NkwaTrace

Know where every pack of medicine has been.

A pharmaceutical traceability system for Ghana. Packs are serialised to GS1 standards, each change of custody is recorded, and batches of records are anchored to a blockchain so the trail can't be quietly rewritten.

What it does

One trail from factory to patient.

GS1 serialisation

Products, packs and shipping units carry GTIN, SGTIN and SSCC identifiers that any GS1-literate partner already understands.

Custody events

Every hand-off is captured as an EPCIS-shaped event: what moved, where, when and who took responsibility for it.

On-chain anchoring

Events are grouped into Merkle batches and their roots anchored on-chain, so any record can later be proven unchanged.

Public pack verification

Pharmacists and patients can check a pack's authenticity and history without signing up for anything.

Recall register

Recalled batches are flagged in one register, and every verification checks against it automatically.

Anomaly alerts

Unusual patterns in the custody trail are raised as alerts, so suspect packs are investigated rather than sold.

Who it's for

One console, three views.

Regulators

See the whole market's custody trail, issue recalls and follow up on anomaly alerts from one place.

Manufacturers

Commission serials, record shipments and prove that genuine stock left the factory intact.

Receive stock against its record and verify any pack at the counter before it reaches a patient.
