The embodiment of the application provides a bank card binding system, which can be used to perform bank card binding on a target client terminal, and the system includes: a target client terminal and a server of the target bank;

Among them, the target client is used to obtain the bank card binding request, and display the bank selection interface based on the bank card binding request, and the bank selection interface displays the information of multiple banks; receive operations on the bank selection interface to determine the target bank; Call the first interface of the server of the target bank, and send the obtained identity information of the target object to the server of the target bank;

The server of the target bank is used to obtain the identity information of the target object sent by the target client based on the first interface; to obtain the bank card information that matches the identity information of the target object based on the identity information of the target object; to match the identity information of the target object The matching bank card information is sent to the target client;

The target client is also used to display the bank card information interface that matches the identity information of the target object in response to receiving the bank card information that matches the identity information of the target object sent by the server of the target bank; based on the bank card information interface The operation determines the target bank card, and binds the account of the target client to the target bank card.

In the embodiment of the present application, the target client in the bank card binding system interacts with the server of the target bank by calling the interface of the server of the target bank, so that the entire bank card binding can be completed in the target client. There is no need to install other clients, the process of bank card binding is relatively simple, and the efficiency of bank card binding is higher. In addition, the security of the bank card information is relatively high during the interaction between the target client and the server of the target bank.

The embodiment of the present application also provides a bank card binding method, which is used to perform bank card binding on the target client. As shown in Figure 2, the method provided by the embodiment of the present application may include the following steps:

In step 201, the target client obtains a bank card binding request, and displays a bank selection interface based on the bank card binding request, and the bank selection interface displays information of multiple banks.

Due to the speed and convenience of online payment, more and more terminals are equipped with clients that can perform online payments, such as take-out clients, online ticketing clients, and online shopping clients. Before the target object makes online payments through these clients, the account numbers of these clients need to be bound to the target object's own bank card, so that funds can be withdrawn from the account corresponding to the bound bank card during online payment. In this embodiment, the client to be bound with the bank card is used as the target client. On the interface of the target client, an entry for binding a bank card is provided. When the target object triggers the entry for binding the bank card, the target client obtains a bank card binding request. For example, as shown in the target client interface in Figure 3, the option of "binding card immediately" is used as the entrance to bind the bank card. When the target object triggers the option of "binding card immediately", the target client will get the bank card Card binding request.

After the target client obtains the bank card binding request, it displays the bank selection interface based on the bank card binding request, and the bank selection interface displays the information of multiple banks. The target object can select the information corresponding to the bank where the bank card is opened from the information of multiple banks. Bank information refers to information that can accurately determine which bank the bank is, for example, one or more of the name of the bank, the code of the bank, and the icon of the bank. For example, taking the bank’s information as the bank’s name as an example, as shown in Figure 4, there are eight bank names displayed on the target client’s bank selection interface for the target audience to choose from, namely, Agricultural Bank of China, Industrial and Commercial Bank of China, and China For banks, China Construction Bank, Bank of Communications, Hua Xia Bank, China Minsheng Bank, and China Merchants Bank, the target audience can choose the name of the bank that opens their bank card from the names of these eight banks.

In step 202, the target client receives the operation on the bank selection interface and determines the target bank.

When the target object browses the information of multiple banks displayed on the bank selection interface of the target client, he can select the information corresponding to the bank of his bank card, and use the information selected by the target object in the displayed multiple bank information as the target bank Information. When the target object selects the information of the target bank on the bank selection interface of the target client, the target client receives the operation on the bank selection interface.

Optionally, depending on the terminal where the target client is located, operations on the bank selection interface may also be different. For example, when the terminal where the target client is located is a mobile terminal such as a mobile phone or a tablet computer, the operation on the bank selection interface can be for the target object to perform pressure touch on the information of the target bank in the bank selection interface of the target client; When the terminal where the terminal is located is a desktop computer or a portable laptop computer, the operation of the bank selection interface can be the input of the target object through an external device, and the information of the target bank can be selected on the bank selection interface of the target client. For example, the target object can click on the information of the target bank with the mouse to complete the operation on the bank selection interface, or use the keyboard to select the information of the target bank by entering shortcut keys to complete the operation on the bank selection interface.

