Why manufacturers not willing to allow the consumers to identify counterfeit/fake products?

We developed a perfect anti-counterfeit system that will allow the consumer to check if the products they purchased are original. When not original our office will contact them in a few minutes and collect purchase information and in most of the cases we replace the fake one with an original one at no cost to the consumer. But presenting the system to many popular brands they are not willing to accept the system in spite of their comments in public about how careful they are to protect their consumers. So far none of the manufacturer has pointed out a defect in the system we offered. What could be the reason behind rejecting our system that is based on http://www.isoriginalproduct.com ?
