RFID: Overview
Radio Frequency Identification (RFID): A method for uniquely identifying an object using a tag or module that carries a unique ID number, or code. An RFID system consists of a radio-enabled device that communicates with, or interrogates a tag or label, which contains an embedded single chip processor and antenna. Just like barcode scanners, the"interrogator"or RFID reader can be fixed or portable. The tag itself is an extension of the bar code labels you see everywhere today, only with more intelligence. The advantage of these more"intelligent"systems is that, unlike barcode-based data collection, an RFID system can read the information on a tag without requiring line of sight or a particular orientation. This means that RFID systems can be largely automated, reducing the necessity of manual scanning for exceptions management. Identification can be made using wireless (RF, or radio-wave) connection, meaning no line-of-sight or physical contact is needed. There are many different ways to achieve RFID and many applications including pet ID, identification of parts on an assembly line, tracking goods in manufacturing or retail settings, etc.
