[0002] With the development of technology, electronic record management systems and electronic photo albums have been around for many years. However, in many key areas, paper records remain the most common and indispensable. Managing paper records is complex; searching, retrieving, and managing them are all inconvenient, and manual processes are prone to errors. Furthermore, once paper records are contaminated, they are difficult to recover and hard to match with the original information. Utility Model Content

[0003] In view of this, embodiments of this application provide an NFC-based archival information carrier and archival management system to solve the aforementioned problems existing in the prior art.

[0004] According to a first aspect of the embodiments of this application, an NFC-based archival information carrier is provided, comprising:

[0005] The archive information layer is located on the side facing the user.

[0006] An NFC layer is stacked below the file information layer; the NFC layer includes an NFC tag, an anti-metal layer, and a signal shielding layer stacked from top to bottom; wherein the signal shielding layer is constructed to be made of a metal material, and the anti-metal layer is constructed to at least completely cover the bottom surface of the NFC tag;

[0007] A fill layer is at least partially disposed between the file information layer and the NFC layer; at least the NFC tag is configured to be embedded within the fill layer.

[0008] In one embodiment of this application, the filler layer is made of PVC material.

[0009] In one embodiment of this application, the filler layer is made of a soft PVC material and is configured to deform under external force so as to at least embed the NFC tag within the filler layer;

[0010] Alternatively, the filling layer may be made of rigid PVC material, and the bottom surface of the filling layer may have a receiving cavity configured to at least accommodate the NFC tag.

[0011] In one embodiment of this application, the material of the anti-metal layer is selected from: ferrite materials, microwave absorbing materials, and polymer-based composite materials.

[0012] In one embodiment of this application, the archive information layer is made of a non-metallic material.

[0013] In one embodiment of this application, the archival information carrier is a photograph, the archival information layer is a photograph printing layer, and a photograph backing layer is also stacked below the signal shielding layer.

[0014] In one embodiment of this application, the archive information layer includes a metal overlay area configured not to completely overlap with the NFC tag.

[0015] In one embodiment of this application, the metal-covered area is configured not to overlap with the NFC tag.

[0016] In one embodiment of this application, the signal shielding layer, the anti-metal layer, and the file information layer have the same area, and the NFC tag is configured to be embedded separately within the filling layer;

[0017] Alternatively, the signal shielding layer, the anti-metal layer, and the NFC tag have the same area, and the NFC layer is configured to be embedded within the filling layer.

[0018] According to a second aspect of the embodiments of this application, an NFC-based file management system is provided, comprising:

[0019] The archival information carrier according to the first aspect of the embodiments of this application;

[0020] An archive information reading device is used to read archive information from the NFC tag of the archive information carrier.

[0021] In one embodiment of this application, a data management server is further included, which is configured to communicate with the file information reading device to transmit file information to the file information reading device.

[0022] This application provides an NFC-based archival information carrier, which can be a physical object capable of carrying archival information, such as a photograph, paper document, archival packaging, or archival card. The NFC tag in the NFC layer stores archival information, which may include: archival image information, archival text information, archival location information, and archival URL information. Therefore, even if the archival information layer is contaminated, users can retrieve the archival information by reading the NFC tag. Thus, the archival information carrier provided by this application solves the problems of being unable to perform physical comparison and matching after the archival information layer is contaminated, as well as the problems of aging and fading text information that is difficult to read, avoiding the errors that are prone to occur when manually processing archival information. Users can read the archival information in the NFC tag without opening the archive, thereby improving the efficiency of archival management. Users can confirm the storage location of the archive based on the archival location information, thus easily and quickly finding the correct storage location of the archive after it has been borrowed and returned.

[0023] Furthermore, the NFC layer also includes an anti-metal layer and a signal shielding layer. When multiple archival information carriers are stacked, the signal shielding layer, made of metal, can block the NFC signals below. The anti-metal layer above the signal shielding layer ensures that the signals emitted by the NFC tags in this NFC layer are not blocked. Thus, this application guarantees that during reading, the reading device can only recognize the topmost NFC signal and will not recognize NFC signals belonging to other archival information carriers below it, thereby avoiding signal crosstalk and improving the accuracy of archival information reading.

[0036] Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] First, the terms and concepts involved in one or more embodiments of this application will be explained.

