libdmtx is a shared library for Linux that can be used to read (scan & decode) and write (encode & print) 2D Data Matrix barcode symbols. It is released under the LGPL and can be used and distributed freely under these terms.
Mit bcTester können Barcodes gelesen werden, die in Bilddateien enthalten sind. Sowohl die herkömmlichen Strichcodes (lineare Barcodes) als auch die moderneren 2D (zweidimensionale) Barcodes können erkannt werden.
This is a small application that can be fed the output video stream of a webcam, in which it can recognise and decode code-39 barcodes. It is simply a console application that is limited to parsing an input raw ppm stream, outputting the barcodes to the stdout.
ZXing (pronounced "zebra crossing") is an open-source, multi-format 1D/2D barcode image processing library implemented in Java. Our focus is on using the built-in camera on mobile phones to photograph and decode barcodes on the device, without communicating with a server. We currently have support for:
* UPC-A and UPC-E
* EAN-8 and EAN-13
* Code 39
* Code 128
* QR Code
* ITF
* RSS-14 (Stacked and Limited)
* Data Matrix ('alpha' quality)
* PDF 417 ('alpha' quality)

I recently found this blog which shows a business card with a QR card. I thought I'd create a business card with LaTeX with a similar QR code. I took a LaTeX template from here, found out about the pst-barcode pacakge, learnt the MECARD format, and combined them to make this:
This shall be the place to find both usage documentation and in depth tech background for our open source DataMatrix ( 2d barcode) decoder.
It is a .net (C#) component, ready to use to decode DataMatrix from bitmaps, for example shot with a cheap webcam. It's licenced as open source under the GNU General Public Licence.
