Recently, many enterprises are interest in implementing Radio Frequency IDentification (RFID). However, they have some difficulty in implementing RFID because of incompleteness of RFID technology and uncertainty of Return on Investment (ROI). Even though usefulness of RFID are recognized, many enterprises are just interested in planning of RFID rather than implementation of RFID. Among successful factors of RFID implementation, Information Technology (IT) capability is the most important one. If enterprises have systematic IT capability, it would make positive attitude to implement RFID. In addition, it will provide trust about RFID and promote adoption of RFID implementation. This study, therefore, empirically analyzed the relationships of trust, attitude, IT capability, and intention to RFID adoption using Partial Least Squares (PLS) approach. The result show useful guidelines and practical implication in implementing RFID.

This study reviews previous studies about the effects of RFID capabilities on strategic supply chain competence and business performance in the Chinese context. This study introduces a new perspective that measures the degree to which RFID capability levels contribute to business performance. Such an assumption is based on the fact that companies build their own capabilities through RFID capabilities and that these capabilities provide a competitive advantage for enterprises. Data on all sorts of logistics, distribution, and manufacturing companies that introduced RFID system in China were collected for data analysis. This study analyzes the structural equation modeling using Smart-PLS 2.0 program. This study confirms that internal reliability, convergent validity, and discriminant validity are satisfied. The hypothesis test result on the relationship between RFID capacity and strategic supply chain competence and strategic supply chain competence and company results is partially adopted. This study aids in establishing a RFID system construction strategy to enhance supply chain competence by suggesting guidelines for the successful introduction of RFID system through identifying the causal relationship between RFID capacity and strategic supply chain competence. This study also suggests the influence of RFID competency on visibility, agility, flexibility, and collaborations.

One of the important performance issues in large-scale RFID systems is to resolve collisions among responses from RFID tags. Considering two do facto anti-collision solutions, namely the binary-tree splitting algorithm and the Slotted-Aloha algorithm, we propose to use multi-packet reception (MPR) capability to enhance the RFID tag reading rate (i.e., throughput). MPR allows an RFID reader to receive multiple reponses transmitted by tags at the same time. We analyze the effect of MPR capability in the above anti-collision algorithms, which is also validated by simulation. The analysis and simulation results show that RFID reader antenna design and signal separation techniques play an important role in improving RFID system performance with MPR capability.

Recently, traceability systems are introduced as a new food safety information system. To trace food products efficiently, they must have an automatic identification capability at the individual product level. This capability can be gained through RFID technology. But there is not yet any performance evaluation tool on RFID-based traceability systems (RFID-TS). This study developed an evaluation tool of RFID-TS. To develop the tool, this study considered the objective and the components of RFID-TS as their performance constructs. According to Churchill's paradigm, the tool was established through two stages. The final evaluation tool consisted of four constructs (risk, operational benefits, IS (information system), and network) and nine sub-constructs. Among the four constructs, risk and IS were found as the most important performance constructs through regression analysis. Among the nine sub-constructs, service (which belonged to the IS construct) and economic risk (which belonged to the risk construct) were found as the most important performance sub-constructs.

RFID(Radio Frequency IDentification) systems is a wireless frequency recognition technology that can be used to recognize, trace and identify people, things and animals using RFID. Recently, RFID systems have emerged as new forms of interorganizational systems(IOS). Because of their capability for real-time identification and tacking over large distances, some believe that RFID systems will fundamentally change the my companies do business. The purpose of this study is empirically examined RFID systems adoption for u-business. To achieve this purposes, we were collected 72 questionnaires from Korean companies. In this study, RFID systems adoption was influenced by top management support, information systems maturity, competitive pressure, trust perceived advantage of u-business, compatibility of RFID tag. However, firm size, cost exercised power, did not affect significantly on RFID systems adoption. In the conclusion, study's limitations md implications treated.

Adoption of RFID has become widespread including logistics, drug supply-chain, and healthcare. To adopt RFID, we need to evaluate performance and feasibility of RFID S/W such as EPC Information Service (EPCIS), which demands a variety of test datasets of RFID business events. This paper proposes a novel method for creating RFID business events dataset by means of the simulation of RFID infrastructure. Proposed model provides a flexible representation capability since this is based on well-known petri-net. In addition, it can also be useful when determining adoption of RFID as it supports simulation of RFID environment.

One of the key issues in implementing RFID systems is to design anti-collision protocols for identifying all the tags in the interrogation zone of a RFID reader with the minimum identification delay. In this paper, Furthermore, in designing such protocols, the limited resources in tags and readers in terms of memory and computing capability should be fully taken into consideration. we first investigate two typical RFID anti-collision algorithms, namely RFID Gen2 Q algorithm (accepted as the worldwide standard in industrial domain) and FAFQ algorithm including their drawbacks and propose a new RFID anti-collision algorithm, which can improve the performance of RFID systems in terms of tag identification time considerably. Further, we compared performance of the proposed algorithm with Q algorithm and FAFQ algorithm through computer simulation.

In this paper, different RFID tag types compliant with UHF frequency based RFID system were chosen to build RFID tag embedded concrete blocks. Then, by placing the tags in systematically varied depths of a concrete block, we could measure the RF signal attenuation pattern as the performance indicator of a specific concrete embedded RFID system. Experiments show that the concrete mixing ratio makes no significant difference in tag detection performance level. The significance of the developed RFID system lies in its capability of eliminating GPS's error and shadow area as well as providing smart infrastructure for supporting truly pervasive ubiquitous computing applications especially in outdoor environment.

In today's hyper-competitive business environment, Radio Frequency Identification (RFID) technology is expected to enhance the operation efficiency of supplying chain management in both manufactures and retail industries. However, the widespread deployment of RFID tags may create new threats to user privacy, due to the powerful tracking capability of the tags. Many authentication protocols for RFID have been proposed. They are helpful preventing passersby being scanned to determine what articles they are carrying. However, most of them would not prevent the bigger physical tracking problem of RFID, especially when being tracked by the 'constellation' of products they carry. We proposed this RFID scheme to prevent these tracking problems.

The RFID (Radio-Frequency Identification) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. Some RFID tags have been used in severe environment of temperature ranged from $200^{\circ}C$ to $250^{\circ}C$ for a long time and may cause serious problems such as signal error, short life cycle and explosion. Conventionally, the RFID tags for high temperature applications consisted of Fe-alloy housing part, ceramic powder and RFID sensor. However, it has disadvantage of heavy weight, signal noise and heat shield capability. In this study, we newly applied the aluminum porous materials fabricated by polymer leaching process into RFID tags in order to improve heat shielding ability, and compared the properties of RFID tag inserted by aluminum porous with the conventional one.
