Barcode scanner, a device used to read and decode barcodes, which are optical representations of data.
Function: Barcode scanners translate the visual information in a barcode into electrical signals, which are then decoded into human-readable data and sent to a computer or other system.
Components: They typically consist of a light source, a lens, and a light sensor to capture the barcode image, along with decoder circuitry to interpret the data.
Applications: They are widely used in various industries for tasks such as inventory management, retail sales, logistics, and asset tracking.
Features: Modern barcode scanners often offer features like wireless connectivity (Bluetooth, 2.4G), different trigger modes (including hands-free), and compatibility with various operating systems.
