[0054] The core of this application is to provide a data card reading and writing method, which can effectively improve the data card reading and writing efficiency and enhance the user experience; another core of this application is to provide another data card reading and writing method, data card reading and writing device, computer device and computer-readable storage medium, all of which have the above beneficial effects.

[0055] In order to describe the technical solutions in the embodiments of this application more clearly and completely, the following will introduce the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0056] The embodiments of this application provide a data card reading and writing method.

[0057] Please refer to Figure 2 , Figure 2 which is the flowchart of a data card reading and writing method provided by this application. This data card reading and writing method is applied to the server and may include:

[0058] S101: Obtain the data card status information from the client according to the data card operation command;

[0059] This step aims to realize the acquisition of the data card status information, which is the current status of the data card, including the status of the card to be written and the status of the card to be read. The status of the card to be written indicates that a write operation needs to be performed on the data card currently, and the status of the card to be read indicates that a read operation needs to be performed on the data card currently.

[0060] In the embodiments of this application, the data card is also called an electronic data card and can support the reading and writing of electronic data. For example, the data card includes, but is not limited to, magnetic cards, bar code cards, integrated circuit (IC) cards, and identification (ID) cards.

[0061] In some embodiments, when the server receives a data card operation command, it can obtain the data card status information from the client according to the data card operation command. Here, the client refers to a local client directly connected to the card reader, which can communicate with the server through a connection to achieve data communication; the server connects to the client through a network, which can be a local area network or a wide area network, such as the Internet (such as an edge network, a cloud network, etc.). When the server connects to the client through the Internet, the server is then a remote server, and data card reading and writing are achieved based on the remote connection. For example, in a cashier system, the local client establishes a connection with the remote server to achieve IC card reading and writing operations. The remote server can obtain the status information of the IC card from the local client when receiving the data card operation command, and then achieve the reading and writing operations of the IC card according to the status information. In some embodiments, the remote client can also operate on the remote server, thereby affecting the data card reading and writing process.

[0062] Among them, the data card operation command is used to notify the server that it is necessary to perform reading and writing operations on the data card. Of course, whether it is a read operation or a write operation is not determined thereby, and it needs to be further determined by obtaining the data card status information.

[0063] It should be noted that the client involved in the embodiments of the present application can be provided by a terminal device, and the server involved can be provided by a server. Among them, the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, Content Delivery Network (CDN), and big data and artificial intelligence platforms. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected through wired or wireless communication methods, which are not limited in the embodiments of the present application.

[0064] In an embodiment of the present application, obtaining the data card status information from the client according to the data card operation command may include: reading and obtaining the data card status information from the second storage directory of the client according to the data card operation command; among them, the data card status information is read and obtained from the data card by the client after receiving the data card connection information.

[0065] The embodiment of the present application provides a method for implementing the reading of data card status information, that is, the server reads the local storage of the client, that is, the above-mentioned second storage directory, to obtain the data card status information. When the client senses the data card connection information, that is, when it senses that a data card is inserted (or connected), it reads the information of the data card to determine its state. For example, if the data card is an empty card, it means that the data card is in the state of waiting to be written, and if the data card is not an empty card, it means that the data card is in the state of waiting to be read. Thus, after obtaining the data card status information, it can be stored in the local second storage directory for the server to read.

[0066] Of course, the above-mentioned second storage directory is only an implementation manner for storing data card status information provided by this preferred embodiment, and is not unique. Any storage medium can be selected to implement the storage of data card status information, and the present application does not make any limitations in this regard.

[0067] In an embodiment of the present application, before obtaining the data card status information from the client according to the data card operation command, it may further include: receiving the data card operation command sent by the client based on the data card connection information.

[0068] The embodiment of the present application provides a method for obtaining a data card operation command, that is, the data card operation command can be sent by the client to the server so that the server can obtain the data card status information based on the data card operation command. As described above, when the client senses the data card connection information, it can determine the data card status information by reading the data card and store it in the second storage directory. Based on this, it can simultaneously send a data card operation command to the server to notify the server to obtain the data card status information.

