Radio Frequency Identification (RFID) facilitates automatic identification of items using radio-waves. This technology albeit initially introduced in the 1940s and 1950s, has seen a drastic increase in the number of applications and implementations in the recent years. This work aims to review some of the current developments in this field and to develop a taxonomic framework to classify litera...

The purpose of this study is to compare the organizational adoption factors of Radio Frequency Identification (RFID) between adopters and non-adopters in mandatory and voluntary environments respectively. This paper presents the result of an empirical study that investigates the adoption behaviour of livestock farms in relation to RFID technology adoption in the context of Australia. The quanti...

This paper is an overview of the structure of Radio Frequency Identification (RFID) systems and radio frequency bands used by RFID technology. It also presents a solution based on the application of RFID for brand authentication, traceability and tracking, by implementing a production management system and extending its use to traders. Keywords—Radio Frequency Identification, Tag, Tag reader, T...

Due to rapid progress of ICT, our society is also changing rapidly. A huge amount of information is stored in the Internet servers and shared by all people. It is updated continuously. In such age, we are supposed to keep learning and libraries are supposed to support those people. In order to carry out such missions, libraries are trying to change themselves in order to provide better and up t...

Radio Frequency Identification (RFID) is a common term for technologies using micro chips that are able to communicate over short-range radio and that can be used for identifying physical objects. RFID technology already has several application areas, and more are being envisioned all the time. While it has the potential of becoming a really ubiquitous part of the information society over time,...

Radio Frequency Identification (RFID) technology is emerging as an important tool with applications in a variety of fields. The major concern regarding RFID is the ubiquitous nature of its deployment that extends far beyond the capabilities of any of the tools available today for monitoring any item without an RFID tag. Many of the applications envisioned have a legitimate use. However, this te...

Radio Frequency Identi cation (RFID) authentication protocols are an active and important research topic and many protocols have been proposed. In this paper we examine two hash-function based low-cost authentication protocols, LCAP and OHLCAP, from GNY logic perspective with intention to nd out whether they are convincing that they have achieved their protocol goals. Our analysis shows that LC...

There has been considerable interest recently on developing a system to track items like pharmaceutical drugs or food products. Such a system can help prevent counterfeits, aid product recall, and improve general logistics. In this paper, we present such system based on radio frequency identity (RFID) technology. Our solution provides the means of storing the entire movement of the item from or...

In this paper, Radio Frequency IDentification (RFID) tag set cardinality estimation problem is considered under the model of multiple independent reader sessions with unreliable radio communication links in which transmission errors might occur. After the R-th reader session, the number of tags detected in j (j = 1, 2, ..., R) reader sessions is updated, which we call observed evidence. Then, i...

Privacy protection is increasingly important during authentications in Radio Frequency Identification (RFID) systems. In order to achieve high-speed authentication in large-scale RFID systems, researchers propose tree-based approaches, in which any pair of tags share a number of key components. Such designs, being efficient, often fail to achieve forward secrecy and resistance to attacks, such ...
