Virtual chip card system based on soft excitation electromagnetic near-field mutual inductance of mobile intelligent terminal

Abstract

The invention provides a virtual chip card system based on soft excitation electromagnetic near-field mutual inductance of a mobile intelligent terminal. When the mobile intelligent terminal runs a specific program, a current is generated in an internal circuit of the mobile intelligent terminal to excite soft excitation broadband electromagnetic signals different in frequency and amplitude. The mobile intelligent terminal realizes interaction with near-field information of a broadband electromagnetic card reader through information carried by the soft excitation broadband electromagnetic signals, and performs remote information interaction with an application data center through a wireless communication technology; and existing hardware of the mobile intelligent terminal does not need to be changed or added. The virtual chip card system has a multi-stage encryption method, supports a jointly signed check function and a quick loss report function, is secure and flexible, meets requirements of different applications on security and convenience, can be realized by replacing various chip cards such as a bank card, a door control card, a library card and the like, and can realize verification and use of the chip cards.

Description

Technical field [0001] The invention relates to electromagnetic near field induction, multi-level encryption and virtual chip card technology, in particular to a virtual chip card system based on soft excitation electromagnetic near field mutual inductance of a mobile intelligent terminal. Background technique [0002] With the development of information technology, more and more chip cards appear in our lives, such as bank cards, meal cards, urban transportation cards, access control cards, mall membership cards, library cards, etc. These cards may replace cash , Keys and other physical objects, or mark our identity and authority, make our life more convenient. However, various chip cards are issued by different institutions, usually using different reading devices and technologies, and different data interaction means, and the security encryption levels of various chip cards are also very different. For example, a bank card obtains data through a combination of near field comm...
