Positioning system by using rfid

The present invention relates to a positioning system using the RFID, it is respectively provided to the cell area of ​​the set region-specific ID, and is installed on a plurality of RFID tags with the target for transmitting a location information of the area receiving the location information of the RFID tag receiving the current calculates its own location information, and the RF transmitter / receiver of the target, which transmits it, is installed on a moving object moving at the target location receives the position information of the RFID tag calculate the present own position information and the target RF transmitter / position information of a transmission target from the receiver and comparing their current location information includes a RF transmitter / receiver of a mobile positioning device calculates the direction and distance information to the target to be moved to the position of a target. Therefore, the present invention is to calculate the direction and distance information to the elderly, rescuers, etc. of the target to the RFID tag when used to track the location searching the position of the target and tracking device the target in the position tracking device to rapidly move the moving object to the target can.
