The main advantage of a barcode reader is that it improves accuracy by reducing instances of human error. Since barcode scanners provide a more reliable way to read and record product information, employees don't have to manually enter data.
Barcode scanners also enhance inventory control by providing up-to-date and accurate inventory tracking. By automating the process of recording and tracking inventory items, barcode scanners significantly speed it up. They also reduce the amount of time needed to train a new employee. Only a few minutes is required to master the use of a handheld barcode scanner. Despite the fact barcodes are cheap to generate and print, a high initial investment will be required.
