Physical protection, engineered around your product.
We design and manufacture the NFC tag based on the unique structure, surface, and opening method of your product.
02 / 05UNIQUE SECURE IDENTITY
A unique cryptographic identity is securely encoded into the NFC tag.
The tag is configured with an individual cryptographic credential and activated for verification, establishing the secure identity used in every subsequent tap.
03 / 05FRESH CRYPTOGRAPHIC EVIDENCE
Every tap creates fresh cryptographic evidence.
To check a product's authenticity, a customer holds their phone near the NFC tag. The tag generates fresh cryptographic evidence, which the browser sends to BrandGuard™ for verification. No app required.
04 / 05SERVER-SIDE VERIFICATION
BrandGuard™ verifies the evidence behind every trusted result.
The evidence reaches the BrandGuard™ backend for verification. The service checks the dynamic authentication message, read counter and secure identity relationship. Supported tags are also evaluated for seal state.
05 / 05VERIFIED RESULT
The verified result returns to your customer's phone.
BrandGuard™ returns the current verification result to the customer's phone. When the evidence is accepted and a destination is configured, the customer can continue to a brand-approved experience.
