## What is O?

Verify product authenticity with a single scan. The O-KEY Authenticator lets you instantly confirm whether an O-KEY protected product is genuine. Every O-KEY contains a unique physical fingerprint that cannot be copied or replicated, giving brands, partners, and consumers confidence in the authenticity of every product.

Beyond authentication, an O-KEY can connect you to product-specific information such as documentation, ownership history, sustainability data, service records, installation guides, and other digital content defined by the product owner.
Whether you're protecting luxury goods, industrial equipment, automotive components, medical products, or consumer packaging, O-KEY makes trusted product verification simple.
