I'm looking to program an data matrix encoder/reader for a project im currently working on, if you dont know what a data matrix is check here: http://en.wikipedia.org/wiki/Datamatrix The problem is I cant find any algorithms that describe how the data is encoded, The closest I've got is to finding the iso standard, but you have to pay to get access to that. See here: http://www.iso.org/iso/en/CombinedQueryResult.CombinedQueryResult?queryString=data+matrix If I was to pay for the standard documentation what would I be receiving? Also if anyone possibly knows any better 2d barcodes that are more widely documented around the net I'd love to know :)
