RFID 기술은 반도체 기술의 발전과 인터넷의 등장으로 인하여 지난 10여 년 동안 꾸준한 발전을 해왔으며 유통, 물류, 의료, 교육 등 다양한 분야에 적용되고 있다. 이는 향후 수 년 내에 거의 모든 물품에 태그를 부착하게 됨에 따라 유비쿼터스 환경 구축에 큰 기여를 할 것으로 기대된다. 이러한 RFID 기술은 저주파(LF), 고주파(HF), 초고주파(UHF) 및 마이크로파(M/W) 대역의 무선전파를 사용하며 각 대역의 전파 특성에 따라 동물추적, 교통카드, 물품관리, 전자화폐 등 다양한 분야에 선택적으로 적용되고 있으며, 단말기의 형태에 따라 고정형, 휴대형, 모바일 RFID 기술로 분류되고 최근에는 택시안심귀가서비스 등 휴대폰에 RFID 리더 기능이 결합된 모바일 RFID 서비스도 시범서비스를 선보이면서 우리 생활에 파고들고 있다. 또한 항만물류 관리 등과 같이 긴 인식거리가 필요한 능동형 RFID 기술을 포함하여 많은 연구와 실증실험, 시범서비스나 본사업이 이루어지고 있으며 최근에는 파렛, 케이스 단위가 아닌 물품 단위에 태그 부착을 위한 ILT 기술도 속속 선보이고 있다. 본 고에서는 시장전망이 가장 밝은 것으로 알려진 UHF 대역을 중점으로 RFID 기술을 살펴보고 이중에서도 모바일 RFID 기술을 포함한 수동형 RFID 기술, 능동형 RFID 기술 및 이와 관련한 표준화 동향을 알아본다.이를 활용한 응용 시스템에 대하여 간략히 살펴볼 것이다.

Radio Frequency IDentification(RFID) is in the limelight of fields of military, delivery and library management as an alternative or barcode system. However, it is restricted within product manufacturing, sales and delivery. In this paper, we apply RFID technology into process, especially packing process management to gauge RFID applicability. To verify beneficial features of RFID, we simulate RFID-adopted packing process. As a result, we demonstrate the effectiveness of a RFID-based Process Improvement In manufacturing process. The results of performance evaluations demonstrate that the proposed RFID-based Process Improvement reduces the labour time, labour cost and material cost. Furthermore, we analyze the validity of RFID-based Process Improvement by RFID cost.

This paper is an embedded system using the X-Hyper Intel PXA255 ARM CPU that base of the Linux operation system. This system applies tag information reading through RFID leader to Library executive system and designed and embody RFID middleware. The RFID middleware is consisted of RFID module, ARM processor and RS-232 interface. The RFID module is used to be inputted user and books information and RS-232 interface pass information by RFID middleware. Also, This system is embodied by specific Library management system using embedded exclusive use ARM processor. In this paper introduces concept and action principle of RFID middleware and uses Qt/Embedded and embodied manless loaning and return system.

The existing patient monitoring system when the patient want own information. The patient confirm information through the medical institution. But the patient monitoring system based on the U-Healthcare, the patient always confirms own information through the mobile device including rfid reader. The patient need RFID middleware design to provide wanting service when the RFID reader read patient's tag information. The RFID middleware is consisted of RFID module, ARM processor and RS-232 interface. The RFID module is used to be inputted user information and RS-232 interface pass information by RFID middleware. Also, This system is embodied by specific patient monitoring system using embedded exclusive use ARM processor. In this paper introduces concept and action principle of RFID middleware and embodied patient monitoring system that use Qt.

Global interests in RFID are increased and Korean government and companies make an active effort to propagate and spread RFID. Due to the overwhelming advantages of RFID system in comparison with existing bar code system, ripple effects on logistics sector among the utilizing fields of RFID technology are expected to be great, but application of RFID system is lowly progressed unlike the expectation of several experts. Therefore, this research extracts precedent studies on theoretical background, applying fields, promotion condition and domestic/foreign parts of RFID system, factors for operating domestic RFID system and effects and considers the effects of RFID's external variables on easiness and effectiveness of TAM. It confirms the relations of RFID applying effects for companies applying and utilizing RFID and verifies the relations among the effects for application of RFID system, accepting intention of RFID system and applying effects. Based on the results of analysis, it should play a role of good guide for all of companies and institution who will introduce RFID system to all of Korean logistics fields, make policies and systems which promote RFID acceptance nationally and socially and play a role of guide making confident climate for RFID technolog

RFID technology enables companies to precisely manage their inventories at the item level. Recently, due to the wide spread of RFID data-exchange standards, RFID systems are being recognized as separate information systems, each of which is consist of RFID hardwares, a middleware and data repositories, thereby RFID systems become common targets for system integration. In this paper, we proposed an effective integration framework between RFID systems and existing enterprise information systems (EIS). We also surveyed the current state of the RFID-EIS system integration practices. The proposed framework will be helpful for system developers to effectively integrate RFID systems with EIS's.

For realizing ubiquitous computing, many research activities are geared towards various areas including embedded computing, RFID, USN, home networking, context-awareness, and etc. By using the ability of RFID technology to recognize a number of objects simultaneously, more convenient ubiquitous application services are effectively provided. In this case, RFID middleware playing a role as a bridge between RFID reader devices and application services is required as well. In this paper, we propose a method of handling a number of types of RFID reader devices in ALE middleware of EPCglobal. For this, the information of connection and data protocol for a reader device is stored in a database as ontology meta-data, and used to interpret the data read by a reader device. By adding ontology data into a database, even though an RFID device newly emerges, ALE middleware can not only handle the device, but also be effectively extended through reusing ontology data, without any changes in the middleware.

The information flow through RFID techniques such as, standardized EPC and EPCglobal network suggests new change in the method of cooperating and sharing information in the supply chain. Common function should be prepared for communication, security techniques, and business processes based on the EPCglobal standard to introduce efficient RFID techniques. And the standard architecture which can deal with the RFID environment flexibly is quite necessary. Therefore, this paper suggests Enterprise Application Framework (EAF) for developing efficient and secure RFID applications. EAF offers essential services to develop RFID enterprise systems : a communication environment which uses various standard communication protocols, a security function based on PKI, and abstract business services for flexible introduction of RFID businesses. It simplifies the RFID business integration, minimizes the development complexity, and thus EAF is expected to reduce the cost of RFID application development. EAF guarantees constructing secure RFID applications due to PKI-based security mechanism.

Previous RFID systems exclusively manage the tags and readers for each company in individual manner. Thus, RFID system manager should understand and design specifications such as tag events, data format, and etc, based on individual companies. But it is very difficult to know all statements. To resolve theses problems, there has been conceptual research about policy-based RFID service management model that is not restrained from standards of typical RFID systems, including EPCglobal standard, and ISO/IEC standard. However, previous proposed service management model only aimed event management without including device management. Therefore, in this paper, we propose extended device management policy model for giving shape to the proposed policy-based RFID service management model. If the proposing device management policy model is used for device management, we can integrate control management for heterogeneous middleware, diverse RFID devices, and applications for each company. Moreover, we show that the RFID device management policy is translated and processed as an example using the proposing policy model in real-time RFID system.
