RFID Toys

ExtremeTech wants to introduce you to RFID basics, and teach you how to build your own ultimate RFID projects in a new book from the ExtremeTech Book Series. Get started with RFID by reading an excerpt from the book: RFID Toys.

Radio Frequency Identification—RFID—is used throughout the world, mostly by big business, but that's changing. It's becoming a technology well within reach of the everyday hobbyist. Unfortunately, the majority of what you'll read about RFID today mostly deals with the process of implementing RFID throughout businesses large and small, for the purpose of inventory management, personnel management, and supply-chain automation. There are books about RFID that contain every piece of technical information you could ever want to know regarding radio energy theory and signal propagation. Here, we won't go that deep, but we'll explain the concepts of RFID and show you that it's not just for big businesses and show how you can build great projects on a hobbyist's budget.  more
