Why this exists

A verified passport sells
faster and for more.

Buyers on Vestiaire, Vinted, and Chrono24 pay a premium for documented items. A NAK3D passport tells the buyer exactly what they're getting — condition assessed, serial confirmed, ownership recorded, 3D model included. No negotiation. No doubt.

"Buyers on Vestiaire consistently pay 15–30% more for items with independent condition documentation. A seller who can prove what they're selling commands the price they ask."
Why resale sellers use NAK3D LOCK

And when the EU DPP regulation requires provenance documentation for luxury goods from 2027 — your passport already exists, already timestamped, already permanent.

For businesses

Reseller, broker,
or small brand?
Let's talk.

The CHF 89 consumer pack is built for individual owners. If you're listing multiple items regularly on Vestiaire, Chrono24, or running a vintage or pre-owned business — you need volume pricing, batch processing, and potentially a white-label option.

Our enterprise pipeline — NAK3D DISCO — is built exactly for that. Let's talk about what makes sense for your volume.

EU compliance

The regulation
is coming.

By 2027, luxury goods sold in the EU require a Digital Product Passport. Most people think this only affects manufacturers. It doesn't — secondhand items without a DPP will be harder to resell, insure, and authenticate.

Individual owners can create their own — today. A passport created now carries a permanent timestamp. The regulation arrives. Your record already exists.
