Description
Technical Field
[0001] The utility model relates to the technical field of electronic cards, in particular to an inlaid wooden smart card. Background Art
[0002] A smart card is a plastic card with a built-in microchip that can store and transmit data for communication. It mainly includes two categories: contact smart cards and non-contact smart cards (including dual-interface chips or non-contact chip cards). Among them, contact smart cards usually use IC card technology and need to physically contact the card reader to exchange data. Non-contact smart cards, also known as touchless smart cards, allow data transmission through radio waves without physically contacting the card reader. Such cards use a 13.56 MHz wireless signal, and the embedded integrated circuit can store and transmit data. Non-contact smart cards include read-only RFID and CSN (Card Serial Number) or UID, which can communicate through radio waves and rewrite the chip information on the smart card. The advantage of this kind of card lies in its convenience of use and is suitable for various application scenarios, such as transportation, access control systems, etc. Existing smart cards mainly use non-renewable petrochemical-based materials such as PVC, PC, and PET as materials for producing the card body. Due to the convenience brought by the use of smart cards to life, the number of smart cards used globally is extremely large. Smart cards will be discarded due to factors such as technological upgrading, expiration of service life, damage, or being replaced. Most people are worried that the card information will be stolen and directly cut them into pieces and discard them, resulting in difficulties in resource recycling and environmental pollution due to non-degradability. Therefore, those skilled in the art have improved smart cards and designed smart cards made of wood materials. However, in existing wooden smart cards, wood veneer and coated glue are used as carriers for coils and chips, resulting in high manufacturing costs and easy breakage of the internal coils when the wooden smart card is bent, leading to card failure. Content of the Utility Model
[0003] In view of this, the utility model provides an inlaid wooden smart card with a more reasonable structural design. By setting a wooden frame layer, the INLAY layer of the smart card is embedded in the wooden frame layer, and wooden outer layers are provided on the upper and lower surfaces of the wooden frame layer, thereby realizing a wooden smart card. The wooden material is degradable, which is beneficial to environmental protection and has better bending resistance. The coils of the INLAY layer are not easily broken, improving the service life of the wooden smart card.
[0004] The technical solution disclosed by the present utility model is an inlaid wooden smart card, which includes a card base and an INLAY layer. The card base includes a wooden frame layer, a first wooden outer layer, and a second wooden outer layer. The wooden frame layer includes at least one layer, and the outer edge dimensions of the wooden frame layer are the same as those of the first wooden outer layer and the second wooden outer layer. A first punching hole position is provided inside the wooden frame layer, and the INLAY layer is inlaid in the first punching hole position. The wooden frame layer is laminated between the first wooden outer layer and the second wooden outer layer, and the first wooden outer layer, the second wooden outer layer are bonded to the wooden frame layer and the INLAY layer.
[0005] Furthermore, the INLAY layer includes a plastic thin sheet, a coil, and a chip. The coil is wound and implanted into the plastic thin sheet through an ultrasonic wire embedder, and the chip is welded to the coil.
[0006] Furthermore, the plastic thin sheet adopts any one of PVC thin sheets, ABS thin sheets, PET thin sheets, PETG thin sheets, and PC thin sheets.
[0007] Furthermore, the coil and the chip are coupled by an inductance coil and an RFID chip, and the formed INLAY layer is a non-contact radio frequency identification INLAY unit.
[0008] Furthermore, the coil and the chip are coupled by an induction coil and a memory chip, and the formed INLAY layer is a contact reading INLAY unit.
[0009] Furthermore, the coil and the chip are coupled by a dual induction coil and a CPU chip, and the formed INLAY layer is a dual-interface smart card INLAY unit.
[0010] Furthermore, a contact point metal sheet is coupled on the upper layer of the chip. A second punching hole position is provided on the first wooden outer layer, and the contact point metal sheet is inlaid and exposed in the second punching hole position.
[0011] Furthermore, the first wooden outer layer, the second wooden outer layer, and the wooden frame layer adopt any one of basswood, beech, cherry, sapelli, black walnut, birch, bamboo, and elm. The first wooden outer layer and the second wooden outer layer are made of the same kind of wood, and the wooden frame layer adopts wood harder than the first wooden outer layer and the second wooden outer layer.
[0012] Furthermore, the thickness of the first wooden outer layer and the second wooden outer layer is 0.15 - 0.3mm ± 0.08mm, the thickness of the wooden frame layer is 0.15 - 0.50mm ± 0.05mm. Glue or hot melt adhesive paper is coated on the surface where the first wooden outer layer, the second wooden outer layer are bonded to the INLAY layer, so that the thickness after bonding the first wooden outer layer, the second wooden outer layer to the wooden frame layer is 0.68mm - 1.40mm.
[0013] The inlaid wooden smart card designed by this solution has the following beneficial effects compared with the existing wooden smart cards. It retains the INLAY layer carrier made of traditional plastic material. The card base (the basic material of the smart card) of the wooden smart card is designed with wooden material. An inlaid wooden frame layer for placing the INLAY layer is designed, and the INLAY layer is protected by the wooden frame layer. Then, the first wooden outer layer and the second wooden outer layer are press-bonded on the upper and lower surfaces of the wooden frame layer. The wooden frame layer includes at least one layer. When the first wooden outer layer and the second wooden outer layer meet the thickness standard of the smart card, the wooden frame layer can be adjusted to be set from one layer to three layers as needed. In this way, through the composite bonding of multiple wooden frame layers, the anti-bending performance of the wooden frame layer is better, which is beneficial to protecting the coil of the INLAY layer from being easily broken and improving the service life of the wooden smart card. On the other hand, at the same time, the first wooden outer layer, the second wooden outer layer and the wooden frame layer are made of wooden materials and are easily degradable. Compared with the traditional plastic card base, it is beneficial to reduce plastic pollution. BRIEF DESCRIPTION OF THE DRAWINGS
