摘要: Provided are a method and apparatus for stopping power supply to a radio frequency identification (RFID) system. The apparatus includes: a power supplier supplying power to a high RFID tag; an input unit rectifying and boosting an input predetermined frequency band signal and outputting a direct-current (DC) voltage signal; a wake-up determiner comparing a voltage of the DC voltage signal output from the input unit with a predetermined reference voltage and outputting a HIGH signal or a LOW signal; and a switch stopping power supply to the high RFID tag if the wake-up determiner outputs the LOW signal.
