Okay, now I understand that. I know they're doing that with pharmaceuticals in the States, where they have to be tracked. So if a legitimate retailer says he'll buy only if you can show the steps to it.... But then again, documents are counterfeited; forgeries are put in place; false companies are set up. Things like that happen. So it would be a very complex thing to do.
