[0002] IC card stands for Integrated Circuit Card, also known as smart card.

[0054] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0056] In one embodiment, Figure 1As shown, a contactless IC card data processing method is provided. This embodiment uses the method applied to a terminal as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the contactless IC card data processing method includes steps S102 to S106.

[0057] Step S102: Obtain a card reading instruction.

[0058] Among them, the contactless IC card can be an IC membership card used in retail industries such as supermarkets, fruit stores, and clothing stores. The contactless IC card can be an ID card or an M1 card. The source of the card reading instruction can be a server, or other terminals, or other software and hardware modules in the same terminal that executes the contactless IC card data processing method, which are different from the contactless IC card data processing device. Take the case where the contactless IC card is a supermarket membership card and the source of the card reading instruction is the same terminal as an example. The user shows the membership card to the staff, and the staff sends a card reading instruction to the contactless IC card data processing device of the terminal by clicking the card reading option on the terminal software interface or pressing the card reading button on the terminal keyboard.

[0059] Furthermore, the IC card type is an identifier for identifying a specific type of a contactless IC card. The target type refers to an IC card type that matches the current application environment. Among them, the IC card type can be defined according to actual needs. Also, take the case where the contactless IC card is a supermarket membership card as an example. During the operation of the supermarket, membership cards are issued to customers based on specific supermarket management software. When the supermarket management software is updated, there may be multiple types of membership cards issued to customers based on different supermarket management software. At this time, the software version can be used as the IC card type of the contactless IC card, and the software version of the currently applied supermarket management software can be used as the target type of the contactless IC card.

[0060] Specifically, the card reading instruction includes a target type, and the terminal will obtain the target type when obtaining the card reading instruction. Furthermore, the terminal can obtain the card reading instruction in an active manner or in a passive manner.

[0061] Step S104: reading characteristic data of the contactless IC card based on the card reading instruction, and determining the IC card type of the contactless IC card according to the characteristic data.

[0062] The characteristic data of the contactless IC card refers to the user information and type information stored in the contactless IC card. The user information includes but is not limited to the card number, user name, user password, balance, points and level, etc., and the type information includes but is not limited to the IC card model, card issuance date and software version, etc.

[0063] Specifically, the terminal reads the characteristic data of the contactless IC card based on the card reading instruction, and can determine the IC card type of the contactless IC card according to the characteristic data. Furthermore, the specific method for the terminal to determine the IC card type of the contactless IC card according to the characteristic data is not unique. For example, the IC card type of the contactless IC card can be determined based on the characteristic data and the correspondence between the pre-stored characteristic data and the IC card type; the IC card type of the contactless IC card can also be determined based on the storage location, format or protocol type of the characteristic data.

[0064] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties.

[0065] Step S106: determining whether the IC card type is consistent with the target type, and if the IC card type is inconsistent with the target type, performing type switching processing on the contactless IC card.

[0066] Specifically, after the terminal determines the IC card type of the contactless IC card, it compares the IC card type with the target type contained in the card reading instruction to determine whether the two are consistent. If the two are consistent, the contactless IC card matches the current application environment and no type switching process is required; if the two are inconsistent, the contactless IC card does not match the current application environment and needs to be switched before it can be applied to the current system. At this time, the contactless IC card is switched.

[0067] The specific method for the terminal to perform type switching processing on the contactless IC card is not unique. For example, the read characteristic data can be rewritten into the contactless IC card according to the configuration requirements of the current application environment, such as format conversion, protocol conversion or storage location update, while erasing the original characteristic data and updating the type information of the contactless IC card accordingly; or a conversion algorithm can be written into the contactless IC card and the type information of the contactless IC card can be updated accordingly. The conversion algorithm is used to convert the communication protocol and data format when the contactless IC card is applied to the current application environment, so that the contactless IC card matches the requirements of the current application environment.

[0068] The above-mentioned contactless IC card data processing method reads the characteristic data of the contactless IC card, determines the IC card type of the contactless IC card according to the characteristic data, and performs type switching processing on the contactless IC card when the IC card type is inconsistent with the target type. On the one hand, the contactless IC card corresponding to the old IC card type can be automatically upgraded according to the new target type, which is conducive to improving the working efficiency of the contactless IC card data processing process; on the other hand, the same contactless IC card is shared before and after the type switching process, which is conducive to cost saving.

[0069] In one embodiment, the card reading instruction also includes the reading password of various types of contactless IC cards. Figure 2 As shown, the feature data of the contactless IC card is read based on the card reading instruction, including step S202 and step S204.

[0070] Step S202: Based on the read password, read the stored data of the contactless IC card.

[0071] Step S204: Filtering the characteristic data of the contactless IC card from the stored data according to the preset characteristic data type.

