[0036] To more clearly illustrate this utility model, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to... Figure 1 The diagram shows a reading and writing system 100 for a wireless radio frequency tag 1 according to a first preferred embodiment of the present invention. The wireless radio frequency tag 1 has a unique identifier code (UID) and a tag storage body 1a. The tag storage body 1a has a storage state, which is one of a non-read-only state and a read-only state. The reading and writing system 100 includes a reading and writing device 20, an electronic device 40, a server 60, and a storage platform 80.

[0037] The read / write device 20 includes a read / write module 22, a device storage 24, and a controller 26. The read / write module 22 is used to read data and write data into the tag storage 1a of the radio frequency tag 1. The controller 26 is electrically connected to the read / write module 22 and the device storage 24.

[0038] The electronic device 40 includes a USB (Universal Serial Bus) interface 42 and a processing device 44. The processing device 44 is electrically connected to the USB interface 42 and is electrically connected to the controller 26 through the USB interface 42. The processing device 44, the server 60, and the storage platform 80 are signal-connected to each other through a network 3. In this embodiment, the controller 26 is connected to the USB interface 42 through a signal line. The electronic device 40 may be, for example, a personal computer or a laptop computer, but is not limited thereto.

[0039] The above architecture enables the reading and writing method of the RFID tag 1 in this embodiment. The reading and writing method includes... Figure 2 and Figure 3 The following steps are shown.

[0040] Step S11: The controller 26 of the read / write device 20 is configured to operate in an HID (Human Interface Device) mode, and reads the unique identification code and storage status of the radio frequency tag 1 through the read / write module 22.

[0041] Step S12: Perform a setting step, the setting step including:

[0042] The processing device 44 requests the controller 26 to operate in a CDC (Communications Device Class) mode; the processing device 44 transmits a pre-address URL to the controller 26 via the USB interface 42, and the controller 26 stores the pre-address URL via the device storage 24; in this embodiment, the pre-address URL is used to connect to the storage platform 80.

[0043] After the device storage 24 stores the pre-URL, the controller 26 switches from the CDC mode to the HID mode. In other embodiments, the request from the processing device 44 to the controller 26 to operate in the CDC mode and the switch from the CDC mode to the HID mode can be omitted as needed. That is, in the setting step, the controller 26 operates in the HID mode throughout.

[0044] Step S13: The controller 26 of the read / write device 20 determines whether the storage state is a non-read-only state. If yes, proceed to step S14; if no, the controller 26 transmits the unique identification code to the USB interface 42 based on the storage state being a read-only state, and the processing device 44 receives the unique identification code through the USB interface 42. In this embodiment, it is also possible to directly proceed to step S20 after the processing device 44 receives the unique identification code through the USB interface 42, as needed.

[0045] Step S14: The controller 26 of the read / write device 20 transmits the non-read-only state to the USB interface 42 based on the storage state being non-read-only. The processing device 44 receives the non-read-only state through the USB interface 42 and, in response to the non-read-only state, transmits a request command to the controller 26 through the USB interface 42. The controller 26 operates in the CDC mode according to the request command. In other embodiments, the controller 26 can also automatically switch from the HID mode to the CDC mode as needed based on the storage state being non-read-only.

[0046] Step S15: The controller 26 combines the pre-URL and the unique identifier into a link URL corresponding to the unique identifier. The controller 26 outputs the link URL corresponding to the unique identifier to the read / write module 22, and the read / write module 22 writes the link URL into the tag storage 1a of the RFID tag 1. In this embodiment, the link URL is used to allow electronic devices that can connect to the network 3 to connect to a digital product passport webpage 2 via the network 3. Figure 4 (Refer to), where, for example, when the preceding URL is "https: / / dpp...com / storagespace / " and the unique identifier is "E0022304FAACB564", the link URL is "https: / / dpp...com / storagespace / E0022304FAACB564".

[0047] Step S16: The device storage 24 stores the link URL, and the controller 26 reads the link URL written in the tag storage 1a through the read / write module 22.

[0048] Step S17: The controller 26 determines whether the link URL in the tag storage 1a is the same as the link URL in the device storage 24; if yes, proceed to step S18; if no, the controller 26 writes the link URL stored in the device storage 24 into the tag storage 1a through the read / write module 22, and then executes step S17 again.

[0049] Step S18: The controller 26 converts the storage state of the tag storage body 1a from the non-read-only state to the read-only state through the read-write module 22.

[0050] In the above, step S18 is not limited to following steps S16 and S17, and steps S16 and S17 can be omitted. Step S18 can be executed directly after step S15.

[0051] Step S19: The controller 26 switches from the CDC mode to the HID mode; in this embodiment, the controller 26 can operate in the HID mode as needed, or the controller 26 can notify the processing device 44, and the processing device 44 can then request the controller 26 to operate in the HID mode through the USB interface 42.

[0052] In the above, step S19 is not limited to following step S18, and step S18 can be omitted. Step S19 can be executed directly after step S17. In addition, steps S16, S17 and S18 can be omitted, and step S19 can be executed directly after step S15.

