Wet inlay, round, with a diameter of 22 mm, with NXP NTAG424 DNA chip

The NTAG 424 DNA chip sets a new standard in NFC and secure IoT applications. The new chip generation offers state-of-the-art security and privacy protection features. For this purpose, the chip is made with attack-resistant certified silicon.

The NTAG 424 DNA chip is designed to support operations protected by AES-128 encryption, including a new SUN (Secure Unique NFC message) authentication mechanism, as well as the protection of sensitive data with encrypted access permissions. These features allow advanced product and content protection, as well as secure and unique user experiences in real time.

What is the SUN message

The Secure Unique NFC function generates a unique and secure authentication code whenever the Tag is read. With the SUN function, an NDEF message (readable by any NFC smarpthones) is generated, using an encryption algorithm that includes: URL, UID, counter scan, and AES key.

SUN message - NTAG DNA

Being also connected to the scan counter, each time the Tag is read, it generates a different string. In this way, the content is protected from cloning.

It is interesting to note that this increase in security is at the same time a simplification of the approach to the end user, which does not need to download any specific application to verify the authenticity of the Tag (and the content linked to it).

How to encode an NTAG 424 DNA

To enable the SUN message, we recommend using the Identiv uTrust 3700 F and TagXplorer software, developed by NXP.

Technical features

  • Available memory: 256 bytes (for NDEF message)
  • Adhesive dimensions: 22 mm (diameter)

  • Storage temperature: -55°C ÷ 125°C
  • Operating frequency: 13.56 MHz


  • Anti-counterfeiting
  • Secure login
  • Token generation
  • Product authenticity
  • Applications that handle sensitive data
