Frequently Asked Questions

What is the NTAG 424 DNA memory capacity?

The NTAG 424 DNA provides 416 bytes of user-configurable memory with file-based access control, operating as an NFC Forum Type 4 Tag.

What security features does the NTAG 424 DNA have?

The NTAG 424 DNA features AES-128 encryption, Secure Unique NFC (SUN) message authentication that generates unique encrypted messages per tap, originality signature verification, encrypted file access, and mutual authentication for advanced anti-counterfeiting protection.

What is SUN message authentication on NTAG 424 DNA?

Secure Unique NFC (SUN) enables the NTAG 424 DNA to generate a unique cryptographically secured URL or message with each NFC tap, allowing privacy-preserving authentication without exposing static credentials. This is ideal for brand protection and secure consumer engagement.

Is NTAG 424 DNA compatible with standard NFC phones?

Yes, the NTAG 424 DNA operates at 13.56 MHz following ISO/IEC 14443-A and NFC Forum Type 4 Tag standards, ensuring compatibility with all standard NFC-enabled smartphones without requiring special apps.

What is the difference between NTAG 424 DNA and basic NTAG chips?

Unlike basic NTAG chips (210μ, 213, 215, 216), the NTAG 424 DNA adds AES-128 cryptographic authentication, tap-triggered SUN secure messaging, originality signatures, and encrypted file access for advanced security applications like anti-counterfeiting and brand protection.

What applications is the NTAG 424 DNA designed for?

The NTAG 424 DNA is designed for brand protection, anti-counterfeiting, secure product authentication, pharmaceutical verification, luxury goods authentication, and secure consumer engagement where cryptographic security and standard NFC phone compatibility are both required.
