Book Description
Radio frequency identi cation (RFID) is a rapidly emerging technology that enables au- tomatic remote identi cation of objects. Passive and semi-passive RFID systems can be distinguished from other forms of wireless systems, because the RFID tags (transponders) communicate by way of backscatter. In addition, passive tags derive their energy from the RF energy emitted by the reader. RFID technology can provide a fully automated data capture and analysis system. Compared to a passive RFID system, an open platform semi-passive UHF RFID tag can provide identi cation, security, low-power (compared to a wireless sensor net- work(WSN)), medium range and medium processing speed. However, the eld of semi- passive RFID is still under development, and has yet there are no open development platforms available. This thesis develops a prototype of a semi-passive UHF RFID tag that is compatible with the leading UHF RFID standard EPCglobal Gen 2 Class 1. I alsot has the exible I2C and analog digital converter(ADC) interface, which allows the additional of external analog and digital sensors. The sensor data can be read by microcontroller and stored at memory. Standard reader can get sensor data by sending QUERY and READ command to tag. Test results of our open platform semi-passive UHF RFID tag demonstrated that it can achieve a read rate above 50% when an open platform semi-passive UHF RFID tag is placed four meters from the reader antenna and the reader output power is set to 21 dBm. In addition, the proposed semi-passive open platform RFID tag consumes very little power (4.9 mA in 2V with system frequency set to 8MHz).

Book Description
In this thesis, I present novel circuit designs that convert a Ultra High Frequency (UHF) passive Radio Frequency Identification (RFID) tag into a semi-passive RFID tag. Passive RFID tags are relatively inexpensive to purchase and to integrate into objects and devices. However, in some environments and on some objects the performance of the pure passive tags is not su cient for the intended applications. A semi-passive tag, in comparison to a pure passive tag, has signi cantly greater communication range since the semi-passive tag derives its operational power from an on-tag power source instead of just from an interrogator's communication signal. As a result, semi-passive tags have greater usability in a broad range of applications. My novel circuit designs act as an additional on-tag power source and are intended to be low-cost additions to an existing passive tag operating in the UHF (Ultra-High Frequency) frequency range. Thus, currently deployed tags may be retro tted in the eld as their intended applications change and demand greater communication range. Prototype implementations of my designs were able to increase the read range of a passive UHF RFID tag by up to 39%.

Book Description
UHF Radio Frequency Identification (RFID) is an electronic tagging technology that allows an object, place or person to be automatically identified at a distance without a direct line-of-sight using a radio wave exchange. Applications include inventory tracking, prescription medication tracking and authentication, secure automobile keys, and access control for secure facilities. This book begins with an overview of UHF RFID challenges describing the applications, markets, trades and basic technologies. It follows this by highlighting the main features distinguishing UHF (860MHz-960MHz) and HF (125 kHz and 13.56 MHz) identifications, in terms of reading range, environmental sensitivity, throughput and safety. The architecture of the integrated circuits and the organization of the memory are then described. One chapter is devoted to the air interface protocol aspects, including coding, modulation, multi readers operation and anti-collision algorithms to manage the tag responses. Focus will be put upon the EPC Gen2 protocol adopted in the ISO 18000 Part 6. The core of the book will cover the design and manufacturing issues of RFID tags. The influence of the propagation medium (warehouse, libraries, etc.), the tag close environment (bottles, linens, containers, carton boxes,etc.) and the coupling between tags will also be carefully addressed. The final chapter is dedicated to an industrial use case in the supply chain management, either in the retail inventory or blood traceability.

Book Description
Radio-frequency identification (RFID) is one of the modern names that is becoming increasingly popular, as a result of many years of researches and investigations. Powerful hardware and software tools have contributed, and still do, to place the radio-frequency identification as a popular and widely used technology, from large corporations to individuals, and custom applications. Although RFID offers many advantages over other technologies, it is essential to be aware of its limitations. Therefore, it will be possible to overcome the limitations and to increase its applications. As an example, cost, safety, security, transmissions formats, and international standards are important merit figures of continuous improvement. In this book, we present important proposals that will certainly contribute to the evolution of RFID. Theoretical and practical aspects are presented and discussed by the authors, and thus we invite everyone for a pleasant reading.

Book Description
Radio Frequency Identification (RFID) technology is gaining rapid acceptance as a means to track a wide array of manufactured objects. Currently, RFID technologies have shown promise in transportation (e.g., smart fare cards) and commerce (e.g., inventory control) for a variety of uses and are likely to find many new applications in both military and civilian areas if and when current technical issues are resolved. There are a number of policy concerns (e.g., privacy), however, that will become more crucial as the technology spreads. This report presents a summary of a workshop, held by the NRC at the request of the Defense Advanced Research Projects Agency, to explore many of the key technical and policy issues. Several important themes that are likely to govern expansion of RFID technology emerged from the workshop and are discussed.

Book Description
This lecture provides an introduction to Radio Frequency Identification (RFID), a technology enabling automatic identification of objects at a distance without requiring line-of-sight. Electronic tagging can be divided into technologies that have a power source (active tags), and those that are powered by the tag interrogation signal (passive tags); the focus here is on passive tags. An overview of the principles of the technology divides passive tags into devices that use either near field or far field coupling to communicate with a tag reader. The strengths and weaknesses of the approaches are considered, along with the standards that have been put in place by ISO and EPCGlobal to promote interoperability and the ubiquitous adoption of the technology. A section of the lecture has been dedicated to the principles of reading co-located tags, as this represents a significant challenge for a technology that may one day be able to automatically identify all of the items in your shopping cart in a just few seconds. In fact, RFID applications are already quite extensive and this lecture classifies the primary uses. Some variants of modern RFID can also be integrated with sensors enabling the technology to be extended to measure parameters in the local environment, such as temperature & pressure. The uses and applications of RFID sensors are further described and classified. Later we examine important lessons surrounding the deployment of RFID for the Wal-Mart and the Metro AG store experiences, along with deployments in some more exploratory settings. Extensions of RFID that make use of read/write memory integrated with the tag are also discussed, in particular looking at novel near term opportunities. Privacy and social implications surrounding the use of RFID inspire recurring debates whenever there is discussion of large scale deployment; we examine the pros and cons of the issues and approaches for mitigating the problems. Finally, the remaining challenges of RFID are considered and we look to the future possibilities for the technology.
