Detailed explanation-1: -Laser barcode scanners use a visible and repetitive “flashing” laser light beam, commonly used to track inventory and to enter purchases into a computerized management system. The scanner is a wonderful tool for providing fast and easy customer service in places like supermarkets and restaurants.
Detailed explanation-2: -Barcodes are just a way of presenting a basic amount of information, so you simply type the item number you want into your field service software or barcode printing software and out comes the barcode version of that number. Once you have the labels, you’ll put them wherever you keep your inventory.
Detailed explanation-3: -Decide which format of barcode is best to use. For inventory management, a code 39 or 128 with a simple alphanumeric format is usually sufficient. If you’re barcoding very small items, you’ll notice the Code 128 is more compact and so possibly better suited for the job.
