Problems solved by technology
[0009] The technical problem to be solved by the present invention is: to overcome the defect that the existing non-contact IC card only needs to receive one incentive and is easily subjected to a relay attack to bring losses to the legal holder of the IC card, and to provide a method that needs to be activated after two incentives. In order to obtain complete data, effectively prevent relay attacks, and effectively protect the interests of legal IC card holders, the non-contact IC card with dual antennas and three-dimensional nesting

The invention relates to a double-antenna stereoscopically-nested non-contact IC (integrated circuit) card. The IC card comprises a plastic envelop, a first antenna, a first LC (inductance capacitance) resonance circuit, a first IC chip, a second antenna, a second LC resonance circuit and a second IC chip, wherein the first antenna, the first LC resonance circuit and the first IC chip are sequentially electrically connected; the second antenna, the second LC resonance circuit and the second IC chip are sequentially electrically connected; the first antenna and the second antenna are distributed in a mutually perpendicular nesting manner; the first antenna comprises a first antenna plane, and the second antenna comprises a second antenna plane; the first antenna plane and the second antenna plane are vertically intersected. According to the double-antenna stereoscopically-nested non-contact IC card, data are pre-stored in the first IC chip and the second IC chip, and complete data needs to be obtained by respectively stimulating the first IC chip and the second IC chip once; the complete data can be obtained after carrying out stimulating twice, so that the relay attack can be effectively prevented, and the benefit of a lawful holder of the IC card is effectively protected.
Description
technical field [0001] The present invention relates to an IC card (Integrated Circuit Card, integrated circuit card), in particular to a non-contact IC card requiring multi-directional triggering. Background technique [0002] Non-contact IC card, also known as radio frequency card, induction card, is composed of IC (integrated circuit, integrated circuit) chip and induction antenna, which are packaged in a standard plastic card, and the chip and antenna have no exposed parts. The card is close to the surface of the reader at a certain distance, and the data reading and writing operations are completed through the transmission of radio waves. [0003] In the existing non-contact IC cards, each card is equipped with an antenna, an L / C resonant circuit and an IC chip. When the antenna of the non-contact IC card receives the read-write stimulus, the card will resonate part of the stimulus with its own L / C to generate an instantaneous energy to supply the chip to work, and the...