[0039] NFC, or Near Field Communication, is a short-range wireless communication technology that allows electronic devices to quickly exchange data when they are close to each other (usually within 4 centimeters). NFC was developed based on contactless radio frequency identification (RFID) technology and combined with wireless interconnection technology, providing a very secure and fast communication method for various electronic products in daily life.

[0040] NFC Tags: An NFC tag is a near-field communication device that does not rely on its own power source. It can exchange data with an NFC reader via short-range wireless signals. When an NFC reader approaches an NFC tag, the electromagnetic field emitted by the reader powers the tag, activating its built-in circuitry. The NFC tag then transmits its stored data back to the reader via modulation, thus completing the data exchange.

[0041] NDEF, or NFC Data Exchange Format, is a standardized data format used to exchange information between any compatible NFC device and another NFC device or tag. The data format consists of NDEF messages and NDEF records. This standard is maintained by the NFC Forum, which defines several commonly used formats for data exchange in different scenarios.

[0042] This application provides an NFC-based archival information carrier and archival management system, which will be described in detail in the following embodiments.

[0043] refer to Figures 1 to 4 This disclosure provides an NFC-based archival information carrier 100. Specifically, the carrier can be a photograph, paper document, archival packaging, archival card, or other physical object capable of carrying archival information. The archival information carrier 100 includes an archival information layer 1, an NFC layer 2, and a filling layer 3. The archival information layer 1 is disposed on the side facing the user, and its surface can be provided with archival information for direct identification and reading by the user. For example, in a specific embodiment of this application, the archival information carrier 100 can be a photograph, in which case the archival information layer 1 is a photograph printing layer. When the archival information carrier 100 can be a photograph, such as... Figure 3As shown, a photo backing layer 4 is also stacked below the signal shielding layer 23. Release paper can be adhered to the bottom surface of the photo backing layer 4 so that users can attach photos to file folders or paper files.

[0044] Traditional paper photographs are easily contaminated, making the information difficult to read. To address this issue, this application incorporates an NFC layer 2 within the archival information carrier 100. The NFC layer 2 is stacked below the archival information layer 1, ensuring that the user does not directly see or touch it. The NFC layer 2 includes, from top to bottom, an NFC tag 21, an anti-metallic layer 22, and a signal shielding layer 23, stacked sequentially. The NFC tag 21 stores archival information, which may include: archival image information, archival text information, archival location information, archival URL information, etc. Therefore, even if the archival information layer 1 is contaminated, the user can retrieve the archival information by reading the NFC tag 21.

[0045] Specifically, when a user uses the file information reading device 200 to read the NFC tag 21, the user can display images such as photos based on the file image information stored in the tag, view the text in the file based on the file text information stored in the tag, find out the storage location of the file based on the file location information stored in the tag, and open the corresponding file display interface based on the file URL information stored in the tag.

[0046] In one specific embodiment of this application, the compressed image information can be stored in the Icon Record area of ​​the Smart Poster type according to the standard NFC Data Exchange Format (NDEF), thus ensuring that the physical image of the document can be obtained even without a network connection. Furthermore, the image download address can be stored in the URL Record area of ​​the Smart Poster type, and the action to be performed when reading the tag (image download action) can be stored in the Action Record area of ​​the Smart Poster type. The text information of the document can be stored in the Text type according to the standard NFC Data Exchange Format (NDEF), thus ensuring that the text information of the document can be obtained even without a network connection.

[0047] The archival information carrier 100 provided in this application solves the problem of entity comparison and matching being impossible after the archival information layer 1 becomes contaminated, and also solves the problem of aging and fading text information in the archival information layer 1, making it difficult to identify, thus avoiding the problem of errors easily caused by manual processing of archival information. Users can read the archival information in the NFC tag 21 without opening the file bag, thereby improving the efficiency of archival archiving and management. Based on the archival location information in the archival information, users can confirm the storage location of the file, thus making it convenient and quick to find the correct storage location of the file after it is borrowed and returned.

