tl;dr: TurnGoods tracks Entrupy authentication results against every luxury item in your inventory — bring your own Entrupy API key or log results manually. Authenticated items sell faster and at higher prices, with a verifiable digital certificate for buyers.

The Authentication Problem in Luxury Resale

The global counterfeit market is worth over $500 billion annually. In luxury resale, the stakes are even higher — a single fake item can destroy your reputation and expose you to legal liability.

How Entrupy Authentication Works

1. Photograph the Item

Use the Entrupy app or TurnGoods to take photos of key areas: hardware, stitching, leather grain, serial numbers, and logos. The app guides you through each shot.

2. AI Analyses Microscopic Details

Entrupy's AI examines details invisible to the human eye — leather pore patterns, thread spacing, hardware composition, and print alignment across millions of reference images.

3. Result in Minutes

You receive an authentication result: Authentic or Unable to Authenticate. Authentic items get a verifiable digital certificate with a unique ID and NFC tag option.

4. Certificate Attached to Listing

TurnGoods automatically attaches the Entrupy certificate to your listing. Buyers see the authentication badge and can verify the certificate online via a unique URL.
