[0097] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0098] At present, due to the speed and convenience of online payment, more and more people choose to consume through online payment. In online payment scenarios, users usually need to bind the account of online payment-related applications with the user's bank card, and then withdraw funds from the corresponding account of the bank card when payment operations are required. Therefore, how to bind a bank card is the key to affecting the online payment experience.

[0099] In this regard, the embodiments of the present application provide a system, method, device, equipment and storage medium for bank card binding, please refer to Figure 1 , which shows a schematic diagram of an implementation environment of the method provided in an embodiment of the present application. The implementation environment may include: a terminal 11 and a server 12.

[0100] Among them, the terminal 11 is installed with a client that can make online payments. Before the client makes online payments, the method provided in the embodiment of the present application can be applied to bind the client's account with a bank card. The terminal 11 can obtain the identity information of the target object and the account information of the client, and then send the identity information of the target object and the account information of the client to the server 12 for storage. The server 12 can obtain the bank card information of the target object, and then send the bank card information to the terminal 11 for storage. Of course, the identity information of the target object and the account information of the client can also be stored on the terminal 11, and the bank card information of the target object can also be stored on the server 12. Therefore, when bank card binding is required, the method provided in the embodiment of the present application can be applied to achieve the binding of the client's account with the bank card.

[0101] Optionally, the terminal 11 can be any electronic product that can interact with the user through one or more methods such as a keyboard, a touch pad, a touch screen, a remote control, voice interaction or a handwriting device, such as a PC (Personal Computer), a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a wearable device, a handheld computer PPC (Pocket PC), a tablet computer, a smart car machine, a smart TV, a smart speaker, etc. The server 12 can be a server, a server cluster composed of multiple servers, or a cloud computing service center. The terminal 11 establishes a communication connection with the server 12 through a wired or wireless network.

[0102] Those skilled in the art should understand that the above-mentioned terminal 11 and server 12 are only examples, and other existing or future terminals or servers that are applicable to the present application should also be included in the protection scope of the present application and are included here by reference.

[0103] The embodiment of the present application provides a bank card binding system, which can be used to bind a bank card on a target client, and the system includes: a target client and a server of a target bank;

[0104] The target client is used to obtain a bank card binding request, display a bank selection interface based on the bank card binding request, and display information of multiple banks on the bank selection interface; receive an operation on the bank selection interface and determine a target bank; call a first interface of a server of the target bank and send the obtained identity information of the target object to the server of the target bank;

[0105] 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; based on the identity information of the target object, obtain the bank card information matching the identity information of the target object; and send the bank card information matching the identity information of the target object to the target client;

[0106] The target client is also used to respond to bank card information matching the identity information of the target object sent by the server of the target bank, and display a bank card information interface matching the identity information of the target object; determine the target bank card based on operations on the bank card information interface, and bind the target client's account to the target bank card.

[0107] In the embodiment of the present application, in the bank card binding system, 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 alone, without installing other clients. The bank card binding process is relatively simple and the bank card binding efficiency is high. In addition, the security of bank card information is relatively high during the interaction between the target client and the server of the target bank.

[0108] The embodiment of the present application also provides a bank card binding method, which is used to bind a bank card on a target client. Figure 2 As shown, the method provided in the embodiment of the present application may include the following steps:

[0109] 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, where information of multiple banks is displayed.

[0110] Due to the speed and convenience of online payment, more and more terminals are installed with clients capable of online payment, such as takeaway clients, online ticket purchase clients, online shopping clients, etc. Before the target object makes an online payment through these clients, it is necessary to bind the account of these clients with the target object's own bank card, so that when making an online payment, funds can be withdrawn from the account corresponding to the bound bank card. In this embodiment, the client to which the bank card is to be bound is used as the target client. On the interface of the target client, an entry for binding the 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, Figure 3 As shown in the target client interface, the "Bind card immediately" option is used as the entry for binding the bank card. When the target object triggers the "Bind card immediately" option, the target client obtains the bank card binding request.

