Description

Technical Field

[0001] This invention relates to the method of using RFID tags and their structure. Background Technology

[0002] The Internet of Things (IoT) is a network that connects objects to the internet through information sensing devices such as RFID, infrared sensors, GPS, and laser scanners, according to agreed-upon protocols. This enables information exchange and communication, achieving intelligent identification, location, tracking, monitoring, and management of objects. It consists of three layers: the perception layer, the network layer, and the application layer. The perception layer is the "nerve ending" of the IoT system, utilizing sensing nodes distributed across various IoT objects to collect object information; it is the source and foundation of information for the IoT system.

[0003] In existing IoT sensing layer applications, Radio Frequency Identification (RFID) technology plays a crucial role. RFID is a simple wireless system consisting of a reader and tags. The tags need to be attached to IoT objects to identify them. In practical applications, tags come in various shapes and types, and based on their packaging, they can be categorized as card tags, linear tags, paper tags, glass tube tags, button tags, nail tags, and special-purpose irregularly shaped tags, etc. In summary, existing identification methods fall into two categories: external pasting, hanging, and wearing, and internal embedding. However, this approach presents several problems.

[0004] A1. The practical application needs of using IoT technology for intelligent identification, positioning, tracking, monitoring and management are mainly concentrated in large-scale socialized production, warehousing, logistics and sales activities. These activities account for a limited proportion of the life cycle of the identified items, and the actual usage cycle of the tags is very short. They are used in stages. Regardless of whether they are externally pasted, hung, worn or embedded, they are mostly used once, resulting in cost and resource waste.

[0005] A2. The built-in embedding method has many limitations, and many IoT objects cannot, are not suitable, or are inconvenient to use the embedded identification method;

[0006] A3. When using external adhesive, hanging, or wearing methods, the item is attached, hung, or worn on its surface or packaging, making it easy to peel off or damage.

[0007] A4. Due to cost and the limitations of the two existing labeling methods, the label structure tends to be simple, the function is limited, and the application scope is restricted.

[0008] The existence of the above problems has affected and restricted the application and development of radio frequency identification (RFID) and Internet of Things (IoT) technologies. Summary of the Invention

[0009] In this article, the term "intra-tag structure" should be understood as: the functional structure by which the RFID tag and the reader achieve spatial coupling and / or energy transfer of RFID signals, and data storage and / or exchange.

[0010] In this article, the term "external structure of the tag" should be understood as: the functional structure required to realize the RFID tag identification method, in addition to the internal structure of the tag.

[0011] In this article, the terms "container tag", "integrated container tag", or "container tag" should all be understood as follows: the internal structure of the RFID tag is integrated with the container and cannot be separated. The container is the external structural form of the RFID tag and is the functional structure that enables the tag to identify itself.

[0012] In this article, the terms "container label locking" or "locked label" should be understood as: the container and label are integrated, and the labeled item inside the label container cannot be removed from the label container as a whole or intact without unlocking or damaging the label container.

[0013] In this article, the terms "controlled opening and closing" or "controlled opening and closing" should be understood as follows: the container and the tag are integrated, the system judges the request to unbind the tagged item or unlock it, grants permission and / or automatically unlocks and / or records legitimate requests, and the system may alarm and / or record illegal opening or damage to the tag container.

[0014] This invention addresses the aforementioned problems in the application of radio frequency identification (RFID) technology for object identification, and proposes a solution to overcome the following issues: short usage cycles and cost and resource waste caused by single-use of RFID tags in the identification application process; the inability, unsuitability, or inconvenience of embedding tags into many items; the ease with which external methods such as pasting, hanging, or wearing can be peeled off or damaged, leading to identification errors or failures; and the limited functionality and application scope of tags.

[0015] This invention innovates a radio frequency identification (RFID) tag marking method, belonging to a third type of marking method, different from the two previous types of marking methods: external pasting, hanging, wearing, and internal embedding. It seems simple, but its application effect is unexpected. Its feature is that the marked item is placed inside the tag and wrapped by the tag. The tag has a container with opening and closing functions, hence it is called an inverted internal marking method. This marking method is neither an external pasting, hanging, or wearing of the RFID tag on the outside of the marked item, nor is it internally embedded in the marked item. Instead, the marked item is placed under the tag.

