present embodiment will be described with reference to FIG. 5. FIG. 5 is a diagram showing a seal type RFID tag in Modification 2 of the present embodiment. The RFID tag 100A shown in FIG. 5 has a one-side cut portion 220 and an other-side cut portion 230.

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

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

[0048] In the RFID tag 100A in Modification 2, it has the one-side cut portion 220 and the other-side cut portion 230. As a result, even with a small shearing force, the RFID tag 100A is broken along the boundary line B1 and the boundary line B2, so that the operation for discarding the RFID tag can be performed even more easily.

[0049] (Modification 3) In each of the above-described embodiment, Modification 1, and Modification 2, the RFID tag 100A is a seal-type RFID tag that is attached to an object (not shown) by the adhesive portion 400. On the other hand, there is a tag-type RFID tag that is attached to an object with a string or the like. Since the tag-type RFID tag does not have the adhesive portion 400, it has the effect of reducing the number of parts.

[0050] Next, the tag-type RFID tag in Modification 3 of the present embodiment will be described with reference to FIGS. 6, 7A, and 7B. FIG. 6 is a diagram showing a tag-type RFID tag from which the string in Modification 3 of the present embodiment has been removed. FIG. 7A is a diagram showing a tag-type RFID tag to which the string in Modification 3 is attached. FIG. 7B is a diagram showing a discarded tag-type RFID tag in Modification 3. The tag-type RFID tag 100B has a string 240 (see FIG. 7A) for attaching the RFID tag 100B to an object. The through-hole 250 for passing the string 240 is provided in the central portion 204.

[0051] The RFID tag 100B in Modification 3 has the following configuration. It is a tag-type RFID tag in which the wireless tag circuit element 300 is arranged on the tag main body 200B. The wireless tag circuit element 300 includes a loop antenna portion 310 that transmits and receives information to and from a reader / writer, and an IC circuit portion 320 that is connected to the loop antenna portion 310 and stores predetermined information. The tag main body 200B has a through-hole 250 that penetrates the region surrounded by the loop antenna portion 310.

[0052] The tag main body 200B shown in FIG. 7A is a long tag having the longitudinal direction (X direction) as the long dimension direction.

[0053] Next, the procedure for discarding 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 attached to an object (not shown). First, for example, hold the central portion 204 and pull it away from the object (apply a downward load F to the central portion 204). As a result, the string 240 passed 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. Therefore, a shearing force by the string 240 is generated at the peripheral edge of the through-hole 250 (the portion where the string 240 abuts).

[0054] Next, when the central portion 204 is further pulled away from the object, the peripheral edge of the through-hole 250 is damaged toward the position of the upper side edge 202a by the shearing force of the string 240. Then, when the damaged portion reaches outside the region surrounded by the loop antenna portion 310 from the region surrounded by the loop antenna portion 310, the loop antenna portion 310 is destroyed (see FIG. 7B). When the loop antenna portion 310 is destroyed, the RFID tag 100B becomes malfunctioning. Therefore, after confirming that the loop antenna portion 310 is destroyed, the RFID tag 100B may be discarded. Note that the damaged portion shown in FIG. 7B reaches the upper side edge 202a and the string 240 comes off from the RFID tag 100B, so it becomes possible to easily confirm that the loop antenna portion 310 is destroyed.

[0055] In the RFID tag 100B in Modification 3, the through-hole 250 for passing the string 240 is provided in the central portion 204. Thereby, it becomes possible to simply and surely disable the RFID tag 100B only by the operation of pulling the central portion 204 away from the object, and it becomes possible to reduce the man-hours for discarding the RFID tag 100B.

[0056] (Modification 4) Next, the sheet-type RFID tag in Modification 4 of the present embodiment will be described with reference to FIG. 8. FIG. 8 is a diagram showing the sheet-type RFID tag in Modification 4. The sheet-type RFID tag 100C shown in FIG. 8 has a sheet body 200C. The sheet body 200C shown in FIG. 8 is a long sheet having the longitudinal direction (Y direction) as the long direction. In the sheet body 200C, a one-side end portion 206, a central portion 204, and the other-side end portion 208 are arranged in order from the upper side.

