A public code can be copied using many different techniques. Unscrupulous businesses and individuals can take the public qrcode and attach it to a counterfiet product. Our System uses a two code verification system. The second code is a private code that is hidden within the product. If the hidden qrcode is not found or if you scan the hidden private code and it is not found in our database then it is almost certain that the product is not manufactured from the company as stated and is not genuine.
