With the new NTAG 424 DNA brands can now effectively fight counterfeit and grey market activities at a cost level that allows mass market deployment of advanced NFC tags. By securely connecting goods to the IoT with multi-layered security including privacy protection features, brands for the first time can also combat data fraud such as IP theft, tampering and data breaches.

In addition, manufacturers benefit from delivering a secured and truly personalized mobile user experience that attracts, entertains and retains customers.

"As the number of connected objects is expected to reach 40 billion by 2022, there is a growing trend of organizations seeking more secure and feature-rich connectivity solutions,” said Phil Sealy, Principal Analyst at ABI Research. “Solutions such as NXP’s will be critical in providing enhanced digital services and customer experiences, while securely protecting products against counterfeits, channel diversions or other types of fraud.”

Secure and Trusted IoT Experience from the Tag-Edge to the Cloud

NTAG 424 DNA security features include:

Standards-based AES-128 encryption for authentication/secure messaging, or an alternative LRP-wrapped AES protocol for even higher attack resistance.
Secure Unique NFC (SUN) message authentication for advanced tag and data protection, useable with Android and iOS mobile devices.
On-chip secure data storage, accessible with 3-pass mutual authentication and encrypted data transfer.
Privacy-protected user data via Random ID and encrypted UID/data to enable compliance with latest data privacy regulations.
Attack-resistant hardware design to avoid data breaches and cloning.
Optional tamper protection with the NTAG 424 DNA TagTamper to securely detect if the tag seal remains intact for product integrity.
