Description

[0001] This application claims priority to U.S. Provisional Application No. 63 / 581,462, filed September 8, 2023, entitled “RFID Label with Stitched Wire,” which is incorporated herein by reference in its entirety.

[0002] This disclosure generally relates to labels (or tags) associated with clothing. For example, this disclosure relates to radio frequency identification (RFID) tags with sewing threads and methods for manufacturing such RFID tags.

[0003] Description of prior art As more retailers implement RFID to improve inventory accuracy, reduce stockouts, and increase sales, they are exploring other ways to leverage RFID technology. Inventory accuracy also enables various omnichannel delivery models, which are typically implemented after inventory management. Retailers are also beginning to consider the possibility of using RFID tagging for loss prevention, eliminating the need for multiple tags per item (e.g., RF Electronic Article Surveillance (EAS), Acoustomagnetic (AM) EAS, and RFID). Additionally, common RFID tagging delivery formats, such as RFID hanging tags and RFID sewn-in tags, may not be ideal for loss prevention because they are easily removed by shoplifters. Therefore, advanced retailers may embed RFID tags into clothing. Embedded RFID tags may be more difficult for shoplifters to remove quickly in the store. Similarly, if retailers want to add more beneficial uses to RFID tagging, they can use clothing-integrated RFID tags to provide a frictionless experience for consumers. A frictionless experience could include the possibility of self-checkout kiosks (SCO) and mobile checkout (MCO).

[0004] However, improvements are needed to safety signs and / or labels. Summary of the Invention

[0048] It will be readily understood that the components of the aspects generally described herein and shown in the accompanying drawings can be arranged and designed in a wide variety of different configurations. Therefore, the following more detailed description of the aspects shown in the figures is not intended to limit the scope of this disclosure, but merely to illustrate the aspects. Although various aspects of these aspects are presented in the figures, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0049] The solutions of this invention may be embodied in other specific forms without departing from their spirit or essential characteristics. The described aspects should be considered in all respects as illustrative rather than restrictive. Therefore, the scope of this solution is indicated by the appended claims rather than this specific embodiment. All changes falling within the meaning and scope of equivalents of the claims are to be covered by the claims.

[0050] References to features, advantages, or similar language throughout this specification do not imply that all features and advantages achievable using the solutions of this invention should be included in or in any single aspect of the solutions of this invention. In fact, references to features and advantages should be understood to mean that a particular feature, advantage, or characteristic described in conjunction with one aspect is included in at least one aspect of the solutions of this invention. Therefore, discussions of features and advantages and similar language throughout this specification may (but are not necessarily required to) refer to the same aspect.

[0051] Furthermore, the described features, advantages, and characteristics of the solutions of this invention can be combined in one or more aspects in any suitable manner. Based on the description herein, those skilled in the art will recognize that the solutions of this invention can be practiced without one or more specific features or advantages in a particular aspect. In other instances, additional features and advantages may be recognized in certain aspects that may not be present in all aspects of the solutions of this invention.

[0052] Throughout this specification, references to “an aspect,” “aspect,” or similar language mean that a particular feature, structure, or characteristic described in connection with the indicated aspect is included in at least one aspect of this solution. Therefore, the phrases “in an aspect,” “on one side,” and similar language throughout this specification may, but not necessarily all, refer to the same aspect.

[0053] As used herein, unless the context clearly indicates otherwise, the singular forms “a / an” and “the” include the plural indicator. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. As used herein, the term “comprising” means “including, but not limited to”.

[0054] As mentioned above, the use of RFID tags in loss prevention, such as in electronic item monitoring systems, can be improved.

[0055] This disclosure includes RFID tagging integrated into product labels (such as brand labels) to form a product type called an RFID tag. In one embodiment, the RFID tag includes a brand label (or a textile label in the form of a textile sheet) formed of a fabric material, wherein conductive wires are sewn into the brand label. For example, the fabric material may include natural and / or synthetic fibers, including fibrous materials such as, but not limited to, polyester, nylon, silk, cotton, wool, linen, hemp, rayon, acrylic, and / or polyurethane (e.g., spandex, elastic fiber). Where the brand label includes a folded end, the sewing of the conductive wires on the non-folded portion of the brand label (and therefore the exposed or front portion of the brand label) is minimized and / or located in a relatively small portion of the area of ​​the non-folded portion, while the sewing on the folded end may be located over a relatively large portion of the area of ​​the folded portion. In some cases, the length of the conductive wires in the folded portion is greater than the length of the wires in the front or exposed portion of the brand label. In this way, the conductive wires may have sufficient length to form at least a portion of an antenna while minimizing the impact of the conductive wire sewing on the appearance of the brand label. An RFID loop (or RFID chip) is then attached next to the conductive wires to form an RFID transponder. In this way, the RFID ring (or RFID chip) can be separated from the conductive wires, such as in a location on the back of the brand label, to reduce exposure. Therefore, this aspect provides a visually appealing brand label with RFID functionality.