[0016] This invention presents an innovative inverted embedded identification method for radio frequency identification tags. While seemingly simple, its application results are surprisingly effective. The method is characterized by including, but is not limited to, the following steps and sequence:

[0017] S11. Place the labeled item into the label container and lock the container label;

[0018] S12. Write the relevant information of the identified item into the label and / or system;

[0019] S13. The label is bound to the item being identified;

[0020] S14. Determine whether to unbind the marked item and / or unlock the request;

[0021] S15. Grant a valid request to unbind and / or automatically unlock and / or record, open the tag container, and remove the tagged object item;

[0022] S16. Unauthorized opening of the container label or damage to the container body may trigger an alarm and / or record.

[0023] An RFID container tag structure for implementing the aforementioned RFID tag inverted internal identification method is characterized by: including at least one tag internal structure 9, which is encapsulated together with the container body to form an integrated container and tag, wherein the container is the tag and the tag is the container; the tag container is provided with a locking mechanism 8, which can be opened and / or locked in a controlled manner; the tag container body may be covered with a mesh conductor, and unauthorized opening or damage to the container body or cutting of the conductor can trigger an alarm and / or record.

[0024] Furthermore, according to the aforementioned RFID tag inverted identification method or RFID container tag structure, the tag container body is characterized by: a display module being provided, configured with, but not limited to, an EPD, LCD, or OLED display screen 10, to actively and / or passively display information about the identified items inside the tag container.

[0025] Furthermore, according to the aforementioned RFID tag inverted identification method or RFID container tag structure, the characteristic is that: the identifiable object is placed inside the container tag, and the identifiable object may or may not be identifiable through the tag container, thus meeting the needs of different identification application scenarios.

[0026] Furthermore, according to the aforementioned RFID tag inverted identification method or RFID container tag structure, the tag container body is characterized in that: the tag container body includes, but is not limited to, a rigid cube, cylinder, or irregularly shaped box, or a flexible bag.

[0027] Furthermore, according to the aforementioned RFID tag inverted identification method or RFID container tag structure, the characteristic is that: when locking and / or unlocking the container tag, the time and / or location and / or other real-time status data information related to the switch operation are sent to cloud storage and / or blockchain storage through the reader or mobile phone that performs the switch operation, ensuring that the relevant data information is authentic, reliable and traceable.

[0028] To achieve the effect of internally identifying items using the rigid cubic box container label of this invention, this invention also provides two box label structure schemes.

[0029] Option 1: A label structure for a rigid cubic box container, such as... Figure 2 As shown, the feature is that: of the six faces of the cube box label 1, 2, 3, 4, 5, and 6, faces 3, 4, 5, and 6 are fixedly connected to each other, while faces 1 and 2, and faces 2 and 3 are movably connected. A limiting structure 7 is provided at the joint between faces 1 and 2 and faces 4, 5, and 6 when the box is locked. A locking mechanism 8 is provided at the joint between faces 1 and 4. The angle between the fixedly connected faces 4, 5, and 6 and face 3 is greater than 90 degrees, facilitating the stacking and storage of the box labels after the free ends of faces 1 and 2 are opened. An internal structure 9 and a display screen 10 are located within faces 1, 4, or other faces.

[0030] Option 2: A rigid cylindrical box container label structure, such as... Figure 3 As shown, the features are as follows: of the three surfaces of the cylindrical box label, namely the arc surface 21, surface 22, and surface 23, the two end surfaces of surface 22 and surface 23 are fixedly connected to the fixed end 21B of the arc surface 21; a limit structure 7 is provided at the joint between the free surface of the arc surface 21 and the two end surfaces of surface 22 and surface 23 when the box is locked; a locking mechanism 8 is provided at the joint between the free end 21A and the fixed end 21B of the arc surface 21; the angle between the two end surfaces of the cylindrical box label surface 22 and surface 23 and the starting connection point 21C of the fixed end 21B of the arc surface 21 is greater than 90 degrees, which facilitates the stacking and storage of the box label after the free surface of the arc surface 21 is opened; the internal structure 9 and the display screen 10 are disposed within the arc surface 21, or surface 22, or surface 23.

[0031] To achieve the effect of internal labeling of items on the flexible bag container of the present invention, the present invention also provides three locking bag opening solutions.

