Tutorial: How RFID Works, Now and Future

This tutorial presents an overview of how RFID technology works, as well as where the technology is headed.  We discuss today’s proximity cards, NFC devices, and Gen2 UHF RFID tags, emphasizing practical applications.  We will discuss the limits of today’s devices and demonstrate how very far away current RFID performs from the ultimate limits of information transfer and energy harvesting.  We will complete the tutorial with a discussion of future RFID applications that are very different from the logistics-centric world that birthed much of the technology.   This tutorial will be equally relevant for practicing engineers, prognosticating technologists, and budding entrepreneurs.


  • Overview of how HF and UHF RFID readers and tags work
  • Practical examples in Automatic Vehicle Identification (AVI), proximity farecards, Near-Field Communication devices, and more
  • Discussion of the fundamental limits on passive technologies and where RFID will be in 10+ years
  • Future RFID applications: ultra-precise motion tracking, anti-tampering devices, battery-less sensors, and more
