     DETAILED DESCRIPTION 
     The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, and not intended to limit the present application. It will be apparent to those skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating examples of the present application. 
     It should be noted that, relational terms such as first and second herein are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that any such relationship or sequence actually exists among these entities or operations. In addition, the terms “include”, “comprise” or any other variation thereof are intended to encompass non-exclusive inclusion, such that a process, method, article or device which includes a list of elements includes not only those elements, but also other elements which are not explicitly listed or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase “include” does not preclude the presence of additional identical elements in the process, method, article, or device that includes the element. 
     In some scenarios, a payment card bound to one electronic device needs to be migrated to another electronic device. For example, in a scenario that an electronic device is to be changed, it is necessary to migrate a payment card bound to an old electronic device to a new electronic device. In the related art, a device-changing card binding solution is provided, and the device-changing card binding solution includes the following steps that: 
     1) a user needs to unbind a payment card bound to a first electronic device from the first electronic device in advance; 
     2) the user turns on and activates a second electronic device, and logs in an account on the second electronic device; 
     3) the user opens a wallet application on the second electronic device, clicks “add a card”, then scans or adds a card, and selects a type of card to be added to the wallet application; 
     4) the user manually enters card detail information, and the user chooses to enter a card number and a short message verification code for the payment card, and in addition, under a condition that the payment card is a credit card, the user needs to manually enter a validity period and a CVN2 (Card Verification Number 2, security code) for verification; and 
     5) after the verification is passed, operations for device-changing card binding are completed. 
     With the device-changing card binding solution described above, a payment card bound to one electronic device may be migrated to another electronic device. However, when the user needs to bind a plurality of payment cards, the above steps 3-5 need to be repeated. In this case, the user needs to perform a plurality of operations to realize a payment card migration, resulting in that the payment card migration operations performed by the user are very cumbersome. 
     With respect to the above technical problem, the present application provides a method for migrating payment card. The following first illustrates a system for implementing the method for migrating payment card. 
       FIG.  1    is a schematic diagram of an embodiment of a system for implementing a method for migrating payment card provided by the present application. As shown in  FIG.  1   , the system for implementing the method for migrating payment card includes a first electronic device  102  (e.g., a new electronic device), a server  104 , a second electronic device  106  (e.g., an old electronic device), and a trusted service manager (TSM) system  108 . 
     After an account is logged in on the first electronic device  102  and the first electronic device  102  receives a payment card (e.g., a bank card, a shopping card, a membership card, or the like) migration operation, it displays at least one device identifier which is an identifier of an electronic device on which the above account had been logged in, for the user to perform selecting from at least one device identifier. Under a condition that the first electronic device  102  receives a first selecting operation for a target device identifier of the at least one device identifier, it sends the target device identifier to the server  104  to notify the server  104  that a payment card bound to the second electronic device  106  corresponding to the target device identifier needs to be migrated to the first electronic device  102 . 
     Under a condition that the server  104  receives the target device identifier, it migrates the payment card bound to the second electronic device  106  corresponding to the target device identifier to the first electronic device  102 . In particular, the server  104  sends a card binding request to the TSM system  108  to migrate the payment card bound to the second electronic device  106  to the first electronic device  102  by the TSM system  108 . 
     Therefore, a payment card migration is realized. Since a plurality of payment cards bound to the second electronic device  106  may be migrated to the first electronic device  102  simultaneously, the user does not need to perform unbinding and binding operations on the payment cards bound to the second electronic device  106  respectively, which simplifies the payment card migration operations performed by the user. 
     Based on the above system, the method for migrating payment card provided by the present application will be illustrated below.  FIG.  2    is a schematic flowchart of an embodiment of a method for migrating payment card provided by the present application. As shown in  FIG.  2   , the method for migrating payment card includes the follows. 
     In S 202 , a first electronic device receives a payment card migration operation after an account is logged in on the first electronic device. 
     In S 202 , as some examples, a payment application (e.g., a wallet application) may be installed on the first electronic device, and after an account is logged in on the payment application on the first electronic device, a payment card migration widget may be displayed on an interface of the payment application. The first electronic device receives a touch operation on the payment card migration widget by the user. The touch operation on the payment card migration widget by the user may be a click operation, a long-press operation, a double-click operation, or the like. 
     Further, the payment card migration operation is not limited to the touch operation on the payment card migration widget, but may also be a voice input operation. The payment card migration operation is not limited herein. 
     The method for migrating payment card further includes that: in S 204 , the first electronic device displays, in response to the payment card migration operation, at least one device identifier, and the at least one device identifier is an identifier of a target electronic device on which the account had been logged in. 
