HARDWARE CALLING METHOD AND DEVICE FOR IC CARD APPLICATION, AND INTELLIGENT IC CARD

WIPO Patent Application WO/2023/142535

A1

A hardware calling method and device for an IC card application, and an intelligent IC card. The method comprises: acquiring a hardware calling instruction sent by an application program (210), wherein the hardware calling instruction is configured to indicate an application function to be realized; determining an application interface corresponding to the hardware calling instruction (220), wherein the application interface is encapsulated with an underlying application defined on the basis of preset service, the preset service is configured to provide a calling requirement for calling an underlying hardware by means of the application interface, and the underlying application corresponds to the underlying hardware; and calling the corresponding underlying hardware by means of the application interface, so as to realize the application function to be realized (230). Therefore, the independence between the application program and the underlying hardware is increased, and the reusability of the application program is improved; and the same application interface can support the calling of IC cards of different platforms, and therefore the universality of the application program and the underlying hardware is improved.
