How authentication works in practice

What is actually being compared?

A new capture of the physical O-KEY is compared with the registered reference for that item. The decision is not based only on reading a valid identifier.

What should happen after a result?

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

Who owns the operating policy?

Usually the team responsible for product risk, quality, safety or protection, with operations and IT where needed. We help define roles, operating conditions and follow-up.

How are security and usability validated?

Authentication settings are validated for the product, device, environment, user and required security level before wider deployment.
