This book introduces the technologies and techniques of large-scale RFID-enabled mobile computing systems. The discussion is set in the context of specific system case studies where RFID has been the core enabling technology in retail, metropolitan transportation, logistics and e-passport applications. RFID technology fundamentals are covered including operating principles, core system components and performance trade-offs involved in the selection of specific RFID platforms. The main text is structured around 3 themes: addressing schemes for RFID tags, complex event processing, identifier resolution and location of associated information services. Written for IT professionals as well as students, the current state of the art in RFID platforms and architectures are discussed. Programming abstractions and practical lessons learnt from real-world deployments are detailed and the book concludes with a brief look at the implications of RFID for privacy protection and for end-to-end security of networked mobile systems.
