I'll let you know what they say... Awesome — I’ve asked our development team to evaluate the alpha (I’m just one of the suits so I can’t offer any meaningful feedback ;-) ).

We will get a new software which scans our documents (extended with the 2D-barcode). It's not yet delivered/installed und so I'm not able to verify it with this software. Again, many thanks for you fast answer and the good news. Thanks a lot for your very fast responce. We will get a new software which scans our documents (extended with the 2D-barcode).

I bet it does. There is more than one way to actually encode a particular message. DataMatrix knows 6 different ways to encode text. I've just tested your example message and it scans well with my barcode scanner. So unless your scanner cannot read the symbol generated by Barcoce4J the difference you reported is not a problem. What I saw during testing is that in some special cases some (not all) barcode readers cannot decode a particular symbol, even though I'm pretty sure the symbol I generated was correct. But having implemented the specification I can say that ISO/IEC 16022:2000(E) is not unambiguous in some places. But does the symbol generated by Barcode4J scan correctly with your scanner?

I've tried the datamatrix encoding and encoded small texts. Iit works fine. If I encode texts with length around 30 character I get not anymore the same result than with two other online generators. If I encode a05ba7ba-ec61-11cf-8000-010157aa0 in ASCII the result was 1010101010101010101010 1101110111010010000001 1000111110010011101000 ... the other two return 1010101010101010101010 1100111001010010000001 1000000100010011111100 ... 1 is a black quare and 0 a white one Nice Toolkit!

the other two return

I count on it that you'll help me verify the implementation. Preparing 2.0 takes much longer than anticipated but I should have something in 24 hours.

I'd really like to be able to use them -- any update on when version 2.0 will be released? Keep up the good work!
