RFID Toys: Cool Projects for Home, Office and Entertainment (repost)

Radio frequency identification now belongs to the masses, and it lets you control all sorts of things. Like access to your front door. Or valuables in an RFID-enabled safe. You can corral your stuff within an RFID-monitored perimeter, or build a shelf that tells you when you're out of hot sauce. This book shows you how, with step-by-step instructions, illustrations, photos, and a list of the tools and tech- nology you need for every project. It even supplies the lowdown on read/write tags and–for the truly extreme–implantable chips.
