Nowadays, the authenticity of the RFID tags cannot be assured in the supply chain since these can be easily duplicated in the public space. We propose a novel Product Ownership Management System (POMS) of products for anti-counterfeits that can be used in the post supply chain by using the QR code. With the projected POMS, a consumer can reject the buying of counterfeits by scanning a QR code, if the seller does not have their proprietorship. This paper gives an application of the system that will help to overcome the problems related with the presently functioning supply chain management system and runs the mechanism to show the ownership of the products.
