NTAG 424 DNA / NTAG 424 DNA TagTamper

NTAG 424 DNA / NTAG 424 DNA TagTamper

A Powerful Mix of Security, Privacy & Trust for NFC in today’s IoT

NTAG 424 DNA sets a new standard in secure NFC and IoT applications. The chip platform 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, the 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, as they detect product opening and can support status-aware messaging, once the tag’s seal or label has been broken and tapped with an NFC phone.