     In S 204 , as some examples, the first electronic device may send a request to a server to request to obtain the identifier(s) of the target electronic device(s) on which the above account had been logged in. Under a condition that the first electronic device receives the at least one device identifier sent by the server, it displays the at least one device identifier for the user to select, from the at least one device identifier, a second electronic device for which a payment card needs to be migrated to the first electronic device. 
     In an embodiment of the present application, the device identifier may be a model of the target electronic device on which the above account had been logged in, or the device identifier may be a user-defined name of the target electronic device on which the above account had been logged in. 
     The target electronic device may be an electronic device on which the above account had been logged in and a payment card is bound. In this way, the displayed at least one device identifier is an identifier of an electronic device bound with a payment card, and an electronic device which is not bound with a bank card is not to be displayed, thereby facilitating the user to select an identifier of an electronic device for which a migration is to be performed. 
     The method for migrating payment card further includes that: in S 206 , the first electronic device receives a first selecting operation for a target device identifier of the at least one device identifier. 
     In S 206 , the first electronic device may receive a touch operation on the target device identifier of the at least one device identifier by the user. In this case, the user selects the target device identifier, which is equivalent to that the user selects the second electronic device corresponding to the target device identifier and for which a payment card migration is to be performed. 
     The method for migrating payment card further includes that: in S 208 , the first electronic device sends, in response to the first selecting operation, the target device identifier to a server; and in S 210 , after the server receives the target device identifier, it migrates a payment card bound to the second electronic device to the first electronic device, and the second electronic device is an electronic device corresponding to the target device identifier of at least one target electronic device. 
     In S 210 , the server may send a card binding request to the TSM system. After TSM system receives the card binding request, it unbinds the bound payment card bound to the second electronic device from the second electronic device, and binds unbound the payment card to the first electronic device. 
     In particular, the card binding request may include a payment card code (e.g., mpan-id) bound to a security environment identifier (SEID) of the second electronic device. In this case, a card binding application channel type (applyChannelType) of the card binding request is “04 Channel”. After the TSM system receives the card binding request, it searches a corresponding field (span) based on the payment card code in the card binding request, and performs a card binding process based on the found field. During the performing of the card binding process, the TSM system sends an authentication request to a card issuing bank, to cause the card issuing bank to perform a verification. The card issuing bank system may verify at least one of a CVN2 (for a credit card, this item will not be verified), a validity period, a one-time password (OTP), and a password (for a credit card, this item will not be verified). After the verification by the issuing bank is completed, a mapping relationship of the payment card bound to the second electronic device is set to a linked state, and a response is sent to the TSM system. 
     With the embodiment of the present application, a plurality of payment cards bound to the second electronic device may be migrated to the first electronic device simultaneously, and the user does not need to perform unbinding and binding operations on the payment cards bound to the second electronic device respectively, which simplifies the payment card migration operations performed by the user. 
     In the related art, for security reasons, each time a payment card is bound to an electronic device, the user is required to manually input a short message verification code. Further, under a condition that the payment card is a credit card, the user is further required to manually input a validity period and a card verification number (CVN). In this case, in order to ensure security, a binding of bank card becomes more complicated, and the card binding operations are extremely cumbersome. 
     In order to solve the technical problem that the card binding operations are extremely cumbersome for ensuring security, in one or more embodiments of the present application, as shown in  FIG.  3   , after S 206 , the method for migrating payment card may further include the follows. 
     In S 212 , the first electronic device displays a verification code input interface. 
     In S 214 , under a condition that the server receives the target device identifier, it sends a first verification code to the second electronic device corresponding to the target device identifier, based on the target device identifier. 
     In S 216 , the first electronic device receives an input operation for inputting a second verification code on the verification code input interface. 
     In S 218 , the first electronic device sends, in response to the input operation, the second verification code to the server. 
     In this embodiment of the present application, S 210  may particularly include that: under a condition that the server verifies that the second verification code is the same as the first verification code, which indicates that the user of the second electronic device is a legitimate user, and the server migrates the payment card bound to the second electronic device to the first electronic device. 
     In an embodiment of the present application, before a payment card migration is performed, the server sends the first verification code to the second electronic device. If the first electronic device and the second electronic device belong to a same user or belong to two users with an associated relationship respectively, the user of the first electronic device may obtain the first verification code received by the second electronic device, and input the first verification code on the verification code input interface of the first electronic device. In this way, whether the user who performs the card migration operation is a legitimate user may be verified by using the verification code, thereby ensuring the security during a payment card migration process. 
     Further, if a plurality of payment cards bound to the second electronic device need to be migrated to the first electronic device, the user only needs to input the verification code once, and does not need to input the verification code every time a payment card is bound. Moreover, the user does not need to input information such as a validity period and a card confirmation code of the payment card, which may further simplify the payment card migration operations. 
