There is no human readable interpretation for the check digit. The recommended minimum symbol height for manual scanning is 5. The quiet zones must be at least 10X wide, where "X" is the current X dimension. Such barcodes include FNC1 characters, application identifiers, check digits, and extra spaces and parentheses in the human readable interpretation characters.

Following is an explanation of the two most common barcode families as well as an explanation of some of the common barcodes associated with them. Barcodes allow us to precisely record and reference data. They give us the ability to encapsulate everything from a very small amount of data such as an item SKU to very large collections of information such as a shipping manifest or binary strings.
It is important to understand barcode types to match them properly to your application. Some barcodes are best suited to retail while others for warehousing and manufacturing. The following information will help you understand 1D and 2D barcode types and identify the versatility of each as well as the advantages and disadvantages of both types. Both 1D and 2D barcodes encode data that is decoded using a laser or other imaging device, but that is where the similarities stop.
The methods used by each barcode type for storing that data varies greatly between these two symbology types. One-dimensional barcode data is stored in linear, parallel lines that vary in width and spacing. Their linear format makes them better suited for smaller amounts of information since larger values would make the barcode too wide to display properly on a screen or printed page.
Changing the density of 1D barcodes can help to shrink a barcode to display more data on a page or screen but at the cost of reduced resolution and the ability to scan properly. Two-dimensional Barcodes : More data in less space.
They are able to maintain a fairly small size while holding much more data than linear 1D barcodes. Decoding these requires a reader capable of decoding 2D barcodes. Most retail products sold in North America feature this barcode while retail products sold outside of North America feature an EAN barcode.
The UPC contains a unique 12 digit code that a retailer requires to record and lookup the information for the item in their inventory or point of sales system.