[0053] Step S20: The processing device 44 connects to the server 60, the processing device 44 creates an object form in the server 60, the controller 26 transmits the unique identification code to the USB interface 42, the processing device 44 receives the unique identification code through the USB interface 42 and transmits the unique identification code to the server 60, and the server 60 imports the unique identification code into the object form to form an object serial number 2b.

[0054] In this embodiment, the server 60 transmits the object form to the storage platform 80 to form object information 2a. The digital product passport webpage 2 links to the object information 2a. In addition to the object serial number 2b, the object information 2a may include, for example, object name, object number, batch number, etc., but is not limited thereto. Thus, an electronic device that can be connected to the network 3 can open the link URL through a web browser to connect to the digital product passport webpage 2 in the storage platform 80 to browse the object information 2a in the digital product passport webpage 2.

[0055] like Figure 5 and Figure 6 The image shows a second preferred embodiment of the wireless radio frequency tag 1 reading and writing system 200, which has a structure that is substantially the same as that of the first embodiment, except that the reading and writing device 20 can be detachably connected to the electronic device 40.

[0056] Through the above architecture, such as Figure 7 and Figure 8 As shown, the reading and writing method of the RFID tag 1 in this embodiment can be performed. It has a similar architecture to the first embodiment, except that the reading and writing method omits steps S14 and S19, and includes the following steps.

[0057] Step S11': The controller 26 of the read / write device 20 reads the unique identification code and storage status of the radio frequency tag 1 through the read / write device 20.

[0058] Step S12': Perform a connection step and a setup step.

[0059] The connection step includes the processing device 44 being electrically connected to the controller 26 via the USB interface 42; in this embodiment, the controller 26 is connected to the USB interface 42 via the signal line, and the electronic device 40 may be, for example, a personal computer or a laptop computer, but is not limited thereto.

[0060] The setting steps include the processing device 44 transmitting the pre-URL to the controller 26 via the USB interface 42, and the controller 26 storing the pre-URL in the device storage 24; after the controller 26 stores the pre-URL in the device storage 24, the controller 26 disconnects the electrical connection with the processing device 44; in this embodiment, the setting steps involve the processing device 44 requesting the controller 26 to operate in the CDC mode, but this is not a limitation.

[0061] Step S13': The controller 26 of the read / write device 20 determines whether the storage state is the non-read-only state. If so, proceed to step S15 to write the link URL into the tag storage 1a through the read / write module 22. Thus, the read / write device 20 can operate independently without being connected to the electronic device 40.

[0062] If not, the connection step is executed. The controller 26 transmits the unique identification code to the USB interface 42 based on the storage state being read-only. The processing device 44 receives the unique identification code through the USB interface 42. Then, the controller 26 disconnects the electrical connection with the processing device 44. In this embodiment, step S20' can also be executed directly after the controller 26 disconnects the electrical connection with the processing device 44, as needed.

[0063] Step S20': Execute the connection step. The processing device 44, the server 60, and the storage platform 80 are connected to each other via the network 3. The processing device 44 connects to the server 60. The processing device 44 creates the object form in the server 60. The controller 26 transmits the unique identification code to the USB interface 42. The processing device 44 receives the unique identification code through the USB interface 42 and transmits the unique identification code to the server 60. The server 60 imports the unique identification code into the object form to form the object serial number 2b.

[0064] In another embodiment, based on the storage state being the read-only state, the read / write device 20 can also connect to the electronic device 40 via a wireless connection, such as Bluetooth, and the connection step is omitted in steps S13' and S20'. The controller 26 can also transmit the unique identification code to the processing device 44 to import the unique identification code into the object form.

[0065] like Figure 9 and Figure 10 The present invention illustrates a reading and writing method for a wireless radio frequency tag 1 according to a third preferred embodiment. It has a structure that is substantially the same as that of the first embodiment, except that step S12 is omitted and the following steps are included.

[0066] Step S15': The controller 26 transmits the unique identification code to the USB interface 42. The processing device 44 receives the unique identification code through the USB interface 42. The processing device 44 combines the unique identification code and the prefix URL into the link URL, and outputs the link URL to the controller 26 through the USB interface 42. The controller 26 outputs the link URL corresponding to the unique identification code to the read / write module 22, and writes the link URL into the tag storage 1a of the radio frequency tag 1 through the read / write module 22.

[0067] In summary, by reading the unique identification code of the RFID tag 1 through the read / write module 22, and by writing the link URL into the tag storage 1a of the RFID tag 1 via the read / write module 22 according to the unique identification code, the RFID tag 1 can serve as a medium for obtaining the link URL, allowing access to the digital product passport webpage 2 via the link URL to obtain the object information 2a. Furthermore, the controller 26 can compare the link URL in the tag storage 1a with the link URL in the device storage 24. If they are different, the read / write module 22 writes the link URL into the tag storage 1a to ensure the correctness of the link URL in the tag storage 1a, thereby avoiding management oversights or user inconvenience and improving overall ease of use.

[0068] The above description is only a preferred and feasible embodiment of this utility model. Any equivalent changes made by applying the specification and claims of this utility model should be included within the patent scope of this utility model.
