Entrupy authentication works by using a handheld device and AI to analyze microscopic images of the bag and compare them to a vast database of known authentic and counterfeit products. The process involves capturing high-magnification images of materials, logos, and hardware, which are then analyzed by the machine learning algorithms to verify authenticity or return an "unverified" result. Authentic results are backed by a financial guarantee and so if ever a mistake is made (Entrupy claim 99.86% accuracy) then everyone is protected.

So each qualifying bag comes with an Entrupy certificate that includes a QR code which gives a “forever” guarantee - and we can always provide a backup if it gets misplaced. Details of the certificate will be in the listing of any relevant bag - or just ask for details.
