How to Authenticate Drugs and Medical Devices When the Packaging Can Be Copied

The problem

Counterfeit and substandard drugs and medical devices reach patients through supply chains that are already regulated and already serialized. The controls exist; the problem persists, because the identifier and the product are separate things.

Reprocessed and repackaged medical devices are a documented source of counterfeit and substandard products. A device that has been repackaged carries whatever identity the repackager applied to it.

Why barcodes and serialization alone leave a gap

DSCSA and FDA UDI requirements mandate identification and traceability, and they work as designed. What they identify is a package, a model and a lot.

• A barcode identifies the package it is printed on, not the product inside it.
• UDI identifies the model and lot, not the individual unit in hand.
• A copied label on a counterfeit scans exactly like a genuine one.
• Nothing in the scan confirms the physical item is the one that was manufactured.

A better approach: authenticate the item, not its label

FeaturePrint assigns each drug package or device a permanent photographic identity at manufacture, taken from its own surface. It is verifiable at every downstream supply chain node from a standard camera, with no barcodes or RFID required.

Because the identity is physical, a counterfeit fails even with a perfect copy of the genuine label. FeaturePrint reports zero false positives, meaning every authentication failure is a confirmed counterfeit or unauthorized substitution rather than a system error.

Implants and the sterile field

Implantable devices — hip replacements, cardiac devices, spine implants — are among the highest-consequence items in healthcare, and the last point at which a problem can still be caught is before implantation.

FeaturePrint verifies each implant from a photograph before it is implanted, confirming it is genuine and carries the correct service and sterilization history. The same check applies to devices entering the sterile field, authenticating at the individual item level rather than the lot.

One authentication layer across regulatory regimes

FeaturePrint supports DSCSA in the United States, the EU Falsified Medicines Directive, FDA UDI requirements for medical devices, and related pharmaceutical and device traceability regulations. Rather than a separate system per jurisdiction, the same enrolled physical identity serves each of them.

How it works in three steps

1. Photograph each package or device at manufacture to enroll it.
2. FeaturePrint stores its surface signature. Nothing is added to the product or its packaging.
3. Photograph it again at any downstream node — distribution, hospital receiving, or the point of care — to confirm it is the genuine enrolled item.
