For UPC-E barcode, usually there are 8 digits printed on the barcode label. The first digit is UPC-E number system, valid values are 0 or 1. The next 6 digits are UPC-E data, and the last one is checksum.

Our library will return 6 digits data and the last one checksum. Developer should use the first 6 digits as UPC-E data, according to UPC-E specification.

For the above barcode image, 0 is the number system, 123450 is the UPC-E data, and 5 is the checksum. Our library will return 1234505, plus suppliment barcode 12345. So the final output will be 123450512345.
