  • Method for implementing middleware based on EMV and terminal device
    Patent number: 12039518
    Abstract: The present application provides a method for implementing a middleware based on EMV, a terminal device, and a computer-readable storage medium. The method includes: establishing a middleware based on EMV L2, wherein the middleware provides a first interface for an upper-layer application of the terminal device to call; after the middleware receives a calling request for the first interface sent by the upper-layer application according to detected information of a IC card, calling an interface of an Entry library according to the calling request to obtain a return result of the Entry library, wherein the return result of the Entry library comprises an application identifier of the IC card; and determining an EMV L2 library matching the IC card based on the application identifier, and calling an interface of the EMV L2 library matching the IC card, to complete a contactless process with the IC card.
