NTAG® 424 DNA / 424 DNA TagTamper – Advanced Security and Privacy for Trusted IoT Applications

NTAG424DNA

NTAG 424 DNA sets a new standard in secure NFC and IoT applications. The new chip generation offers state-of-the-art features for security and privacy protection, on attack-resistant certified silicon. The NTAG 424 DNA is architected to provide AES-128 cryptographic operation, new SUN authentication mechanism upon each read-out by an NFC enabled mobile device, as well as sensitive data protection with crypto-secure access permissions. This enables advanced product and content protection, plus secured and unique user experiences served in real-time.

The NTAG 424 DNA TagTamper tags go further and facilitate even more customized engagements by serving up status-aware, relevant consumer messages once the tag’s seal on a label or container has been broken.

Both the NTAG 424 DNA and 424 DNA TagTamper are sampling now with select customers.

Detailed documentation and support tools available upon request.
