Description

[0001] The present utility model relates to the technical field of jewelry, in particular a wearable NFC bracelet.

[0002] NFC chip cards are commonplace in various scenarios, such as bus tickets, access control cards, attendance cards, and memory cards, and are widely used due to their convenience and security. However, the increasing variety of card types leads to problems like forgetting them or their portability. Therefore, there's a tendency to integrate cards into smartphones or other devices. While this offers significant advantages, it also has certain limitations: 1. Opening these cards requires relatively complex operation, which is actually impractical for frequently used cards like bus tickets compared to physical cards; 2. Devices like smartphones cannot be used without power, creating problems such as when a phone battery dies and you need to get off the subway; 3. They are dependent on a network. Some cards are also available on the market in the form of key fobs or cartoon stickers.These forms can solve some problems such as forgetting or power outages, but due to a lack of aesthetics, lack of protection against loss, and other problems, they are not widely used.

[0003] In summary, the physical card, using the bus ticket as an example, has the following disadvantages: 1. no protection against loss; 2. easy to forget to take with you; 3. Space constraints in clothing, especially inconvenience for women without pockets; 4. It also takes time to search for them among the items brought along when needed.

[0004] Mobile bus tickets have the following disadvantages: 1. Several steps are required to pay with the card; 2. No discount on the trip; 3. Dependence on and concern about electricity consumption; 4. Dependence on and concern for the network.

[0005] Compared to both physical cards and mobile network SIM cards, the bracelet is a piece of jewelry worn on the wrist by many women daily. Men's models with matching designs are also available. Due to its portability, aesthetic appeal, and other similar qualities, it almost perfectly eliminates the disadvantages of the aforementioned physical NFC cards and mobile network SIM cards. Thus, the combination of a bracelet and an NFC card is a connection where 1 plus 1 equals far more than 2.

[0006] However, due to the shielding effect of metal on the signal, it is difficult to integrate a secondary function, including communication capabilities, into popular precious metals like gold and platinum, as well as other jewelry. Meanwhile, non-metallic materials, which are signal-friendly, can be difficult to widespread due to their lack of aesthetic appeal. This is why, for example, paying for bus tickets with a mobile phone remains common practice.

[0007] Therefore, a wearable NFC wristband is urgently needed at the moment.

[0008] Against this background, the present invention proposes a wearable NFC wristband to solve the problems existing in the technical background. The specific technical solution is as follows: Wearable NFC bracelet comprising a bracelet body which is ring-shaped as a whole, the inner part of which is a cavity, within the cavity an NFC chip and a communication coil are provided, both ends of the NFC chip are connected to both ends of the communication coil, the bracelet body has a recess at a point near the NFC chip, at which a connection is made by an inside-outside insertion method and a waterproof insulating ring is provided.

[0009] Furthermore, the NFC chip is connected in parallel to a decorative LED indicator light, serving both as decoration and as an indicator.

[0010] Furthermore, the NFC chip can be a bus ticket, an access control card, a campus card, an attendance card, etc., but is not limited to these.

[0011] Furthermore, the bracelet body is made of metal material, for example gold or silver.

[0012] Furthermore, the NFC chip includes a bus ticket, an access control card, and a campus card.

[0013] The aforementioned technical solution has the following advantageous effects: The complete design of this utility model is a ring-shaped bracelet that can simultaneously offer various NFC card functions, such as bus tickets, access control cards, campus cards, etc. Its advantages include: the material can be precious metals like gold, combining aesthetic appeal, lasting value, heirloom quality, and technological properties; its portability perfectly solves the problems of traditional NFC cards, such as the risk of loss, forgetting to carry it, and temporary searching; it eliminates concerns about power consumption and network coverage, as is the case with mobile network cards; and it addresses the issues of numerous operating steps and the lack of fare discounts, as is the case with mobile network cards. Fig. shows a schematic representation of the cross-sectional structure of a wearable NFC wristband of the present utility model; Fig. shows an enlarged diagram of a region A in Fig. ; Fig. shows a schematic representation of the vertical section structure of the present utility model;

[0014] In the illustrations: 1 - bracelet body; 2 - cavity; 3 - communication coil; 4 - waterproof insulation ring; 5 - decorative indicator LED light; 6 - NFC chip.

[0015] The technical solution in the embodiments of this utility model is clearly and completely described below in conjunction with the illustrations in those embodiments. Obviously, the described embodiments are part of the embodiments of this utility model and not the entirety of them. All other embodiments that could have been obtained by a person skilled in the art without inventive effort based on the embodiments specified in this utility model fall within the scope of protection of this utility model.

[0016] As in Fig.The portable NFC wristband shown comprises a wristband body 1, the inner part of which is designed as a cavity 2. An NFC chip and a communication coil 3 are provided within the cavity. Both ends of the NFC chip are connected to both ends of the communication coil 3. An isolation point must be provided if the wristband body 1 is made of metal; an inside-outside insertion method may be used for the isolation point. Both ends of the NFC chip 6 are connected to both ends of the communication coil 3. The wristband body 1 has a recess near the NFC chip 6, at which a connection is made by an inside-outside insertion method, and a waterproof isolation ring 4, which is a sealing ring, is provided.

[0017] In the present embodiment, the NFC chip 6 can be multiple chips with different frequency bands, such as a 13.56 MHz bus ticket or a 125 kHz access control card. The wristband body 1 can be made of metal, and an insulating point must be provided on the metal material. The two ends of the chip are each connected to a communication coil 3 that corresponds to the frequency characteristics of the appropriate chip, such as 13.56 MHz or 125 kHz. Optionally, a decorative indicator LED 5 can be attached to the NFC chip to enhance its decorative appeal and indicator function.

[0018] The bracelet of the present utility model is combined with an NFC chip, thus forming a digital technological piece of jewelry. The present utility model utilizes the law of electromagnetic induction: In a closed conductor, a changing magnetic flux can generate an induced current. Therefore, the metal casing of the bracelet body 1 of the present utility model, through the design of the insulation point, prevents the formation of a closed circuit, thereby avoiding an induced current and thus signal shielding. The internal communication coil 3 acts as the conductor of a closed circuit and enables the communication function through the electromagnetic induced current.

[0019] The present utility model consists of a ring-shaped bracelet. Due to the internal-external interlocking method and the electrical insulation and waterproofing methods, the product's overall shape remains identical to that of common bracelets on the market. This does not impair the wearability of the bracelet body 1. The NFC communication coil 3 is integrated within the bracelet, and both ends of the recess are sealed to be waterproof, thus achieving a watertight seal. The present utility model has a simple structure and is user-friendly. It can be worn as jewelry as well as used for purposes such as bus tickets and access control cards.