[0056] In another alternative or additional instance, RFID tags (or labels) may include visual information such as retail information and / or barcodes or QR codes. RFID tags may include RFID transponders (or RFID signage) integrated into branded labels. RFID tags can be visible signage located in an intuitive position within clothing. RFID tags can be variable information prints (VIPs) with retail information (e.g., brand information, size information, gender information, etc.) and, in some respects, may additionally include barcodes, such as, but not limited to, QR codes. Through the barcode, consumers can interact with the clothing. For example, consumers can sell used clothing (resale), order used clothing for repair, or even exchange clothing with other consumers. Most other signage types may not meet these types of use cases. These use cases can add significant value for retailers. From an operational perspective, the RFID tags described herein can be useful because they can replace non-RFID tags attached to items (such as clothing) and thus provide the desired RFID functionality. Furthermore, RFID tags do not add a new attachment process. For example, RFID tags can be attached using standard sewing processes. The RFID tags can enable RFID use cases in the supply chain and stores, including loss prevention. Therefore, current RFID tags have the potential to replace traditional EAS signs.

[0057] In some respects, the RFID tag essentially looks and feels like a non-RFID version of a branded label. Furthermore, the surface of the RFID tag can be printed with retail information and / or barcodes, and the associated inks used in such printing can be washable. For example, the inks and branded label materials can be selected so that any printing on the RFID tag (such as brand information and / or barcodes) can withstand dozens of washing cycles over the garment's lifespan. A non-limiting example printing method for applying ink to a branded label may include digital printing methods such as thermal transfer printing or inkjet printing.

[0058] Similarly, the electrical functionality of an RFID transponder integrated into an RFID tag may need to remain effective throughout the garment's lifespan. Therefore, the RFID transponder may need to be resistant to mechanical handling, high temperatures (e.g., ironing, steam finishing), washing, and time. Existing solutions struggle to meet these requirements simultaneously. For example, a soft and / or textile-like feel and texture are not suitable for durable products, as durability is typically achieved by packaging (or encapsulating) the electronic components of the RFID transponder within a protective layer. However, RFID tags as described herein are configured to address this dilemma by separating the large radiator (or antenna) portion of the transponder from the microchip portion containing the sensitive microchip of the transponder. The antenna portion of the transponder and the microchip portion can further communicate via inductive coupling technology. In one instance, the microchip can be attached to a relatively small loop antenna (compared to the size of a portion of an antenna formed by conductive wires). This loop inlay (e.g., microchip plus a miniature loop antenna) can then be placed next to (or on top of) the radiator antenna (e.g., stitched conductive wires). Thus, the relatively small loop inlay (e.g., microchip plus a small loop antenna) is more robust and better protected. Accordingly, due to the relatively small size of the ring inlay, the ring inlay does not make the entire brand label rigid and uncomfortable to wear. At the same time, the relatively large radiator portion (or large antenna portion) of the RFID transponder (e.g., stitched conductive wire) can be formed based on conductive wires integrated into the textile layer of the brand label.

[0059] To integrate the conductive wires of larger radiator components into the textile layer, RFID tags can be produced by stitching (or embroidering) the conductive wire pattern into the brand label material. An RFID loop (e.g., a microchip with a miniature loop antenna) can then be attached next to the wires (or the conductive wire pattern), thus forming a functional RFID transponder. The conductive wire pattern acts as the antenna for the RFID transponder. Because the stitching process creates a visible wire pattern on the top side of the textile tape, a special arrangement, as described herein, can be provided to achieve a visually appealing product.

[0060] In one aspect of this disclosure, the brand label (or RFID brand label) may have folded ends. For example, the two ends of the brand label may be folded before the brand label is attached to clothing.

[0061] On one hand, the exposed portion of the stitched conductive wire, which forms part of the antenna, can be located at the edge of the brand label, where the brand label remains unfolded. For example, by positioning the exposed portion of the stitched conductive wire at the edge of the brand label, the antenna may not be visually obtrusive because in many cases the edge of the brand label already includes some outline, and the brand label can ultimately be sewn onto the garment from the edge. Therefore, the conductive wire pattern can be relatively concealed.

[0062] On one hand, stitched conductive wire antennas can form patterns, such as meandering patterns, at both ends (e.g., folded ends) of the brand label. Thus, dipoles can be formed based on antennas positioned at the two folded ends. Since the ends are folded back, the stitched conductive wire pattern can be covered by the unfolded portion of the brand label and is not visible. The meandering pattern of the stitched conductive wire antenna enables RF design for RFID transponders. For example, the length of the dipole can be optimized for best RF functionality, and the inlay (or RFID ring) can be adjusted according to the use case and the RF frequency used.

