NTAG 424 DNA provides updated multi-level information security. The new chip for cards, bracelets, key fobs and tags NTAG424 DNA increases the security standard of NFC tags thanks to AES-128 encryption and generation of SUN (Secure Unique NFC) messages.
Each time the RFID chip interacts with the reader, it generates a new unique security code, which eliminates counterfeiting. Designed specifically for NFC and IoT channels, the NTAG 424 DNA tag is suitable for chipping clothing, food, beverages, pharmaceuticals, electronics, etc.
The DNA NTAG 424 chip sets a new standard in NFC and secure DNA applications. The new generation of NTAG chips offers the latest security and privacy protection features. To achieve this, the chip is made of attack-resistant certified silicon. The NTAG 424 DNA chip is designed to support operations protected by AES-128 encryption, including the new SUN (Secure Unique NFC Messages) authentication mechanism, as well as the protection of sensitive data with encrypted access permissions. These features provide advanced product and content protection, as well as a secure and unique user experience in real time.

The DNA NTAG 424 chip sets a new standard in NFC and secure DNA applications. The new generation of NTAG chips offers the latest security and privacy protection features. To achieve this, the chip is made of attack-resistant certified silicon.

These features provide advanced product and content protection, as well as a secure and unique user experience in real time.
What is SUN message?
The Secure Unique NFC feature generates a unique and secure authentication code every time a card, bracelet, key fob or other tag is swiped. With the SUN feature, an NDEF message is generated (readable by any NFC smartphone) using an encryption algorithm that includes: URL, UID, counter scan and AES key. Being also connected to the counter scan, each time the chip is read, it generates a new string. Thus, the content is protected from cloning. It is interesting to note that this security enhancement is also a simplification of the approach for the end user, who does not need to download any specific application to verify the authenticity of the tag (and the content associated with it).How to order DNA NTAG 424 cards, bracelets, keychains and stickers?
