Lo Tzu-Li Yang and Kuo-Hui Yeh National Taiwan University of Science and Technology Taiwan . 1. Introduction With extended data storage space and advanced wireless transmission capability Radio Frequency IDentification RFID is rapidly deployed to replace barcode position in our daily lives and considered as the next generation identification technology in ubiquitous communication environment. The most important key factor of RFID technology is to enable systems with the ability to automatically identify labeled objects without the constraint of line of sight. RFID technology is a well known AIDC Automatic Identification and Data Capture technology to provide the benefits including contactless read long transmission range and transaction time saving Garfinkel Rosenberg 2005 . Most of innovative applications designed for RFID system can be divided into following classes such as asset management tracking authenticity verification matching process control access control automated payment and supply chain management Karygiannis et al. 2007 . In spite that the adoption of RFID technology becomes popular in a board range of applications the cost of a RFID tag is still too expensive to be fully adopted by logistic and retailer industries. Even though from the logistic and retailer industries point of view to label RFID tags on all sale items is still cost-prohibitive under the current price of a passive RFID tag. Nevertheless the convenience of RFID technology still has a great attraction for inventory management. For example in 2005 Wal-Mart which is the biggest retailer in America declared a new policy to force its top 500 suppliers to adopt RFID technology for inventory management otherwise Wal-Mart will deny new transaction contracts from those who do not comply this new policy. Because of this policy all top 500 suppliers start to apply RFID tags onto their merchandises by spending and .
