12. The non-transitory, computer-readable medium of claim 11 , wherein generating the payment DOI comprises:

generating the payment DOI based on local random factors.

13. The non-transitory, computer-readable medium of claim 12 , wherein generating the payment DOI based on the local random factors comprises:

obtaining a user identifier that is previously used to log in to the client application; and

generating the payment DOI based on the local random factors and the user identifier that is previously used to log in to the client application recently.

14. The non-transitory, computer-readable medium of claim 9 , wherein after the client application has started, the operations further comprise:

determining that a prompt message indicating that the payment has failed is received; and

in response, displaying a service page comprising the payment DOI, wherein the service page is not the start page.

15. The non-transitory, computer-readable medium of claim 9 , wherein the payment DOI is a two-dimensional code.

16. The non-transitory, computer-readable medium of claim 9 , where in the operations further comprise:

receiving, by a server, transaction information generated by the scanner after scanning the payment DOI, wherein the payment DOI comprises verification identifier information;

determining a corresponding verification method for the transaction information based on the verification identifier information in the payment DOI;

performing a verification for the transaction information using the corresponding verification method; and

determining, based on a verification result, whether to complete the payment.

17. A computer-implemented system, comprising:

one or more computers; and

one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform operations comprising:

determining, when a client application starts in a current running process, that a startup mode is a cold start; and

in response to determining that the startup mode is the cold start, displaying a start page comprising a payment digital object unique identifier (DOI) to be scanned by a scanner to make a payment by scanning the payment DOI,

wherein, before determining that the startup mode is the cold start, pre-generating, by the client application in a previous running process, the start page comprising the payment DOI, and