The target client can determine the information of the target bank based on the operation of the bank selection interface. Since the bank information can accurately determine which bank the bank is, the target client can determine the target bank corresponding to the target bank information according to the acquired target bank information. For example, as shown in Figure 4, the bank selection interface of the target client displays the names of the eight banks: Agricultural Bank of China, Industrial and Commercial Bank of China, Bank of China, China Construction Bank, Bank of Communications, Huaxia Bank, China Minsheng Bank, and China Merchants Bank . When the target object clicks "Bank of China" in the names of these eight banks and triggers the "OK" option, the target client can determine the target bank as "Bank of China".

In step 203, the target client calls the first interface of the server of the target bank, and sends the acquired identity information of the target object to the server of the target bank.

Each bank has the bank’s server, and the bank’s server stores all the relevant information of the bank card issued by the bank, such as the card number of the bank card, the name of the card holder of the bank card, and the card holder of the bank card ID number, etc. After the target client determines the target bank, the server of the target bank can be determined. The client can send information to the bank's server by calling the bank's server interface. After determining the target bank, the target client can send the obtained target object’s identity information to the target bank’s server by calling the first interface of the target bank’s server, so that the target bank’s server can find out whether there is any identity information associated with the target bank’s server. Matching bank card information. The server of the target bank has multiple interfaces, and different interfaces are used to receive different types of information. In this embodiment of the application, the interface used to receive the identity information in the interface of the server of the target bank is used as the first of the server of the target bank. One interface.

It should be noted that the servers of different banks may have different interfaces for receiving identity information. Before the target client calls the first interface of the target bank’s server, it needs to be based on the type of the target bank. Determine the interface used to receive the identity information among the multiple interfaces, and use this interface as the first interface of the server of the target bank.

The identity information of the target object refers to information that can indicate the identity of the target object, for example, one or more of the name of the target object, the ID number of the target object, and the communication number of the target object.

In the embodiment of this application, the method for obtaining the identity information of the target object includes but is not limited to the following two:

Method 1: The target client directly extracts the identity information of the target object from the stored information, thereby obtaining the identity information of the target object. This method occurs when the target client's identity information has been stored in the target client. In other words, before obtaining the bank card binding request, the target client has obtained the target object's identity information and stored it.

Optionally, after obtaining the identity information of the target object from the stored information, the obtained identity information of the target object may be displayed for the target object to check whether the identity information is correct. Optionally, the identity information of the target object may be displayed before the bank selection interface is displayed, or the identity information of the target object may be displayed after the bank selection interface is displayed, which is not limited in the embodiment of the present application. Optionally, the target client displays the identity information of the target object in a desensitized manner, so as to improve the security of the identity information of the target object. Desensitization refers to the process of deforming certain sensitive information through desensitization rules to achieve reliable protection of sensitive privacy data. For example, the desensitization rule is that when displaying the name of the target object, only the last word in the name is displayed, and other words are replaced with "*"; when displaying the ID number of the target object, only the first 3 digits of the ID number are displayed And the last 4 digits, other digits are replaced with "*"; when displaying the communication number of the target object, only the last 4 digits of the communication number are displayed, and other digits are replaced with "*". For example, as shown in (1) in Figure 5, the target client’s interface is desensitized to display the acquired target’s name, target’s ID number, and target’s communication number, and other identity information for the target to check .

When the target object checks that the identity information is correct, the "OK" option in the interface can be triggered. At this time, it means that the target client's identity information obtained from the stored information is correct, and it can be executed according to the obtained identity information. Next steps. When the target object checks the identity information incorrectly, the "return" option in the interface can be triggered. At this time, it means that the target object's identity information obtained by the target client is incorrect, and the target object's identity information needs to be re-acquired to perform the follow-up step. Optionally, when the identity information of the target object obtained according to the first method is incorrect, the identity information of the target object may be obtained again according to the second method.

