商品簡介
Radio frequency identification (RFID) is most often used to keep people from stealing items from stores, and for that the tag only needs to tell the door that it has or has not been deactivated at the counter--a one-bit tag. The focus here is on more complex tags that can contain much more information, though at this point such tags and systems are too expensive except for high-value applications. Scientists and engineers from Australia, Europe, Asia, and the Americas look at security, middleware, anti-collision protocol, and applications. Among the applications are vehicle identification, tracing the integrity of drugs, detecting sleep apnea, and monitoring the condition of high voltage.
