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 information about the object. When the tag comes within range of the reader, it sends the data wirelessly, allowing for quick identification. RFID is commonly used in various industries, including retail, logistics, and healthcare. For example, it helps manage inventory by tracking products in real-time, improving efficiency and reducing errors. This technology enhances supply chain management and enables better asset tracking.