[0063] On one hand, RFID rings (e.g., microchips attached to small conductive rings, such as etched loop antennas) can be applied to the back of a brand label. RFID rings can be manufactured on transparent materials. For example, RFID rings can be formed on a transparent fiber layer. Transparent materials minimize the visual impact of the RFID ring on the front of the brand label.

[0064] In one aspect of this disclosure, an RFID tag with an inductive coupling concept is provided. In the RFID tag, conductive wires are sewn (embroidered) into the fabric of the brand label. For the unfolded portion of the brand label, the wires travel along the edges of the brand label to achieve a visually appealing product, and more complex antenna shapes can be located at the folded ends (or folded portions) of the brand label. An RFID loop can then be located on the brand label to be inductively coupled to the sewn conductive wires.

[0065] For example, in one aspect of this disclosure, the wire pattern may not be arranged at the end fold. The back side of the brand label may include other metallic patterns (e.g., solid aluminum foil and / or conductive coating) and an RFID loop. The metallic patterns may serve as the antenna portion of an RFID transponder. Wires traveling along the edges of the brand label may be connected to these conductive elements.

[0066] On one hand, conductive wire patterns can be arranged at the end folds and act as the antenna portion of the RFID transponder. On the other hand, the back side of the unfolded portion of the brand label may include other metallic patterns (e.g., solid aluminum foil and / or conductive coating) and an RFID loop. Wires traveling along the edges of the brand label can be connected to these conductive elements.

[0067] Therefore, the RFID tag provides RFID functionality in the brand label.

[0068] refer to Figures 1A to 1F An example of an RFID tag (or label) 100 includes an antenna (or conductive wire pattern) 104 formed of conductive wires stitched into a sheet of material 101 (such as fabric) forming the tag 100, and inductively coupled to an RF chip (or RFID ring) 102 positioned on the back side 100B of the tag 100. The antenna 104 includes an exposed portion (or third portion) 105 of the stitched conductive wires on the front side 100A of the tag 100, and corresponding first and second non-exposed portions (or first and second portions) 110 and 112 on the folded ends (or folded ends) 114 and 116 of the tag 100. In the front side of the unfolded portion 118 of the tag 100, the exposed portion 105 of the conductive wires forming the antenna 104 may be stitched across the front side 100A of the tag 100, such as adjacent to a first edge 106 of the tag 100, where the first edge 106 is opposite a second edge 108. However, it should be understood that the exposed portion 105 of the antenna 104 stitched to the front side of the tag 100 may be stitched across any part or area of ​​the front side. In some cases, the first edge 106 of the tag 100 may have a different texture, such that the stitched conductive wires of the exposed portion 105 of the antenna 104 may be less visible compared to stitching across other areas of the front side. For example, the tag 100 may be stitched around edges (e.g., 106 and 108), such that the stitched conductive wires of the exposed portion 105 of the antenna 104 may blend into the stitching at the edges. The non-exposed portions 110 and 112 of the antenna 104 may include a first pattern 111 and a second pattern 113 across the area of ​​the folded ends 114 and 116 of the tag 100, which may be a matched pattern or a non-matched pattern. The first pattern 111 and the second pattern 113 may have a shape that covers or extends across a large portion of the area of ​​the folded ends 114 and 116, for example, to provide a configurable antenna length. Figure 1BThe first pattern 111 and the second pattern 113 are shown to have meandering contours. However, the first pattern 111 and the second pattern 113 may have any other suitable contours, such that the antenna 104 can be tuned to receive and / or transmit signals at a configurable frequency or frequency range. Additionally, the configuration of the first pattern 111 and the second pattern 113 may be designed to provide the antenna 104 with sufficient characteristics for RF communication when coupled to the RFID ring 102. The first pattern 111 and the second pattern 113 may be located behind the folded flaps (or folded ends) 114 and 116 of the tag 100, respectively. Therefore, the first pattern 111 and the second pattern 113 may not be visible when the tag 100 is attached to an item (such as clothing). The RFID ring 102 may be made using a transparent substrate, so the RFID ring 102 may be less visible when attached to the tag 100. On the other hand, the RFID ring 102 is attached to the back side 100B of the tag 100, making the RFID ring 102 less visible when the tag 100 is attached to an item (such as clothing).