[0069] In an embodiment of the present application, before obtaining the data card status information from the local client according to the data card operation command, it may further include: responding to the data card operation command at a preset time interval.

[0070] The embodiment of the present application provides another method for obtaining a data card operation command. A timing mechanism can be set for the server so that the server can respond to the data card operation command at a preset time interval, thereby implementing the acquisition of data card status information. Among them, the specific value of the preset time interval does not affect the implementation of this technical solution and can be set by those skilled in the art according to the actual situation. The present application does not make any limitations in this regard.

[0071] It can be understood that one of the above two implementation manners can be selected by those skilled in the art according to actual needs for setting, or both implementation manners can be set at the same time. The present application does not make any limitations in this regard.

[0072] S102: when the data card status information is a card to be written, obtaining target data, and sending the target data to the client, so that the client writes the target data into the data card;

[0073] This step is intended to implement the write operation of the data card. When the data card status information is a card to be written, the server can obtain the target data (i.e., the data information that needs to be written to the data card) and send it to the client; further, the client can send the target data to the data card to implement the client-based data card write operation. Among them, the implementation process of the server obtaining the target data may include: the server initiates a data acquisition request to its corresponding client (i.e., the remote client) based on the data card status information, and the remote client displays the prompt information of the request to obtain the target data on the front-end interface, so that the technician can enter the target data on the front-end interface according to the prompt information, and then the remote client feeds back the target data to the server, thereby realizing the acquisition of the target data on the server. For example, the target data includes but is not limited to user information, financial information, and permission information related to the data card.

[0074] S103: When the data card status information is a card to be read, read the first storage directory of the client to obtain read data; wherein the read data is obtained by the client reading the data card.

[0075] This step is intended to implement the data card read operation. As described above, after the client senses the data card connection information, it can determine the data card status information by reading the data card and store it in the second storage directory. At the same time, when the data card status information is a card to be read, the client can simultaneously read the data information stored in the data card, obtain the read data, and store it locally, that is, store it in the first storage directory. Therefore, when the data card status information is a card to be read, the server can directly read the first storage directory of the client to obtain the read data of the data card. Of course, the above-mentioned first storage directory and the above-mentioned second storage directory can be the same storage directory or different storage directories, and this application does not limit this. After obtaining the read data, the server can store the read data in a specific storage location, such as a database or blockchain, and can also perform corresponding services based on the read data, such as handling banking services.

[0076] In one embodiment of the present application, after reading the first storage directory of the client and obtaining the read data, the method may further include: sending a data read success instruction to the client, so that the client modifies the data card status information according to the data read success instruction.

[0077] The data card reading and writing method provided by the embodiments of the present application aims to implement the function of updating the status information of the data card. After the server obtains the read data, it can send a data reading success instruction to the client. Thus, the client can modify the data card status information from the card to be read to the card read successfully according to the data reading success instruction. Of course, when the server fails to obtain the read data successfully from the client, it can also feedback a data reading failure instruction to the client. Thus, the client can modify the data card status information from the card to be read to the card read failed according to the data reading failure instruction, so that the technical personnel can timely know the read data result of the data card. In addition, in the case of a card reading failure, the client can further output a card reading failure prompt to facilitate the technical personnel to trace the abnormality in time.

[0078] It can be seen that in the data card reading and writing method provided by the present application, the server establishes a connection with the client. When a write operation needs to be performed on the data card, the server sends the target data to the client, and the client writes the target data into the data card; when a read operation needs to be performed on the data card, the client directly reads the data card to obtain the read data and stores it locally, so that the server can directly read the local storage of the client to obtain the read data. Thus, the reading and writing operations of the data card are directly implemented based on the local client without opening the remote computer port for data card reading and writing, effectively improving the data card reading and writing efficiency and further improving the user experience.

[0079] The embodiments of the present application provide another data card reading and writing method.

