RFID (Radio-Frequency Identification) is a technology that uses radio waves to automatically identify and track objects. An RFID system typically consists of three main components: an RFID tag or label, an RFID reader or interrogator, and an antenna. The tag contains a microchip with a unique identifier and an integrated circuit, while the reader transmits and receives radio waves to read the information from the tag.
Applications of RFID technology are diverse, including inventory management, access control, supply chain management, livestock tracking, and automated toll collection.
