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

Abstract

The invention provides a virtual chip card system based on the near-field mutual induction of the soft excitation electromagnetic of the mobile intelligent terminal. When the mobile smart terminal runs a specific program, current is generated in its internal circuit, which excites soft excitation broadband electromagnetic signals of different frequencies and amplitudes. The mobile intelligent terminal uses soft excitation broadband electromagnetic signals to carry information to realize the near-field information interaction with the broadband electromagnetic card reader, and at the same time conducts remote information interaction with the application data center through wireless communication technology, without changing or adding the existing hardware of the mobile intelligent terminal. The system has a multi-level encryption method, and supports the joint audit function and the rapid loss report function. It is safe and flexible, and can meet the security and convenience requirements of different applications. It can replace various chip cards such as bank cards, access control cards, and library cards to realize virtual The chip card system realizes the verification and use of the chip card mentioned above.

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 induction of mobile smart terminals. 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, shopping mall membership cards, library cards, etc. These cards may replace cash Objects such as keys, keys, etc., or mark our certain identity authority, make our life more convenient. However, various chip cards are issued by different organizations, usually use different reading devices and technologies, and have different data exchange methods, and the security encryption levels of various chip cards are also very different. For example, a bank card obtains data through a combination of nea...
