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. The software translates the barcode into a unique tracking number, which is used to identify and track the package as it moves through the shipping process. This allows DHL to efficiently and accurately manage the movement of packages within their network. **
