Description

Technical Field

[0001] This application relates to the field of electronic tag technology, and in particular to an RFID card set. Background Technology

[0002] Radio Frequency Identification (RFID), also known as wireless radio frequency identification, is a communication technology that uses radio signals to identify specific targets and read / write related data without requiring mechanical or optical contact between the identification system and the target. Due to its convenience, RFID tags are widely used in various scenarios such as access control cards, public transport cards, and bank cards.

[0003] In the hotel industry, RFID cards are also commonly used as room keys. To enhance customer experience, many hotels offer commemorative, customized themed room keys for specific events or themes (such as sporting events or co-branded activities). For example, when hosting a basketball-themed event, a hotel might want to provide guests with a basketball-themed card set containing a main room key and supplementary cards (such as a consumption card or access card). However, when guests store both RFID cards in a card holder or wallet, the electromagnetic waves emitted by the card reader activate multiple chips simultaneously, causing signal interference between the chips. This prevents the card reader from accurately identifying and reading the data of any one card, and could even lead to accidental reading or fraudulent use. Guests must remove the target card separately to use it, which significantly impacts the convenience and fun of the themed card set.

[0004] Therefore, how to provide a themed RFID card set that can both avoid signal interference and accidental reading when combined for secure storage, provide a functional mode in which two cards can be used simultaneously in a combined state, and also have an interesting design has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this application is to provide an RFID card stack that solves the technical problem in the prior art where multiple RFID cards either interfere with each other or cannot be used simultaneously when stacked.

[0006] To achieve the above objectives, this application provides an RFID card set, comprising: The basketball card is a first RFID card, comprising a first chip, a first anti-metal layer, and a first metal layer; The rim card, which is a second RFID card, includes a backboard and a net set on one side of the backboard. A first opening space is defined between the backboard and the net. A second opening space for storing the basketball card is provided on the back of the backboard. The backboard includes a second chip, a second anti-metal layer and a second metal layer. The second metal layer has holes. Both the basketball card and the hoop card can be read and written independently when separated; When the basketball card is stored in the first opening space, the first metal layer covers the hole to form a combined metal layer together with the second metal layer; the first anti-metal layer and the second anti-metal layer are located on both sides of the combined metal layer and are adjacent to the first chip and the second chip respectively, so that the first chip and the second chip can independently perform data reading and writing; When the basketball card is stored in the second opening space, the first chip and the second chip are in a position of mutual interference, so that neither of them can respond to the signal from the external card reader.

[0007] As can be seen, the concept of this application is to enable double-sided reading when the two cards are separated by a specific design (small size and openings) of the metal layers on the two cards.

[0008] Furthermore, this application cleverly utilizes two different storage spaces to achieve drastically different functions: Functional Mode (First Opening Space): When the basketball card is inserted into the net (first opening space), the metal layers of the two cards align, with the first metal layer precisely covering the hole in the second metal layer, forming a complete "combined metal layer." In this state, the first and second anti-metal layers are located on either side of the combined metal layer, adjacent to their respective chips. The presence of the anti-metal layer (such as absorbing material) provides a pathway for the chip's magnetic field, overcoming the shielding effect of the combined metal layer. This allows signals emitted by the card reader to still be received and responded to by both the first and second chips, thus achieving the unique function of both cards being usable in the combined state.

[0009] Secure Mode (Second Opening Space): When the basketball card is inserted into the back pocket (second opening space), the chips of the two cards are designed to be in close proximity and unshielded alignment, resulting in strong signal interference between the two chips (or their coils). In this state, the card reader cannot recognize either card, thus achieving a secure storage function to prevent accidental reading and fraudulent use. When needed, simply remove the card.

[0010] This application provides an innovative RFID card deck that combines fun, functionality (two cards can be used simultaneously), and security (two cards can be disabled) through a precise spatial layout of openings, metal layers, anti-metal layers, and chips.

[0011] Optionally, the back of the basket card includes a non-woven fabric isolation layer from the inside out and a fourth surface decorative layer, and the second opening space is disposed between the non-woven fabric isolation layer and the fourth surface decorative layer.

[0012] As can be seen, the structure clearly defines the specific physical construction of the second opening space (safety mode), and utilizes the existing structural layers to form a storage pocket. The design is ingenious and simplifies the manufacturing process.

[0013] Optionally, the basketball card includes a first surface decorative layer and a second surface decorative layer as its outer layer; the rim card includes a third surface decorative layer and a fourth surface decorative layer as its outer layer; a basketball pattern is printed on the first surface decorative layer, and a rim pattern is printed on the third surface decorative layer.

[0014] As can be seen, the decorative layer, through its basketball and hoop pattern design, gives the product a distinct theme and a high degree of visual appeal. It not only beautifies the product's appearance but also protects the internal structure and increases its durability. Optionally, the decorative layer is made of leather.

[0015] It is evident that using leather as a decorative layer enhances the overall texture, durability, and feel of the product, making it more valuable as a high-end gift or souvenir.

[0016] Optionally, the basketball card is circular, and the basket card is rectangular.

[0017] It is evident that by designing the two cards into specific shapes corresponding to the theme, the visual appeal and thematic expression of the product are greatly enhanced, making it more recognizable and interesting as a themed card set. Attached Figure Description

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0029] This application provides an RFID card stack that, through an ingenious structural design, achieves three different operating modes: separation mode, functional mode, and security mode.

