RFID Barcode readers, also known as interrogators, are the workhorses of radio-frequency identification (RFID) systems. These devices act as the bridge between the physical world and the digital realm. They transmit radio waves that nudge nearby RFID tags into action. The tags, in turn, respond by sending back data encoded within their memory. This data can be a unique identifier for a product, information about its location or condition, or even sensor readings. RFID readers come in various shapes and sizes, catering to different applications. They can be fixed to doorways for access control, integrated into handheld scanners for inventory management, or even embedded in windshields for toll booth automation.
