Summary:The utility model discloses an NFC card, which comprises a card body and an NFC card circuit, and is characterized in that the NFC card circuit is arranged on the card body and comprises a COB packaging chip and a coil antenna. The card body comprises an anti-metal shielding layer and an antenna substrate layer. Wherein the coil antenna is flatly laid on the antenna substrate layer, the COB packaging chip is connected with the coil antenna in an attached mode, and the anti-metal shielding layer is arranged on the coil antenna in an attached mode. As the material of the anti-metal shielding layer comprises the anti-metal shielding material, the anti-metal shielding layer is used for enhancing the receiving magnetic field intensity of the NFC card and increasing the induction distance of theNFC card, and the card reading success rate when the NFC card is attached to the metal surface is further improved. The antenna substrate layer is made of the FPC flexible circuit board, has the characteristics of the FPC fl