[0080] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of a data card reading and writing method provided by the present application. The data card reading and writing method is applied to the client and may include:

[0081] S201: When receiving the data card connection information, obtain the data card status information;

[0082] This step aims to obtain the data card status information. When the client senses the data card connection information, that is, when it senses that a data card is inserted (connected), it can read the information of the data card to determine its status. Thus, the data card status information is obtained. Further, the client can locally store the data card status information for the server to read, and then perform corresponding reading and writing operations on the data card.

[0083] S202: When the data card status information is the card to be read, read the data card to obtain the read data and store the read data in the first storage directory for the server to read;

[0084] This step aims to implement the read operation of the data card. When the status information of the data card is waiting to be read, the client can directly read the data card, obtain the corresponding read data, and store it locally, that is, store it in the first storage directory for the server to read.

[0085] S203: When the status information of the data card is waiting to be written, in the case of receiving the target data sent by the server, write the target data into the data card.

[0086] This step aims to implement the write operation of the data card. When the status information of the data card is waiting to be written, the server will send the target data to the client according to the status information of the data card. The target data is the data that needs to be written into the data card. Thus, the client can write the received target data into the data card, thereby completing the write operation of the data card.

[0087] In an embodiment of the present application, the above-mentioned writing the target data into the data card may include: writing the target data into the data card through a preset reading and writing tool; and the above-mentioned reading the data card to obtain the read data may include: reading the data card through a preset reading and writing tool to obtain the read data. For example, the client may store a preset reading and writing tool, and the preset reading and writing tool operates on the SerialPort to achieve data reading and writing.

[0088] It can be understood that the data card reading and writing method provided by the embodiments of the present application aims to implement the reading and writing operations of the data card through the client. When performing the reading and writing operations on the data card through the client, specifically, a preset reading and writing tool in the client can be used to perform the reading and writing operations on the data card. Thus, when performing the write operation on the data card, the target data can be written into the data card by running the preset reading and writing tool; when performing the read operation on the data card, the read data can be obtained by running the preset reading and writing tool to read the data card. Of course, the setting and updating of the above-mentioned data card status information on the client can also be achieved through the preset reading and writing tool.

[0089] Among them, a shared folder can be created on the client to store the preset reading and writing tool in the shared folder. Further, the client can run the preset reading and writing tool through a corresponding plugin. In addition, the data card status information obtained by the client and the read data obtained when performing the read operation on the data card can be stored in different storage directories in the shared folder respectively.

[0090] It should be noted that the above-mentioned preset reading and writing tool integrates both reading and writing functions. However, in some embodiments, it can also be divided into a preset reading tool and a preset writing tool. Among them, the preset reading tool is dedicated to implementing the function of reading data, and the preset writing tool is dedicated to implementing the function of writing data.

[0091] In one embodiment of the present application, after writing the target data to the data card, the following steps may further be included: obtaining the write data result feedback by the data card; modifying the data card status information according to the write data result.

[0092] The data card reading and writing method provided by the embodiments of the present application can implement the update function of the data card status information. After writing the target data to the data card, the data card will feedback the write data result to the client, such as successful card writing or failed card writing. Thus, the client can modify the data card status information according to the write data result. When the write data result is failed card writing, the data card status information can be changed from to-be-written card to failed card writing, and when the write data result is successful card writing, the data card status information can be changed from to-be-written card to successful card writing, so that technicians can timely know the write data result of the data card. In addition, in the case of failed card writing, the client can further output a failed card writing prompt for technicians to timely trace the anomaly.

[0093] It can be seen that for the data card reading and writing method provided by the present application, the server establishes a connection with the client. When a write operation needs to be performed on the data card, the server sends the target data to the client, and the client writes the target data to the data card; when a read operation needs to be performed on the data card, the client directly reads the data card to obtain the read data and stores it locally, so that the server can directly read the local storage of the client to obtain the read data. Thus, the reading and writing operations of the data card are directly implemented based on the local client without opening the remote computer port for data card reading and writing, effectively improving the data card reading and writing efficiency and further improving the user experience.

[0094] Based on the above embodiments, taking an IC card as an example, the embodiments of the present application provide an IC card reading and writing method.

