The Data Matrix barcode (ISO/IEC 16022) is a high-density, two-dimensional (2D) symbology that encodes text, numbers, files and actual data bytes. This FAQ provides information and answers to commonly asked questions about the 2D Data Matrix barcode symbology. Data Matrix Barcode Overview Data Matrix is a very efficient, two-dimensional (2D) barcode symbology that uses a small area of square modules with a unique perimeter pattern, which helps the barcode scanner determine cell locations and decode the symbol. Characters, numbers, text and actual bytes of data may be encoded, including Unicode characters and photos. The encoding and decoding process of Data Matrix is very complex.
Specific standards & specs for the 2D Data Matrix barcode symbology: Data Matrix Size and Accuracy Data Matrix is one of the smallest and most dependable barcode symbologies. Products for Printing & Generating Data Matrix Verifying Barcodes Generating GS1-DataMatrix Barcodes The encoding mode must be set to ASCII. Matrix Codes & Visual Code Recognition on Cellphones. As mentioned briefly before i’m currently doing some work in the area of visual code recognition, on cellphones to be more specific.
After some research i’m a little overwhelmed, lots of activity in this area and it seems that most people are happily working on their own funky standards/implementations/platforms (it’s often difficult to figure out what they’re actually doing behind all the marketing-speech) for quick & easy profit. Anyway, this is a list of 2d barcode standards and platforms which are used for applications on cellphones, with brief commentary and roughly in order of usefulness to me. This list is by no means complete, suggestions and corrections are more than welcome. I’ll update this list as i come across new stuff. QR Code (wikipedia) was developed by denso wave and released in 1994.
If you’ve made it this far i have good news for you: it’ll be a bit less technical and a bit more practical from here on. So that’s it for today, thanks if you’ve made it this far. Libdmtx Home. Semacode | URL barcodes | practical ubiquitous computing. Datamatrix Generator.
