3. How to scan & return supplement barcode data?
For barcode EAN 8, EAN 13, UPC-A, UPC-E, their barcode image may contain 2 or 5 digits supplement barcode, ASP.NET Barcode Reader Control will add supplement barcode data to the main barcode data.
For example, ASP.NET Barcode Reader Control will output data as "123450512345" for above sample image. The First 7 digits "1234505" is UPC-E data, and the last 5 digits "12345" is UPC-E supplement data.
4. More details about UPC-E barcode data
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.
