Nowadays, the advanced technology of wireless communication technology has been studied using the tax system. Wireless communications technology logistics management, inventory management, are widely used in the field of port management. Especially, RFID technology, import and export business of logistics costs in the distribution has been hailed as the technology to do. In this paper, logistics information system components, RFID technology is one of the proposed algorithm using the intelligent customs management. Moreover, in this paper, goods purchased from abroad, using the phone anywhere at any time simply to calculate the tariff proposed simulation.

RFID 기술은 각 사물에 전자태그를 부착하고, 사물의 고유 ID를 무선으로 인식하여,해당 정보를 수집, 저장, 가공, 추적함으로써 사물에 대한 측위, 원격 처리, 관리 및 사물간 정보교환 등의 서비스를 제공하는 기술이다. RFID 기술은 칩, 태그, 리더, 미들웨어 및 응용 서비스 플랫폼으로 구성되고 유무선 통신망과 연동되어서 사용된다. RFID기술은 사람 중심(anyone)에서 사물 중심(anything)으로 정보화의 지평을 확대시킬수 있는 핵심 기술로 부각되고 있으며, 유비쿼터스 센서 네트워크로 발전될 전망이다. 본 고에서는 900MHz 대역을 이용하는 수동형 RFID 시스템과 433MHz 대역을 이용하는 능동형 RFID 시스템의 주요 구성 요소와 관련 기술 동향 및 전망을 알아본다.

Although current RFID technology can provide wide advantages in food industry, most food companies do not consider widely adopting this technology yet. This paper presents analysis of how the effective implementation of RFID systems in food industry. To Measure the affecting factors, 19 items from Ketinger & Hackbarth, ABI Research, RFID Institutes and Researcher are selected. The validity and reliability of a questionnaire were examined through factor analysis and regression analysis was done by using the introduction of RFID systems and an achievement of ROI(Return On Investment) as dependent variables and the 4 factor scores from the factor analysis as independent variables. The results show that 2 factors are not only important in the introduction of RFID systems but also 3 factors also important for an achievements of ROI in particular.

The mobile RFID (Radio Frequency Identification) is a new application to use mobile phone as RFID reader with a wireless technology and provides new valuable services to user by integrating RFID and ubiquitous sensor network infrastructure with mobile communication and wireless internet. However, there are an increasing number of concerns, and even some resistances, related to consumer tracking and profiling using RFID technology. Therefore, in this paper, we describe the security analysis and implementation leveraging globally networked mobile RFID services which complies with the Korea's mobile RFID forum standard.

This paper is to present map building of mobile robot using RFID (Radio Frequency Identification) technology and ultrasonic sensor. For mobile robot to perform map building, the mobile robot needs its localization and accurate driving in space. In this reason, firstly, kinematic modeling of mobile robot under non-holonomic constrains is introduced. Secondly, based on this modeling, a tracking controller is designed for tracking a given path based on backstepping method using Lyapunov function. The Lyapunov function is also introduced for proving the stability of the designed tracking controller. Thirdly, 2D map building is performed by RFID system, mobile robot system and ultrasonic sensors. The RFID mobile robot system is composed of DC motor, encoder, ultra sonic sensor, digital compass, RFID receiver and RFID antenna. Finally, the path tracking simulation results and map building experimental results are presented to show the effectiveness of the designed controller.

Radio frequency identification system (RFID) is an automatic technology and aids machines or computers to identify objects, record metadata or control individual target through wireless waves. Connecting RFID reader to the terminal of Internet, the readers can identify, track and monitor the objects attached with tags globally, automatically, and in real time, if needed. This is the so-called Internet of Things (IOT). RFID is often seen as a prerequisite for the IOT. This paper surveys the technologies of RFID and IOT, discusses the applications and challenges of RFID technology used in IoT.

An RFID system consists of radio frequency tags attached to objects that need to be identified and one or more electromagnetic readers. Unlike the traditional bar code system, the great benefit of RFID technology is that it allows information to be read without requiring contact between the tag and the reader. For this contact-less feature, RFID technology in the near future will become an attractive alternative to bar code in many application fields. In almost all the 13.56MHz RFID systems, FSA algorithm is used for identifying multiple tags in the reader's identification range. In FSA algorithm, the tag identification time and system efficiency depend mainly on the number of tags and frame size. In this paper, we propose a tag number estimation scheme and a dynamic frame size allocation scheme based on the estimated number of tags.

This paper presents a novel collided tag signals's periodic characteristic based radio frequency identification (RFID) tag collision detection method for the ultra high frequency (UHF) RFID. The proposed method utilizes that periodicity of tag signals is maintained even under tag collision. In the proposed method, the correlation between received signal and reference edge signal is used. Simulation result shows that the detection performance using the proposed method is about 10 dB better than that of existing method. In addition, the detection performances with different magnitude difference, phase difference, delay, number of tags are analyzed.

RFID(Radio frequency indentification) technology, that the reader detect the tag information attached on the objects without contact, is considered the kernel of realizing tile Ubiquitous Sensor Network. Particularly, because there are lots of tags(which the reader have to detect) in the UHF RFID system(that is applied at the Logistic & Distribution industry). In the UHF RFID system the negative effects, we called the tag-collision, may occur and we should solve these effects. So, in the EPCglobal Gen2 protocol they present the Slotted Random Anti-collision algorithm to prevent the tag-collision effect. In this paper, in order to minimize the tag-collision effect and bring on the system efficiency, we propose the Power Increasing Method that controls the transmission power of the reader depending on the environment and verily the improved performance.

Ubiquitous Computing owes Internet and development of computer network and appeared. RFID (Radio frequency Identification) technology is noted by point technology to realize this. However, PML that present in Auto-lD Center is defined point part to describe information of object, and necessary part is to use defining extension separately in actuality application. So that can define object type that can be used for electron tag data processing in RFID application service because do fetters to Auto-lD Center's PML Core in this treatise hereupon and apply in physical distribution circulation service field, designed object information data model.
