Abstract

NFC (Near Field Communication) technology is convenient for people's lives, but because of the abundant personal information contained in NFC cards, which can create a hidden danger for the leak of personal information. The existing NFC signal shielding cover is completely wrapped with a thin aluminum card, but this kind of wrapping will cause inconvenience to users. On the one hand, it covers cards and make cards invisible. On the other hand, when using, users need to remove the covers to let cards work normally. By HFSS simulation, this paper designed a new electromagnetic signal shielding transparent card cover, through changes of structural on copper ring to alter the strength of eddy current effect, realized the function of electromagnetic signal shielding controllable, and perfectly solved the existing technical problems.