Method 2: The target client displays the identity information input box for the target object to input identity information. The target client obtains the identity information of the target object according to the identity information input by the target object. This method occurs when the identity information of the target object is not stored in the target client, or when the identity information of the target object obtained according to the first method is wrong. Optionally, the identity information input box may be displayed before the bank selection interface is displayed, or the identity information input box may be displayed after the bank selection interface is displayed, which is not limited in this embodiment of the application. For example, as shown in (2) in Figure 5, the identity information input box is displayed on the interface of the target client. When the target object enters the identity information such as name, ID number, and communication number in the identity information input box, the "OK" is triggered ”Option, the target client obtains the identity information of the target object.

It should be noted that when only part of the identity information of the target object is stored in the target client, method one can be used to obtain part of the stored identity information of the target object, and then method two can be used to obtain other identity information of the target object. For example, suppose that the identity information required in the process of binding a bank card is the name, ID number and communication number, and only the name and ID number of the target object are stored in the target client. At this time, the name of the target object can be obtained according to method 1. And the ID number, and then obtain the communication number entered by the target object according to the second method.

In step 204, the server of the target bank obtains the identity information of the target object based on the first interface.

The server of the target bank has multiple interfaces, and different interfaces are used to receive different types of information. In this embodiment of the application, the interface for receiving identity information in the interface of the server of the target bank is used as the first interface of the server of the target bank.

The server of the target bank obtains the identity information of the target object sent by the target client based on the first interface, for example, the name of the target object, the ID number of the target object, and the communication number of the target object. Optionally, after obtaining the identity information of the target object, the server of the target bank may search for the existence of bank card information matching the identity information according to the obtained identity information of the target object. For example, when the identity information of the target object is the ID number, the server of the target bank searches for all bank card related information stored for whether there is bank card information matching the ID number. Bank card information refers to information related to each bank card itself, such as the card number of the bank card, the type of the bank card, the validity period of the bank card, the security code of the bank card, and so on. Optionally, the search result of searching whether there is bank card information matching the identity information of the target object includes the following two types:

Search result 1: There is no bank card information that matches the identity information of the target object. The reason for this search result may be: the determined target bank is wrong, and/or the obtained target object’s identity information is wrong. In other words, there is no bank card of the target object in the target bank, and/or the identity information of the target object is entered incorrectly. For example, the target object does not have a bank card of Bank of China, but Bank of China is selected in the bank selection interface. In this case, the search result is that there is no bank card information that matches the identity information of the target object; for another example, the target object The identity information of is the identity document number, but the entered identity document number is incorrect. In this case, the search result is also that there is no bank card information matching the target object’s identity information.

Under this search result, the server of the target bank can send a response to the target client that the matching fails. After the target client receives the response of the matching failure, it can redisplay the bank selection interface for the target object to select the target bank again, or to obtain the identity information of the target object again.

Search result 2: There is bank card information that matches the identity information of the target object. Under such search results, step 205 is executed.

In step 205, the server of the target bank obtains bank card information matching the identity information of the target object based on the identity information of the target object.

When there is bank card information matching the identity information of the target object, the server of the target bank obtains all bank card information that matches the identity information of the target object based on the identity information of the target object. For the same target object, the target object may have one or more bank cards issued by the target bank, so all the bank card information obtained that matches the target object’s identity information may correspond to one or more bank cards Bank card information. The bank card information corresponding to each bank card may include one or more types of information such as the card number of the bank card, the type of the bank card, the validity period of the bank card, and the security code of the bank card.

In step 206, the server of the target bank sends the bank card information matching the identity information of the target object to the target client.

The bank card information that matches the identity information of the target object contains one or more bank card information, and each bank card information contains one or more pieces of information. The information of any bank card may include information that can uniquely represent the bank card, such as the card number of the bank card, the security code of the bank card, etc., and information that cannot uniquely represent the bank card, for example, the The card type of the bank card, the validity period of the bank card, etc. In the process that the server of the target bank sends the bank card information that matches the identity information of the target object to the target client, it can send all the bank card information that matches the identity information of the target object obtained to the target client. Only one type of bank card information that can uniquely represent a certain bank card among all the bank card information can be sent to the target client. For example, only the card numbers of all bank cards in all bank card information are sent to the target client, and the card number of each bank card uniquely represents a bank card.

Optionally, the server of the target bank may encrypt the bank card information before sending the bank card information matching the identity information of the target object to the target client. Then, the encrypted bank card information that matches the identity information of the target object is sent to the target client. The embodiment of the present application does not limit the encryption method, for example, symmetric encryption. This process can increase the security of the bank card information during transmission.