[0048] refer to Figure 5 In one specific embodiment of this application, the NFC tag 21 includes a chip 211 and an antenna 212. The chip 211 may be located at the center, and the antenna 212 forms a coil circuit around the chip 211. The chip 211 is used to store various types of file information corresponding to the file information carrier 100, and the antenna 212 surrounding the chip 211 is used to generate induced current. When a user brings the file information reading device 200 close to the file information carrier 100, the magnetic field generated by the file information reading device 200 can couple to the surrounding antenna 212, thereby generating an induced current, which can activate the chip 211 and realize the transmission of signals and data.

[0049] As previously described, an anti-metal layer 22 and a signal shielding layer 23 are sequentially disposed below the NFC tag 21. The signal shielding layer 23 is constructed of a metallic material, and the anti-metal layer 22 is constructed to at least completely cover the bottom surface of the NFC tag 21. The signal shielding layer 23 can be made of materials that isolate signals, including but not limited to metal powder, metal sheets, and metal mesh. The anti-metal layer 22 is made of a special anti-magnetic and wave-absorbing material, thereby solving the problem that the NFC tag 21 cannot be directly attached to a metal surface. In one specific embodiment of this application, the material of the anti-metal layer 22 is selected from ferrite materials, wave-absorbing materials, and polymer-based composite materials. The signal shielding layer 23 can be adhesively bonded below the anti-metal layer 22. In particular, when the signal shielding layer 23 is made of metal powder, the metal powder can be mixed with an adhesive, and the mixture can be directly coated on the bottom surface of the anti-metal layer 22 to form the signal shielding layer 23.

[0050] When multiple archival information carriers 100 are stacked, the signal shielding layer 23 made of metal can shield the NFC signals below it. An anti-metal layer 22 disposed above the signal shielding layer 23 ensures that the signals emitted by the NFC tag 21 in the NFC layer 2 are not blocked. Thus, this application ensures that during reading, the archival information reading device 200 can only recognize the topmost NFC signal and will not recognize NFC signals belonging to other archival information carriers 100 below it, thereby avoiding signal crosstalk and improving the accuracy of archival information reading.

[0051] Furthermore, the archival information carrier 100 also includes a filling layer 3, which is at least partially disposed between the archival information layer 1 and the NFC layer 2, such as... Figure 1 As shown, at least the NFC tag 21 is constructed to be embedded within the filling layer 3. The area of ​​the NFC tag 21 is typically smaller than the document information layer 1, and the loop antenna of the NFC tag 21 results in an uneven surface. If the document information layer 1 is directly attached to the NFC tag 21, the surface of the document information carrier 100 will be uneven, leading to a poor user experience. This application fills the gap between the document information layer 1 and the NFC layer 2 by setting the filling layer 3, thereby improving the overall integrity of the document information carrier 100.

[0052] In one specific embodiment of this application, the filling layer 3 is made of PVC material. PVC material has properties such as waterproofing, fireproofing, and mildew resistance. Therefore, using PVC material to make the filling layer 3 can prevent the archival information carrier 100 from being burned or eroded by water. The filling layer 3 can at least protect the NFC tag 21 embedded therein, thereby improving the risk resistance of the archival information carrier 100 and the stability of the NFC tag 21, thus better protecting the archival information.

[0053] The hardness of PVC material can be controlled by adjusting the content of plasticizer; the lower the plasticizer content, the higher the hardness of the PVC material. In one embodiment of this application, the filler layer 3 is made of soft PVC material, and the filler layer 3 has a certain degree of flexibility. The filler layer 3 is configured to deform under external force so as to at least embed the NFC tag 21 into the filler layer 3. Figure 1 As shown, when producing the document information carrier 100, the NFC layer 2 can be formed first, and the filling layer 3 can be attached below the document information layer 1. Then, the filling layer 3 is pressed onto the top of the NFC layer 2. The NFC tag 21 protruding from the upper surface of the NFC layer 2 can squeeze the flexible filling layer 3. After being pressed flat, the NFC tag 21 can be embedded into the filling layer 3, so that the filling layer 3 tightly fills the gap between the document information layer 1 and the NFC layer 2.

