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. 

Certified EdgeLock® Assurance

The NTAG 424 DNA and the NTAG 424 DNA TagTamper, part of the Certified EdgeLock Assurance program, are designed to meet industry standards and follows NXP's security-by-design approach. They have been certified by an independent lab.

Features

Typical Applications

NTAG 424 DNA is preferably applied to scenarios requiring high value, anti-counterfeiting, privacy sensitivity and dynamic authentication:

1. Luxury & high-end product anti-counterfeiting (luggage, apparel & footwear, red wine, artworks): Each tag is assigned a unique key. A dynamic SUN URL will be generated with one tap of a mobile phone, and authenticity verification is completed via backend server to prevent tag cloning.

2.Healthcare & medical applications (vaccine certificates, drug traceability, medical device identification): With EAL4 security certification, encrypted UID and random ID are adopted to protect privacy and prevent data tampering.

3.Supply chain traceability (electronics, auto parts, military industry): Key data is stored in the 128-byte secure storage area, and 3-pass mutual authentication is adopted to avoid unauthorized data access.

4. Digital content & membership rights benefits (fan exclusive privileges, electronic tickets, coupons): A uniquely signed URL is generated upon each NFC tap, preventing unauthorized use via screenshot or copy duplication.

The Market Is Demanding It — Right Now

Three powerful forces are converging to make NTAG 424 DNA-based authentication not just advantageous, but necessary:

  Regulatory Pressure: EU Digital Product Passport (effective 2026–2030 by category), US DSCSA pharmaceutical serialization, China NMPA track & trace — all require verifiable, serialized product identity. NTAG 424 DNA is architecturally aligned with every major regulatory framework.

  Consumer Expectation: Gen Z and millennial consumers actively research product authenticity. 73% say they would pay a premium for a product they can independently verify as genuine. NFC delivers this verification in the most frictionless way possible.

  Brand Imperative: The cost of one major counterfeiting scandal — in brand equity, legal fees, and customer loss — dwarfs the cost of deploying authentication at scale. Brands that authenticate proactively are not just protecting products; they are building a trust infrastructure that compounds in value over time.
