The technology that uses radio waves to automatically identify people or objects, similar to barcodes, is called Radio Frequency Identification (RFID). RFID systems consist of tags containing a microchip and antenna that transmit data to a reader via radio waves. This allows for automatic identification and tracking of items without the need for line-of-sight, making it more efficient than traditional barcodes. RFID is widely used in various applications, including inventory management, access control, and supply chain logistics.
