QR Codes for Supply Chain Visibility: From Supplier to Shelf

1. The Traceability Gap

Most supply chains involve multiple parties in different countries using different systems. A single scan event at each hand-off creates a shared trail without requiring system integration between all parties.

2. Scan-at-Handoff Model

Each party scans the shipment QR when receiving and again when dispatching. The scan event is posted to a shared visibility platform (or a simple webhook). Timestamps, GPS, and actor identity are recorded.

3. Payload Design

Encode a shipment ID in the QR, not the full product data. The ID is the key to look up the record in the visibility system. This keeps the QR small and the data model flexible.

4. Consumer-Facing Transparency

The same QR that travels the supply chain can be the consumer-facing code on the finished product. Consumers scan and see: origin, journey milestones, certifications, and carbon estimates.

5. Standards

GS1 Serial Shipping Container Code (SSCC) and GS1 Digital Link are well-adopted frameworks for shipper and item-level QR codes in supply chains.
