An RFID Reader is a device that uses radio waves to communicate with RFID tags. These tags contain small chips that store information, allowing the reader to identify and track objects without direct contact. RFID technology is commonly used in various applications, such as inventory management, access control, and supply chain tracking. The reader emits radio signals that activate the RFID tags within its range. Once activated, the tags send back their stored information to the reader, which processes and displays the data. This technology enables quick and efficient data collection, making it valuable in many industries.