[0030] Separation mode: like Figure 1 As shown, the basketball card 1 is circular, mimicking the shape of a basketball. Its internal structure, from top to bottom, consists of a first surface decoration layer 6, a first chip 3, a first anti-metal layer 4, a first metal layer 5, and a second surface decoration layer 7. The first surface decoration layer 6 serves as the front, printed with a basketball pattern (such as a mesh pattern); the second surface decoration layer 7 serves as the back. The first chip 3 is a standard RFID chip. Crucially, the first metal layer 5 is a thin metal sheet, designed to be smaller than the coil area of ​​the first chip 3, and its position falls entirely within the projection range of the first chip 3 on the coil plane. This design ensures that the first metal layer 5 does not significantly affect the electromagnetic field of the first chip 3, allowing the card reader to read data from both the front and back of the card without difference—making it double-sided.

[0031] like Figure 2As shown, the basketball hoop card 2 is the main card sleeve. Its internal structure also adopts a layered design, consisting of the following layers from front to back: a third surface decorative layer 11, a second metal layer 10, a second anti-metal layer 9, a second chip 8, a non-woven fabric isolation layer 13, and a fourth surface decorative layer 12. The third surface decorative layer 11 serves as the front of the backboard, with a basketball hoop pattern printed on it; the fourth surface decorative layer 12 serves as the back of the backboard. Crucially, the second metal layer 10 has a hole 14 of a specific shape and location. This hole 14 disrupts the shielding integrity of the second metal layer 10, allowing electromagnetic waves to penetrate. Therefore, the card reader can read the data of the second chip 8 from both the front and back of the basketball hoop card 2, meaning the basketball hoop card 2 is also usable on both sides when separated.

[0032] In the separated mode, the first anti-metal layer 4 and the second anti-metal layer 9 (e.g., absorbing material) ensure that each chip can still work stably when it is close to its respective metal layer.

[0033] Functional mode (first opening space): like Figure 3 As shown, the front of the basketball hoop card 2 features a net structure 16, forming a functional first opening space between the net 16 and the backboard 15. This is not only used to simulate the theme of "basketball going into the net," but also serves as a functional structure to allow simultaneous reading of both cards.

[0034] This functional mode is strictly directional. The user needs to insert the basketball card 1 in the correct orientation, that is, the front of the basketball card 1 (the first surface decorative layer 6 with a mesh pattern) faces outward (towards the net 16), while the back of the basketball card 1 (the second surface decorative layer 7) faces the backboard 15 (that is, towards the third surface decorative layer 11).

[0035] When inserted in the correct orientation, as the basketball card 1 is inserted into the first opening space, its first metal layer 5 will precisely align with the second metal layer 10 inside the basketball hoop card 2. Due to this precise positioning, the first metal layer 5 will completely and seamlessly cover the holes 14 on the second metal layer 10.

[0036] At this point, the first metal layer 5 and the second metal layer 10 together form a larger, gapless "composite metal shielding layer." This composite shielding layer physically separates the first chip 3 and the second chip 8.

[0037] The ingenuity of this application lies in the crucial role played by the first anti-metal layer 4 and the second anti-metal layer 9 located on either side of the composite metal layer. They (e.g., as absorbing materials or magnetic field guiding structures) provide an effective pathway for the reader's electromagnetic field, overcoming the shielding effect of the composite metal layer, allowing both the first chip 3 and the second chip 8 to be activated by the reader signal and respond independently. Therefore, in this functional mode, the user can swipe either of the two cards as needed without removing the card.

[0038] If basketball card 1 is inserted with the opposite orientation (i.e., the first surface decorative layer 6 faces the backboard 15), the first metal layer 5 and the second metal layer 10 cannot be aligned. If an effective composite metal layer cannot be formed, neither card can be read normally (the coils of the two chips interfere with each other). If basketball card 1 is inserted with the opposite orientation (i.e., the first surface decorative layer 6 faces the backboard 15), and the first metal layer 5 and the second metal layer 10 are aligned, the magnetic field lines cannot pass through the shielded signal because the first surface decorative layer 6 does not have an anti-metal effect.

[0039] Safe mode (second opening space): like Figure 2 and Figure 4 As shown, on the back of the basketball hoop card 2, between its outermost fourth surface decorative layer 12 and its inner non-woven fabric isolation layer 13, a pocket-shaped second opening space 17 is formed. The fourth surface decorative layer 12 has an opening 18 (shown by the dotted line in the figure) for the basketball card 1 to be inserted.

[0040] This second opening space 17 is only for secure storage. When the basketball card 1 is fully inserted into this second opening space 17, its structure is designed so that the first chip 3 and the second chip 8 (or their coils) are in a close overlapping position, but their metal layers are not aligned to form a shielding layer as in the functional mode.

[0041] In this state, the electromagnetic fields activated by the two cards will generate strong signal interference (i.e., RFID reading conflict), causing the card reader to be unable to accurately identify and read the data of either card.

[0042] This achieves the overall "anti-read" function of the card deck when stored, effectively preventing accidental reading or unauthorized use, and serving as a secure storage solution. When needed, the user removes Basketball Card 1, and the two cards return to their separate state.

[0043] In summary, this solution cleverly utilizes two different combinations of the two cards (first opening and second opening) by designing a small-sized metal layer and a perforated metal layer, combined with an anti-metal layer, to construct a functional mode of "both cards usable" and a security mode of "both cards disabled". It not only solves the signal interference problem when multiple RFID cards are working simultaneously, providing diverse usage scenarios, but also ensures the dual-sided reading functionality of a single card when used separately, combining fun and practicality.

[0044] In this embodiment, each decorative layer is preferably made of leather, and the basket 16 is also cut from leather to enhance the overall texture.

[0045] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
