PURPOSE: A materials management method is provided to utilize an RFID (Radio Frequency Identification) based system which is not affected by a surrounding environment and space, thereby sharing accurate data on a list and a location of released materials. CONSTITUTION: A fixed RFID tag (10) is installed on an external bottom surface. A materials RFID tag (20) is attached to materials released around the fixed RFID tag. After reading information is transmitted from the fixed RFID tag and the materials RFID tag through a portable wireless terminal (30), the information and the location of released materials are stored by being transmitted to a materials managing unit (70). If the information and the location of the released materials are requested through the portable wireless terminal, the materials managing unit displays requested information based on location information of the fixed RFID tag through the portable wireless terminal.