[0054] In another embodiment of this application, the filler layer 3 is made of rigid PVC material. Since the filler layer 3 cannot easily deform, the aforementioned process for multi-layer lamination cannot be used. In this case, a receiving cavity can be formed on the bottom surface of the filler layer 3, configured to at least accommodate the NFC tag 21. The receiving cavity can be formed by cutting a groove in the bottom surface of the filler layer 3, and the volume of the receiving cavity is at least larger than the volume of the NFC tag 21. The inner wall of the receiving cavity does not need to completely adhere to the NFC layer 2; the filler layer 3 only needs to partially surround the NFC tag 21 within it, thus isolating the NFC tag 21 from the outside environment and providing protection.

[0055] In one embodiment of this application, such as Figure 1 As shown, the signal shielding layer 23, the anti-metal layer 22, and the document information layer 1 have the same area, and the NFC tag 21 is constructed to be embedded separately within the filling layer 3. Specifically, since the areas of the signal shielding layer 23 and the anti-metal layer 22 are the same as those of the document information layer 1, no additional filling layer 3 is needed around them to fill the gaps, and their sides can be directly exposed. In this embodiment, only the NFC tag 21 causes unevenness in the document information carrier 100, so it is only necessary to embed the NFC tag 21 separately within the filling layer 3 to achieve an integrated design of the document information carrier 100.

[0056] In another embodiment of this application, such as Figure 2 As shown, the signal shielding layer 23, the anti-metal layer 22, and the NFC tag 21 have the same area, and the NFC layer 2 is constructed to be embedded within the filling layer 3. Specifically, the three layers in the NFC layer 2 are of the same size, and the area of ​​the NFC layer 2 is smaller than that of the document information layer 1. If the document information layer 1 is directly attached to the NFC layer 2, the document information layer 1 will not be fully supported. In this embodiment, the NFC layer 2 needs to be embedded within the filling layer 3, thereby partially surrounding the NFC layer 2 within the filling layer 3. The filling layer 3 can provide a complete and horizontal fabrication for the document information layer 1, thus achieving an integrated design of the document information carrier 100.

[0057] This application does not limit the actual area of ​​the NFC tag 21, signal shielding layer 23, and anti-metal layer 22, nor the actual structure of the embedded filling layer 3. The two embodiments described above are merely illustrative examples. Specifically, the two embodiments described above can be considered preferred embodiments of this application, where the area of ​​the signal shielding layer 23 and the anti-metal layer 22 is limited to be the same as that of the NFC tag 21 or the same as that of the file information layer 1. This facilitates the cutting of the signal shielding layer 23 and the anti-metal layer 22, reducing the difficulty of processing. In practical applications, the areas of the signal shielding layer 23 and the anti-metal layer 22 may not be equal. For example, the area of ​​the anti-metal layer 22 may be equal to the area of ​​the NFC tag 21, and the area of ​​the signal shielding layer 23 may be equal to the area of ​​the file information layer 1. In this case, the NFC tag 21 and the anti-metal layer 22 are jointly embedded in the filling layer 3.

[0058] In one embodiment of this application, the document information layer 1 is made of a non-metallic material. As mentioned above, the document information carrier 100 can be a paper object such as a photograph, paper document, or document packaging, or it can be a document card made of plastic. The document information layer 1, made of a non-metallic material, will not interfere with the signal of the NFC tag 21, thereby ensuring the stability of the NFC signal. The document information reading device 200 can read the NFC tag 21 underneath the document information layer 1.

[0059] In one embodiment of this application, reference is made to Figure 4 The document information layer 1 includes a metal covering area 11. Specifically, the document information layer 1 may have a structure partially made of metal material. For example, the document information carrier 100 may be a document card, and the top surface of the document card (i.e., the document information layer 1) may have a metal border. This part of the structure is defined as the metal covering area 11. The metal covering area 11 will interfere with the signal of the NFC tag 21, and the signal of the NFC tag 21 cannot pass through the metal covering area 11. In order to ensure that the document information reading device 200 can read the NFC tag 21 below it through the document information layer 1, the metal covering area 11 is constructed to not completely overlap with the NFC tag 21. Preferably, the metal covering area 11 is constructed to not overlap with the NFC tag 21. This ensures that the document information layer 1 directly above the NFC tag 21 is made of non-metallic material, and the signal of the NFC tag 21 can pass through the non-metallic document information layer 1 normally, thereby facilitating the document information reading device 200 to read the document information normally.

