Radio Frequency Identification (RFID) is a technology that uses radio waves to read and capture information stored in a tag attached to an object or location. In this work, we further exploit this technology to find other applications that differ from its classic one and show how powerful RFID can become in the near future. We present three novel ways of taking advantage of RFID technology that go beyond object identification: an RFID-based anti-counterfeiting architecture for electronic components, a passive displacement sensor using RFID technology and an example of how an RFID tag can perform as an actuator, designing a remote control car driven via RFID. In the first of them (Section 3), we showed the feasibility of using this technology in a PCB production line to authenticate a chip during the pick and place stage, by building a demo where a pick and place machine was linked to an RFID reader. Designs of very small RFID tag antennas are proposed but most likely due to variations in the manufacturing process, they didn't perform as expected. In Section 4 we present an implementation of the principle of RFID tag antenna based sensing by developing a displacement sensor. We conclude that displacement can be mapped to antenna bandwidth and best match frequency. However, for a sensor with higher sensitivity for little displacements, we conclude that a reader with higher RSSI resolution is needed. Finally, in Section 5 we propose two different approaches of controlling a car via RFID technology. Approach A uses the RFID IC writable user memory and Approach B the baseband RFID signal at the tag. In the end we conclude that Approach B is much better as far as time response is concerned.

Radio frequency identification or RFID is a broad-based technology that impacts business and society. With the rapid expansion of the use of this technology in everything from consumer purchases to security ID tags, to tracking bird migration, there is very little information available in book form that targets the widest range of the potential market. But this book is different! Where most of the books available cover specific technical underpinnings of RFID or specific segments of the market, this co-authored book by both academic and industry professionals, provides a broad background on the technology and the various applications of RFID around the world. Coverage is mainly non-technical, more business related for the broadest user base, however there are sections that step into the technical aspects for advanced, more technical readers.
We consider using passive RFID technology beyond its traditional purpose, namely, identification. Instead we consider passive tags being densely distributed in space, providing the infrastructure for distributed, physical information systems. These systems form the basis for continuous pervasive spaces. In such a space, a user perceives services with full continuity. That is, tags are densely distributed in the space. The granularity is so high that a user does not perceive the discreteness. As users equipped with interrogators move through the space, they interact with the tags by reading from and writing to their storages. As a result, information flows through the tags. The resulting services are continuously presented to the user in space-time, since the tags themselves are pervasive. RFID tag multiplicity is a necessary component, and it is the unique supporting solution that enables the design and implementation of continuous pervasive spaces.
Chipless RFID Reader Design for Ultra-Wideband Technology: Design, Realization and Characterization deals with the efficient design of Field Programmable Gate Array (FPGA) based embedded systems for chipless readers, providing a reading technique based on polarization diversity that is shown with the aim of reading cross-polarized, chipless tags independently from their orientation. This approach is valuable because it does not give any constraint at the tag design level. This book presents the state-of-the-art of chipless RFID systems, also providing useful comparisons. The international regulations that limit the UWB emission are taken into consideration, along with design guidance. Two designed, realized, and characterized reader prototypes are proposed. Sampling noise reduction, reading time, and cost effectiveness are also introduced and taken into consideration. Presents the design, realization and characterization of chipless RFID readers Provides concepts that are designed around a FPGA and its internal architecture, along with the phase of optimization Covers the design of a novel pulse generator
Technology is shaping our culture and controlling our lives--for better or for worse. Often, technology's benefits far outweigh its negative impacts, and technological advances can seem boundless. But the scientific-technological worldview tends to override other value systems. Indeed, this technological way of thinking has influenced many contemporary ideas, beliefs, values, habits, and ways of communicating. Furthermore, in addition to technology's well-known environmental impacts, social, aesthetic, and spiritual consequences are now emerging. How can we balance positive physical effects of technology with other ambiguous or negative impacts? Some of the decisions we face have no precedent from which to draw wisdom. For this reason, the resources of Scripture and the Christian tradition must be brought to bear on technological questions: How is technology used and abused today? Does technological progress lead to human progress? How can Scripture help us, both individually and collectively, to manage technology's impact in proactive ways? Swearengen uncovers a comprehensive scriptural mandate for managing technology. On his way to a theology of technology, he evaluates which advances are moving society in directions consistent with God's purposes. Beyond Paradise: Technology and the Kingdom of God aims to provide practical means for assessing technology's influence and for steering technology and its effects toward biblical ends.
Radio frequency identification (RFID) is a fascinating, fast developing and multidisciplinary domain with emerging technologies and applications. It is characterized by a variety of research topics, analytical methods, models, protocols, design principles and processing software. With a relatively large range of applications, RFID enjoys extensive investor confidence and is poised for growth. A number of RFID applications proposed or already used in technical and scientific fields are described in this book. Sustainable Radio Frequency Identification Solutions comprises 19 chapters written by RFID experts from all over the world. In investigating RFID solutions experts reveal some of the real-life issues and challenges in implementing RFID.
