Great barcode toolkit Robert Kon Nov We tried leadtools barcode invalif and it helped us to write and read different 1D and 2D barcodes including invalod I found it particularly useful that we could open almost any file format and recognize the barcodes in them.

Great toolkit and outstanding support. I give it 5 stars.
