Radio frequency identification (RFID) is an undeniable aspect of modern living, being used from logistics, access control and banking to smart cities, smart transportation and as a key enabler of the Internet of Things. Presenting a unique coverage of RFID reader design and engineering, this is a valuable resource for engineers and researchers, aiding in their mission of fulfilling current demand in the RFID space and future development of this technology. Providing a cohesive compilation of resources and step-by-step techniques for full-stack design of RFID readers, the book includes algorithms and source code that can be incorporated in custom designs. Readers are invited to explore the design of RFID readers based on SDR for flexible, upgradeable solutions as well as low complexity techniques for designing low-cost readers. Additionally, the authors provide insight on related topics such as waveform design for improved reading range optimization and novel backscatter modulation techniques.
