  • This paper described a metal mount RFID tag that works reliably on metallic surface. The proposed method is to use commercial RFID tags, Styrofoam103.7 material is attached on back side of RFID tag. Styrofoam103.7 material which has 2.5 mm thickness and 1.03 relative permittivity, was attached on back side of RFID tag. In order to verify the performance of proposed method, we evaluated the experiment on the supply chain system of electric transformers using RFID. The experimental results on supply chain of electric transformers show that the proposed tags can communicate with readers from a distance of 2 m. The results of recognition rates are comparable to commercial metallic mountable tags.

  • The emergence of RFID markets and development of various RFID-embedded mobile devices has brought fundamental changes to our lives. As the availability of RFID readers and tags that are implanted in smart phones and table PCs increases, information on RFID-affixed objects can be tracked wirelessly and this had open possibilities for B2B businesses to be run like B2C businesses. However, given the popularity of the RFID markets, there is limited research in this area. This paper serves to develop an extended technology acceptance model by Mobile RFID characteristics (perceived cost, security, instant connectivity, context awareness, and result demonstrability) examines the determinant factors that cause the acceptance of mobile RFID. To do so, the study conducted a survey targeting smart phone users and used the PLS path modeling, one of the structural equation models to verify the significance of research hypothesis. As a result, perceived cost, instant connectivity, context awareness, and result demonstrability turned out to have a real effect on intention to use mobile RFID by means of perceived usefulness and perceived ease of use. Security turned out to have a partial effect on intention to use mobile RFID by means of perceived usefulness or perceived ease of Use.

  • In this paper, we analyze the active RFID systems ISO/IEC 18000-7 and ISO/IEC 18000-4. In order to improve the coverage in sensor networks, which consist active RFID tag, we propose RFID multi-hop relay system using active RFID relay tag. To compare the performance between the existing ISO/IEC 18000-7 system and the proposed RFID multi-hop relay system, we introduce new system efficiency measure and sensitivity-based measure of achieved coverage. Also, we analyze the performance of the proposed system and compare it with that of the existing system through MCL (Minimum Coupling Loss) analysis and SLS (System Level Simulation) analysis.

  • One of the key issues in implementing RFID systems is to design anti-collision protocols for identifying all the tags in the interrogation zone of a RFID reader with the minimum identification delay. In this paper, Furthermore, in designing such protocols, the limited resources in tags and readers in terms of memory and computing capability should be fully taken into consideration. we first investigate two typical RFID anti-collision algorithms, namely RFID Gen2 Q algorithm (accepted as the worldwide standard in industrial domain) and FAFQ algorithm including their drawbacks and propose a new RFID anti-collision algorithm, which can improve the performance of RFID systems in terms of tag identification time considerably. Further, we compared performance of the proposed algorithm with Q algorithm and FAFQ algorithm through computer simulation.

  • Textile industry of Domestic has been descended in the sector of design, brand, recognition comparing with developed countries. And products of middle and low price do not have competitiveness against developing countries. In addition, textile industry market is changing from the provider market-oriented to consumer-driven market. RFID(Radio Frequency Identification) is the core technology to correspond in the these environmental change. RFID is a technology that is used to communicate with identified objects using radio waves, so that the objects can be recognized, tracked and traced. In this study, we reviewed characteristic and present condition of domestic textile industry and newest technology aspect of RFID. Also, we suggested application plan of RFID technology in textile industry through the analyzing RFID application case of domestic and outside the country textile industry.

  • Recently, RFID technology can successfully be used to reduce medical errors. This technology can aid in the accurate matching of patients with their medications and treatments. The enthusiasm for using RFID technology in medical settings has been tempered by privacy concerns. In this paper, we propose a secure and efficient RFID authentication system to not only authenticate patients' authenticity but also protect patients' personal medical informations. The proposed system consists of RFID-based patient authentication protocol and database security protocol. As a result, since the proposed RFID authentication system provides strong security and efficiency, it can be used practically for patient authentication and personal medical information protection on the high technology medical environments such as u-Hospital and u-Healthcare.

  • The paper introduces the RFID location based Tree Management System (TMS) using UHF RFID tag and GPS. The bolt shape tag has been developed since the wood material has high dielectric constant. Since the characteristics and impedance of tag antenna can be changed by the material next to the tag, the plastic bolt shape tag antenna has to be carefully designed with consideration of the high dielectric constant of the wood material. The RFID TMS system has been utilized with the bolt shape tag antenna and GPS. The TMS system uses and links Google map to locate the location of the trees. Therefore, this system allow us to manage the trees economically and efficiently.

  • KISA announced KKR code system observing the international standard, ISO/IEC 15459, in order to activate the domestic RFID industry and improve mutual operation among RFID services. In this paper, we propose the way on code conversion based on ontology methods so as to effectively convert various types of RFID KKR code data collected from RFID reader into URN code in the middleware based on the ALE standard spec of EPC global. The results of experiment show that various types of RFID KKR code data could be converted into URN codes successfully. This means that even though new types of KKR code are added, it can be extended easily by adding ontology information without rebuilding the middleware.

  • The RFID market seems to grow mostly in the logistics and distribution areas. The areas and small sized work places requires multi-steps based system. In the environment, the performance of RFID READER is the most important factor. If RFID READER fails to operate frequency well, it will be difficult to apply RFID technology to work places and manage multi-readers used in a narrow place. This work reveals that making possible multiple readers environment and reporting the state of the entire upgrade are of significant in terms of the system's functions. This thesis studied RFID reader platform with self-diagnosis function.
