摘要： A battery-powered RFID tag capable of reducing power consumption and a method of waking up the RFID tag are provided. The battery-powered RFID tag has an activated mode where a general command is detected by decoding a signal received from an RFID tag reader and the general command is executed and a standby mode where the general command is not detected. If a voltage of a continuous wave detected from the signal is equal to or higher than a predetermined voltage or if a wake-up command is detected from the signal, the state of the RFID tag is changed from the standby mode to the activated mode. In addition, the RFID tag is driven by a higher one between the voltage of the continuous wave and a voltage of a built-in battery.