[0032] Solution 3: A flexible bag label locking structure, characterized in that: the bag opening is connected to a rigid material frame, wherein frames 31, 32, 33, and 34 are as follows: Figure 4 The connected parts form a rectangular quadrilateral bag opening; the borders 31 and 32, and 33 and 34 are respectively in opposite arc shapes, so that they are straightened by deformation when the bag opening is locked, generating a deformation tension. When the bag is opened, the deformation tension of the borders will automatically open the bag opening; when the bag opening is locked, the rigid border of the bag opening expands outward along the diagonal, so that the bag opening changes from four sides to two sides and is joined together, or one side of the border is embedded in the groove 11 of the other side of the border. A locking mechanism 8 is provided on the corresponding joined borders so that the bag opening is clamped and locked by the borders; the label internal structure 9 and the display screen 10 are set on either border.

[0033] Solution 4: A flexible bag label locking structure, characterized in that: the bag opening is connected to a rigid material frame, wherein frames 41, 42, 43, 44, 45, and 46 are as follows: Figure 5 The hexagonal shape is formed by connecting the borders 43 and 44, 45 and 46, and 41 and 42, which are in opposite directions. When the bag is closed, the borders are deformed and straightened, generating a deformation tension. When the bag is opened, the deformation tension of the borders automatically opens the bag. When the bag is closed, the connection points of borders 43 and 44, and borders 45 and 46, move towards the center of the bag opening. Borders 41 and 42 move closer to each other, folding and embedding borders 43, 44, 45, and 46 into the grooves 11 of borders 41 and 42 until borders 41 and 42 are brought together. A locking mechanism 8 is provided on borders 41 and 42 to clamp and lock the bag opening. The label internal structure 9 and the display screen 10 are set on borders 41 or 42.

[0034] Option 5: A flexible bag label locking structure, such as... Figure 6 As shown, the main features are: the bag opening is provided with a sleeve 52 that surrounds the bag opening and wraps the bag-tying rope 53. The two ends of the sleeve 52 are connected to the locking rope box 51. When the bag opening is locked, the bag-tying rope 53 that passes out of the locking rope box 51 is pulled, so that the bag opening is continuously narrowed until the bag opening is closed and the locking control mechanism 8 inside the locking rope box 51 is triggered to lock the bag-tying rope 53; the label internal structure 9 and the display screen 10 are set on the locking rope box 51.

[0035] A retail method utilizing inverted RFID tag identification and container label structure, characterized by the following steps:

[0036] S21. Retail goods are locked in container labels by the inverted internal labeling according to the quantity or number of items sold, so that customers cannot directly touch the goods when selecting them, thus reducing damage and contamination to the goods.

[0037] S22. Container tags are connected to the network and monitored by the store's electronic fence to prevent the loss or damage of goods and container tags;

[0038] S23. Product prices and related data information may be displayed on the container label display screen, the store reader display screen, or the customer's NFC-enabled mobile phone, and can be updated and adjusted in real time, facilitating integrated online and offline operations and precise promotion of one item, one price.

[0039] S24. After paying for the goods, the customer can open the container label and take the goods.

[0040] S25. Opening or damaging the container label without paying for the goods triggers a system alarm and / or log.

[0041] Furthermore, a retail method utilizing RFID tag inverted labeling and container tag structure is characterized by: real-time sharing and integrated operation of online and offline retail data. Online customer purchases of a particular item are displayed in real-time on the item's container tag display screen, the store's reader display screen, or the customer's NFC-enabled mobile phone, avoiding disputes and ambiguities between online and offline customers; real-time changes in the offline store's sales status are also reflected online; and the operator can monitor the operational status of each item in real time.

[0042] A logistics method utilizing inverted RFID tag identification and container tag structure, characterized by the following steps:

[0043] S31. The shipper shall place the entrusted items into the container label using an inverted internal labeling method;

[0044] S32. The shipper uses the NFC function of their mobile phone or the logistics company's reader to encrypt and lock the container label. The unlocking password is set and controlled by the shipper.

[0045] S33. When the item arrives at the recipient's location, the sender informs the recipient of the unlocking code.

[0046] S34. The recipient uses their mobile phone's NFC function or the delivery person's reader to open the container tag and take the item.

[0047] S35. Each time the container tag is switched on and / or a vibration intensity threshold or a logistics relationship indicator threshold agreed upon by both parties in the logistics contract triggers the tag's record and / or blockchain record, the logistics trajectory can be traced back, responsibilities can be clarified, and the safety of goods can be ensured.

