Description

Card returning method and system based on super SIM card Technical Field The invention relates to the technical field of digital management, in particular to a card returning method and system based on a super SIM card. Background At present, the super SIM (Subscriber Identity Module) card is widely applied to the bearing of traffic cards, access cards, digital RMB and other businesses in the fields of mobile payment and digital asset management. In a mobile payment scene, a bank card certificate or a payment token can be safely hosted in a security element arranged in a super SIM, transaction signature and two-factor authentication are carried out by a private key which cannot be derived in the card, and token issuing, updating and revocation are completed through a controlled remote reprogrammable channel, so that the risk of cloning and remote theft is remarkably reduced. The existing super SIM card-based card withdrawal method is mainly characterized in that a strict sequence triggering type flow is adopted in most of the realization, and due to the lack of a parallel and compensation mechanism, the whole card withdrawal flow is interrupted due to failure of any intermediate link when a mobile network fluctuates or an external system fails in a short time, so that a user has to repeatedly initiate operation, experience is poor and service availability is low. Disclosure of Invention The invention provides a card returning method and system based on a super SIM card, which are used for improving the reliability and consistency of card returning based on the super SIM card. In order to solve the technical problems, the invention provides a card returning method based on a super SIM card, which comprises the following steps: responding to a card withdrawal instruction, generating a global flow identifier based on the card withdrawal instruction, and creating a state record based on the global flow identifier; Initializing the state record, and executing card-returning operation based on the global flow identifier and the state record, wherein the card-returning operation comprises a plurality of discretized sub-flows; And in each card-ejecting operation, acquiring the execution state of each sub-process in real time, and based on the execution state and updating the state record, obtaining a first state record of the current card-ejecting operation, if the state mark of the first state record does not meet the preset condition, taking the first state record as the state record of the next card-ejecting operation, and based on a preset retry strategy, executing the next card-ejecting operation until the state mark of the first state record of any card-ejecting operation meets the preset condition, and completing the card-ejecting operation. The invention introduces the global flow mark at the initial stage of the card withdrawal flow, so that each card withdrawal service has unique and traceable identity mark in the system, thereby avoiding flow confusion and state conflict caused by concurrent or repeated card withdrawal requests, and simultaneously, realizes unified management and state bearing of the whole life cycle of the card withdrawal flow by creating the state record bound with the global flow mark, provides reliable data basis for subsequent flow driving, abnormal positioning and audit tracing, and remarkably improves the controllability and consistency of the system in a distributed environment. The method and the device divide the original linear and strongly-dependent card withdrawal business into a plurality of sub-processes with definite semantics and relatively independent, and perform unified initialization and arrangement through state records, so that card withdrawal operation is converted into state drive from process drive, the coupling degree between the sub-processes is reduced, independent evolution and maintenance of different sub-processes are facilitated, structural basis is provided for subsequent refined control, step recovery and abnormal isolation, the expandability and system robustness of the whole card withdrawal process are improved, furthermore, the execution state of each sub-process is collected and persisted in real time in the card withdrawal execution process, so that the current stage of the card withdrawal process and the completion condition of each sub-process can be accurately mastered, the process state loss caused by process interruption or service restarting is avoided, and meanwhile, the formed first state record is used as objective reflection of one-time complete execution result, and provides clear basis for whether the follow-up execution is continued or not and whether retry is needed, thereby enhancing the transparency and observability of the process execution. Finally, the state record formed by the previous execution is directly used as the input of the next card withdrawal operation, so that the continuous operation and the accurate retry of the br