[0057] In the above Modification 3, the wireless tag circuit element 300 is arranged in almost the entire area of the ticket main body 200B. On the other hand, in Modification 4, the wireless tag circuit element 300 is arranged in almost half of the area of the ticket main body 200C. Further, in the above Modification 3, the ticket main body 200B is tied to an object by a string 240 with its upper side edge 202a facing upward (+Y direction). On the other hand, in Modification 4, the ticket main body 200C is tied to an object (not shown) by a string 240 with its right side edge 202c facing upward (+Y direction).

[0058] Next, the procedure for discarding 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, hold the other end portion 208 and pull it away from the object (apply a downward load F to the other end portion 208). As a result, the string 240 passed 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. Therefore, a shearing force by the string 240 is generated at the peripheral portion of the through hole 250 (the portion where the string 240 abuts).

[0059] Next, if the other end portion 208 is further pulled away from the object, the peripheral portion of the through hole 250 is damaged toward the position of the right side edge 202c (the edge located on the upper side shown in FIG. 8) by the shearing force of the string 240. Then, when the damaged portion reaches outside the area surrounded by the loop antenna portion 310, the loop antenna portion 310 is destroyed. When the loop antenna portion 310 is destroyed, the RFID tag 100C becomes dysfunctional. Therefore, after confirming that the loop antenna portion 310 is destroyed, the RFID tag 100B may be discarded.

[0060] In the RFID tag 100C in Modification Example 4, it is possible to simply and surely disable the RFID tag 100C only by the operation of pulling the other end portion 208 away from the object, and it is possible to reduce the man-hours for disposing of the RFID tag 100C. Further, even for the relatively large RFID tag 100C with respect to the size of the wireless tag circuit element 300, by providing the through hole 250 in the region surrounded by the loop antenna portion 310, it is possible to dispose of the RFID tag 100C with a simple operation.

[0061] (Modification Example 5) Next, the sheet-type RFID tag in Modification Example 5 of the present embodiment will be described with reference to FIG. 9. FIG. 9 is a diagram showing the sheet-type RFID tag in Modification Example 5. The sheet-type RFID tag 100D shown in FIG. 9 has a tag body 200D. The tag body 200D shown in FIG. 9 is a long sheet whose longitudinal direction (Y direction) is the long direction. In the tag body 200C, one end portion 206, the central portion 204, and the other end portion 208 are arranged in order from the upper side.

[0062] In the above Modification Example 4, the wireless tag circuit element 300 is arranged in approximately half of the area of the tag body 200C. On the other hand, in Modification Example 5, the wireless tag circuit element 300 is arranged in the area of one end portion 206 of the tag body 200D. In the above Modification Example 4, components such as the loop antenna portion 310 constituting the wireless tag circuit element 300 are arranged in the longitudinal direction (Y direction). On the other hand, in Modification Example 5, the components are arranged in the short-side direction (X direction). In Modification Example 5, similar to Modification Example 4 above, the tag body 200D is attached to an object (not shown) by a string 240 with its right side edge 202c facing upward (+Y direction).

[0063] Next, the 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 attached to an object (not shown). First, for example, grasp the other end portion 208 and pull it away from the object (apply a downward load F to the other end portion 208). As a result, the string 240 passed 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. Therefore, a shearing force by the string 240 is generated at the peripheral edge of the through-hole 250 (the portion where the string 240 abuts).

[0064] Next, if the other end portion 208 is further pulled away from the object, the peripheral edge of the through-hole 250 is damaged toward the position of the right side edge 202c (the edge located on the upper side shown in FIG. 9) by the shearing force of the string 240. Then, when the damaged portion reaches outside the region surrounded by the loop antenna portion 310, the loop antenna portion 310 is destroyed. When the loop antenna portion 310 is destroyed, the RFID tag 100D becomes dysfunctional. Therefore, after confirming that the loop antenna portion 310 is destroyed, the RFID tag 100B may be discarded.

[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.
