Product Authenticity Evidence Check
Design a mobile flow that helps secondhand shoppers inspect authenticity signals without promising a definitive verdict.
The brief
Understand the problem
Background
Counterfeit goods are difficult to identify from appearance alone. A useful tool can organize serial records, seller documents, construction details, and known warning signs, but it must communicate uncertainty and avoid presenting weak evidence as proof.
User context
Mina is considering a used designer handbag from an independent seller. She wants to document the evidence before paying and understand what would require a specialist inspection.
Product problem
Shoppers need a clear way to gather and interpret authenticity signals while preserving uncertainty, seller privacy, and a path to expert review.
Objective
Design an evidence collection and review journey that supports a careful purchase decision rather than issuing a guaranteed authentic or fake label.
