RFID, Radio Frequency Identification, technology is a contactless automatic identification technology using radio frequency. For this RFID technology to be widely spread, the problem of multiple tag identification, which a reader identifies a multiple number of tags in a very short time, has to be solved. Up to the present, many anti-collision algorithms have been developed in order to solve this problem, and those can be largely divided into ALOHA based algorithm and tree based algorithm. In this paper, two new anti-collision algorithms combining the characteristics of these two categories are presented. And the performances of the two algorithms are compared and evaluated in comparison with those of typical anti-collision algorithms: 18000-6 Type A, Type B, Type C, and query tree algorithm.

RFID (Radio Frequency Identification), which is a kind of the electronic tag, is a wireless access device using the radio frequency for recognizing the ID information. It has a variety of application such as the bus card, gate access card, distribution industry, and management of construction materials. The performance and size of RFID depend on the penetrability, recognition ratio, memory size, multi tag recognition, external pollution dust, and exterior impact, and RFID requires the packaging to protect itself considered above factors. Recently, RFID is diversely employed to effectively manage construction materials and the RFID packaging, which is robust to the external impact, is required to attach RFID on construction materials. In this paper, we propose the construction material RFID packaging designed to be robust for the external impact and to be practicable for change of the broken RFID. For the change of RFID, we separate the cast and body of the packaging. Also, we present the detail drawing for the proposed construction material RFID packaging and implement the performance evaluation of the packaging manufactured using 3D printer.

Thesis is about RFID(Radio Frequency Identification) technology which is recently in the spotlight of overall industry including physical distribution. Most RFID systems in Korea are imported, and there are also problems in manpower. In order to prevent these kinds of problems, students made to get and easy access to RFID system. The purpose of is to solve the regulation problems. We made an application software to practice RFID system implemented, which have several modules so that it can be easy for users to understand RFID system. We also invented a system which makes student ID to help users understand how RFID system is implemented in real life.

VIP marketing has recently become the main concern in the field of marketing, which could increase customer loyalty and sales through providing customers in the top 20% with customized services. In this study, some cases of RFID (Radio Frequency Identification) technology based VIP channel management are introduced and analyzed in the technology point of view. As a result of case studies, it has been shown what the companies may consider when applying RFID technology in customer relationship management (CRM) and its general scenario. As one of the AIDC(Automatic Identification and Data Capture) technologies, RFID can enable to identify humans or objects with radio frequency and is being widely used to many industrial areas such as logistics, delivery, inventory management, and so on. If this technology is applied to CRM as a new channel for customer management, it will be possible to provide an individual customer with various types of intelligent services customized to his or her spending habits. RFID for CRM channel management is still in its early stages, but it is sure that RFID technology will be an useful tool to manage customers including especially VIP in many businesses and capture important information applicable to marketing campaign in the near future.

In this paper, we compare the accuracy of most representative radio frequency identification (RFID) tag estimation functions in the context of minimizing RFID tag identification delay. Before the comparisons, we first evaluate the accuracy of Schoute's estimation function, which has been widely adopted in many RFID tag identification processes, and show that its accuracy actually depends on the number of tags to be identified and frame size L used for dynamic frame slotted Aloha cycles. Through computer simulations, we show how the accuracy of estimation functions is related to the actual tag read performance in terms of identification delay.

Radio frequency identification(RFID) combined with wireless technology has good potential for structural health monitoring(SHM). We describe several advantages of RFID and wireless technologies for SHM, and review SHM examples with working principles, design and technical details for damage detection, heat exposure monitoring, force/strain sensing, and corrosion detection in concrete, steel, carbon fiber reinforced polymer(CFRP), and other materials. Various sensors combined with wireless communication are also discussed. These methodologies can be readily developed, implemented, and customized. There are some technical difficulties, but solutions are being addressed. Lastly, a surface acoustic wave-based RFID system is presented, and possible future trends of SHM based on RFID and wireless technology are presented.

RFID(Radio Frequency IDentification) is now being applied in the lots of fields as an alternative of barcode system. However, it is restricted within product manufacturing, sales, and delivery parts. In this paper, research results regarding an actual progress of an RFID-based system and its effect are described. In addition, this paper confirms that the RFID-based process of manufacture gives much better return of investment than the barcode-based one. Therefore, the results of this paper are highly expected to contribute to make many people, who might hesitate to replace the barcode and apply RFID system to the process of manufacture, a positive decision.

A low-power Radio Frequency Identification (RFID) system is an auto-identification technology that reads and writes an information of things without physical contacts using radio frequency. It is unescapable against unlawful modification, eavesdropping, tracking, or privacy of individuals because RFID systems use the radio frequency and RFID tags. Therefore we create a key using hash chain between database and tag and this process can prevent above attacks. Also we support the efficiency of proposed protocol using hash function to abate computation.