[0069] Antenna 104 can be a continuously stitched conductive wire or a separately stitched conductive wire, wherein the exposed portion 105 is connected to the non-exposed portions 110 and 112 of antenna 104. Antenna 104 can be coupled to RFID loop 102. In one example, a third portion 105 of antenna 104 can be spaced apart but inductively coupled to RFID loop 102. In one example, the third portion 105 of antenna 104 can be connected to RFID loop 102 to form a connection circuit system. An RFID transponder can be formed based on the coupling of antenna 104 and RFID loop 102. The RFID transponder can communicate wirelessly with an RFID reader (not shown). The RFID reader can retrieve information stored in the RFID transponder and further provide the obtained information to a computer database. The obtained information can be further verified / analyzed based on the computer database. Therefore, RFID tag 100 can be applied to (i) inventory management and loss prevention for easy e-commerce delivery and (ii) self-checkout and mobile checkout. The RFID transponder can also provide a confidentiality mode and authentication functionality. For example, by retrieving product information stored in an RFID transponder, customers can determine the production and / or purchase time and location of clothing. In secure mode, an RFID transponder can only be read by an RFID reader from a very short distance (e.g., a few centimeters or tens of centimeters), or only by someone who knows the password.

[0070] In some respects, the RFID tag 100 may additionally include a near field communication (NFC) chip and coil loop electrically connected to the antenna 104, thereby providing the RFID tag 100 with NFC communication capabilities.

[0071] like Figure 1A and Figure 1BAs shown, the RFID tag 100 may include an unfolded portion 118 and two folded ends (or a first end portion and a second end portion) 114 and 116. The unfolded portion 118 is arranged between the two folded ends 114 and 116. In one example, the unfolded portion 118 may be, but is not limited to, a rectangle, triangle, square, ellipse, or circle. Figure 1A and Figure 1B In the example, the expanded portion 118 has a rectangular shape.

[0072] It should be noted that Figure 1A and Figure 1B These are merely examples. For instance, the conductive wires forming the third portion 105 of the antenna 104 may be stitched together and extended along another portion (such as, but not limited to, the center) of the unfolded portion 118 of the tag 100. Additionally, the RFID loop 102 may be positioned at any suitable location on the unfolded portion (or middle portion) 118 of the tag 100.

[0073] For the sake of simplicity and clarity, Figure 1A Visual information, such as brand information (e.g., brand logo) and / or barcodes, such as, but not limited to, QR codes, is not shown in the image. Figure 7 and Figure 8 Examples are provided. In one example, printed information (such as a barcode) may be printed on the front side of label 100, such as on the front side of the unfolded portion 118. The barcode can provide functionality associated with mobile checkout, consumer engagement, or act as a digital product passport.

[0074] For more specific reference Figure 1C and Figure 1D The conductive wire pattern (or antenna) 104 includes conductive wires that extend through the middle portion 108 of the RF tag 100 and are arranged in a meandering pattern in the first end portion 114 and the second end portion 116 of the RF tag 100. Figure 1C and Figure 1D In this example, the conductive wire pattern 104 is arranged along the first edge 106 of the middle portion 118 of the RFID tag 100. An RF chip (or RF ring) 102 is arranged adjacent to the first edge 106 of the middle portion 118 of the RFID tag 100. Additionally, the RFID tag 100 includes a fold line 120, which is an imaginary line along which the ends of the RFID tag 100 (e.g., a first end portion and a second end portion) are folded before the RFID tag 100 is attached to an object (such as clothing).

[0075] For more specific reference Figure 1E and Figure 1F The first end portion 114 and the second portion 116 are folded along the fold line 120 toward the middle portion 118 of the label 100.

[0076] refer to Figures 2A to 2F Another example of the RFID tag 200 includes a conductive wire pattern 204, which has, in the folded first end portion 214 and second end portion 216, a conductive wire pattern having, respectively, an edge 210A and 212A between the third portion 205 and the edges 210A and 212A of the first portion 210 and the second portion 212 (see [link to relevant documentation]). Figures 2C to 2E The steps of the RFID tag 200 allow for improved wireless signal transmission and reception capabilities. Additionally, in some aspects, the conductive wire pattern 204 may be spaced apart from the edges of the RFID tag 200, which provides an area for attachment mechanisms (such as, but not limited to, sewing, adhesives, ultrasonic welding) to attach the RFID tag 200 to an object without potentially damaging the conductive wire pattern 204. It should be understood that the RFID tag 200 and its components may be similar to the RFID tag 100 and its components.