Optionally, after the server of the target bank sends the bank card information matching the identity information of the target object to the target client, the method further includes: the server of the target bank sends the first verification code to the terminal of the target object; the target client receives After the bank card information that matches the identity information of the target object, the verification code input box is displayed; the target client obtains the second verification code entered by the target object in the verification code input box; the target client calls the second interface of the server of the target bank , Send the second verification code to the server of the target bank; the server of the target bank obtains the second verification code sent by the target client based on the second interface. Among them, the terminal of the target object refers to a terminal that can verify the identity of the target object, for example, the terminal where the communication number of the target object is located. Here, the interface for receiving the verification code in the interface of the server of the target bank is used as the second interface of the server of the target bank. The second interface may be the same as the first interface or different from the first interface, which is not limited in the embodiment of the present application.

It should be noted that the servers of different banks may have different interfaces for receiving verification codes. Before the target client calls the second interface of the server of the target bank, it needs to be based on the type of the target bank. Determine the interface for receiving the verification code from the multiple interfaces of, and use this interface as the second interface of the server of the target bank.

After obtaining the second verification code, the server of the target bank checks whether the first verification code is consistent with the second verification code. In response to the first verification code being consistent with the second verification code, the server of the target bank sends a response of successful verification to the target client. In response to the first verification code being inconsistent with the second verification code, the server of the target bank may send a response that the verification fails to the target client. Based on the response of the verification failure, the target client may display the verification code input box again, or directly return to the first interface of the target client, which is not limited in this embodiment of the application.

In step 207, the target client, in response to receiving the bank card information matching the target object's identity information, displays a bank card information interface matching the target object's identity information.

After receiving the bank card information matching the target object's identity information returned by the target bank's server, the target client displays the bank card information interface matching the target object's identity information. In the displayed bank card information interface, the bank card information matching the identity information of the target object is displayed. When the server of the target bank sends all the bank card information obtained to the target client, all the bank card information is displayed on the bank card information interface; when the server of the target bank only displays all the bank card information uniquely When one type of bank card information of a certain bank card is sent to the target client, only that type of bank card information is displayed on the bank card information interface. On the bank card information interface matching the identity information of the target object, the bank card information belonging to the same bank card is displayed in association with each other. Optionally, when the target client displays the bank card information matching the identity information of the target object in a list, the bank card information of the same bank card is displayed in the same row of the list. For example, as shown in Figure 6, the bank card information of bank card 1 is displayed on the first line of the list, the bank card information of bank card 2 is displayed on the second line of the list, and the bank of bank card 3 is displayed on the third line of the list. Card information, the bank card information of bank card 4 is displayed in the fourth row of the list.

Optionally, after receiving the successful verification response sent by the server of the target bank, the target client may respond to receiving bank card information matching the identity information of the target object and receiving a successful verification response, and display the same The identity information matches the bank card information interface.

Optionally, when the bank card information that matches the target object’s identity information received by the target client is encrypted bank card information, the target client first decrypts the encrypted bank card information, and then displays it with the target object The identity information matches the bank card information interface.

Optionally, the method for the target client to display the bank card information interface matching the target object’s identity information is: the target client scrambles the reference position in the bank card information matching the target object’s identity information, and then displays the scrambled The subsequent bank card information interface that matches the target object’s identity information can improve the security of the bank card information. Depending on the type of bank card information, the situation of scrambling the reference location in the bank card information is also different. For example, for the card number of a bank card, the reference position may refer to the position corresponding to the fourth to tenth digit of the card number; for the security code of a bank card, the reference position may refer to the second digit corresponding to the security code The location and so on. The embodiment of the present application does not limit the scrambling method. For example, the number of the reference position is replaced with "*".

In step 208, the target client determines the target bank card based on the operation on the bank card information interface, and binds the account of the target client to the target bank card.

