Healthcare industry is one of the largest industries all over the world. Nevertheless, counterfeits and medical errors harm its prosperity. At present, researchers focus more on hospital information system, leaving the whole healthcare supply chain out of account. However, overall-process regulation of the whole healthcare supply chain is essential to overcome the predicament. In this study, PharmaX...
In this work, design aspects, simulation and measured results of thin planar UHF RFID tags suitable for mounting on any platform are presented. Such tag designs are of great importance in UHF RFID where low tag profile in harsh electromagnetic environment is required. The tag antenna is separated by a dielectric substrate of less than 1% of the wavelength, lying entirely above the ground plane. The...
Radio frequency identification (RFID) suffers from collisions when multiple tags respond in the same time. This paper presents Query Tree ALOHA (QTA) anti collision algorithm, improved by using a new tag estimation technique based on signal strength. In addition, by using this technique it is possible to detect when two tags remain in the identification tree and hence acknowledge these tags without...
RFID (Radio Frequency Identification) and WSN (Wireless Sensor Network) are technologies that be widely used and have a profound impact on human society. This paper puts forward a WSID identification platform of heterogeneous network which integrates wireless sensor networks technology, RFID technology, GIS location technology together. The platform uses dual-frequency-and-dual-protocol RFID readers...
The paper presents the design and development of a low cost chipless RFID system for secure near field data transfer. This system is ideal for use in credit cards and similar identification cards which are based on "data transfer by contact" which at present uses the conventional using integrated circuits (IC) or magnetic strips. The system consists of the design of a compatible low cost...
IC industry with the rapid development of science and technology, and product diversification, and reduce the life cycle. How to accurately control the progress of the production line to meet the customer requirement is an important issue. Packaging and assemble is the last process for IC final product. The Wire bond stations are the most variation in the packaging and assemble process. For the purpose...
Consider a situation where one desires to retrieve sensor data from an arbitrary environment via a moving interrogator. Maintenance of street lights and electric apparatus in conduits for example. The fundamental problems with this system have been 1)the trade-off relation between power consumption by sensor and the data retrieval rate for the interrogator, and 2)the data retrieval agility for the...
A transmitter is designed based on a new procedure, which adjusts device parameters for the FCC's mask. The procedure analyzed the effect of the coefficients in the expression of Gaussian impulse to the PSD (power spectrum density). The rising time of the pulse was utilized to make the PSD satisfy the FCC requirement. Then the active device parameters can be determined on the basis of the rising time...
Nowadays Radio Frequency Identification (RFID) transponders operating in UHF band are gaining popularity of applications for their low cost, long operating distance and high data rate. In this paper, a novel baseband processor for ultra-low-power passive UHF RFID transponder complying with ISO/IEC 18000–6B standard is presented. In order to reduce power consumption of the baseband processor, several...
Automated-reading process of an RFID reader can be interrupted due to the relative orientation of the transponder (tag) antenna with respect to the reader antenna. This article proposed a modified revolving magnetic field based RFID reader, which is capable to produce a rotating near field in space. When a magnetically coupled RFID tag placed in the near field zone or read range, the tag can easily...
Radio Frequency Identification, RFID technology having been realized of its potential usages only in recent years is now widely used in multiple disciplinary industries and applications. Major of which include SCM, logistics and retail as well as manufacturing. Another key application area of RFID is its use for localisation or positioning of items and people indoors. However, signal propagation in...
Radio Frequency Identification (RFID) technology not only offers tracking capability to locate equipment and people in real time, but also provides efficient and accurate access to medical data for doctors and other health professionals. However, the reality of RFID adoption is far behind earlier expectation. This study reviews the literature on RFID applications in healthcare based on a formal research...
In this paper, we introduced a new antenna topology for RFID tag that could be implemented simultaneously to support the UHF band of Europe (866MHz-868MHz), the UHF band of North America (902MHz-928MHz), and the microwave band for ISM (2.4GHz to 2.45GHz). The antenna proposed herein was composed of a planar inverted-F and a parasitic inverted-L, both of which formed a small, simple and cost effective...
A novel radio receiver circuit, functioning as a tuned active, detecting antenna, is described. The receiver is suggested to be part of a new radio system with the potential of competing with the range capability of active RFID-tags and, through its low power and long lifetime, with passive RFID-tags. The circuit is outlined and the functionality is verified by simulations and measurements. A 24 MHz...
Security and privacy on low-cost RFID deployments is focusing the attention of researchers due to the progressive adoption by retailers, making the RFID a real ubiquitous technology. Besides the retail sector, other logistics industries are starting to improve their processes with this technology like the postal companies, supposed to be one of the largest RFID sector. This paper is focused on the...
As a core technology, RFID technology has been more and more widely used with the development of Internet of Things. But in current RFID applications, there is a key problem waiting to be solved. That is, how to make the reader read better? For this problem, we propose a method for optimizing the position of passive UHF RFID tags. Firstly, a relative ideal test environment has been built. And then,...
A type of near-field antenna for RFID reader is proposed, which has folded-dipole antenna structure. A parasitic capacitance patch is inserted on the gap between two arms of folded-dipole antenna to adjust the antenna impedance. It's shown by simulation that near-field antenna is efficient to reduce antenna dimension for UHF RFID reader.
In this paper we present a Radio Frequency Identification (RFID) protocol used to wake up and extract the ID of every tag (or a subset thereof) within reach of a reader in an active backscatter RFID system. We also study the effect on tag energy cost and read-out delay incurred when using the protocol, which is based on a frequency binary tree. Simulations show that, when using the 2.45 GHz ISM band,...