[0077] For more specific reference Figure 2A and Figure 2B The RFID tag 200 includes a material sheet 201, a conductive wire pattern 204, and an RF chip 202. The material sheet 201, or textile sheet, may be made of a fabric material. The fabric material may include natural and / or synthetic fibers, including fibrous materials such as, but not limited to, polyester, nylon, silk, cotton, wool, flax, hemp, rayon, acrylic, and / or polyurethane (e.g., spandex, elastic fibers). The textile sheet 201 includes a first end portion 214, a second end portion 216 opposite to the first end portion 214, and an intermediate portion 218 disposed between the first end portion 214 and the second end portion 216. The conductive wire pattern 204 includes a first portion 210 fixed to the first end portion 214 of the textile sheet, a second portion 212 fixed to the second end portion 216 of the textile sheet, and a third portion 205 fixed to the intermediate portion 218 of the textile sheet and coupled (e.g., connected to) the first portion 210 and the second portion 212 of the conductive wire pattern 204. An RF chip 202 is attached to the middle portion 218 of a textile sheet. The RF chip 202 is further positioned on the first (or back) side 200B of the textile sheet and coupled to the third portion 205 of the conductive wire pattern 204. The first end portion 214 and the second end portion 216 of the textile sheet are folded toward the first side 200B of the textile sheet, such that the first portion 210 and the second portion 212 of the conductive wire pattern 204 are covered by the middle portion 218 of the textile sheet.

[0078] Regarding the stepped configuration of the conductive wire pattern 204, a first portion 210 of the conductive wire pattern 204 is positioned adjacent to a first edge 206 of the RFID tag 100 at a first distance T1. A second portion 212 of the conductive wire pattern 204 is positioned adjacent to the first edge 206 of the RFID tag 100 at a first distance T1. A third portion 205 of the conductive wire pattern 204 is arranged to extend through the middle portion 218 of the textile sheet and is positioned adjacent to the first edge 206 of the RFID tag 100 at a second distance T2. The second distance T2 is smaller than the first distance T1, thereby defining a gap ΔS that separates adjacent portions of the conductive wire pattern 204 when the first end portion 214 and the second end portion 216 are folded over the middle portion 218. The gap ΔS helps to isolate each adjacent, overlapping portion of the conductive wire pattern 204, thereby increasing the effective length of the wire and thus improving radio signal transmission and reception.

[0079] Still referencing Figure 2A and Figure 2B The first portion 210 of the conductive wire pattern 204 is positioned adjacent to the second edge 208 of the RFID tag 200 at a third distance T3. The second portion 212 of the conductive wire pattern 204 is positioned adjacent to the second edge 208 of the RFID tag 200 at a third distance T3. In one example, the first portion 210 of the conductive wire pattern 204 is positioned adjacent to the fold line 220 at a fourth distance T4, and the second portion 212 of the conductive wire pattern 204 is positioned adjacent to the fold line 222 at a fourth distance T4. In one example, the fold lines 220 and 222 serve as the edges of the middle portion 218 of the textile sheet, such that the width of the middle portion 218 of the textile sheet is defined by the fold lines 220 and 222.

[0080] For more specific reference Figure 2C and Figure 2D The second distance T2 is less than the first distance T1. In one example, distances T1, T2, T3, and T4 are configured to provide space for a fixing mechanism, as described above, to fix the RFID tag 200 to clothing or other objects in a manner that avoids interfering with the conductive wire pattern 204.

[0081] For more specific reference Figure 2E When the first end portion 214 and the second end portion 216 of the textile sheet are folded toward the first side (or back side) 200B of the textile sheet, (i) the gap ΔS between the edge 210A of the first portion 210 of the conductive wire pattern 204 adjacent to the first edge 206 of the textile sheet and (ii) the third portion 205 of the conductive wire pattern 204 is, for example, in the range of 0.05 mm to 5 mm. In other words, the difference between T1 and T2 is in the range of 0.05 mm to 5 mm.

[0082] refer to Figure 3 Various examples include gaps ΔS of different sizes between the edge 210A of the first portion 210 of the conductive wire pattern 204 and the third portion 205 of the conductive wire pattern 204. For example, the gap ΔS is 0.1 mm in the folded state 302, 1 mm in the folded state 304, and 4 mm in the folded state 306. It should be noted that the gap ΔS between the edge of the second portion 212 of the conductive wire pattern 204 and the third portion 205 of the conductive wire pattern 204 can also be in the range of 0.05 mm to 5 mm.

[0083] On one hand, the RF performance of an RFID tag is characterized by the tag's forward power-on (POTF) metric. The POTF metric characterizes the sensitivity of the RFID tag and indicates the minimum RF power required to successfully activate it. In one example, the RFID tag uses a minimum output RF power of -15 dBm. On the other hand, the POTF can degrade when the RFID tag is folded. For example, a 3 dBm decrease in POTF output power can be observed when the RFID tag is folded compared to when it is unfolded.