[0048] The difference between this invention's RFID container tag and the container RFID tag system is as follows: In this invention, the container and the RFID tag are integrated; the container is part of the tag, and the tag is the container. The container tag has an RFID serial number, i.e., a label number. The container tag identifies the IoT object inside the tag container, not the tag container itself. This tag identification method is neither externally pasted, attached, or worn on the object, nor is it embedded inside the object; it is an innovative identification method: inverted embedded identification, where the object is wrapped in the tag. Container tags are different. According to the ISO / PAS18186 standard for RFID cargo tagging systems published by the International Organization for Standardization (ISO), the coding information is divided into two parts and five areas. The first part is divided into four areas storing four types of information: 1. Fixed information (Area A), including serial number, container number, container holder, container type, and dimensions. Clearly, the container tag and the container are related as a tag and an object; the container tag identifies the container, and the container RFID tag is a typical example of an embedded identification method.

[0049] The difference between the RFID container tag of this invention and the smart suitcase is as follows: As mentioned above, the container and the RFID tag of this invention are integrated; the container is part of the tag, and the object identified by the container tag is the IoT object inside the container, not the tag container itself. The smart suitcase is a typical form of built-in embedded identification; the object identified by its RFID tag is the suitcase itself. Therefore, the smart suitcase is still a suitcase, but it is a smarter and more intelligent suitcase with an embedded RFID tag.

[0050] The beneficial effects of this invention are as follows: This invention innovatively proposes a third identification method for RFID tags, distinct from the existing methods of external adhesion, hanging, wearing, and internal embedding for identifying IoT objects: inverted embedded identification. This method places the object within the tag body, enclosed by the tag, and controlled by the tag. While seemingly simple, this method yields surprisingly good results. It overcomes the problems inherent in the two common identification methods of external adhesion, hanging, wearing, and internal embedding, solving the identification problems of many items that were previously unsuitable or inconvenient to use embedded identification, as well as the issues of tag peeling or damage caused by external adhesion, hanging, and wearing methods. Furthermore, it is convenient and flexible, not only without damaging the object but also providing excellent protection. Simultaneously, the tags are reusable, saving resources and reducing costs, which is conducive to the widespread application of RFID and IoT technologies. Moreover, the increased physical space of the tag allows for the integration and loading of more sensors and / or communication modules, providing space and possibilities for tag functional expansion and thus expanding the application scope of RFID tags. The application of this invention will play a positive role in improving industry management and service levels, reducing operating costs, saving social resources, increasing operational efficiency, and innovating business operation models in warehousing, logistics, retail, and other business formats by utilizing modern Internet of Things technology, thereby promoting social and economic development.

[0057] The following embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented and applied in different ways, and various modifications or changes can be made without departing from the spirit of the present invention.

