Abstract
RFID tags assign computer-readable identification codes to articles and data is obtained from each RFID tag at points along which an article moves. Each RFID tag is separable into an article identification tag section, including an article identification code and a transmitter transmitting same, and an article information management tag section, including an obtaining device continuously obtaining article-related information of an article to which an RFID tag is assigned, a receiving device receiving the article identification code from the article identification tag section, a detecting device detecting the combination status of the article information and the article identification tag section, and a storage device storing the article identification code and the article-related information when the article information and article identification tag sections are in contact with each other.