[0084] On the one hand, the performance of POTF in the RFID band depends on the gap distance between adjacent and / or overlapping portions of the conductive wire pattern in the top layer (e.g., the middle portion) of the RFID tag and the folded wings (first end portion and second end portion). Figure 3 The gap ΔS is shown in the figure. In one example, as the folding distance increases, the performance of the folded antenna tends to be similar to that in the unfolded state.

[0085] refer to Figure 4A and Figure 4B In an alternative or additional aspect, the conductive wire pattern 404 may be spaced apart from all edges of the RFID tag 200, which can provide multiple distinct areas for attachment mechanisms (such as, but not limited to, sewing, adhesives, ultrasonic welding) to attach the RFID tag 400 to an object without potentially damaging the conductive wire pattern 204. It should be understood that the RFID tag 400 and its components may be similar to those of the RFID tag 100 and / or the RFID tag 200 and its components. More specifically, in Figure 4A and Figure 4BIn this RFID tag 400, a textile sheet 401, a conductive wire pattern 404, and an RF chip 402 are included. The textile sheet 401 includes a first end portion 414, a second end portion 416 opposite to the first end portion 414, and an intermediate portion 418 disposed between the first end portion 414 and the second end portion 416. The conductive wire pattern 404 includes a first portion 410 fixed to the first end portion 414 of the textile sheet, a second portion 412 fixed to the second end portion 416 of the textile sheet, and a third portion 405 fixed to the intermediate portion 418 of the textile sheet. The third portion 405 of the conductive wire pattern 404 extends through the intermediate portion 418 of the textile sheet and connects to the first portion 410 and the second portion 412 of the conductive wire pattern 404. In one aspect, compared to the RFID tag 200, no gap is formed between the edges 410A and 412A of the first portion 410 and the second portion 412 of the conductive wire pattern 404 and the third portion 405 of the conductive wire pattern 404.

[0086] Still referencing Figure 4A and Figure 4B The RF chip 402 is attached (or fixed) to the middle portion 418 of the textile sheet. The RF chip 418 is further positioned on the first (or back) side 400B of the textile sheet and coupled to the third portion 405 of the conductive wire pattern 404. Figure 4A As shown, the first end portion 414 and the second end portion 416 of the textile sheet can be folded toward the first surface 400B of the textile sheet, such that the first portion 410 and the second portion 412 of the conductive wire pattern 404 are covered by the middle portion 418 of the textile sheet.

[0087] On one hand, the first end portion 414 has a width W1, the middle portion 418 has a width W2, and the second end portion 416 has a width W3. In one instance, W1 equals W3. In another instance, W1 and W3 are different. For example, W1 is greater than W3. W1, W2, and W3 can be any suitable numbers. In one instance, W1 equals 14 mm, W2 equals 55 mm, and W3 equals 11 mm.

[0088] In one aspect, the first portion 410 of the conductive wire pattern 404 has a distance W4 to the first fold line 420 (or the first edge of the intermediate portion 418). In another aspect, the second portion 412 of the conductive wire pattern 404 has a distance W5 to the second fold line 422 of the conductive wire pattern 404 (or the second edge of the intermediate portion 418). In one example, W4 is equal to W5. In another example, W4 and W5 are different. W4 and W5 can be any suitable numbers. In one example, W4 and W5 are equal to 3 mm.

[0089] In one aspect, the first portion 410, the second portion 412, and the third portion 405 of the conductive wire pattern 404 have a distance W7 to the first edge 406 of the textile sheet. In another aspect, the first portion 410, the third portion 405, and the second portion 412 of the conductive wire pattern 404 have a distance W6 to the second edge 408 of the textile sheet. In one example, W6 is equal to W7. In another example, W6 is different from W7. W6 and W7 can be any suitable numbers. In one example, W6 and W7 are equal to 3 mm.

[0090] refer to Figure 5 Instances of RF chip (or RF ring) 500 may have the same or similar configuration as RF chip / ring 102 or RF chip / ring 202. For example... Figure 5 As shown, the RF chip / ring 500 includes a substrate 502, a conductive wire loop 504 positioned on the substrate 502, and an RFID microchip 506. The substrate may be white or transparent. The conductive wire loop 504 is an open loop including a gap ΔW. In one aspect, the RFID microchip 506 is positioned on the conductive wire loop 504 and arranged across the gap ΔW of the conductive wire loop 504. In one example, the conductive wire loop 504 is configured to act as a miniature loop antenna and interact with (or couple to) a conductive wire pattern (e.g., 104, 204, or 404). The RFID microchip 506 is configured to store information, such as brand or retail information for clothing or objects, and other unique information for identifying the RFID microchip 506. In one aspect, the substrate 502 may include an adhesive layer configured to form a mechanical bond between the RF chip / ring 500 and the back side of a textile sheet (e.g., 100B or 200B). In one aspect, the RF chip / ring 500 may include a protective layer (not shown) positioned over the RFID microchip 506 and the conductive wire ring 504. The protective layer may be transparent or white.

