Embodiment Construction

[0017] figure 1 It is a flowchart of Embodiment 1 of the method for accessing a smart card by an application program of the present invention, such as figure 1 As shown, the method for an application program to access a smart card provided in this embodiment is especially applicable to a scenario where a third-party Android application program needs to access a smart card. The smart card is specifically carried in terminal devices with an Android system such as smart phones, palmtop computers, and tablet computers. The smart card includes various application program blocks (applets) placed by operators, such as storage, computing, etc., and Android applications During the development of the program, it is necessary to access these Applets in the smart card to complete corresponding operations. In order to realize the access to the Applet in the smart card, it is necessary to use the standard APDU command compatible with the smart card to complete the interaction with the smar...

Abstract

The invention provides a method and a device for accessing an intelligent card by an application program. The method comprises the following steps: receiving, by an agent program, an operation instruction transmitted by the application program by calling an open API (Application Programming Interface) function, wherein the open API function is encapsulated by a standard APDU (Application Protocol Data Unit) instruction corresponding to the operation instruction; adding operation information in the operation instruction into the standard APDU instruction corresponding to the open API function by the agent program and transmitting the standard APDU instruction to the intelligent card to operate the intelligent card according to the standard APDU instruction. The open API function provided by the agent program is only required by the application program to transmit the operation instruction of the application program to the agent program, and the access of the intelligent card by the application program is automatically finished by the agent program, so that the requirements on abilities of developers and the development difficulty of the application program are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and a device for an application program to access a smart card. Background technique [0002] With the enhancement of smart card processing capabilities, the expansion of storage space and the development of mobile value-added services, smart cards are no longer only used as access authentication modules for mobile communication networks, but can provide relevant storage for applications such as mobile payment and short-distance communication. , authentication and other functions. [0003] At present, many smart phones use the Android system platform. When third-party Android application developers develop new value-added service applications or upgrade and improve existing value-added services, they need to interact with the smart card to call the smart card. The application block (applet) related to the value-added service application completes the c...
