In this final segment of Chapter 2 from 'How to Cheat at Deploying and Securing RFID,' we finally pull it all together with a summary of the chapter and a glossary of key terms used throughout the article. The entire chapter--The Physics of RFID--provides a basic understanding of the physics of RFID communications and the characteristics that affect system performance during an RF wave's journey.
The readers and tags in an RFID system communicate with each other through RF waves. Encoding the data (to be communicated) into an RF wave (carrier signal), the emission of the RF wave by antennas, and the propagation of the RF waves between the antennas are governed by underlying physics principles.
