This chapter provided an in-depth discussion of the RFID basics. Admittedly, it covered a plethora of information that might be difficult to assimilate in a single reading. However, a good knowledge of this material is crucial to understanding the technology and applying it to solve real-world challenges. The material in this chapter is used throughout this book to develop related concepts. The reader is advised to revisit this chapter several times until confident of a good grasp of the fundamentals. If you want to dive deeper into the theoretical aspects of RFID technology, consult the RFID Handbook, Second Edition, by Klaus Finkenzeller (John Wiley & Sons, 2003).
