Hi
i have been looking for a long time to get a free sdk to read 2d datamatrix barcode for iPhone, i was successful in getting sdks for QR Code and all other 1D codes.
I tried using ZXing (but this reads only QR codes) :
also Big in japan's http://www.freebarcodescanner.com/ , but this is not able to read Datamatrix.
ZBar which also does not read Datamatrix (Suggested by mprudhom)
Please help me out in finding a suitable library and if i found any will post here
Thanks Naveen