[0058] Example B1 provides an application example of container labels in the retail industry. Radio frequency identification (RFID) tags have been used in the commercial retail sector for decades, but their application remains limited, confined to unmanned supermarket systems for product identification. In supermarkets with staff, barcodes or QR codes are more commonly used for inventory management and sales settlement. Only a few merchants use magnetic nail tags with RFID for theft prevention, resulting in a small application scope and limited technological value. In practical applications, unmanned supermarket systems using RFID tags for product identification, whether externally pasted, attached, or embedded, inevitably lead to situations where large numbers of tags are peeled off or damaged, or large quantities of goods and packaging are damaged, causing significant losses to businesses due to the lack of staff. The RFID embedded labeling method of this invention can effectively change this situation in both unmanned and staffed supermarkets. Specifically, as follows: Figure 1As shown, retail businesses lock their goods in RFID-enabled inverted identification containers by quantity or number of items. The offline sales area is covered by radio frequency (RF) signals, and all information on the identified goods and store dynamics can be displayed in real-time on the enterprise's IoT management system. Product prices and related information are actively and / or passively displayed on the container label display screen 10 and / or the store reader display screen, and also displayed on the customer's mobile phone via NFC. This allows for the integration of appropriate payment methods and security facilities for different operating models, whether unmanned or staffed. When the goods are locked into the container label, real-time image status information and related product information are collected. Information is stored in tags and / or IoT systems, ensuring that online product information is specific to the identified product and not related to other products, making the product information nearly identical for online and offline customers. When offline customers select products in the store, in addition to clearly seeing the actual product inside the transparent container label, they can also view more information about the specific product through the container label display screen 10, the store reader display screen, or the customer's mobile phone NFC function, achieving true integration and unified operation of online and offline retail. When an online customer places an order for a identified product through a network terminal, the product is not immediately taken from the store shelf. The sales system will immediately remove the item from the shelves or mark it as sold. Other customers at the offline sales location can also clearly see that the item has been sold via the item's container label display screen 10, reader display screen, or NFC-enabled mobile phone, avoiding disputes and ambiguities between online and offline customers. If a customer opens or damages an item's container label without paying for it, the system will immediately alarm and / or record the incident to prevent damage and theft. When a customer enters the checkout area with selected items, the checkout system will automatically obtain the information about the items to be checked out through the IoT system and quickly notify the customer via voice and / or other means. Alternatively, the screen may display the amount due for payment. Once the checkout system confirms receipt of payment, it will send a command to the IoT system to unbind and / or unlock the RFID tag of the purchased item. The container tag locking mechanism 8 of the purchased item will then automatically open, or it can be opened with an authorized key. The customer can leave the container tag and take the purchased item. When online customers pick up their purchased items at the physical store themselves or through a third-party delivery service, they can use a mobile app or the interactive shopping screen on the shopping basket or cart in the store to locate the purchased item. By confirming the purchase item retrieval password, they can open the container tag locking mechanism 8, leave the container tag, and take the purchased item.

[0059] Example B2 provides an application example of container labeling in the retail industry. Changing and adjusting price tags at retail outlets is a frequent and tedious task for physical stores, and it's prone to errors. Errors can damage a business's reputation and finances. Current electronic price tag systems greatly improve this situation, making this task convenient, fast, and accurate. However, electronic price tag systems can only price by category, not by individual item. Retail goods vary greatly, especially fresh produce, which is difficult to standardize. Not only do similar products differ significantly, but the quality of fresh produce also changes over time, making it impossible to price items individually or at specific times, hindering precise pricing and promotions. This invention addresses this issue. Figure 1 The RFID-based inverted tagging method shown can more accurately identify the price of individual products in a store than existing electronic price tag systems. It can automatically or manually adjust the selling price based on the differences between a specific product and other similar products, the temperature and humidity conditions of the selling environment, or the duration of the sale and display. It can achieve one price per item and one price per moment, and directly display the price and discount information on the product's box or bag tag display screen 10. It can also obtain or push real-time prices or discount information of specific products through the store reader display screen, the customer's mobile phone NFC function, or online client, so as to realize differentiated and accurate pricing and promotion of products in the store, especially fresh agricultural and sideline products in large chain supermarkets.

[0060] Example B3 provides an application example of container labeling in the pharmaceutical retail industry. Pharmaceutical retail stores differ significantly from other retail stores. In other stores, customers can easily identify product types and locations based on their appearance, finding the items they need. However, pharmaceutical retail stores, within a limited space, may display numerous medicine boxes or bottles of similar sizes and shapes, all printed with dense, colorful text. Without the assistance of pharmacy staff, finding the correct medication by reading the text is like searching for a needle in a haystack. The consequences of buying the wrong medication and having it administered to a patient are unimaginable. Therefore, pharmaceutical retail stores employ many staff to provide guidance and consultation, greatly facilitating customers. However, this undoubtedly increases labor costs. Furthermore, due to various constraints, the professional competence of staff varies, making it difficult to guarantee service quality. Therefore, [the following is a more detailed explanation of the pharmaceutical retail store's approach:] Pharmaceutical retail stores employ numerous staff to provide guidance and consultation, greatly facilitating customers. However, this also increases labor costs. Additionally, due to various factors, the professional competence of staff varies, making it difficult to guarantee service quality. Figure 1The invention illustrates an inverted RFID tagging method for labeling medicine boxes and bottles, utilizing IoT technology for retail drug management. This enables the location and navigation of all RFID-tagged medicines within the store, as well as online medication consultation services. When customers enter the store to purchase medicine, they can use the interactive screen on the shopping basket or cart to input the desired medication name and brand via voice, text, or by scanning the prescription with the screen's camera. The interactive screen will then guide the customer to the desired medication and answer their questions online. Customers can also perform these operations via a mobile app. This method of operating retail medicine effectively reduces labor costs while ensuring service quality.

