SOLUTION · Condition & compliance

A serial you can defend.

Serialisation and chain of custody — a serial you can defend in audit. Time, place, actor written to the system of record, not stranded in a vendor app.

Where programmes stall

Serialisation fails when custody events are optional in the operating rhythm.

Event completeness

DSCSA/EU FMD-style chains break on missing ship/receive events, not on printer quality. Supervised scans and exception queues beat heroic catch-up.

Partner onboarding

Trading partners with weak edge processes will dump exceptions onto you. Contract the scan SLA and test it with real ASN volumes.

Offline sites

Plants and depots without reliable WAN need store-and-forward that still preserves sequence integrity — otherwise you invent custody gaps.

How it works

Serialisation & chain of custody: how it works, and what it proves.

The right radio for the job — chosen, never sold — mapped to your use case. That is what makes the ROI fast.

1 · Serialise

Each part or lot gets a unique, verifiable identity (GS1 / EPC).

2 · Hand off

Every custody transfer is read and time-stamped into a tamper-evident record.

3 · Prove

Full provenance and an unbroken custody chain are available on demand for audit or recall.

Diversion

Passive RFID → custody reads · GS1 / EPC → identity

Vendor-neutral

Which technology actually fits.

Paid only by you. Hardware stays on the vendor’s paper.

Passive RFID

Item/lot serialisation.

UWB

Secure-cell tracking.

Integration

Genealogy & audit.

In practice

Provenance you can prove on demand.

A manufacturer gives each part a verifiable identity and reads every custody hand-off into a tamper-evident record. Full provenance and an unbroken chain are available instantly for audit or a precise recall.

Typically bought by: Quality / compliance, supply chain, security, regulatory affairs.

USE CASES

Where this solution wins — examples by sector.

DSCSA pharma serialisation (pharma)

Every prescription unit serialised and aggregated.

EU FMD verification (pharma)

Falsified-medicines directive verification at dispense.

Aerospace SUP prevention (aerospace)

Suspect-unapproved-parts prevention through CoC.

Defence parts CoC (defence)

Defence supply-chain parts CoC.

Automotive safety-critical parts (automotive)

Safety-critical part serialisation for recalls.

Who needs this kind of programme.

Pharma, medtech and high-value electronics under DSCSA/EU FMD-class serialisation and custody expectations.

Defence and aerospace programmes needing auditable chain of custody across depots and contractors.

3PLs handling regulated goods who must prove who held what, when, without paper workarounds.

What buyers compare in this market.

Serialisation platforms (TraceLink / rfxcel / SAP ATTP-class) own the regulatory event exchange; RAIN RFID vendors (Impinj, Zebra, Avery Dennison, NXP silicon, Mojix-class) own fast physical verification. Cold-chain monitors (Sensitech / Controlant-class) are adjacent when custody includes temperature. Buyers fail when they treat RFID as a substitute for EPCIS/serialisation — or serialisation software as a substitute for physical read points.

Why custody programmes stall.

Software without portals. Perfect serial numbers that never get read in the real world create compliance theatre.

Custody breaks at partners. If 3PL and returns flows are out of scope, the chain is fiction.

Exception handling ignored. Aggregation breaks and damaged tags need owned playbooks on day one.

Independent. Vendor-neutral.

We do not sell serialisation licences or RFID hardware. We advise how physical identity events should feed the regulatory stack you already own — and where a cheaper barcode step is still the right control.

FAQ

Frequently asked questions

What does serialisation and chain of custody provide?

A unique identity for each item and an unbroken, time-stamped record of who held it and where - essential for evidence, controlled goods, pharma and high-value or sensitive items.

How is custody proven, not just claimed?

Each handoff is captured automatically by RFID or RTLS and logged immutably, so the chain is evidence-grade rather than reliant on manual sign-off.

Does it support DSCSA, GS1 or regulatory needs?

Yes - it aligns with serialisation standards such as GS1 and regulations such as DSCSA, producing the auditable records regulators and courts expect.

How does it integrate with our systems?

Serial and custody events flow into your ERP, QMS or evidence systems via API, so the record is centralised and queryable.

Where is this most valuable?

Pharma, defence, aerospace, law enforcement and any high-value supply chain where proving exactly what happened to each item is non-negotiable.
