A Certified Quick Response Code (“CQR”) is associated with a trusted Product Certificate Authority (“PCA”), which in turn is associated with a unique top-level domain (“TLD”). A CQR affixed to a product may point to a URL comprising the unique TLD. A consumer may know by virtue of the association of the TLD with the PCA that the product is legitimate, while a product manufacturer can better monitor counterfeit goods by further associating each CQR with a universal unique identifier.
