Radio Frequency Identification (RFID) is a technology that uses radio waves to automatically identify and track tags attached to objects. Each tag contains a microchip and an antenna, allowing it to communicate with a reader device. This system is commonly used in various industries, including retail, logistics, and healthcare, to improve inventory management and streamline operations. RFID systems can operate in different frequency ranges, such as low-frequency, high-frequency, and ultra-high-frequency. The choice of frequency affects the range and speed of communication. RFID technology enhances efficiency by reducing manual scanning and enabling real-time data collection, making it a valuable tool for businesses.
