Abstract: A service voucher processing method, device, and system, and a storage medium are disclosed. The method includes: obtaining information about a candidate service, and loading a virtual identifier of the candidate service in a graphical interface; initiating, if a target service reserved by the reservation instruction is detected, a reservation request; obtaining a service voucher corresponding to the target service based on permission corresponding to the target service, and activating the service voucher when an instruction for using the target service is detected; performing authentication on the permission, a verification request carrying permission information, and a serial communication method being used for the verification request; and providing the permission when the authentication passes, determining that the target service is used, and cancelling the permission.
