[0002] With the rapid development of informatization, IC cards have become an indispensable tool in everyone's life, such as bank cards, social security cards, etc. Traditional IC cards are cumbersome to use, and users need to go to offline outlets to perform related operations. With the development of NFC technology, cards can be read through mobile phones and other devices, but when the information on the IC card needs to be modified, it is still necessary to go to offline outlets to make changes. At present, there is a lack of an IC card reading and writing solution that can take into account both ease of use and convenience in the market. Summary of the invention

[0003] To solve the above problems, the present invention provides an NFC-based IC card reading and writing system and method, which performs reading and writing operations on IC cards through the NFC module, and cooperates with the front and back ends to facilitate user operations, thereby solving the problems of strong reading and writing limitations and poor usability of existing IC cards.

[0008] The back-end module is used to respond to the instructions issued by the front-end module, read the IC card database, and synchronize the IC card information.

[0009] Furthermore, the front-end module is a WeChat applet, which responds to external operations through the WeChat applet interface.

[0010] Furthermore, the operation instructions include query instructions, modification instructions and reset instructions.

[0011] Furthermore, the IC card database is used to store IC card information and user identity data corresponding to each IC card.

[0013] Furthermore, it also includes: encrypting IC card information and user identity data during the communication process to prevent the data from being illegally obtained or tampered with.

[0014] Furthermore, it also includes: the back-end module records each operation of the user on the IC card, generates an operation log, and stores the operation log in the IC card database.

[0017] Figure 2 The figure is a schematic diagram of the overall process of an NFC-based IC card reading and writing method in an embodiment of the present invention. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] See also Figure 1 , an IC card reading and writing system based on NFC, comprising:

[0022] The front-end module is used to respond to external operations, issue operation instructions to the NFC module and the back-end module according to the external operations, receive data returned by the NFC module and the back-end module, and display the returned data;

[0023] The NFC module is used to respond to the operation instructions issued by the front-end module, interact with the IC card through NFC according to the instructions, perform read and write operations on the IC card close to the NFC module, and return the read IC card information to the front-end module;

[0024] The back-end module is used to respond to the instructions issued by the front-end module, read the IC card database, and synchronize the IC card information.

[0025] NFC stands for Near Field Communication. NFC is developed based on contactless radio frequency identification technology combined with wireless interconnection technology. It provides a very safe and fast communication method for various electronic products. The present invention interacts with IC cards based on the built-in NFC function of smart phones, so that data can be read and modified on IC cards in a portable manner.

[0026] In an optional embodiment, the front-end module is a WeChat applet, which responds to external operations through the WeChat applet interface.

[0027] The present invention mainly uses a smart phone in conjunction with a WeChat applet to read and write data on IC cards such as bank cards and social security cards, and uses the WeChat applet as a front-end platform for user operations. Users do not need to download other application software, and can directly use the above functions through WeChat, thereby lowering the user's usage threshold.

[0028] In an optional embodiment, the operation instruction includes a query instruction, a modification instruction and a reset instruction.

[0029] Users can operate through the WeChat mini program and use the NFC function to read information such as social security cards or bank cards, including card numbers, cardholder information, balances and other data.

[0030] When the user needs to modify the PIN code of the IC card, he / she can send a write request through the WeChat applet to write the data into the social security card.

[0031] When a user needs to reset the PIN code of the social security card, he / she can send a write request through the WeChat applet to write the data into the social security card.

[0032] In an optional embodiment, the IC card database is used to store IC card information and user identity data corresponding to each IC card.

[0033] The database stores information such as the IC card number and PIN code. When the user modifies the IC card through NFC, the back-end also synchronizes the database with the cloud to ensure the consistency of user information.

[0034] In an optional embodiment, after the front-end module issues an operation instruction to the NFC module and the back-end module according to the external operation, it also includes: authenticating the user according to the user identity data corresponding to the IC card in the IC card database, and when the user identity data corresponding to the IC card does not match the current operating user identity, denying the user access to the data.

[0035] The IC card database stores the user's identity information, including the user's biometric data, such as face data and fingerprint data. When the user requests access to the IC card information, the mobile device equipped with NFC function authenticates the current user and uses the biometric information for matching verification to ensure the user's information security.

[0036] In an optional embodiment, it also includes: encrypting the IC card information and user identity data during the communication process to prevent the data from being illegally obtained or tampered with.

[0037] When transmitting NFC data, a symmetric encryption algorithm is used to encrypt sensitive data to prevent the data from being illegally intercepted or tampered with, thereby protecting the privacy and security of users.

[0038] In an optional embodiment, it also includes: the back-end module records each operation of the user on the IC card, generates an operation log, and stores the operation log in the IC card database.

[0039] Each time the IC card information is operated, each operation information is recorded and saved, including the time of the read and write operation, the operation content and other information, which is convenient for later operation tracking and statistics, and improves the security and reliability of the system. The present invention combines NFC technology with the WeChat applet platform, and uses the WeChat applet to realize the reading and writing functions of the social security card, which has extremely high practicality and market promotion potential.

[0040] In an optional embodiment, the WeChat payment interface is connected to the IC card recharge interface to simplify the cumbersome recharge process of the traditional IC card, and the security of WeChat payment is used to ensure the safety of users' funds, thereby improving the convenience of IC card use.
