1 General description

NTAG 223 DNA is an innovative security IC solution, compliant with NFC Forum Type 2 with 144 bytes of user memory. The technology uses advanced protection to support a broad range of NFC-based applications that can be trusted to protect products, services, and IoT-driven user experiences. NTAG 223 DNA IC comes with a Secure Unique NFC (SUN) message authentication. The IC can automatically add its UID and incremental tap counter to the programmed NDEF (NFC Data Exchange Format) message through ASCII mirroring, and uses an AES-128 key to secure the message with a cryptographic message authentication code (CMAC). The SUN functionality supports advanced protection to verify a tag’s authenticity and integrity, whilst also enabling secured unique user experiences served in real time. The IC uses AES-128 cryptography and is Common Criteria EAL3+ (AVA.VAN.2) targeted. NTAG 223 DNA offers in addition an ECC-based originality signature to assure tag origin. The originality signature can be further customized and permanently locked during tag initialization.

3 Applications

? Advanced anti-counterfeiting protection

Reliably verify authenticity of physical goods, anytime, anywhere using an NFC enabled device. Also consider

automated authentication of NFC tagged consumables and parts in embedded devices.

? Improved supply chain visibility and control

Visibly help track products along the supply chain, and reduce grey market diversion and other fraud. Enable

more transparent and secure supply chains.

? Augmented user experiences

Use status awareness to prompt targeted messages, e.g. pre-/post-retail. Evolve the user experience by

engaging with greater personalization, e.g. with tap-unique content and exclusive loyalty rewards.
