Engineering Brief
The NTAG 424 DNA is NXP's advanced secure NFC tag IC featuring AES-128 cryptographic authentication and Secure Unique NFC (SUN) message capability for tap-triggered secure URL generation. It provides 416 bytes of user-configurable memory with file-based access control and supports privacy-preserving authentication where each tap generates a unique encrypted message. The chip operates at 13.56 MHz following ISO/IEC 14443-A and NFC Forum Type 4 Tag standards, making it ideal for brand protection, anti-counterfeiting, and secure consumer engagement applications where both security and standard NFC phone compatibility are required.
Typical Applications
- Brand protection and anti-counterfeiting
- Secure product authentication
- Tamper-proof consumer engagement
- Supply chain integrity verification
- Pharmaceutical and luxury goods authentication
- Secure IoT device provisioning
