Description

Technical Field

[0001] This utility model relates to the field of smart card technology, and in particular to a multi-layer wood laminate composite contactless smart card. Background Technology

[0002] Existing contactless smart cards are typically made of PVC (Polyvinyl Chloride) synthetic plastic. While PVC is soft, elastic, and fold-resistant, it is not environmentally friendly. Plastic waste is generated when cards expire, are replaced, or are discarded, requiring special treatment and incurring high disposal costs. Furthermore, plastic smart cards are usually a single color with no texture or pattern on their surface. They typically have a laminated film printed with colors, patterns, and text on both sides for decoration and information display. The application of these colors, patterns, and text requires chemical pigments, necessitating protective measures and wastewater treatment in the production workshop, resulting in high costs and environmental impact. Therefore, this technical solution aims to propose a multi-layer wood-laminated composite contactless smart card solution that is both environmentally friendly and easy to manufacture. Utility Model Content

[0003] The technical solution disclosed in this utility model is a multi-layer wood-laminated composite contactless smart card, comprising a first wood layer, a biodegradable plastic sheet layer, an IC chip, a coil, and a second wood layer. The first wood layer has a mounting position for installing the IC chip. The biodegradable plastic sheet layer has a through hole corresponding to the mounting position. The upper surface of the IC chip is exposed through the through hole. The coil is ultrasonically implanted and wound to the upper surface of the biodegradable plastic sheet layer, and the coil is spot-welded to the upper surface of the IC chip. The bottom surface of the biodegradable plastic sheet layer is laminated and bonded to the top surface of the first wood layer, and the top surface of the biodegradable plastic sheet layer is laminated and bonded to the bottom surface of the second wood layer.

[0004] Furthermore, the biodegradable plastic sheet layer is any one of biodegradable PVC sheet, biodegradable PET sheet, biodegradable ABS sheet, and biodegradable PC sheet.

[0005] Furthermore, the mounting position of the first wooden layer is a non-penetrating groove, and the IC chip is embedded in the groove.

[0006] Preferably, a third wood layer is laminated and bonded to the bottom surface of the first wood layer, a fourth wood layer is laminated and bonded to the top surface of the second wood layer, and the mounting position of the first wood layer is a through hole.

[0007] Preferably, the first, second, third, and fourth wood layers are made of any one of the following woods: linden, beech, cherry, sapele, black walnut, bamboo, birch, and elm.

[0008] Preferably, both the first and second wood layers have "#" shaped through-holes. When the first wood layer, the biodegradable plastic sheet layer, the second wood layer, the third wood layer, and the fourth wood layer are laminated and bonded, the "#" shaped through-holes are filled with adhesive. After the adhesive in the "#" shaped through-holes is cured, it forms an internal support skeleton to improve the card's bending resistance.

[0009] The beneficial effects of this utility model are as follows: The multi-layer wood-laminated contactless smart card disclosed in this solution uses upper and lower degradable plastic sheet layers sandwiched together. A coil is set on the degradable plastic sheet layer, and an IC chip mounting position is set on the wood layer. One wood layer is laminated and bonded to each of the upper and lower layers of the degradable plastic sheet layer, or two wood layers are laminated and bonded together. Using wood layers as the main body of the smart card and the degradable plastic sheet layer reduces plastic waste generation, environmental pollution, and waste disposal costs after the card becomes invalid or unusable. The smart card, manufactured through wood-laminated lamination, has the natural wood grain on its surface. Patterns and text can be laser-engraved or printed without further lamination, making the production process more environmentally friendly.

[0010] In addition, depending on the selected wood material, a "#" shaped through-hole can be provided in the outermost layer of the laminated wood layer, namely the first wood layer and the second wood layer described in this solution. Adhesive is filled in the "#" shaped through-hole. After the adhesive cures, it forms an internal support skeleton, which is more conducive to improving the card's bending resistance.
