If you try to generate the dataMatrix barcode for the string " SC-BURIT006-12/07/2012-00250 " the produced barcode will lost the last 4 characters.
You can test it in the Demo Applet page.
The same string produce correct barcode with other generator services (e.g. http://datamatrix.kaywa.com/img.php?s=12&d=SC-BURIT006-12%2F07%2F2012-00250 , the images are really different!).
