Barcode is a geometric pattern, usually vertically lines, which are used to scan and track property or goods. Although they were first used to track railroad cars, they became even more popular when they were adopted by commodity products for supermarket use. 2 common kinds of barcodes are the Universal Product Code (UPC) and International Standard Book Number (ISBN), which must be applied for through official agencies to validate a product before it can be sold. Barcodes can be used to keep track of retail inventory, or they can be used privately to code and track collections or goods. Read more to find out how to create a barcode.