[0095] Please refer to Figure 4 and Figure 5 , Figure 4 which is a flowchart of the reading and writing of an IC card provided by the present application. Among them, the server is a remote server (such as the server of a cash register system), and the client is a local client (such as the client of a cash register system); Figure 5 which is a timing diagram of an IC card reading and writing method provided by the present application. Among them, the S disk shared folder is set on the local client, and the local client is remotely connected to the server (remote server).

[0096] For example, when remotely connecting to a retail POS, a shared folder can be added to the local client. A tool for reading and writing the IC card (preset reading and writing tool) is set in the shared folder, acting as a bridge between the cash register system and the card reader. On this basis, the implementation process of the IC card reading and writing method is as follows:

[0097] (1) Write all parameter information (parameter information of the serial port for inserting the IC card) into the configuration file \\tsclient\s\SerialPort\Setting.ini under the shared folder. Among them, the "SerialPort" directory is manually created in advance, and during the actual operation, the client plugin will automatically create it; "Setting.ini" is the name of the configuration file.

[0098] (2) Transfer the read-write tool to the \\tsclient\s\SerialPort directory (the storage directory for storing the read-write tool, which can be regarded as the third storage directory). If the read-write tool has been transferred to the local client, there is no need to transfer it again.

[0099] (3) The cloud client (the client corresponding to the server, that is, the remote client) plugin runs the read-write tool, and the read-write tool reads the configuration file and restores all parameter information.

[0100] (4) Execute the serial port read operation through the read-write tool, and save the read result in S:\SerialPort\result.ini, and then notify the remote server to read \result.ini.

[0101] (5) If the status value of result.ini is 3: waiting to read card information, the remote server continues to read \\tsclient\s\SerialPort\result.ini, obtains the read data, and displays it on the remote client. At the same time, it notifies the local client that the data reading is successful, and the read-write tool rewrites the status value of result.ini to 4: reading card information successful.

[0102] (6) If the status value of result.ini is 0: waiting to make a card, the remote server obtains the data to be written (corresponding to the target data above) and feeds it back to the local client. The local client writes the data to be written into the IC card through the read-write tool, and rewrites the status value of result.ini to 1: making card successful.

[0103] Among them, the status of result.ini:

[0104] 0: waiting to make a card, 1: making card successful, 2: making card failed, 3: waiting to read card information, 4: reading card information successful, 5: reading card information failed.

[0105] In addition, the remote server can also poll the results of the S drive every 3 to 5 seconds, and notify the read-write tool in the shared folder to perform read and write operations when the status value is 3 or 0. In the above example, the storage directory where result.ini is located is both the first storage directory and the second storage directory.

[0106] It can be seen that in the method for reading and writing an IC card provided by the embodiments of the present application, a connection is established between the server and the client. When a write operation needs to be performed on the IC card, the server sends the target data to the client, and the client writes the target data into the IC card. When a read operation needs to be performed on the IC card, the client directly reads the IC card to obtain the read data and stores it locally, so that the server can directly read the local storage of the client to obtain the read data. Thus, the read and write operations of the IC card are directly implemented based on the local client, without the need to open a remote computer port for IC card reading and writing, effectively improving the IC card reading and writing efficiency and further improving the user experience.

[0107] The embodiments of the present application provide a data card reading and writing device.

[0108] Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of a data card reading and writing device provided by the present application. The data card reading and writing device is applied to a server and may include:

[0109] A server information acquisition module 1, configured to acquire data card status information from a client according to a data card operation command;

[0110] A server card writing module 2, configured to acquire target data and send the target data to the client when the data card status information is to-be-written, so that the client writes the target data into the data card;

[0111] A server card reading module 3, configured to read a first storage directory of the client to obtain read data when the data card status information is to-be-read; wherein, the read data is obtained by the client reading the data card.

[0112] It can be seen that in the data card reading and writing device provided by the embodiments of the present application, a connection is established between the server and the client. When a write operation needs to be performed on the data card, the server sends the target data to the client, and the client writes the target data into the data card.
