RFID technology has been available for decades, but it is only recently that its application has become a core topic for computing. This book introduces the technologies and techniques of large-scale RFID-enabled mobile computing systems, set in the context of specific case studies.

The book begins with a quick introduction to RFID basics and then discusses the various elements of the topic, using applications such as e-passports, ticketing and supply-chain management throughout. The text explores RFID technology fundamentals, including operating principles, core system components and performance trade-offs involved in the selection of specific RFID platforms. The emphasis is on a practical approach, developing an arsenal of techniques and designs that can be mixed and matched to fit the needs of new systems and applications.

Zusammenfassung
The birth of RFID technology is credited to the 1948 research paper by H. Stockman on Communication by Means of Re?ected Power [109]. After describing the main principle of communication by re?ection and reporting his experiments, he concluded that Evidently, considerable research and development work has to be done before the remaining basic problems in re?ected-power com- nication are solved, and before the ?eld of useful applications is - plored. It turns out that in fact this work required almost 60 years of science and engineering before it was mature enough to ?nd its way into large-scale - plications. This is surprising, as at ?rst glance RFID is a simple technology that is straightforward to implement. And yet, its dull appearance hides great complexity: RFID involves several engineering disciplines, including systems, networking and software development, antenna design, radio propagation, - tegratedcircuittechniquesincreasinglyfocusedonprintedelectronics,receiver design, encryption and security protocols, and materials technology, to m- tion but a few. In this book, I attempt to present the main ingredients for building c- plete network RFID systems, written for a knowledgable computing audience. I hope this book will help practitioners and researchers alike in establishing a robust framework for thinking about rfid. I also hope that the book will help anyone involved with rfid technology to make informed decisions that are appropriate for their particular problem at hand.
