Problems solved by technology

[0005] For users to develop user programs for these three types of smart cards, there must be three types of emulators: contact smart card emulator, contactless smart card emulator and dual-interface smart card emulator, as a dedicated emulator with a small amount of usage. The price of such emulators is generally relatively high, and purchasing three emulators will objectively increase the user's development cost

Abstract

This invention discloses a kind of general intellect card simulator which includes a simulate slug, a simulate module, a storage card, and a contact interface module, a non-contact interface module and a control module. The simulate slug includes a processor kernel, a secondary processor, a memory interface unit, a contact interface unit and a non-contact interface unit; the control module said above can be inverted to the needed contact intellect card simulator, the non-contact intellect card simulator or the double face intellect card simulator by controlling the contact interface module, the non-contact interface module, the contact interface unit and the non-contact interface unit. This invention has the simple settings and can make one simulator support the contact intellect card, the non-contact intellect card and the double face intellect card at the same time. It is not only benefit to reduce the development cost for the simulate tool and manage it easily but also benefit to reduce the development cost of the program for users.

Example Embodiment

[0017] As shown in the figure, a universal smart card emulator 1 of the present invention includes an emulation chip 2, an emulation module 4, a memory 3, a contact interface module 6, a contactless interface module 7 and a control module 5. Among them, the simulation module 4 and the memory 3 are the same as those in a common contact smart card simulator, a contactless smart card simulator, and a dual interface smart card simulator. The contact interface module 6 is the same as the ordinary contact smart card emulator and dual interface smart card emulator. The contactless interface module 7 is the same as the ordinary contactless smart card emulator and dual interface smart card emulator. The user can use the control module 5 of the emulator 1 to control whether the contact interface module 6 works through the control signal 13 and whether the non-contact interface module 7 works through the control signal 14.
[0018] The simulation chip 2 includes a processor core 11, a coprocessor 12, a memory interface unit 10, a contact interface unit 8, and a contactless interface unit 9. Among them, the processor core 11, the coprocessor 12, and the memory interface unit 10 are the same as those in the ordinary contact smart card emulation chip, the contactless smart card emulation chip, and the dual interface smart card emulation chip. The contact interface unit 8 is the same as the ordinary contact smart card emulation chip and the dual interface smart card emulation chip. The contactless interface unit 9 is the same as that of a normal contactless smart card emulation chip and a dual-interface smart card emulation chip. The user can use the control module 5 of the emulator 1 to control whether the contact interface unit 8 in the simulation chip 2 works through the control signal 15 and whether the contactless interface unit 9 in the simulation chip 2 works through the control signal 16.
[0019] Using the universal smart card emulator 1, when a contact smart card needs to be simulated, the user uses the control module 5 of the emulator 1 to start the contact interface unit 8 of the emulation chip 2 and the contact interface of the emulator 1 through the control signal 15 and the control signal 13 Module 6 prohibits the contactless interface unit 9 of the emulation chip 2 and the contactless interface module 7 of the emulator 1 through the control signal 16 and the control signal 14, and a contact smart card emulator can be obtained. When it is necessary to simulate a contactless smart card, the user uses the control module 5 of the emulator 1 to activate the contactless interface unit 9 of the emulation chip 2 and the contactless interface module 7 of the emulator 1 through the control signal 16 and the control signal 14 The control signal 15 and the control signal 13 prohibit the contact interface unit 8 of the emulation chip 2 and the contact interface module 6 of the emulator 1, and a contactless smart card emulator can be obtained. When a dual-interface smart card needs to be simulated, the user uses the control module 5 of the emulator 1 to start the non-contact interface unit 9 and the contact interface unit 8 of the simulation chip 2 through the control signal 15 and the control signal 16, and through the control signal 13 and control signal 14 Start the non-contact interface module 7 and the contact interface module 6 of the emulator 1, and a dual interface smart card emulator can be obtained.
