摘要： A passive tag including a volatile memory is provided. The passive tag includes: a sensing unit which senses or measures information about environmental surroundings of the tag; a volatile memory; a non-volatile memory; and a control unit which firstly stores resultant data sensed or measured by the sensing unit in the volatile memory and then moves the data stored in the volatile memory to the non-volatile memory according to pre-set conditions. Therefore, the life of the tag is prolonged and stability of important data can be secured.

摘要： According to the present invention, the apparatus receives a radio frequency (RF) signal transmitted from the Radio Frequency Identification (RFID) reader, measures the strength of the received RF signal, and controls the power supplied from the power supply unit included in the tag or the power excited by the RF signal to be supplied to the tag according to whether the power excited by the received RF signal exceeds a level necessary to operate the tag based on the measured strength of the RF signal. Thus, efficiency of power consumption of the tag and the RFID transmission/reception system can be maximized and the amount of data is reduced to the extent that the set of commands is not needed, thereby simplifying a data process.

摘要： Provided are a radio frequency identification (RFID) tag and a wake-up method thereof. The RFID tag includes: a power source that supplies a driving voltage; a continuous wave detector that receives the driving voltage from the power supply so as to detect a continuous wave in a signal received from an RFID tag reader; a command detector that selectively receives the driving voltage and detects a command in the signal; and a controller that executes the command detected by the command detector by supplying the driving voltage to the command detector if the continuous wave is detected, and stops the driving voltage from being supplied to the command detector if no command is received from the command detector for a predetermined time period.
