Radio Frequency Identification(RFID) is rapidly growing the attention of many firms as a care technology for their businesses. As RFID moves into the mainstream, it replaces the standard barcodes that is used to identify and track products for a long time. With the intention of gaining competitive advantages, some firms have started the changeover to RFID technology while others have been disinclined to adopt it. Thus, this study examines firms as an attempt to identify key organizational characteristics driving the ear1y adoption and successful implementation of RFID. Results from 228 adopting organizations show Organizational Needs(Ubiquity and Performance Gaps), Technological Factors(Perceived Benefits and Perceived Cost Savings) and RFID Reduced Risk have a significant influence on RFID initiation. In addition, Trust Factors(Institutional Trusts and Inter-organizational Trusts) have a significant impact on RFID Reduced Risk. Finally, Organizational Readiness(Financial Resources and Technological Knowledge) have a significant influence as moderating effects between RFID initiation and adoption. The implications of the findings propose a new theoretical framework for the future IT/IS adoption study and offer suggestions for RFID researchers and practitioners in the development of the technology.

RFID technology is considered as a promising solution to increase efficiency of port logistics. Especially active RFID technology, such as e-Seal for container security, is receiving attention nowadays. If active RFID system is combined with passive RFID and legacy bar-code system overall efficiency of port logistics can be improved However, due to the device dependent control interface of RFID readers, there are many difficulties in making active-passive combined RFID system environment. In this paper, we introduce Smart Reader Interface (SRI) system, which provides a device independent RFID reader interrace to control different kinds of RFID readers by hiding device dependent control interface through adapter architecture which is similar to device driver of conventional operating systems. The key design objectives of SRI are the followings; conformance to the related standard. efficiency in processing, easy addition of an adapter for a new RFID reader. Actually, the implemented SRI system can support various kinds of commercial RFID readers, and through the test carried out not only in laboratory but also in the container terminal in the GwangYang Port, its practicality is verified.

Implementing the automatic identification in supply chain management is essential for effective and efficient process control. Though the GTIN based bar code system is generally used as an automatic identification method in most industries, it can not identify individual item, and is not appropriated for products' reliability and safety management. So the RFID system with EPC is considered as a better solution for resolving those problems. This study reviewed automatic identification code systems and the attributes and characteristics of RFID Gen 2 which became a global standard recently for supply chain management. Particularly, this study analyzed RFID Gen 2 systems' read rates on various conditions including distances between tags and readers and between antennas, condensation, and several packing materials in practical supply chain environment. The results of this study showed that the RFID Gen 2 had high read ratio in practical application and would be adopted as a new automatic identification means for traceability systems.

In the realm of large-scale identification deployments, the EPCglobal Class-1 Generation-2 (Gen2) standard serves as a cornerstone, facilitating rapid processing of numerous passive RFID tags. The Q-Algorithm has garnered considerable attention for its potential to markedly enhance the efficiency of Gen2-based RFID systems with minimal adjustments. This paper introduces a groundbreaking iteration of the Q-Algorithm, termed Time-Efficient Q-Algorithm (SwiftQ), specifically designed to push the boundaries of time efficiency within Gen2-based RFID systems. Through exhaustive simulations, our study substantiates that SwiftQ outperforms existing algorithms by a significant margin, demonstrating exceptional expediency that positions it as a formidable contender in the landscape of large-scale identification environments. By prioritizing time efficiency, SwiftQ offers a promising solution to meet the escalating demands of contemporary Internet of Things applications, underscoring its potential to catalyze advancements in RFID technology for diverse industrial and logistical contexts.

It is very important to protect life, property at sea and marine environments from any pollution. The RFID when it applies a technique, is able to raise the stability of vessel as controling the mobile course and an entrance and exit of the crews as well as previously preventing accident from the vessel. The RFID technique which is applied, It show the effect which prevents an accident in advance, Currently it is used plentifully from physical distribution field and RFID KS domestic Standard $860MHz{\sim}960MHz$ band use the crew has the RFID tag and it will grasp incoming, leaving and movement.

The agro-livestock industry is composed of a complicated supply chain and the customer‘s interest in safety of agro-livestock products is increasing. In order to provide customer with the accurate information about the history of product, and make good use of these information, traceability systems based on RFID technology were implemented and are planned. It is, however, difficult to make the efficient flow of information and to enhance or expand the traceability system because of the lack of the standard of RFID code system. To overcome this problem, we propose a RFID code system for the traceability of argo-livestock products on the basis of ISO/IEC 15459 KKR code system.

RFID(Radio Frequency IDentification) technology is an automatic identification method using radio frequencies between RFID reader which collects the informatin and tag which transmits the information. RFID technology develops passive RFID which transmit the only ID to active RFID which transmit the additional information such as sensing information. there is ISO/IEC 18000-7 as typical standard of active RFID. it is single channel system of 433.92MHz and has limitation of collection of a number of tags. to overcome limitation of collection of many tags, we propose the new 2.4GHz active RFID technology which can use the multi-channel. if reader has multi-interface and uses another channel in each, reader could fast collect the tags. but, if a reader which has many interfaces collects tags through the specific interface, the performance may not improve any more comparing with a reader using single interface. in this paper, we show the fast collection through design and implementation of protocol for load balancing between interfaces in multi-interface RFID reader.

Recently, RFID has emerged as the main technology in the logistic services. When the existing recognition technology based on bar codes brings about lots of problem due to its own limits. RFID becomes the center of attention to solve them. However, RFID is not without any obstacles: companies have their own operating systems, while RFID is developed regardless of each company's special features. RFID middleware system based on web service is expected to remove these obstacles. This paper shows how to operate the middleware based on web service and to lay in the DB the tag informations taken from reader system. Middle assures that companies adopting RFID system for their logistic service are given adaptability to any systems whatsoever, available by way of defining logistic information, tag information and reader information. For this purpose, we implement as the basic web service a middleware system that turns all data into XML(eXtensible Markup Language) of SOAP (Simple Object Access Protocol), the standard data.
