Abstract
Radio-Frequency Identification Device (RFID) uses radio waves to read and capture information stored on a tag, attached to an object. A tag can be read from several feet away and does not need to be within the direct line-of-sight of the reader to be tracked. A RFID system is made up of two parts: a tag or label and a reader. RFID tags are embedded with a transmitter and a receiver. It can automatically identify a person, a package or an item. Barcodes are really simple and can be easily replicated or counterfeited where as RFID is effective, cheap and secure. So RFID technology has many applications in military zone, inventory management, supply chain, product tracking, transportation, and logistics.
