K4RL generates scannable digital passports for garments and products. One QR code — full origin trail, ownership history, EU DPP compliant.
Add your product to K4RL with name, materials, and supply chain details. Each item gets a unique ID.
K4RL issues a digital passport and generates a QR code. Attach it to the physical product — label, hang tag, NFC, anything.
Anyone with a smartphone scans the QR. They see the full origin trail — fiber to shelf — with verified ownership history.
The EU Digital Product Passport regulation is coming for textiles. K4RL structures all data to the spec — so you're compliant before the deadline, not scrambling after it.
Record every hop — fiber, spinning, dyeing, manufacturing, retail. Immutable, timestamped, human-readable.
Owners claim products via QR. Transfers are logged. Resale markets can verify authenticity instantly.
Push products, generate passports, query ownership — all via REST. Fits into any existing system.
