The DHL barcode scanner works by using a laser or camera to read the barcode on a package. When the scanner is activated, it emits a laser beam or takes a picture of the barcode, which is then decoded by the scanner's software.

This allows DHL to efficiently and accurately manage the movement of packages within their network.
