Consumer
Materials, repair, recycling, origin and environmental information.
Identity layer
One product. One identity. Multiple contexts.
producto.id/X7F9-AB2 is the stable link on a QR, NFC tag or label. The identifier remains; representations change for consumers, professionals, auditors and machines.
Not a URL shortener
Resolution with authorization, not User-Agent tricks
Public consumer data may be open. Sensitive views require real authentication. A photographed QR can be scanned a million times — the architecture assumes that.
Professional
Technical docs, manuals, spare parts and maintenance — after auth.
Auditor
Evidence, certificates, suppliers, declarations and change history.
API