The operation on the bank card information interface may refer to the target object's selection operation of the target bank card information on the bank card information interface, and the target bank card can be determined based on the selection operation on the target bank card information. Specifically, the target object selects any bank card information in the bank card information displayed on the bank card information interface. Since the bank card information belonging to the same bank card is displayed in association with each other in the bank card information interface, it is selected according to the target object The bank card information can determine the bank card to be bound corresponding to the bank card information, that is, the target bank card. For example, as shown in Figure 6, when the bank card information selected by the target object on the bank card information interface is card number 2, it can be determined that the target bank card is bank card 2. After determining the target bank card, the target client binds the account of the target client with the target bank card. This process does not require the target object to memorize complex information such as the card number of the target bank card, which improves the target object's bank card binding experience, and the efficiency of bank card binding is higher.

Optionally, the target client binds the account of the target client to the target bank card, including: the target client calls the third interface of the server of the target bank, and sends a contract request to the server of the target bank. The contract request includes the target client's Account number and target bank card information; the server of the target bank obtains the signing request based on the third interface, and then signs the account of the target client with the target bank card based on the signing request; in response to the successful signing, the server of the target bank sends to the target client Instruction for successful signing: In response to receiving the instruction for successful signing, the target client binds the account of the target client to the target bank card. Wherein, the third interface of the server of the target bank refers to an interface of the server of the target bank for receiving a contract request. The third interface may be the same as the first interface and/or the second interface, or may be different from the first interface and the second interface, which is not limited in the embodiment of the present application.

It should be noted that the servers of different banks may have different interfaces for receiving contract requests. Before the target client calls the third interface of the target bank’s server, it needs to be based on the target bank’s server type. Determine the interface used to receive the contract request among the multiple interfaces of, and use this interface as the third interface of the server of the target bank.

Specifically, the process of binding the account of the target client to the target bank card includes two steps: signing and binding. Among them, the contract is performed in the server of the target bank; the binding is performed in the target client. Signing refers to the signing of a contract between the account of the target client and the target bank card. The contract is used to stipulate that funds can be withdrawn from the account of the target bank card when online payments are made based on the account of the target client. Optionally, after the signing is successful, the instruction for successful signing sent by the server of the target bank to the target client includes the signing agreement number, and the signing agreement number is used to indicate that the signing is successful. After obtaining the instruction for successful signing, the target client binds the account of the target client with the target bank card. After the two steps of signing and binding, when online payment is based on the target client, funds can be withdrawn from the account of the target bank card bound to the account of the target client.

In the process of bank card binding, related technologies display the entrances of multiple banks on the interface of the target client, and jump to the client of the target bank or the webpage of the target bank based on the trigger instruction of the entrance of the target bank. On the client side of the target bank or the interface of the webpage, the bank card list of the target object is displayed. Then, according to the selected instruction of the target bank card in the bank card list, jump to the target client, and bind the account of the target client with the target bank card in the target client. In this process, it involves the jump between the target client and the client of the target bank or the jump between the target client and the webpage of the target bank, which is not friendly to users who have not registered a bank account. The bank card is bound The process is more complicated, and the efficiency of bank card binding is low. In addition, the security of bank card information is low during the jump process between the client and the client or the client and the webpage. In the embodiment of this application, after the target bank’s information in the bank selection interface of the target client is triggered, the interface of the target bank’s server is called, the identity information of the target object is sent to the target bank’s server, and then the target client’s interface The bank card information that matches the identity information returned by the server of the target bank is displayed in, and then the target bank is determined in the bank card information, and the account number of the target client is bound to the target bank card. This process only involves the target client. There is no need to register a bank account, no need to jump between different clients, and no need to jump between the client and the web page. The process of bank card binding is relatively simple. The binding efficiency is high. In addition, the security of the bank card information is high when the target client interacts with the bank's server by calling the bank's server interface.

In the embodiment of this application, the target client calls the interface of the server of the target bank, sends the identity information of the target object to the server of the target bank, determines the target bank card based on the bank card information returned by the server of the target bank, and then transfers the target customer The account number of the terminal is bound to the target bank card. The target client interacts with the server of the target bank by calling the interface of the server of the target bank, so that the entire bank card binding process can be completed in the target client client, without installing other clients, bank cards The binding process is relatively simple, and the efficiency of bank card binding is high. In addition, the security of the bank card information is relatively high during the interaction between the target client and the server of the target bank.