[0072] Among them, the specific definition of characteristic data is as mentioned above, which will not be repeated here. It can be understood that the storage data of the contactless IC card contains characteristic data. The storage data specifically includes card number, user name, user password, balance, points, level, transaction record, application system port number, IC card model, card issuance date, storage sector, software version and software password, etc. Take the case where the contactless IC card is a supermarket membership card as an example. The membership card issued by the supermarket using management software A stores data such as card issuance password (for example, 123456), card reading device (for example, Minghua Aohan M1 card device), port number (for example, USB), card number, user name, user password and balance, among which the card number, user name, user password and balance are characteristic data.

[0073] Furthermore, the read password is the read key. On the one hand, since user information is stored on the contactless IC card, in order to ensure information security, the contactless IC card needs to be encrypted. However, for different types of contactless IC cards, the corresponding read passwords may not be exactly the same. On the other hand, the contactless IC card is usually divided into multiple data storage sectors, each of which contains multiple storage blocks, and each storage block can be used to store different data. For the same contactless IC card, different types of stored data may have different corresponding encryption levels, and the corresponding read passwords may also be different. Based on this, the terminal needs to obtain the read passwords of various types of contactless IC cards while obtaining the card reading instruction, so as to successfully complete the data reading work.

[0074] Specifically, after the terminal obtains the card reading instruction, based on the card reading password set carried in the card reading instruction, the stored data is read based on different card reading passwords in a preset order until the stored data on the contactless IC card is completely read. Then, based on the preset characteristic data type, the stored data containing the type parameter corresponding to the characteristic data type is filtered out from the stored data to obtain the characteristic data of the contactless IC card. For example, if the characteristic data type is the software version, then the storage data whose type parameter is the software version is the characteristic data of the contactless IC card.

[0075] In the above embodiment, the card reading instruction also includes the reading password of each type of contactless IC card. The terminal first reads the stored data of the contactless IC card based on the reading password, and then filters out the characteristic data from the stored data. This can not only avoid missing data, but also ensure the smooth progress of the card reading process, which is conducive to improving the effectiveness of the contactless IC card data processing method.

[0076] In one embodiment, determining the IC card type of the contactless IC card based on the characteristic data includes: determining the sector identifier of the data storage sector used to store the characteristic data based on the characteristic data, and determining the IC card type of the contactless IC card based on the sector identifier and the pre-stored correspondence between the sector identifier and the IC card type.

[0077] Specifically, as mentioned above, the contactless IC card is usually divided into multiple data storage sectors, each of which contains multiple storage blocks, and each storage block can be used to store different data. For contactless IC cards that often need to be upgraded, the characteristic data of the contactless IC cards corresponding to different IC card types can be stored in different storage sectors to improve the convenience of management.

[0078] Take the case where the contactless IC card is a supermarket membership card as an example. The membership card issued by the supermarket contains 15 data storage sectors, each sector has 4 storage blocks, and one storage block can store 16 characters. Based on the membership card issued by the management software A, the card number, user name, balance and user password are stored in different storage blocks of sector 1, and based on the membership card issued by the management software B, the card number, user name, balance and user password are stored in different storage blocks of sector 2. Then, according to the sector identifier of the characteristic data storage sector and the correspondence between the pre-stored sector identifier and the IC card type, the IC card type of the contactless IC card can be determined.

[0079] In the above embodiment, the IC card type of the contactless IC card is determined according to the sector identification of the characteristic data storage sector. The method is simple and convenient, which is conducive to further improving the working efficiency of the contactless IC card data processing method.

[0080] In one embodiment, Figure 3 As shown, the type switching process is performed on the contactless IC card, including step S302 and step S304.

[0081] Step S302: Determine the data storage sector corresponding to the target type according to the target type and the pre-stored correspondence between the sector identifier and the IC card type.

[0082] Specifically, the terminal stores the correspondence between the sector identifier and the IC card type. According to the target type carried in the card reading instruction and the correspondence between the sector identifier and the IC card type, the sector identifier of the data storage sector corresponding to the target type can be determined, and then the data storage sector corresponding to the target type can be determined.

[0083] Step S304: sending the characteristic data of the contactless IC card to the host computer, and after receiving a prompt message from the host computer indicating that the data is correct, writing the characteristic data into a data storage sector corresponding to the target type.

[0084] The host computer is a terminal or server that can obtain the contactless IC card data file and can check the characteristic data based on the file. It can be understood that when the contactless IC card data file is stored in the current terminal, or the current terminal can obtain the contactless IC card data file from the server, the host computer in this embodiment is the current terminal, specifically, other software and hardware modules in the current terminal that are different from the contactless IC card data processing device.