[0111] After the target client obtains the bank card binding request, the bank selection interface is displayed based on the bank card binding request. The bank selection interface displays information of multiple banks. The target object can select the information corresponding to the bank where his bank card is opened from the information of multiple banks. The bank information refers to the information that can accurately determine which bank the bank is, such as one or more of the bank's name, bank code, and bank icon. For example, taking the bank information as the bank's name, such as Figure 4 As shown, on the bank selection interface of the target client, eight bank names are displayed for the target object to choose from, namely, Agricultural Bank of China, Industrial and Commercial Bank of China, Bank of China, China Construction Bank, Bank of Communications, Hua Xia Bank, China Minsheng Bank and China Merchants Bank. The target object can choose the name of the bank where his bank card is opened from these eight banks.

[0112] In step 202, the target client receives an operation on the bank selection interface and determines a target bank.

[0113] When the target object browses the information of multiple banks displayed on the bank selection interface of the target client, the target object can select the information corresponding to the bank where the bank card is opened, and the information selected by the target object from the displayed information of multiple banks is used as the information of the target bank. 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.

[0114] Optionally, the operation on the bank selection interface may be different depending on the terminal where the target client is located. 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 may be that the target object performs pressure touch on the target bank's information in the bank selection interface of the target client; when the terminal where the target client is located is a desktop computer or a portable laptop computer, the operation on the bank selection interface may be that the target object selects the target bank's information in the bank selection interface of the target client through input from an external device. For example, the target object may click on the target bank's information with a mouse to complete the operation on the bank selection interface, or may select the target object's information by inputting shortcut keys on the keyboard to complete the operation on the bank selection interface.

[0115] The target client can determine the target bank information based on the operation on 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 based on the acquired target bank information. For example, Figure 4 As shown in the figure, the bank selection interface of the target client displays the names of eight banks, namely, Agricultural Bank of China, Industrial and Commercial Bank of China, Bank of China, China Construction Bank, Bank of Communications, Hua Xia Bank, China Minsheng Bank and China Merchants Bank. When the target object clicks "Bank of China" among the names of these eight banks and triggers the "Confirm" option, the target client can determine that the target bank is "Bank of China".

[0116] 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.

[0117] Each bank has its own server, and the server of the bank stores relevant information of all bank cards issued by the bank, such as the bank card number, the name of the bank card holder, the ID number of the bank card holder, etc. After determining the target bank, the target client can determine the server of the target bank. The client can send information to the server of the bank by calling the interface of the bank's server. After determining the target bank, the target client can send the acquired identity information of the target object to the server of the target bank by calling the first interface of the server of the target bank, so that the server of the target bank can search whether there is bank card information matching the identity information. In an embodiment of the present application, the interface of the target bank's server for receiving the identity information of the target object sent by the target client is used as the first interface of the server of the target bank.

[0118] The target object's identity information refers to information that can indicate the target object's identity, for example, one or more of the target object's name, the target object's identity document number, and the target object's communication number.

[0119] In the embodiment of the present application, the methods for obtaining the identity information of the target object include but are not limited to the following two methods:

[0120] Method 1: The target client directly extracts the target object's identity information from the stored information, thereby obtaining the target object's identity information. This method occurs when the target object's identity information is already stored in the target client. In other words, before obtaining the bank card binding request, the target client has already obtained the target object's identity information and stored it.

[0121] Optionally, after obtaining the identity information of the target object from the stored information, the obtained identity information of the target object can be displayed for the target object to verify whether the identity information is correct. Optionally, the identity information of the target object can be displayed before displaying the bank selection interface, or after displaying the bank selection interface, which is not limited in the embodiments of the present application. Optionally, the target client displays the identity information of the target object in a desensitized manner to improve the security of the identity information of the target object. Desensitization refers to the process of deforming data of 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 by "*"; when displaying the identity document number of the target object, only the first 3 digits and the last 4 digits of the identity document number are displayed, and other digits are replaced by "*"; 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 by "*", etc. For example, such as Figure 5As shown in (1), the target object's name, the target object's ID number, the target object's communication number and other identity information are displayed in an anonymized manner on the target client's interface for the target object to check.

