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.
A buyer taps the NFC tag with a compatible phone and opens the link. The encoded route sends the first request to BrandGuard™ or to your website domain. With your domain as the destination, your backend submits the reading for verification. No dedicated app is 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.
Buyers can view the result on BrandGuard™ or, after successful verification, continue to the configured webpage. With the website-first API option, your backend receives the result from BrandGuard™ before your page displays it.
