Regarding genoco - there is no semacode technology at all it is bullshit. Simple, even not modified somehow Datamatrix. Readable by any modern reader. Nothing special. They try to use URL inside - futureless way. There a lot of such "products" - ShotCode, flashcode.fr, denimcode, Augme.... they try to get a peace of cake after dinner of big boys:) Therefore we decided do not do the same fail.