[0091] refer to Figure 6 Another example of an RFID tag (or label) 600 includes a dielectric layer 602 to improve one or more wireless signal transmission and / or reception characteristics of the RFID tag 600. It should be understood that the RFID tag 600 and its components may be similar to RFID tag 100 and / or RFID tag 200 and / or RFID tag 400 and their components. When the first end portion 614 and the second end portion 616 of the tag 600 are folded toward the first side (or back side) 600B opposite the second side (or front side) 600A of the tag 600, the dielectric layer 602 is positioned between (i) the middle portion 618 of the tag 600 and (ii) the first end portion 614 and the second end portion 616 of the tag 600. As mentioned above, the POTF of the RFID tag may degrade when it is folded. The dielectric layer 602 has a thickness...t This arrangement, positioned between the first / second end portion and the middle portion of the RFID tag 600, spaced the folded layer, which reduces POTF degradation. The dielectric layer 602 can be made of any suitable dielectric material and has any suitable thickness configured to provide one or more predetermined performance characteristics to the RFID tag 600.

[0092] refer to Figure 7 Tag 702 may be identical or similar to tag 100 and / or RFID tag 200 and / or RFID tag 400 and / or RFID tag 400 and their components, including visual information such as retail information. For example, tag 702 may have an unfolded portion 710 positioned between two end folds 706 and 708. Tag 702 may be made of different materials or have different colors. Tag 702 may have visual information 712 printed, sewn, or otherwise positioned on the front side of tag 702. Visual information 712 may include, but is not limited to, retail information and / or barcodes. Retail information may be any information associated with the corresponding garment to which tag 702 is attached, such as brand name (or brand logo) (e.g., denim), gender type of the garment (e.g., women's), and size (e.g., XS and / or 24). In one aspect, a barcode (such as a QR code (not shown)) may be printed on the front side of the branded label.

[0093] refer to Figure 8 An RFID tag (or label) 800 is attached to garment 802, such as, but not limited to, the inside of the garment's collar. The RFID tag 800 may be the same as or similar to any of RFID tags 100, 200, 400, 600, and / or 700. In some aspects, the RFID tag 800 may be attached at the source (e.g., the manufacturing location) via an attachment mechanism 804. In one example, the attachment mechanism 804 includes sewing (e.g., stitching), bonding, ultrasonic welding, etc. The RFID tag 800 may be washable. For example, the RFID tag 800 may have two washability levels: up to the point of sale, e.g., one cycle, and garment lifespan, e.g., approximately 80 cycles.

[0094] Still referencing Figure 8Retail information 806 for the garment is printed on the front side of the brand label 800. An RFID transponder may be placed on the back side of the label 800. The RFID tag can be used for (i) inventory management and loss prevention for easy e-commerce delivery and (i) self-checkout and mobile checkout. The label 800 may provide consumer engagement via a printed QR code (not shown). The RFID transponder may also provide confidentiality modes and authentication capabilities. For example, by retrieving product information (e.g., ID information) stored in the RFID transponder, a customer can determine the production and purchase time and place of the garment. The RFID tag can provide product information that complies with future digital product passport regulations. The product information provided by the RFID tag enables recurring use cases (e.g., buyback, lease, and repair). In some respects, the RFID tag may be attached at the source (e.g., manufacturing location). The RFID tag may have a textile feel and texture. By integrating the functionality of RFID tagging and branding labels, the RFID tag can eliminate the need for additional RFID tagging and replace branding labels. Therefore, the RFID tag can be an “all-in-one” RFID tagging solution, enabling use cases from source marking to the supply chain to storage and the end of the garment's lifecycle. In one example, QR codes can be printed onto RFID tags. Permanent QR codes can facilitate mobile checkout and consumer engagement, and act as digital product passports.

[0095] refer to Figure 9 According to one aspect of this disclosure, a method 900 for generating RFID tags in clothing can be implemented. The process begins at S901 and proceeds to S910.

[0096] In S910, a conductive wire pattern is fixed in a textile sheet. The textile sheet includes a first end portion, a second end portion opposite to the first end portion, and an intermediate portion disposed between the first end portion and the second end portion. The conductive wire pattern includes a first portion fixed to the first end portion of the textile sheet, a second portion fixed to the second end portion of the textile sheet, and a third portion fixed to the intermediate portion of the textile sheet and coupled to the first and second portions of the conductive wire pattern. In one example, the conductive wire pattern sewn into the textile sheet includes an exposed portion 105 sewn into the intermediate portion (or folded portion) 118 of the label 100, and non-exposed portions 110, 112 sewn into the first end portion (or first folded end) 114 and the second end portion (or second folded end) 116 of the label 100, respectively.

