Methods and systems for product authenticity verification
InactiveUS20160321677A1Address limitationsCommerceSpecial data processing applicationsPurchasingComputer science
Consumer purchasing is increasingly being performed online and at the same time internationally so that consumers in one country can purchase directly other countries through online resources and have their purchases shipped directly. Accordingly, distributing counterfeit products becomes easier, especially if the consumer may never have seen, touched, tasted or experienced the original authentic product to recognise a counterfeit. In other instances, consumers know because they pay a fraction of the legitimate version's price. It would be beneficial to provide manufacturers with a means of labelling their products uniquely such that the consumer and / or retailer is able to verify the authenticity of the product quickly and automatically through a portable electronic device or point-of-sale terminal, for example. Further, it would be beneficial for the provisioning of such unique codes to support one-time use, traceability of authentic products and consumer registration to support subsequent sale of their authenticated product.