     In one or more embodiments of the present application, the server sending the first verification code to the second electronic device corresponding to the target device identifier based on the target device identifier may include that: under a condition that the above account has been logged in on a payment application on the second electronic device, the server sends the first verification code to the payment application on which the account has been logged in. 
     In particular, if the server sends the first verification code to the payment application on which the above account has been logged in, the payment application on the second electronic device may receive the first verification code sent by the server through a network under a condition that the above account has been logged in on the payment application on the second electronic device and the payment application on the second electronic device is connected to the network. For example, under a condition that the second electronic device is connected to a wireless network (e.g., Wi-Fi, which is called Wireless-Fidelity), the second electronic device may receive the first verification code sent by the server through the wireless network. 
     In this way, by using a feature that a same account may be logged in on multiple electronic devices at a same time, when the account is logged in on the payment application on the first electronic device for performing a payment card migration process, the account may also be logged in on the payment application on the second electronic device, which enables that the second electronic device may receive the first verification code sent by the server. Thus, the user does no need to perform additional operations, and it is convenient for the user to migrate the payment card. 
     In one or more embodiments of the present application, the server sending the first verification code to the second electronic device corresponding to the target device identifier based on the target device identifier may include that: under a condition that a subscriber identity module (SIM) card has been installed on the second electronic device and a communication number corresponding to the SIM card is a predetermined communication number bound to the account, the server sends the first verification code to the communication number corresponding to the SIM card. 
     As some examples, the server may send a short message including the first verification code to the communication number corresponding to the SIM card, or the server may send voice information including the first verification code to the communication number corresponding to the SIM card. 
     In one or more embodiments of the present application, after the first electronic device responds to the first selecting operation, the method for migrating payment card may further include that: the first electronic device displays at least one payment card identifier which is an identifier of a payment card bound to the second electronic device; the first electronic device receives a second selecting operation for a target payment card identifier of the at least one payment card identifier; and the first electronic device sends, in response to the second selecting operation, the target payment card identifier to the server; and after the server receives the target payment card identifier, it migrate a target payment card bound to the second electronic device to the first electronic device, and the target payment card is a payment card corresponding to the target payment card identifier. 
     As some examples, after the first electronic device receives the first selecting operation for the target device identifier of the at least one device identifier, the first electronic device may display the at least one payment card identifier; or under a condition that the first electronic device receives information sent by the server which indicates that the second verification code is the same as the first verification code, the first electronic device displays the at least one payment card identifier. 
     In the embodiment of the present application, after the user selects the second electronic device for which a migration for the payment card bound thereto is to be performed, the identifier(s) of the payment card(s) bound to the second electronic device may be displayed on the first electronic device, for the user to select which one of the payment cards bound to the second electronic device is to be migrated. The user may choose to migrate all or some of the bank cards bound to the second electronic device based on his/her requirements. In this way, the user may select the payment card to be migrated on his/her own, to satisfy the user&#39;s usage needs. 
     In an embodiment of the present application, the payment card identifier may be a payment card number, a card-activating time, or a name of a card-activating company. 
     In some cases, it is possible that the identifiers of a plurality of electronic devices are the same as one another. For example, if the identifier of the electronic device is a model of the electronic device, the identifiers of two electronic devices with the same model are the same as each other. In this case, it is difficult for the user to distinguish the electronic devices with the same identifier, resulting in that the selected target device identifier may be not an identifier of an electronic device for which the migration is to be performed. 
     Before the user selects the target device identifier, in order to facilitate the user to distinguish respective electronic devices, in one or more embodiments of the present application, in response to the payment card migration operation and before receiving the first selecting operation for the target device identifier of the at least one device identifier, the method for migrating payment cards may further include: displaying information of a payment card bound to the target electronic device. 
     As some examples, the information of payment card bound to each target electronic device may be displayed, while the at least one device identifier is displayed; or under a condition that a touch input on a certain device identifier is received, the information of a payment card bound to the target electronic device corresponding to the device identifier may be displayed. 
     In an embodiment of the present application, the information of the payment card may include at least one of a name of a card-activating company of the payment card (e.g., a certain bank), an identifier of the card-activating company of the payment card, and a card-activating time. 
     In the embodiment of the present application, by displaying the information of the payment card bound to the target electronic device, it is convenient for the user to distinguish respective electronic devices, so as to facilitate the user to select the target device identifier from the at least one device identifier, and the selected target device identifier is an identifier of an electronic device for which the user intends to perform the migration. 
     In one or more embodiments of the present application, before the server migrates the payment card bound to the second electronic device to the first electronic device based on the target device identifier, the method for migrating payment card may further include: obtaining at least one piece of device information from pre-stored information, based on an user identification (UID) corresponding to the account, wherein the at least one piece of device information includes hardware information of at least one electronic device to which a payment card has been bound through the account. 
