High-concurrency universal payment method

The invention provides a high-concurrency universal payment method including the steps that when a system entry server receives a synchronization request, a structure TransInfo object used for storing the synchronization request is generated, a sequence number is distributed to the TransInfo object, and then the sequence number is stored in the TransInfo object; the TransInfo object is placed into a TransInfo processing queue; the sequence number of the TransInfo object serves as a parameter to call a tpforward system entry service, accordingly the TransInfo object enters a service request queue and waits for processing, and the sequence number of the TransInfo object is stored in the parameter of tpforward. By means of the method, high concurrency is achieved by simultaneously processing multiple transaction requests, and high expansibility is achieved through interaction of the method and an external transaction system in a unified link management mode.
