控制NFC标签的方法和受控NFC标签
摘要：
本发明提供一种控制NFC标签的方法和受控NFC标签，所述方法包括：产生用于使电子开关断开或导通的断开控制信号或导通控制信号；所述断开控制信号或导通控制信号施加在与NFC标签中的NFC天线线圈并联的电子开关上，从而使能或禁止所述NFC天线线圈中耦合的电磁能量向所述NFC标签中的NFC标签芯片传递。所述受控NFC标签包括：NFC标签主体、与NFC标签主体中的NFC天线线圈并联的电子开关、以及为该电子开关产生断开/导通控制信号的电子开关控制电路。有益效果是，使得对NFC标签芯片的读取是有条件的，从而避免一些不必要的操作，同时提高NFC标签芯片内的存储信息的安全性。
摘要（英）：

A method for controlling NFC tag and a controlled NFC tag, said method comprising: producing an on or off control signal causing an electronic switch to close or to open, the off or on control signal being exerted upon the electronic switch in parallel connection with the NFC antenna coil; by means of an enabling signal or a disabling signal emitted by the electronic switch, enabling or disabling transfer of electromagnetic energy coupled with the NFC antenna coil to the NFC tag chip. The controlled NFC tag comprises: an NFC tag body, an electronic switch in parallel connection with the NFC antenna coil, and an electronic switch control circuit producing on or off control signals for the electronic switch. The present invention allows information inside the NFC chip to be accessed according to certain conditions, thus avoiding unnecessary operations while enhancing the security of information stored in the NFC chip.
