Barcode Formats
A barcode format describes how the data in a barcode is to be visually represented. There are many barcode formats available, many designed for a specific industry, each with its own specification and intended use cases, benefits and limitations. For example, the UPC is used in retail for inventory management and to streamline the checkout process while eliminating the opportunity for human error occurring.
