An RFID tag and a program recording medium are provided to supply power to an RFID chip when mass data is transceived, long distance communication is needed, or security process is needed by efficiently managing power distribution between a sensor and an RFID tag in a sensor-embedded RFID tag. A sensor processor(115) manages data extracted and/or generated through the sensor. A battery(125) supplies power to the RFID chip(100) and the sensor. A power manager(120) manages the power supplied to the RFID chip and the sensor by controlling a power supply switch between the RFID chip and the battery, and controlling the power supply switch between the sensor and the battery. The power manager receives a sensor measurement time command from the RFID chip and stores operation period of the sensor corresponding to the sensor measurement time command to a memory. The power manager turns on the power switch between the sensor and the battery by checking a sensor operation period from the memory. |
