bigs, on Semacode,
you guessed right, it has been discussed;
a couple of highlights; 1, it (a semacode) is a special code that has to be applied to the item, versus using the existing barcode which is on every product now,
and 2, once the "link" is embedded on the product via the semacode, it can never be changed. So, it isn't flexible, and can't be updated. (as opposed to being able to update what is embedded on the product as you can using NEOM IP as the barcode stored info could be updated whenever the client wishes..or with other NEOM IP, rfid, voice, etc)
(oh, 3, semacode has no patents either.)

Also, there is something about it not being applicable for commercial use..will have to dig that detail up again as I don't recall the specifics off the top of my head.
