[0002] More specifically, the present utility model relates to a cufflink that includes a wireless RFID transponder for communicating with a reading device to transmit data. Background Art

[0003] RFID transponders are commonly used for remote storage and retrieval of data. These RFID transponders are embedded in plastic materials to form everyday portable items. However, these portable items have several drawbacks: they can be forgotten or lost, need to be stored, for example, in a clothing pocket or on a key, and the portable item containing the RFID transponder needs to be taken out for use.

[0004] In addition, these plastic products rarely have aesthetic appeal.

[0005] Therefore, there is a need to improve these portable items for non-contact data transmission using RFID transponders. Summary of the Utility Model

[0006] To this end, the present utility model proposes a method for solving the problems of the prior art.

[0007] In this context, the present utility model proposes a cufflink, which includes a buckle, a button rod capable of passing through the opening of a shirt, and a button forming the lower part of the cufflink, characterized in that the buckle includes:

[0039] Figure 2 is Figure 1 an exploded view of the shown cufflink fastener, showing in perspective the various components integrated in the cufflink fastener according to the present utility model;

[0040] Figure 3 is Figure 1 a cross-sectional view of the shown cufflink.

[0041] In all the figures, unless otherwise specified, the same elements have the same reference numerals. Detailed Embodiment

[0042] Figure 1 is a schematic perspective view of an embodiment of a cufflink 100 according to the present utility model.

[0043] The cufflink 100 includes a fastener 10, a button rod 20 for passing through the opening of a shirt, and a button 30 forming the lower part of the cufflink 100.

[0044] When the cufflink 100 is located at the opening of the shirt, the fastener 10 and the button 30 are the visible parts of the cufflink 100, located on both sides of the opening of the shirt sleeve.

[0045] As Figure 2 shown, this figure shows in perspective the various elements integrated into the fastener 10. The fastener 10 includes a metal body 11, which forms a hollow housing for accommodating and integrating an RFID transponder 40. The top of the metal body 11 is closed by a decorative piece 15, thereby sealing the fastener 10, and the RFID transponder 40 is enclosed within the metal body 11.

[0046] For this purpose, the metal body 11 includes a blind slot 12 for receiving and accommodating the RFID transponder 40.

[0047] RFID or radio frequency identification (English) is a method of remotely storing and retrieving data using radio waves. The system is activated by the transmission of electromagnetic energy between an RFID transponder and an RFID reader (transmitter).

[0048] The RFID transponder 40 generally includes a chip (usually a few millimeters in size) and an antenna.

[0049] According to the geometry of the RFID transponder, the RFID transponder 40 defines an upper surface 40.1, a lower surface 40.2, and at least one side surface 40.3.

[0050] The RFID transponder 40 is integrally placed in the metal body 11 of the buckle 10, particularly in the non-through groove 12, so as to be embedded in the metal body 11. Various non-metallic components are installed inside the metal body 11 to surround each surface of the RFID transponder with an electrically insulating material.

[0051] The non-through groove 12 is used to receive and accommodate a support insert 13 made of an electrically insulating non-metallic material (such as a polymer material).

[0052] In the illustrated embodiment, the non-through groove 12 has a circular profile. However, according to requirements, the profile of the non-through groove 12 can also be other shapes, such as rectangular, square, circular, oval, etc.

[0053] The support insert 13 is made of an electrical insulating material and can be cup-shaped, with its hollowed-out part 13.3 separating the bottom 13.2 and the peripheral edge 13.1.

[0054] The support insert 13 is used to receive the RFID transponder 40 and place it in the hollowed-out part 13.3, while electrically insulating it from the metal body 11. Therefore, the RFID transponder 40 is integrated in the hollowed-out part 13.3 of the support insert 13.

[0055] Between the bottom 13.2 of the support insert 13 and the RFID transponder 40, a ferrite element 14 is provided, thereby forming a ferrite isolation layer between the RFID transponder 40 and the support insert 13 made of an insulating material.

[0056] Here, the ferrite element 14 is disc-shaped and can be inserted into the hollowed-out part 13.3 in the support insert 13. However, other shapes can also be adopted.

[0057] The ferrite element 14 can include an adhesive material, which can be provided on one or two surfaces to facilitate fixing the ferrite element 14 in the support insert and / or fixing it on the RFID transponder 40.

[0058] According to another embodiment, the adhesive layer can be provided on the RFID transponder 40, particularly on the lower surface 40.2, to facilitate supporting the ferrite element, or on the bottom of the non-through groove 12 to strengthen the support insert 13.

[0059] Preferably, the ferrite element 14 covers the entire lower surface 40.2 of the RFID transponder 40.

[0060] As Figure 3 shown, one or more sides (depending on the selected geometry) of the RFID transponder 40 are covered by the peripheral edge 13.1 of the support insert 13.

[0061] The ferrite element 14 functions as an electromagnetic wave absorber.

[0062] The upper surface of the RFID transponder 40 is completely covered by a decorative member 15 made of a non-metallic material (such as a polymer material, a thermoplastic or thermosetting material, a mineral material, etc.).

[0063] The decorative member 15 is used to form the upper part of the metal body 11 and covers the non-through slot 12 and various components integrated in the non-through slot 12. The decorative member 15 is on a shoulder 17 provided on the periphery and kept at a certain distance from the non-through slot 12 of the metal body 11;

[0064] Preferably, the decorative member 15 is fixed to the metal body 11 to form a sealing cap and seal the RFID transponder 40, the ferrite element 14 and the support plug 13 inside the metal body 11.

[0065] In summary, the above structure can embed the RFID transponder 40 in the metal body 11 and electrically insulate it from the metal material through a non-metallic insulating element that completely surrounds the RFID transponder 40. Advantageously, a ferrite element 14 is inserted between the lower surface of the RFID transponder 40 and the support plug 13 to improve data exchange and identification and eliminate electromagnetic interference.

[0066] Of course, those skilled in the art can modify the cufflink according to the present utility model to integrate an active transponder and an energy source to replace the passive RFID transponder described in this application.

[0067] The cufflink according to the present utility model can take various forms, not limited to Figures 1 to 3 the specific form described. Therefore, the cufflink according to the present utility model can be of any shape, such as curved, circular, oval, parallelepipedal, etc.

[0068] The cufflink according to the present utility model can be a bullet-shaped cufflink, a whale-tail cufflink, a cufflink stud, a cufflink chain, a spherical cufflink, etc.

[0069] The metal body 11 of the buckle 10 can be made of steel, stainless steel, titanium, platinum, copper, bronze, silver, gold or an alloy of different metals.

[0070] The RFID transponder 40 of the cufflink 100 according to the present utility model can be used with a reading device for various purposes, especially (but not limited to) membership cards, group membership cards, product warranty cards (such as for jewelry or watches), property cards, access control cards or identity authentication cards, etc.

[0071] Generally speaking, in this application, the term "cover" means that two mutually covering surfaces are in contact with each other.
