FibreTrace

Remote · 2025

A product passport that proves where a garment's fibre actually came from.

Problem

Brands needed shoppers to scan a product, see its origin, and trust the result.

Approach

Native iOS app in SwiftUI
A QR / NFC scan opens a signed, tamper-proof passport
Works offline
On-device ML flags fake tags and broken chains of custody

Outcome

Scan to verified passport in under three seconds
Works with no connectivity — verification holds up in a warehouse or a paddock
Launched a pilot with a partner brand
