Abstract According to the influence of non-contact IC card on parameters of read-write equipment,the corresponding mathematic models are established.By simulating with a set of parameters,the influence degree of the card on parameters of read-write equipment can be quantitatively calculated.In order to realize the best energy transmission between the IC card and the read-write equipment,a matching network is needed between the source and load to get the impedance matching. Finally the calculation formula of RF matching network of the read-write equipment is deduced and verified.
