NTAG 22x DNA

NTAG 22x DNA is an NFC Forum Type 2 tag IC family with integrated AES-128 Secure Unique NFC (SUN) authentication that generates cryptographically secure dynamic URLs or data on each tap. This dynamic authentication makes cloning and counterfeiting extremely difficult compared to static NFC tags.

NTAG 223 DNA offers 144 bytes of user memory (168 bytes total), while NTAG 224 DNA provides 416 bytes of user memory (540 bytes total). Both share the same AES-128 SUN authentication, originality signature, and brand protection features.

Yes, NTAG 22x DNA includes 32-bit password protection in addition to AES-128 authentication, originality signature verification, and a 7-byte UID for multi-layer security in brand protection applications.

AES-128 Secure Unique NFC (SUN) authentication uses cryptographic keys to generate dynamic, encrypted data or URLs each time the tag is scanned. This creates unique responses per tap, enabling secure authentication without requiring backend connectivity at the point of scan.

Yes, as an NFC Forum Type 2 compliant tag operating on ISO/IEC 14443-A at 13.56 MHz, NTAG 22x DNA is readable by all NFC-enabled smartphones that support the NFC Forum Type 2 standard.

The integrated read counter increments with each RF read operation, providing tamper evidence and enabling use cases like warranty validation, proof of authenticity checks, and tracking consumer engagement history.
