In many RFID application scenarios the distance between reader and tags is constantly changing with a different velocity. And this change will affect the performance of RFID system. In this paper, a novel scheme named a dynamic RFID performance test system is proposed to find out how movement affects the performance of the RFID system. A new simplified model is proposed to describe these scenarios,...
The rapid changing market is making manufacturing systems increasingly trend to multi-varieties and small-batch production. It drives that strict production operation management in detail is done. In this paper RFID tags are introduced to overcome difficulty to identity important production elements in workshop. A tag data model of production element is proposed, and the architecture and integration...
We propose new methodologies for the authentication of RFID tags along supply chains, exploiting tags equipped with a Physical Unclonable Function (PUF) device. Unlike state-of-the-art approaches that require sharing a large database of challenge-response pairs (CRPs), we achieve a constant amount of shared secret data, oblivious of the number of CRPs and tags to be handled. Such data can be distributed...
Pharmaceutical manufacturing is legally bound and supervised by government. Paper-based and manual pharmaceutical manufacturing systems are time-consuming, manpower-wasting, high-quality-cost and error-prone. This paper presents a Manufacturing Execution System (MES) to control production process on the shop floor. Some new advanced technologies, such as RFID, wireless manufacturing, real-time data...
As the expanding of the production scale, the efficiency and the stability of the manufacturing line begin to dominate the key role in manufacturing industry accompany the material monitor. It is learned that effective and correct operation will save a lot of producing cost. Therefore, in this paper, a monitor and control system framework architecture based on Radio Frequency Identification (RFID)...
In this paper we present an approach to test the security of RFID system. Starting from a division of RFID system architecture, we divide the security of RFID system into three parts: fore-end subsystem security, back-end subsystem security, security caused by malicious software. To each part, several test cases are listed to test security. The key benefit is that this approach can solve the interoperation...
Radio link budget is a determinant factor for the coverage estimation of wireless communication systems. Various studies have been made to model the radio link budget of passive Ultra-High Frequency (UHF) Radio Frequency IDentification (RFID) systems, which operate in dyadic channels. These studies generally either ignore or make simple assumptions on the backscattered-transmission loss due to the...
RFID technology has been widely utilized for the tracking and identification of numerous stationary and moving objects. One of the most challenging RFID applications has to do with the improvement in reliability, scheduling and efficiency of large-scale transportation infrastructure. As an example, Radio Frequency Identification (RFID) technology in UHF frequencies (840–845MHz and 920–925MHz) is one...
This paper presents a Decision Support System framework based on Constrain Logic Programming and offers suggestions for using RFID technology to improve several of the critical procedures involved. This paper suggests that a widely distributed and semi-structured network of waste producing and waste collecting/processing enterprises can improve their planning both by the proposed Decision Support...
A fully integrated HF multi-standard RFID transceiver for compact mobile terminals is proposed. Considerations for multi-standard are concerned in each part of the proposed transceiver and all of them are implemented as digitally-controlled components. A transmitter controls its modulation index with a mode selector and its emitting power to tags with a power controller, thus covering various standards...
RFID is one of the contemporary technologies that has the potential to enable improved data gathering and cross-companies integration, and thus achieve cost efficiency. However, RFID has not yet become primary approach to collect data from the supply chain activities. This is partly due to (relative) high cost of implementation, partly due to technical deficiencies, as well as cross-company systems...
In this paper we introduce an UHF-RFID reader system built to serve as a multi-purpose reader for UHF-RFID applications. The structure of the reader itself is highly flexible to be able to include several standards. The intended use of the reader, however, consists in the support of navigation systems for the indoor environment. Assuming that arbitrarily distributed RFID tags, containing their exact...
Circularly polarized RFID tag antenna is designed based on the simplified human hand model in terms of Ansoft HFSS simulation. In the design, the influence of the human hand is effectively considered. At the same time, the rectangle structure of the tag antenna can eliminate the influence of random position when we grasp the tag. Hence this antenna can be implemented in the RFID tickets. Simulation...
In this paper we present a novel active radio frequency identification system consisting of transponders with low complexity, low power consumption, and long system reading range. The transponder's low complexity and small circuit integration area indicate that the production cost is comparable to the one of a passive tag. The hardware keystone is the transponder's radio wake-up transceiver, which...
Radio Frequency Identification (RFID) is generic term for technology employing radio waves for detecting objects. RFID has wide application in payment systems, access control, asset tracking and other areas as many companies are using and developing the technology's potential. As RFID develops, it imports some new elements, one of which is Java technology. Java now can be seen in any links from RFID...
As a non-contact automatic identification technology, radio frequency identification (RFID) technology plays an increasingly important role in social life. But the existence of potential safety problems has restricted the widespread application of RFID technology. In order to deal with the design challenges in the calculation of speed, communications capability and storage space to the low-cost radio...
An RFID authentication scheme based on ring signature was proposed. The Tag and back-end database were properly configured with different workloads, aiming to ensure the Tag's privacy and realize the authentication. This scheme only needed two bilinear pairing computations for any group size in the back-end database and no computation in Tag in order to enhance the network efficiency, which was suitable...
Electronic Product Code Discovery Service (EPCDS), a well known and under developed standard provided by EPCglobal Network, is playing a crucial role in handling of the product visibility data throughout the supply chain. Recently, EPCDS now has a centralized data repository in which the data are registered by multiple data owners. To protect the privacy of the centralized data, this paper proposes...
