      • Evaluation of a Radio Frequency Identification (RFID) Library System: Preliminary Results

        Paul Golding,Vanesa Tennant 보안공학연구지원센터 2008 International Journal of Multimedia and Ubiquitous Vol.3 No.1

        The literature has indicated that libraries in developed countries are fast growing early adopters of Radio Frequency Identification (RFID) technology. The adoption of RFID in supply chain has reported superior growth, spurred by mandate compliance from global retailers such as Wal-Mart and Target. Numerous tests have been performed in a variety of supply chain environment to determine the performance requirements, physical characteristics and limitations to achieve a near 100% read rate. However, the literature is sparse on reports of performance testing in a library setting, and results from supply chain testing should be reluctantly applied to other environments. Based on the above, this study addresses this gap in the literature with the execution of test cases to examine the operational efficiencies of the inventory reader and the self-check station. The study was conducted at a university library with a test sample of 200 books of different types. The factors examined include tag placement, reader orientation sensitivity, read distance, and metal and other possible sources of electromagnetic interference. Each test case was executed repeatedly and the accuracy rate was recorded. Additionally, a spectrum analyzer was used to monitor possible sources of interference. The preliminary findings suggested that mobile phones and wireless computers have no effect on the performance of the self-check station or inventory reader. In addition, the preliminary results also suggest that metallic shelves affect the performance of the inventory reader with reduced read rate accuracy.
