Intelligent card integrated with electrochromic devices and working method of intelligent card

Abstract

The invention discloses an intelligent card integrated with electrochromic devices and a working method of the intelligent card. The intelligent card integrated with the electrochromic devices comprises a main control chip (101), chip pins (102), an antenna (103) and the electrochromic devices (104). The main control chip (101) and the chip pins (102) are connected to achieve a contact mode operation; the main control chip (101) and the antenna (103) are connected to achieve a non-contact operation; through one or more chip pins (102), the main control chip (101) is connected with one or moreelectrochromic devices (104). The electrochromic devices are integrated with a traditional intelligent card chip, simple reminding messages, such as insufficient funds, are sent to users by changing the color of the intelligent card, and the problem that the information of the intelligent card cannot be checked at any time is solved at a low cost.

Description

Technical field [0001] The invention relates to a color changeable smart card, in particular to a smart card integrated with an electrochromic device and a working method thereof. Background technique [0002] The smart card uses a chip as a secure storage and use medium, and a secure chip with a microprocessor, a secure processor and a memory is encapsulated in the card, so it has high computing power, strong security protection capability, and large storage capacity. It can store information that needs to be protected, such as keys and digital certificates, and run a variety of application software safely. Compared with magnetic stripe cards, ID cards and other technologies, it can safely store more consumption records and user information, greatly improve performance, and provide more value-added services. It is widely used in finance, telecommunications, transportation, security management and identity recognition. And other fields. However, the smart card was invented arou...

AI Technical Summary

Problems solved by technology

[0006] In order to achieve the above-mentioned main purpose, a smart card integrating an electrochromic device and its working method described in the present invention integrate a small-sized electrochromic device with a simple structure into a traditional smart card chip, and change the color of the smart card to The user sends a simple reminder message (such as insufficient balance, etc.), which solves the problem that the smart card information cannot be checked at any time at low cost
