A lot of companies already do that. Depending on the type of product, they have certificates with the product. With software and things like that, they have to have certificates of authenticity, or COA, labels affixed. A lot of companies are doing this, so when they do come across, if it's handed over to the police, they contact the companies to verify that.
Once again, you're dealing with counterfeiters who are very sophisticated. If a legitimate manufacturer puts a power cord together and it costs them $5, the counterfeiter may only spend 50 cents. So they can spend a little more money falsifying or forging documents or certificates, and so on.
Once again, it's always about catch-up with the counterfeiters. The companies are always trying to change their technologies with certificates of authenticity and things like that. The counterfeiters are always doing the same thing.