[0060] This application also provides an NFC-based file management system, such as... Figure 6As shown, the system includes the aforementioned document information carrier 100 and document information reading device 200, wherein the document information reading device 200 is used to read document information from the NFC tag 21 of the document information carrier 100. The document information reading device 200 can be a dedicated NFC reading device or a mobile phone with a dedicated APP installed.

[0061] When reading, the NFC function of the document information reading device 200 is first activated and security authentication is performed. For example, if the document information reading device 200 is a mobile phone with a dedicated APP installed, security authentication can be performed by logging into the APP account, thereby ensuring that the current user has the right to read document information. It is understood that other NFC reading and writing devices that have not undergone security authentication cannot read and / or write the document data in the document information carrier 100, thereby ensuring the security of document information.

[0062] After security authentication, users can bring the document information reading device 200 close to the document information carrier 100 to read the document information in the NFC tag 21. The reading process specifically includes: reading the document NDEF record, decrypting the NDEF record, identifying the NDEF record type, identifying the signature mark, and verifying the signature of the NDEF record data. The NFC tags 21 in the document information carrier 100 undergo security processing before production. The NDEF record is first processed using a hash algorithm, and the hash result is signed. Then, it is encrypted using a public key and finally written into the NFC tag 21. Verification is required for each read, thereby further enhancing the security and reliability of the document information. This establishes a secure and reliable connection between the NFC tag 21 and the document information reading device 200 during communication, ensuring the authenticity, integrity, and confidentiality of various document information data transmissions, and effectively preventing tampering with the content in the NFC tag 21.

[0063] After the signature authentication is passed, the file information recorded in the NFC tag 21 can be successfully extracted. The information extraction process can specifically include: extracting file text information from Text type records, extracting file location information from Text type records, extracting file image information from Smart Poster type records, and extracting file URL information (i.e., the address of the file display interface) from URL type records. When connected to the Internet, the obtained file URL information can be used to access the file display interface.

[0064] In one embodiment of this application, such as Figure 6As shown, the document management system also includes a data management server 300, which is configured to communicate with the document information reading device 200 to transmit document information. Specifically, the data management server 300 can be connected to the document information reading device 200 via a network. The data management server 300 can be used for network management of the document information in the NFC tag 21 of the document information carrier 100 read by the document information reading device 200. For example, it can be used to build a document database, collect the reading and access records of the document information reading device 200, and display the document information read by the document information reading device 200. For example, the data management server 300 can be a computer, and the document information reading device 200 can be an NFC reader. After the NFC reader obtains the document information in the NFC tag 21 of a certain document information carrier 100, the NFC reader can transmit the document information to the computer, thereby displaying the document information on the computer screen.

[0065] When the network connection is normal, the data management server 300 and the document information reading device 200 are connected via the network. The document information reading device 200 can activate the NFC function and approach the document information carrier 100 while connected to the network, thereby obtaining the document information stored in the NFC tag 21 of a certain document information carrier 100 through NDEF interaction. At this time, the image download address stored in the URL Record area of ​​the Smart Poster type can be used first, and the data management server 300 can perform the image download action to download the document image for later display and comparison. In addition, it can also read the document text information and document location information recorded in the Text type. The above information can be transmitted to the data management server 300 for display.

[0066] When the network connection is abnormal, the data management server 300 cannot establish a connection with the document information reading device 200. The document information reading device 200 activates the NFC function in the offline state and approaches the document information carrier 100, thereby obtaining the document information stored in the NFC tag 21 of a certain document information carrier 100 through NDEF interaction. At this time, the icon data record stored in the Icon Record area of ​​the Smart Poster type can be used first. The document information reading device 200 can decompress the icon data to obtain the document image information for later display and comparison.

[0067] The document management system provided in this application can operate normally both online and offline. Compared with traditional paper document management systems, the NFC-based document management system provided in this application achieves digital management while preserving paper documents, avoiding problems such as the inability to compare and match physical documents after they are contaminated, the easy fading and difficulty in recognizing text and image information due to aging, and the easy occurrence of typos in manual data entry. By using this system, users can obtain the document information in the document information carrier 100 without opening the document bag using the document information reading device 200, thereby significantly improving the efficiency of document management. The document information may include document location information, which allows users to quickly confirm the storage location of the document, thus facilitating the quick and easy retrieval of the correct storage location after the borrowed document is returned.