[0122] When the target object verifies that the identity information is correct, the "OK" option in the interface can be triggered, which means that the identity information of the target object obtained by the target client from the stored information is correct, and the subsequent steps can be performed according to the obtained identity information. When the target object verifies that the identity information is incorrect, the "Return" option in the interface can be triggered, which means that the identity information of the target object obtained by the target client is incorrect, and the identity information of the target object needs to be re-obtained before the subsequent steps can be performed. Optionally, when the identity information of the target object obtained according to method one is incorrect, the identity information of the target object can be re-obtained according to method two.

[0123] Method 2: The target client displays an identity information input box for the target object to input identity information. The target client obtains the identity information of the target object based on the identity information input by the target object. This method occurs when the target client does not store the identity information of the target object, or when the identity information of the target object obtained according to method 1 is incorrect. Optionally, the identity information input box can be displayed before the bank selection interface is displayed, or after the bank selection interface is displayed, which is not limited in the embodiments of the present application. For example, Figure 5 As shown in (2), an identity information input box is displayed on the interface of the target client. When the target object enters identity information such as name, ID number, and communication number in the identity information input box and triggers the "OK" option, the target client obtains the identity information of the target object.

[0124] It should be noted that when only part of the target object's identity information is stored in the target client, method 1 can be used to obtain the stored part of the target object's identity information, and then method 2 can be used to obtain the remaining identity information of the target object. For example, assuming that the identity information required for binding a bank card is name, ID number, and communication number, and only the name and ID number of the target object are stored in the target client, then the name and ID number of the target object can be obtained according to method 1, and then the communication number input by the target object can be obtained according to method 2.

[0125] In step 204, the server of the target bank obtains the identity information of the target object based on the first interface.

[0126] The target bank's server has multiple interfaces, and different interfaces are used to receive different information sent by the target client. In the embodiment of the present application, the interface of the target bank's server that is used to receive the identity information of the target object sent by the target client is used as the first interface of the target bank's server.

[0127] 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 identification document number of the target object, the communication number of the target object, etc. Optionally, after obtaining the identity information of the target object, the server of the target bank can search whether there is bank card information that matches the identity information based on the obtained identity information of the target object. For example, when the identity information of the target object is the identification document number, the server of the target bank searches for bank card information that matches the identification document number in the relevant information of all stored bank cards. Bank card information refers to information related to each bank card itself, for example, the bank card number, the type of bank card, the validity period of the bank card, the security code of the bank card, etc. Optionally, the search results for whether there is bank card information that matches the identity information of the target object include the following two types:

[0128] Search result one: There is no bank card information that matches the target object's identity information. The reasons for this search result may be: the determined target bank is incorrect, and / or the obtained target object's identity information is incorrect. In other words, the target object's bank card does not exist in the target bank, and / or the target object's identity information is entered incorrectly. For example, the target object does not have a bank card from Bank of China, but selects Bank of China on the bank selection interface. In this case, the search result is that there is no bank card information that matches the target object's identity information; for another example, the target object's identity information 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 that matches the target object's identity information.

[0129] Under this search result, the server of the target bank can send a match failure response to the target client. After receiving the match failure response, the target client can redisplay the bank selection interface for the target object to reselect the target bank, and can also reacquire the identity information of the target object.

[0130] Search result 2: There is bank card information matching the identity information of the target object. Under this search result, step 205 is executed.

[0131] 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.

[0132] When there is bank card information matching the identity information of the target object, all bank card information matching the identity information of the target object is obtained 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 matching the identity information of the target object obtained may be bank card information corresponding to one or more bank cards. The bank card information corresponding to each bank card may include one or more information such as the bank card number, the type of bank card, the validity period of the bank card, the security code of the bank card, etc.

[0133] 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.

[0134] The bank card information matching the identity information of the target object includes information of one or more bank cards, and the information of each bank card includes one or more pieces of information. In the information of any bank card, it 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, such as the card type of the bank card, the validity period of the bank card, etc. In the process of the target bank's server sending the bank card information matching the identity information of the target object to the target client, all the acquired bank card information matching the identity information of the target object can be sent to the target client, or only one type of bank card information that can uniquely represent a certain bank card in all the bank card information can be sent to the target client. For example, only the card numbers of all bank cards in all the bank card information are sent to the target client, and each bank card number uniquely represents a bank card.

