Description

Technical Field

[0001] The utility model relates to the technical field of smart cards, in particular to a wear-resistant and waterproof smart card. Background Art

[0002] Smart card is a general term for plastic cards with microchips embedded in them. Smart cards have been widely used in mobile communications, public transportation, medical insurance and other fields. They are mainly used for fee settlement, data storage and system management.

[0003] Smart cards are often subject to friction during carrying. Due to long-term friction, they are prone to losing magnetism and causing gaps between the structures of smart cards. If the smart card is not waterproof, once water seeps into the chip, the smart card may not be used normally. Therefore, we propose a wear-resistant and waterproof smart card. Utility Model Content

[0009] As a preferred solution, a plurality of arched arc plates are evenly arranged inside the wear-resistant base plate.

[0010] As a preferred solution, the side protection component includes a silicone protective cover detachably arranged on the side of the smart card body, and protective corners are respectively arranged at the four corners of the silicone protective cover.

[0011] As a preferred solution, the height of the protective corner is greater than the thickness of the smart card body.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model improves the waterproofness of the smart card through the structural setting of the chip waterproof component, encapsulates the radio frequency sensing device on the chip substrate through the waterproof cover plate, thereby providing waterproof protection for the radio frequency sensing device, the elastic sealing ring at the bottom of the waterproof cover plate is stably stuck in the ring groove, and then waterproof glue is applied in the ring groove, so that the sealing performance of the waterproof cover plate installed in the ring groove is improved, and a nano-hydrophobic layer is provided on the surface of the waterproof cover plate to repel water on the surface of the waterproof cover plate, thereby improving the waterproofness of the smart card.

[0014] Through the structural setting of the wear-resistant protective layer and the use of the side protection component, the wear resistance of the smart card is improved.
