Hi, everybody, I am implementing an barcode API and want to generate a EAN 128 barcode as below: BarCode barcode = new BarCode(); barcode.setType(IBarCode.EAN128); barcode.setData("(00) 00030017 000043516"); The correct check sum should be 8, however, the API output 2. Is there something wrong? Can I output EAN 128 without check digit?

The data you encode should be calculated with 10 Module Algorithm. If you sue the 103 module algorithm, there must be change to the Check Sum Class with different results.

Maybe, the check digit calculation does not take the FNC1 start character into account, but it should do.

There must be a bug with the barcode generator you use as above saying. A mature and reliable EAN 128 barcode generation component is required for you to quickly and exactly calculate the check sum for the generated EAN 128 barcode image.

For hiding the EAN 128 check sum digit, you may use the following code for the EAN 128 barcode image without checksum: barcode.setdisplayCheckSum(false); Hope I helped.