[0135] 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. The encrypted bank card information matching the identity information of the target object is then sent to the target client. The encryption method is not limited in the embodiment of the present application, for example, symmetric encryption, etc. This process can increase the security of the bank card information during transmission.

[0136] Optionally, after the target bank's server sends the bank card information matching the target object's identity information to the target client, the process also includes: the target bank's server sends a first verification code to the target object's terminal; after the target client receives the bank card information matching the target object's identity information, it displays a verification code input box; the target client obtains a second verification code entered by the target object in the verification code input box; the target client calls the second interface of the target bank's server and sends the second verification code to the target bank's server; the target bank's server obtains the second verification code returned by the target client based on the second interface. The target object's terminal refers to a terminal that can verify the target object's identity, such as a terminal where the target object's communication number is located. Here, the interface of the target bank's server interface for receiving the verification code sent by the target client is used as the second interface of the target bank's server.

[0137] 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 verification success response 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 verification failure response to the target client. Based on the verification failure response, the target client may display the verification code input box again, or may directly return to the home page of the target client, which is not limited in the embodiments of the present application.

[0138] In step 207, in response to receiving the bank card information that matches the identity information of the target object, the target client displays a bank card information interface that matches the identity information of the target object.

[0139] After receiving the bank card information that matches the identity information of the target object returned by the server of the target bank, the target client displays a bank card information interface that matches the identity information of the target object. In the displayed bank card information interface, the bank card information that matches the identity information of the target object is displayed. When the server of the target bank sends all the acquired bank card information 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 sends one type of bank card information that can uniquely represent a certain bank card among all the bank card information to the target client, only this type of bank card information is displayed on the bank card information interface. On the bank card information interface that matches 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 that matches 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, Figure 6As shown, the bank card information of bank card 1 is displayed in the first row of the list, the bank card information of bank card 2 is displayed in the second row of the list, the bank card information of bank card 3 is displayed in the third row of the list, and the bank card information of bank card 4 is displayed in the fourth row of the list.

[0140] Optionally, after receiving a successful verification response sent by the server of the target bank, the target client can display a bank card information interface matching the identity information of the target object in response to receiving bank card information matching the identity information of the target object and receiving a successful verification response.

[0141] Optionally, when the bank card information matched with the identity information of the target object received by the target client is encrypted bank card information, the target client first decrypts the encrypted bank card information and then displays the bank card information interface matched with the identity information of the target object.

[0142] Optionally, the target client displays a bank card information interface that matches the identity information of the target object in the following manner: the target client scrambles the reference position in the bank card information that matches the identity information of the target object, and then displays the scrambled bank card information interface that matches the identity information of the target object, so as to improve the security of the bank card information. Depending on the type of bank card information, the scrambling of the reference position in the bank card information is different. For example, for a bank card number, the reference position may refer to the position corresponding to the fourth to tenth digits of the card number; for a bank's security code, the reference position may refer to the position corresponding to the second digit of the security code, etc. The embodiment of the present application does not limit the scrambling method, for example, the digits at the reference position may be replaced by "*", etc.

[0143] In step 208, the target client determines the target bank card based on the operation on the bank card information interface, and binds the target client's account with the target bank card.

[0144] The operation on the bank card information interface may refer to the target object's selection operation on the target bank card information on the bank card information interface. 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 from 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, the bank card to be bound corresponding to the bank card information selected by the target object can be determined, that is, the target bank card. For example, Figure 6As shown, when the bank card information selected by the target object in the bank card information interface is card number 2, the target bank card can be determined to be bank card 2. After determining the target bank card, the target client binds the target client's account to the target bank card. This process does not require the target object to remember complex information such as the card number of the target bank card, thereby improving the target object's bank card binding experience and increasing the efficiency of bank card binding.

