Radio frequency identification (RFID) systems are emerging as the primary object identification mechanism, especially in supply chain management. However, RFID naturally generates a large amount of duplicate readings. Removing these duplicates from the RFID data stream is paramount as it does not contribute new information to the system and wastes system resources. Existing approaches to deal w...

According to professional journals, Internet information services and consultants, RFID (Radio Frequency Identification) seems to be “the new technology hype” which “will revolutionise business performance across supply chains” (Accenture). While low-frequency RFID has been used in some areas in the industrial world for more than a decade (source), the recent decision by Wal-Mart and the U.S. D...

radio generation and transmission of radio signals by Ernst F. W. Alexanderson in 1906 signalled the beginning of modern radio communication and, subsequently, radio frequency identification (RFID). RFID is the convergence of radio broadcast technology and radar, although many of its early developments are not widely known due to the military significance of this technology. Most documented his...

Radio Frequency Identification (RFID) systems have provided promising solutions to effective identification of a large number of tagged objects. However, RFID systems suffer from unauthorized tag reading and potential eavesdropping, which becomes a challenging issue because of the shared radio medium and limited size and cost considerations in RFID. In this paper, based on a Linear Congruential...

Successful object identification is the primary objective of Radio Frequency Identification (RFID) technology. Yet, a recent major study by Wal-Mart has shown that object detection probability can be as low as 66%. We propose the tagging of objects with multiple tags to address the fundamental issue of object detectability. We show that this strategy dramatically improves the efficacy of RFID s...

─ In this paper we provide the basis of using radio frequency identification (RFID) tags for advertisement. Two RFID tags that apply to the 866 MHz and 915 MHz operating frequencies, respectively, were designed based on the logos of two universities participating in this project. Several fabrication methods were used to build the RFID tags on different substrates. The experimental results exhib...
