Description

Technical Field

[0001] This utility model relates to the field of smart card technology, specifically to a smart card that is resistant to breakage and deformation. Background Technology

[0002] A smart card is a portable intelligent carrier with a built-in micro-integrated circuit chip. It is typically made of PVC, PC, or ABS and is categorized by data interaction method into contact, contactless, and dual-interface types, each conforming to international standards such as ISO7816 and ISO14443. At its core, the chip stores user identity information, keys, and transaction data. It relies on encryption algorithms such as DES and RSA, along with a key management system, to build a security barrier, effectively preventing forgery, tampering, and information leakage. It combines information storage, encrypted computation, and two-way data interaction functions, and is widely used in finance, public services, enterprise management, and healthcare. Compared to traditional magnetic stripe cards, it offers higher security, larger storage capacity, and multi-purpose scalability, making it a key tool for achieving identity recognition, electronic payment, and refined data management in the digital age.

[0003] To this end, China Patent Network published a smart card with application number 202221595155.0. By using a glass fiber substrate and etching circuits on the substrate, the stability of the etched circuits and their bonding with the substrate can be well guaranteed, and the difficulty of the processing technology can be reduced. This effectively solves the problems of easy wear, yellowing due to aging, deformation and delamination of existing smart cards based on thermoplastic plastics.

[0004] Although current smart cards on the market meet users' needs to a certain extent, they still have certain shortcomings in use. Specifically, existing smart cards are prone to a series of problems due to physical external forces during daily use: sitting pressure when placed in a pocket, squeezing from hard objects in a bag, accidental bending or dropping can easily deform the soft card substrate, leading to the breakage of the internal precision integrated circuit chip, pin detachment, or breakage of conductive lines. This can result in intermittent malfunctions such as poor contact and unstable signals, or even complete card failure. Based on this, this utility model designs a smart card that is resistant to breakage and deformation to solve the above problems. Utility Model Content

Detailed Implementation

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Example: Figure 1-4 As shown, this utility model provides a technical solution: a smart card that is resistant to breakage and deformation, including a card body 1. A left protective film 2 is fixedly adhered to one side of the card body 1, and a right protective film 10 is fixedly adhered to the other side of the card body 1. The left protective film 2 and the right protective film 10 are both located inside the protective sleeve 3, which can protect the card body 1, the left protective film 2 and the right protective film 10. Rounded corners are provided at the four corners of the card body 1, the left protective film 2 and the right protective film 10 to prevent sharp corners from scratching external objects. A protective sleeve 3 is fixedly sleeved on the outside of the card body 1, and anti-slip protrusions 4 are fixedly installed at equal intervals on the outside of the protective sleeve 3.

[0019] An anti-transformation frame 5 is embedded and fixedly installed inside the card body 1. A copper wire 6 is embedded and fixedly installed inside the card body 1 at the position corresponding to the outer side of the anti-transformation frame 5. The two ends of the copper wire 6 are located on both sides of the anti-transformation frame 5.

[0020] Conductive plates 7 are embedded and fixedly installed in the middle of both sides of the anti-transformation frame 5. One side of the conductive plate 7 is in contact with one end of the copper wire 6, which can transmit signals. A chip 8 is snapped into the inside of the anti-transformation frame 5, and the other side of the conductive plate 7 is in contact with the outside of the chip 8, which facilitates signal transmission. Copper plates 9 are fixedly installed in the middle of both sides of the chip 8.

[0021] The chip 8 is fixed inside the anti-transformation frame 5, thus fixing its position. During the chip 8 connection process, the chip 8 is fixedly connected to the copper sheet 9, allowing the copper sheet 9 to move and contact the outer side of the copper sheet 9 with the conductive plate 7 fixedly installed inside the anti-transformation frame 5. Through the conductive plate 7, the signal inside the chip 8 is transmitted to the copper wire 6. During the use of the card body 1, the left protective film 2 and right protective film 10 fixedly adhered to both sides of the card body 1, respectively, protect both sides of the card body 1 and prevent scratches caused by contact between external objects and the surface of the card body 1. At the same time, the protective sleeve 3 fixedly fitted to the outside of the card body 1 protects the edges of the card body 1 and prevents breakage and deformation when the card body 1 is dropped. Finally, the anti-slip protrusions 4 fixedly installed on the outside of the protective sleeve 3 increase the friction between the protective sleeve 3 and the user's hand, preventing the card body 1 from slipping when the user holds it.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
