Abstract
A radio frequency identification (RFID) tag based object position tracking apparatus and method are provided. The apparatus includes a position recognizer including at least one radio frequency identification unit for reading information data on an object through a sensor; and a path analyzing and processing unit for allocating each unique coordinates to the radio frequency identification units based on a relative position in a space where a position recognizer is disposed and recognizing the position of the object and analyzing the path based on the object information data received by the sensor in the radio frequency identification unit corresponding to the unique coordinate. Thus, it is possible to track the path of an object with a low density of RFID tags.