     The migrating the payment card bound to the second electronic device to the first electronic device based on the target device identifier may include: under a condition that information of the second electronic device matches any one of the at least one piece of device information, migrating the payment card bound to the second electronic device to the first electronic device based on the target device identifier. 
     In this way, whether the second electronic device has been bound with a payment card through the above account can be further verified. 
     The method for migrating payment card of any one of the embodiments provided by the present application may be applicable to a scenario that an electronic device is to be changed, and the payment card bound to an old electronic device is to be migrated to a new electronic device. It may also be applicable to a scenario that an electronic device is formatted. After formatting, the formatted electronic device is not bound with any payment card. By using the method for migrating payment card of any of the above embodiments, the payment card bound to the electronic device before formatting may be migrated to the formatted electronic device. 
     The method for migrating payment card according to the embodiments provided by the present application will be described with reference to the schematic diagrams of  FIG.  4    to  FIG.  8   , by taking a changing of an electronic device as an example below. 
     As shown in  FIG.  4   , after the account is logged in on the wallet application on the new electronic device, a “one-key migration” widget is displayed on the interface of the wallet application. Under a condition that the new electronic device receives a touch input on the “one-key migration” widget by the user, it displays an interface as shown in  FIG.  5   . At least one device identifier is displayed on the interface shown in  FIG.  5   . The at least one device identifier is a model of each electronic device on which the account had been logged in. 
     Under a condition that the new electronic device receives a first selecting operation for a target device identifier of the at least one device identifier by the user, the new electronic device displays a verification code input interface as shown in  FIG.  6   , and sends the target device identifier to the server, to cause the server sends the first verification code to the old electronic device based on the target device identifier. 
     The user may input the second verification code on the verification code input interface as shown in  FIG.  6    based on the first verification code received by the old electronic device. 
     Under a condition that the new electronic device receives the second verification code input by the user, it sends the second verification code to the server, to cause the server to verify whether the first verification code and the second verification code are the same as each other, and displays an interface as shown in  FIG.  7    on the new electronic device, which includes a card binding progress. 
     Under a condition that the server verifies that the first verification code and the second verification code are the same as each other, it migrates the payment card bound to the old electronic device to the new electronic device, and sends feedback information of successful migration to the new electronic device under a condition that the migration is succeeded. 
     Under a condition that the new electronic device receives the feedback information of successful migration, it displays a successful migration interface as shown in  FIG.  8   . 
     Based on the above method for migrating payment card, a method for migrating payment card provided by a first aspect of the present application and a method for migrating payment card provided by a second aspect of the present application will be described below. 
       FIG.  9    is a schematic flowchart of the method for migrating payment card provided by the first aspect of the present application. The method for migrating payment card provided by the first aspect is applicable to the first electronic device. As shown in  FIG.  9   , the method for migrating payment card includes the follows. 
     In S 302 , a payment card migration operation is received, after an account is logged in on the first electronic device. 
     In S 304 , in response to the payment card migration operation, at least one device identifier is displayed, and the at least one device identifier is an identifier of a target electronic device on which the account had been logged in. 
     In S 306 , a first selecting operation for a target device identifier of the at least one device identifier is received. 
     In S 308 , in response to the first selecting operation, the target device identifier is sent to a server, to cause the server to migrate a payment card bound to a second electronic device to the first electronic device, and the second electronic device is an electronic device corresponding to the target device identifier of at least one target electronic device. 
     In the embodiment of the present application, a plurality of payment cards bound to the second electronic device may be migrated to the first electronic device simultaneously, and the user does not need to perform unbinding and binding operations on the payment cards bound to the second electronic device respectively, which simplifies the payment card migration operations performed by the user. 
     In one or more embodiments of the present application, the target device identifier is to cause the server to send a first verification code to the second electronic device. After S 306 , the method for migrating payment card may further include: displaying a verification code input interface; receiving an input operation for inputting a second verification code on the verification code input interface; and sending, in response to the input operation, the second verification code to the server, to cause the server to migrate the payment card bound to the second electronic device to the first electronic device under a condition that the second verification code is verified to be same as the first verification code. 
     In an embodiment of the present application, before a payment card migration is performed, the server sends the first verification code to the second electronic device. If the first electronic device and the second electronic device belong to a same user or belong to two users with an associated relationship respectively, the user of the first electronic device may obtain the first verification code received by the second electronic device, and input the first verification code on the verification code input interface of the first electronic device. In this way, whether the user who performs the card migration operation is a legitimate user may be verified by using the verification code, thereby ensuring the security during a payment card migration process.
