Enhanced tag identification method for efficient RFID system

Abstract

Recently, many studies are made about RFID system which is spread in many areas such as logistics and distribution, medical treatment. For it is necessary to identify many objects during short time, RFID system needs the method to minimize the tag collision and to shorten the processing time for tag identification. Therefore, this paper proposes the method to identify the tag by using two readers, instead of conditions of only one reader which is generally used for the improvement of tag identification speed in RFID system. The proposed method minimizes tag collision and improves tag identification speed by identifying each of limited tag ID through the use of two readers. © 2011 Springer-Verlag.