[0061] Example B4 provides an application example of container labeling in the fresh agricultural and sideline product acquisition, processing, and sales industry. Fresh agricultural and sideline products, compared to other commodities, are characterized by non-standardization, perishability, susceptibility to damage, difficulty in storage, rapid turnover, and wide consumer reach. Because these products are difficult to standardize, customers typically need to go through several comparisons and selections before deciding to purchase each item. This comparison and selection process involves handling and bumping the fresh agricultural and sideline products, leading to damage, contamination, and accelerated spoilage. This results in high losses and difficulty in profitability for modern retail terminals operating in large-scale or chain supermarket models. While some retail methods package fresh agricultural and sideline products in pre-packaged quantities or units to avoid and reduce damage caused by customer selection, this increases disposable packaging material and labor costs, as well as resource and environmental issues, making them less competitive. Therefore, even in today's information age, traditional, extensive, decentralized, and small-scale retail methods for fresh agricultural and sideline products remain prevalent worldwide. Given the homogenization of production and storage technologies for fresh agricultural products, standardizing and digitizing these products, combined with information technology, the Internet of Things, and large-scale operations, is the most effective measure to surpass and replace traditional retail methods for fresh agricultural products. Figure 1The present invention, using an inverted RFID tagging method, centrally sorts, cleans, and processes large-scale centralized acquisitions of fresh agricultural products according to end-retail consumer demand. These products are then packaged into RFID inverted tagging containers according to retail market specifications or quantities. The packaging process stores images of the fresh agricultural products at the time of packaging, along with relevant product information, within the RFID tag and / or IoT system. This process of RFID inverted tagging of acquired and distributed fresh agricultural products constitutes a standardization, digitization, and information-based processing method. Fresh agricultural products with inverted RFID tags not only possess the cost advantages of centralized procurement and processing but also have standardized box or bag specifications and packaging, standardized digital images and data, and interactive functions with information systems. This creates conditions for the integrated operation of online e-commerce and offline physical store sales of fresh agricultural products. Under the protection of the container tag, perishable, easily damaged, and difficult-to-store fresh agricultural products are easier to store, handle, transport, and stack in stores, and withstand customer handling, effectively reducing losses caused by bumps, crushing, and spoilage. By integrating IoT information technology, fresh agricultural products with built-in RFID tags are suitable for large-scale, information-based, automated, and chain-store distribution and operation. This supports online and offline data sharing and integrated operation of fresh agricultural product retail transactions. It supports both wholesale and retail operation models for fresh agricultural products, allowing them to be supplied to large retail malls and chain supermarkets, as well as distributed to self-operated or franchised convenience stores. It supports both in-store and home delivery, ensuring comprehensive quality control. Furthermore, it supports unmanned or minimally staffed operation of offline physical retail stores for fresh agricultural products, reducing operating costs, improving operational efficiency, and promoting the transformation of fresh agricultural product trade and retail business models.

[0062] Example B5 provides an application example of inverted labeling on containers in the logistics industry. In the logistics industry, situations often arise where a shipper entrusts a logistics company to transport goods, but upon arrival at the destination, the recipient discovers that the received goods are different from what the shipper described, or have been switched or are damaged. Because the logistics process involves many personnel and stages, it is difficult to determine responsibility in such disputes. Using… Figure 1The RFID container tag with inverted internal identification method shown in this invention can avoid similar problems. Specifically, the shipper places the entrusted item into the container tag using this method. The shipper uses their own mobile phone's NFC function or the logistics company's reader to encrypt and lock the container tag. The unlocking password is set and controlled by the shipper. When the item arrives at the recipient's location, the shipper sends the unlocking password to the recipient, who then uses their mobile phone's NFC function or the delivery company's reader to open the container tag and retrieve the item. If any abnormality occurs with the item, the logistics trajectory can be traced back based on the tag's opening and closing times and / or vibration intensity thresholds, or logistics relationship indicator thresholds agreed upon by both parties in the logistics contract, such as the temperature of cold chain logistics, the entry and exit times of aquatic products, etc., triggering the tag's records and / or blockchain records. The logistics company's responsibility is to ensure the container tag is intact, safe, and delivered on time.
