O-KEY securely connects each physical medicine or device to its identity, history, and authorised information helping manufacturers protect patients, resolve investigations faster, and maintain trusted chain of custody throughout the lifecycle.

Product authentication is broken. And it's costing you.

Most solutions manage data, not risk. O-KEY unites serialization and security in one legal proof so you can stop counterfeits, control your supply chain, and ensure compliance.

The O-KEY Tag: a physical identity that can be verified

Explore the O-KEY Tag
O-KEY physical identity label

Each O-KEY combines a unique identifier with a registered, high-resolution record of its physical pattern. Once applied and captured, it becomes the trusted link between the individual item, its product information and its history.

O-KEY can be introduced as a label, seal, surface application or embedded implementation. The format and registration workflow are chosen around the product, production process, durability and security requirement.

Apply the O-KEY. Capture its physical pattern. Register the reference and product record. Use that reference for future authentication.

Implementation built around your product

Explore Implementation
O-KEY implementation in production

We fit O-KEY to the product, production environment and existing systems with the least unnecessary change.

A focused pilot validates the physical format and placement, application and registration, authentication under representative conditions, the operating workflow and the minimum data or integration required.

Once proven, the same model can be standardised across more products, sites, suppliers and markets.

Authentication based on the physical identity

Explore Authentication
User authenticating an O-KEY with a smartphone

A valid identifier can be copied. O-KEY authentication compares a new capture of the physical O-KEY with the registered reference for that individual item.

The Authentication App guides an authorised user through capture. Computer-vision models evaluate the physical patterns, and the result can be recorded for follow-up in O-KEY Studio.

Authentic confirms that the captured O-KEY matched its registered reference. Not matched means the comparison failed and should trigger the organisation's defined follow-up, not an automatic counterfeit conclusion.

One product. One identity you can verify.

Four aspects. One connected O-KEY system.

See how O-KEY works
How the connected O-KEY platform works

O-KEY gives each item a unique physical identity and connects authentication, trusted product information and lifecycle events to the same product.

Every implementation brings together four connected aspects: the O-KEY Tag creates the physical identity; the Product Portal delivers item-specific information and services; the Authentication App verifies the physical O-KEY; and O-KEY Studio manages identities, users, data, events and integrations.

The system is configured around the use case, while existing enterprise systems can remain authoritative where appropriate.

Product lifecycle activity connected to an O-KEY identity

Give every product a history

Connect manufacturing, distribution, authentication, service and ownership to the same physical identity.

Lifecycle Events connected to the physical item

Explore Lifecycle Events
Product lifecycle history connected to a physical identity

Identity tells you what the product is. Lifecycle Events show what happened to it.

Connect production, shipment, authentication, service, ownership, return and circularity events to the identity of the physical item—not just a SKU, batch or code.

Events can come from scans, O-KEY Studio, APIs, devices or existing enterprise systems, while those systems remain authoritative where appropriate.