[0145] Optionally, the target client binds the target client's account with the target bank card, including: the target client calls the third interface of the target bank's server, sends a contract request to the target bank's server, and the contract request includes the target client's account and target bank card information; the target bank's server obtains the contract request based on the third interface, and then, based on the contract request, contracts the target client's account with the target bank card; in response to a successful contract, the target bank's server sends a successful contract instruction to the target client; in response to obtaining the successful contract instruction, the target client binds the target client's account with the target bank card. The third interface of the target bank's server refers to an interface for receiving the contract request sent by the target client.

[0146] Specifically, the binding process of the target client's account and the target bank card includes two steps: signing and binding. Among them, the signing is carried out in the server of the target bank; the binding is carried out in the target client. Signing refers to the signing of a contract between the target client's account and the target bank card, which is used to stipulate that when an online payment is made based on the application account, funds can be withdrawn from the target bank card account. Optionally, after the signing is successful, the target bank's server sends the target client a successful signing instruction including a signing agreement number, which is used to indicate that the signing is successful. After obtaining the successful signing instruction, the target client binds the target client's account to the target bank card. After the two steps of signing and binding, when an online payment is made based on the target client, funds can be withdrawn from the account of the bank card bound to the target client's account.

[0147] Related technology In the process of bank card binding, the interface of the target client displays the entrances of multiple banks, and based on the triggering instruction of the entrance of the target bank, jumps to the client of the target bank or the webpage of the target bank. In the interface of the client or webpage of the target bank, 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 target client's account with the target bank card in the target client. In this process, 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 is not friendly to users who have not registered bank accounts, the process of bank card binding is relatively complicated, and the efficiency of bank card binding is low. In addition, the security of bank card information is low in the jump process between the client and the client or the client and the webpage. In the embodiment of the present application, after the information of the target bank in the bank selection interface of the target client is triggered, the interface of the server of the target bank is called, the identity information of the target object is sent to the server of the target bank, and then the bank card information matching the identity information returned by the server of the target bank is displayed in the interface of the target client, and then the target bank is determined in the bank card information, and the account 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, jump between different clients, or jump between the client and the web page. The bank card binding process is relatively simple and efficient. In addition, during the process of the target client interacting with the bank's server by calling the bank's server interface, the bank card information is more secure.

[0148] In an embodiment of the present application, the target client calls the interface of the target bank's server, sends the target object's identity information to the target bank's server, determines the target bank card based on the bank card information returned by the target bank's server, and then binds the target client's account to the target bank card. The target client interacts with the target bank's server by calling the interface of the target bank's server, so that the entire bank card binding process can be completed in the target client alone, without installing other clients. The bank card binding process is relatively simple, and the efficiency of bank card binding is relatively high. In addition, the security of bank card information is relatively high during the interaction between the target client and the target bank's server.

When the user's identity is identified as a trusted identity, the processor 1201 authorizes the user to perform relevant sensitive operations, which include unlocking the screen, viewing encrypted information, downloading software, paying, and changing settings. The fingerprint sensor 1214 can be set on the front, back, or side of the terminal. When a physical button or manufacturer logo is set on the terminal, the fingerprint sensor 1214 can be integrated with the physical button or manufacturer logo.

[0213] The optical sensor 1215 is used to collect the ambient light intensity. In one embodiment, the processor 1201 can control the display brightness of the touch display screen 1205 according to the ambient light intensity collected by the optical sensor 1215. Specifically, when the ambient light intensity is high, the display brightness of the touch display screen 1205 is increased; when the ambient light intensity is low, the display brightness of the touch display screen 1205 is reduced. In another embodiment, the processor 1201 can also dynamically adjust the shooting parameters of the camera assembly 1206 according to the ambient light intensity collected by the optical sensor 1215.

[0214] The proximity sensor 1216, also known as a distance sensor, is usually arranged on the front panel of the terminal. The proximity sensor 1216 is used to collect the distance between the user and the front of the terminal. In one embodiment, when the proximity sensor 1216 detects that the distance between the user and the front of the terminal is gradually decreasing, the processor 1201 controls the touch display screen 1205 to switch from the screen-on state to the screen-off state; when the proximity sensor 1216 detects that the distance between the user and the front of the terminal is gradually increasing, the processor 1201 controls the touch display screen 1205 to switch from the screen-off state to the screen-on state.
