Barcode Scanner
A barcode scanner is a hardware device or software application that captures and decodes barcode data, such as UPC or QR codes, into readable text or digital information. It typically uses optical sensors, cameras, or laser technology to read the patterns in barcodes, enabling quick data entry and tracking in various industries like retail, logistics, and inventory management.
Developers should learn to use or integrate barcode scanners when building applications that require efficient data capture, such as point-of-sale systems, warehouse management software, or mobile apps for inventory control. This is essential for automating processes, reducing human error, and improving operational speed in real-world scenarios like shipping, asset tracking, or event check-ins.
