The signal generation unit generates a calling signal including the tag identifier information corresponding to an object in order to identify the object wanting to recognize the location, and transmits to the signal/power transmitter. The signal/power transmitter processes the signal in order to wirelessly transmit a power signal and the calling signal. The magnetic resonance unit is comprised of a magnetism resonator having the same resonant frequency with a wireless frequency identification tag(20) and provides the power signal and the calling signal received from the signal/power transmitter to the wireless frequency identification tag. The signal receiving unit obtains the tag identifier information or the position information about the tag called from the received signal which is signal-processed. The position information processor tracks the position of the object in which the wireless frequency identification tag is adhered based on the tag identifier information and position information.
