This image depicts a classic linear barcode (e.g., UPC or EAN) printed on a smooth white card, with a vivid red laser beam sweeping horizontally across its bars. The scan line highlights how optical sensors detect reflected light patterns to decode binary information into human-readable data. Such visuals are commonly used to explain point-of-sale systems, warehouse automation, and supply chain tracking.

Used on e-commerce, logistics, and tech education pages to illustrate barcode scanning mechanics; matches user intent for understanding how scanners work, troubleshooting scanning issues, or selecting hardware.