[0085] Specifically, the terminal sends the characteristic data of the contactless IC card to the host computer, which verifies the characteristic data of the contactless IC card one by one based on the contactless IC card data file, and feeds back a prompt message indicating that the data is correct to the terminal after verification. After receiving the prompt message indicating that the data is correct from the host computer, the terminal writes the characteristic data into the data storage sector corresponding to the target type. If the characteristic data is incorrect, the host computer outputs an alarm message to prompt the staff to manually check and update the characteristic data to obtain the updated characteristic data, and feeds back the updated data together with the prompt message indicating that the data is correct to the terminal, and the terminal writes the updated characteristic data into the data storage sector corresponding to the target type. In addition, when writing the characteristic data into the data storage sector corresponding to the target type, the write password can be updated synchronously to improve data security.

[0086] In the above embodiment, the characteristic data in the IC card is first sent to the host computer for verification. After ensuring that the verification is correct, the characteristic data is written into the data storage sector corresponding to the target type. This can ensure the accuracy of the written characteristic data and is conducive to further improving the reliability of the contactless IC card data processing method.

[0087] In one embodiment, sending the characteristic data of the contactless IC card to the host computer includes: sending the characteristic data of the contactless IC card to the host computer through a handle message instruction.

[0088] Among them, a handle is an identifier used to identify an object or item, and can be used to describe a form, resource, control, bitmap, file, etc. A handle message instruction is a program instruction that implements interaction based on a handle message.

[0089] Specifically, the host computer uses the function PostMessage() of the Windows API, defines the communication message number as 5200, defines the operation type readcard, records it in the opertype variable in the changecard.ini file, forms a handle message instruction and sends it to the terminal. After receiving the above handle message instruction, the terminal reads the characteristic data of the contactless IC card, such as the member card number card_id, member balance balance and other information, and pushes these characteristic data back to the host computer through the handle message instruction. Specifically, the characteristic information is stored in the changecard.ini file, and then pushed back to the host computer through PostMessage() and the message number 5200. The host computer reads the changecard.ini file, obtains the corresponding characteristic data, and verifies and updates the characteristic data based on the contactless IC card data file.

[0090] If the data is verified to be correct, the host computer will feedback a prompt message indicating that the data is correct to the terminal, and the terminal will write the characteristic data into the data storage sector corresponding to the target type.

[0091] If the data is incorrect, the host computer will output an alarm message to prompt the staff to manually check and update the feature data, obtain the updated feature data, and define the operation type changecard through PostMessage() and message number 5200, record it in the opertype variable in the changecard.ini file, and form a new handle message instruction together with the prompt information that the data is correct. After receiving the new handle message instruction, the terminal reads the updated feature data carried in the handle message instruction and writes the updated feature data to the data storage sector corresponding to the target type.

[0092] In the above embodiment, data interaction between the terminal and the host computer is realized through handle message instructions, which can improve the security of the data transmission process.

[0093] In one embodiment, before determining the IC card type of the contactless IC card according to the sector identifier and the pre-stored correspondence between the sector identifier and the IC card type, the method further includes: updating the correspondence between the sector identifier and the IC card type. The above steps may be performed before, after, or simultaneously with step S102; the above steps may be performed before, after, or simultaneously with the action of determining the sector identifier of the data storage sector for storing the feature data according to the feature data.

[0094] Specifically, the terminal can update the correspondence between the sector identifier and the IC card type based on the sector identifier and IC card type input by the staff; it can also obtain the latest correspondence between the sector identifier and the IC card type from the host computer after the application environment is updated, and update it to the original correspondence between the sector identifier and the IC card type.

[0095] In the above embodiment, before determining the IC card type of the contactless IC card based on the sector identifier and the pre-stored correspondence between the sector identifier and the IC card type, the correspondence between the sector identifier and the IC card type is updated, which can ensure that the correspondence between the sector identifier and the IC card type covers all IC card types and expand the application scenarios of the contactless IC card data processing method.

[0096] In one embodiment, Figure 4 As shown, after step S106, step S108 is also included: sending feedback information to the upper computer.

[0097] The specific content of the feedback information is not unique, and may include, for example, prompt information on whether the type switching is successful, and / or specific IC card type and feature information.

[0098] Specifically, when the IC card type is inconsistent with the target type, after the contactless IC card is switched, feedback information is sent to the host computer. On the one hand, it is convenient for the host computer to determine whether the contactless IC card type switch is successful; on the other hand, it is convenient for the host computer to perform subsequent processing based on the feedback information, such as updating the contactless IC card data file, and calculating discounts and consumption deductions for the contactless IC card after the type switch based on the cash register software POS front-end system.

[0099] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0100] Based on the same inventive concept, the embodiment of the present application also provides a contactless IC card data processing device for implementing the contactless IC card data processing method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more embodiments of the contactless IC card data processing device provided below can refer to the limitations of the contactless IC card data processing method above, and will not be repeated here.

[0101] In one embodiment, Figure 5 As shown, a non-contact IC card data processing device 500 is provided, comprising a communication module 502, a reading module 504 and a switching module 506. Among them:
