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
[0006] At the same time, these three types of emulators all use dedicated emulation chips. The three types of emulation chips are different, and the design and production costs of emulation chips are very high. Three types of emulation chips are developed and three types of emulators are produced. The cost is very high for chip manufacturers, and there are too many varieties of emulators and emulation chips, which is not easy to manage

Embodiment Construction

[0017] As shown in the figure, a general 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 non-contact interface module 7 and a control module 5 . Among them, the emulation module 4 and the memory 3 are the same as those in common contact smart card emulators, non-contact smart card emulators and dual interface smart card emulators. The contact interface module 6 is the same as that in common contact smart card emulators and dual-interface smart card emulators. The non-contact interface module 7 is the same as that in common non-contact smart card emulators and dual-interface smart card emulators. 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 control whether the non-contact interface module 7 works through the control signal 14 .

[0018] The emulation chip 2 includes a processor...

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.

Description

technical field [0001] The invention relates to a smart card emulator, in particular to a general smart card emulator. Background technique [0002] At present, smart cards are mainly divided into three types: contact smart cards, contactless smart cards and dual-interface smart cards. Smart card emulators that provide users with debugging user programs are also divided into three types: contact smart card emulators, contactless smart card emulators and dual-interface smart card emulators. [0003] For the same smart card, the contact smart card, contactless smart card and dual-interface smart card chip of the same manufacturer basically have the same processor core, memory, coprocessor, etc. The difference is mainly in a small part of the external interface, and the dual interface The interface smart card is a combination of contact smart card and contactless smart card. The non-contact part of the contactless smart card and the dual interface smart card plus the processor...
