The item-level tagging is one of the main challenges of many application scenarios. Among these, the pharmaceutical supply chain represents a very interesting case where the new auto-identification technologies, based on RFID and EPCglobal, will play a very import role. The authors present practical experiences gained from a recent research project on the item-level traceability in the pharmaceutical...
A chipless tag RFID reader is presented for short range applications. The RFID reader is comprised of a digital section, RF section and cross-polarized reader horn antennas. The reader horn antennas are used to transmit and receive data to and from the chipless tags respectively. The chipless tags have unique spectral signatures which correspond to resonances present at different frequencies in the...
RFID has been widely developed during these years, and has massive size of the market. However, the security of RFID communication faces with many challenges during its development. In order to strengthen the security as well as reduce the power consumption and manufacturing cost, this paper researches and implements a low-power and high-security RFID authentication system. For the sake of the security...
The purpose of this paper is to study the influences of technological, organizational and environmental factors on the acceptance of RFID in China based on the technology-organization-environment framework. The concept of RFID acceptance is defined as a psychological status to intend to use RFID. The data came from a questionnaire survey in China, and 144 samples were analyzed. The analysis shows...
This paper presents a novel approach that uses the passive radio frequency identification (RFID) technologies to automatically classify tagged objects in a noisy environment and detect their motion status in a real-time manner. We use the relative variance of response rate from the RFID data and propose an extended Hidden Markov Model (HMM) to annotate and an online Viterbi algorithm to decode the...
Radio Frequency Identification (RFID) is emerging as a popular technology for automatic data collection and identification, which can be broadly applied to nearly everywhere, such as library, mass transit, healthcare, E-passport, and supply chains. However, it also brings many security vulnerabilities and threats. Much of the early research in RFID security has been predominately focused on studying...

Radio frequency identification (RFID) is a wireless communication technology that provides automatic identification and data collection. In RFID systems with a large number of tags, many tags respond to the reader at the same time. Thus, enhanced anti-collision algorithms are required to have a fast multiple tag identification process. Anti-collision algorithms can be classified as probabilistic (eg...
In this paper, we present the Intelligent Binary Tree Search anti-collision algorithm (IBTS). It is an optimized algorithm based upon a Dynamic Binary Tree Search anti-collision algorithm (DBTS). Our performance evaluation shows that IBTS surpasses other existing DBTS algorithms. According to our simulation results, the total identification time of IBTS algorithm is reduced by nearly 50% for 50 tags...
Adopting an innovative technology often requires extensive intelligence research. A major value indicator for RFID Technology adoption is how the potentials of RFID can translate into actions to improve business operational efficiency [1]. This paper presents a Local Association Network (LAN) approach to developing RFID enabled visibility systems for body tagging. On site testing validates the proposed...
Photonic crystals have been widely used in the microwave fields for their valuable electromagnetic properties. In order to achieve the application of low-frequency microwave photonic crystals, according to local resonance theory of band-gap structure and equivalent circuit model, we do the research from two aspects: reducing the cell size and improving the band-gap width. This paper proposes a slotted...
With the growing success of the mobile computing devices, such as laptop computer, third generation mobile phone, personal digital assistant, many current and emerging distributed applications present challenging problems to the RFID complex event processing architecture. The traditional architecture of central complex event processing should be reconstructed and the new architecture should show a...
For some circuitry in Technology of Power Electronics, which can not be explained by the existing theory of circuitry, we should recur to the theory of electricity and electromagnetism, basing on Maxwell Equation and some existing theories of electromagnetism, which are deduced by Maxwell Equation. So as to explore new theory for eerie switch circuit in Technology of Power Electronics and establish...
Supply Chain Monitoring (SCMo) systems are able to capture, monitor and provide correct real-time state information about physical activities in supply chain processes for Event Management, which improves efficiency and effectiveness of Supply Chain Management (SCM). Unfortunately, due to various logistic application scenarios, SCMo systems are complex and expensive to build. This paper proposes a...
