Radio Frequency Identification (RFID) is a technology that uses radio waves to automatically 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, while the reader emits radio waves to communicate with the tag. RFID is commonly used in various industries, such as retail, logistics, and healthcare, to improve inventory management and enhance security. By enabling quick and accurate data collection, RFID helps businesses streamline operations and reduce human error, making processes more efficient.
