Bar Code & Check Digits


I want to know if you calculate automatically the check digit used by Bar Code readers. If I give you the bar code to create will you automatically create check sum and add it to bar code image that you create.

Hi Nikolaos,

Thank you for considering Aspose.

Yes, Aspose.BarCode.BarCodeBuilder class automatically calculates the check digit and adds it to the generated barcode symbol. Please check the snapshot attached. EAN-13 symbol is produced with below source code lines,


var builder = new Aspose.BarCode.BarCodeBuilder(“123456789012”, Aspose.BarCode.Symbology.EAN13);

If you like, you can evaluate the product yourself. Please proceed to download the latest version of Aspose.BarCode for .NET and test it against your requirement. You may also check our online documentation for Programmer’s Guide.

In case you have further inquiries, please feel free to write back.