[0097] In S920, a radio frequency (RF) chip is attached to the middle portion of the textile sheet. The RF chip is positioned on a first surface of the textile sheet and coupled to a third portion of a conductive wire pattern. In one example, the RFID chip includes an RFID ring (or RF chip) 102 attached to tag 100.

[0098] In S930, the first and second end portions of the textile sheet are folded toward the first surface of the textile sheet, such that the first and second portions of the conductive wire pattern are covered by the middle portion of the textile sheet. An exemplary aspect may be... Figure 1A and Figure 1B As shown, the first end portion 114 and the second end portion 116 are folded toward the back side of the label 100.

[0099] In S940, a folded textile sheet is attached to the garment such that (i) the first and second portions of the conductive wire pattern and (ii) the RF chip are covered by the middle portion of the textile sheet. Exemplary aspects may be... Figure 8 As shown, the first and second portions of the conductive wire pattern and the RF chip are covered by the middle portion of the tag 800. Therefore, the RFID transponder, including the conductive wire pattern (e.g., antenna 104) and the RF chip, can be concealed by the textile sheet.

[0100] In one aspect, a first portion of the conductive wire pattern is positioned adjacent to a first edge of a first end portion at a first distance. A second portion of the conductive wire pattern is positioned adjacent to a first edge of a second end portion at a first distance. A third portion of the conductive wire pattern is arranged to extend through the middle portion of the textile sheet and positioned adjacent to a first edge of the middle portion at a second distance, wherein the second distance is smaller than the first distance.

[0101] In one aspect, the RF chip includes a substrate, a conductive wire loop, and a chip. The substrate is white, and the conductive wire loop is positioned on the substrate, wherein the conductive wire loop is an open loop including gaps. The chip is positioned on the conductive wire loop and arranged across the gaps in the conductive wire loop.

[0102] In one aspect, in this method, visual information is printed on a second surface of a textile sheet and arranged in the middle portion of the textile sheet, wherein the second surface is opposite to the first surface.

[0103] On one hand, when the first end portion and the second end portion of the textile sheet are folded toward the first surface of the textile sheet, (i) the gap between the edge of the first portion of the conductive wire pattern adjacent to the first edge of the first end portion of the textile sheet and (ii) the third portion of the conductive wire pattern is in the range of 0.1 mm to 5 mm.

[0104] Then, the process enters S999 and ends.

[0105] Process 900 can be adjusted as appropriate. Steps in process 900 can be modified and / or omitted. Additional steps can be added. Any suitable implementation order can be used.

[0106] The RFID tags described in this article can be used under various conditions.

[0107] Figure 10 Table 500 shows a ladder of RFID use cases. (For example...) Figure 10 As shown, in 2010, RFID was introduced into Supply Chain Management (SCM). For example, RFID can be used for raw material traceability, supply chain management, e-commerce shipping, inventory management, and point of sale. Related retail themes may include the circular economy, omnichannel, and omnichannel product supply. In 2020, RFID was widely used in stores. For example, RFID can be applied to loss prevention, self-checkout, mobile checkout, returns management, and consumer engagement. Related retail themes may include frictionless retail. In 2023, RFID can be further used in after-sales service. For example, RFID can be used for digital product passports, leasing, resale, recycling, and authentication. Related retail themes may include the circular economy.

[0108] Figure 11 Table 1100 illustrates the use case suitability of different RFID tag types. Table 1100 presents how different RFID tag types are suitable for various RFID use cases. Based on Table 1100, integrated tagging is best suited for new use cases related to loss prevention and synchronized frictionless retail, as well as use cases related to the circular economy.

[0109] MCOs require consumers to connect clothing to their mobile devices. QR codes can be a convenient way for consumers to connect with clothing. QR codes can be printed onto integrated clothing labels, making them available for managing the synchronization of Global Trade Item Serial Numbers (SGTINs). SGTINs can be programmed into a microchip in a UHF RFID inlay within the label, and can further be printed onto a QR code on the same label surface. One advantageous way to combine QR codes and SGTINs is to integrate RFID functionality and QR codes into the clothing's brand label. Thus, the clothing's brand label can be created as an RFID tag. By using RFID tags, there is no need to attach additional tags to clothing, and the corresponding additional tag attachment process can be avoided during clothing production. In fact, the implementation of RFID tags can provide a long list of RFID use cases, including supply chain management, inventory management, point of sale (POS), loss prevention, SCO, MCO, returns management, consumer engagement, digital product passports (DPP), and various circular economy use cases such as leasing, resale, and recycling.
