Radio Frequency Identification (RFID) is a technology that uses radio waves to identify and track objects. It consists of two main components: a tag and a reader. The tag contains a microchip and an antenna, which store and transmit data. When the tag comes within range of the reader, it sends the information wirelessly, allowing for quick identification. RFID is commonly used in various industries, including retail, logistics, and healthcare. It helps improve inventory management, streamline supply chains, and enhance security. By automating the identification process, RFID reduces human error and increases efficiency in tracking items.
