A barcode scanner reads and decodes barcode information. It works by emitting light onto the barcode, measuring the reflected light, and converting it into digital data.

There are handheld, fixed-mount, and wireless barcode scanners. Handheld scanners offer flexibility, fixed-mount scanners are stationary for automated tasks, and wireless scanners provide mobility for large-scale operations.

For example, a handheld scanner is ideal for a cashier worker with limited reach. Fixed-mount scanners are normally used on a production conveyor belt scanning large items, or somewhere like a supermarket self-checkout. Wireless scanners can be used by a warehouse, retail, or hospitality worker, which can aid them in scanning inventory, or collecting data.

Yes, many barcode scanners are designed to integrate seamlessly with various business systems, including inventory management and point-of-sale software, enhancing overall efficiency.
