An NFC card with an indication function comprises an NFC coupling coil power supply, an NFC card circuit and a first light-emitting circuit. And the NFC coupling coil power supply is used for generating induction current to supply power to the NFC card circuit and the first light-emitting circuit. The NFC card circuit is used for data interaction with a reading device, and the first light-emittingcircuit is used for emitting light when the NFC coupling coil power supply supplies power. As the light-emitting unit is arranged on the surface of the NFC card, the reading state of the NFC card isdisplayed through the light-emitting state of the light-emitting unit, and then the indication function of the NFC card is achieved. 一种具有指示功能的NFC卡片，包括NFC耦合线圈电源、NFC卡片电路和第一发光电路。NFC耦合线圈电源用于产生感应电流为NFC卡片电路和所述第一发光电路提供电源。NFC卡片电路用于与读取设备进行数据交互,第一发光电路用于当NFC耦合线圈电源供电时发光。由于发光单元设置在NFC卡片的表面，通过发光单元的发光状态显示NFC卡片的读取状态，进而实现NFC卡片的指示功能。
