Abstract: A method for data processing include: when payment is triggered by an e-commerce application program, calling a first SDK to obtain a first host program list from a network-wide payment platform, where the first host program list includes host program identifiers of at least part of host programs supported by the network-wide payment platform; when a target host program is determined from the first host program list by calling the first SDK, calling the target host program; and calling, by means of the target host program, a second SDK to interact with the network-wide payment platform, so that the network-wide payment platform interacts with the host program platform to complete payment by a target card, the target card being a resource card bound to the target host program.

Abstract: A method for compatibility of an SDK with an access application includes transmitting to a management and control center bridge configuration information of an access application, the bridge configuration information representing configuration of an application function module of the access application; receiving a specific bridge issued by the management and control center and matched with the bridge configuration information, the specific bridge including a specific compatibility policy and SDK function modules, and the specific compatibility policy being used for carrying out specific processing on service parameters required by the application function module, so as to make the service parameters compatible with service parameters required by an SDK functional component in an SDK having a function corresponding to the application function module; mounting the specific bridge in the SDK; and when the access application runs the application function module, calling the corresponding SDK functional component

Abstract: A payment includes: in response to a received payment request message, sending a security verification request message to a security control system, the security verification request message is used to instruct the security control system to perform security verification according to security verification information; receiving security verification result information sent by the security control system; when the security verification result information indicates that the security verification is passed, sending a first notification message to the SDK, the first notification message instructs the SDK to notify the host program to display a user verification page to prompt the user to enter the first user verification input information, the first user verification input information is used for the host program server to perform user verification to obtain user verification result information; when the user verification result information indicates that the user verification is passed, initiating a payment requ
