SAG believes that in today’s hyper-connected world, every product tells a story - and that story must be authentic, secure, and trusted. From medical devices safeguarding patient health to luxury goods preserving brand integrity, NFC technology serves as the invisible handshake between products and people. As devices become smarter and regulatory demands intensify, security and compliance stand as the cornerstones of genuine innovation.
NXP’s latest breakthrough, NTAG X DNA, sets a new benchmark in secure NFC and IoT integration by protecting data, ensuring interoperability, and preparing products for the future. With decades of experience deploying RFID solutions across diverse industries, SAG recognizes the growing need for stronger security and real-time traceability. As an NXP Gold Partner with a proven track record in designing and scaling temperature-tracking solutions, SAG was chosen by NXP to debut NTAG X DNA. Together, they delivered the first working sample kit—transforming next-generation security into practical, real-world solutions.
A Game Changer: NTAG X DNA
As one of the most advanced NFC ICs available, NTAG X DNA represents a major step forward in integrated security, compliance readiness, and IoT connectivity. This next-generation chip delivers unclonable authentication, privacy protection, and seamless data exchange across industries, helping brands respond to rising demands for stronger protection, regulatory alignment, and smarter connected products.
Key Innovations That Set NTAG X DNA Apart
1. Higher Security by Design: Certified to CC EAL6+, NTAG X DNA provides AES-256 encryption, ECC (Elliptic Curve Cryptography) for asymmetric authentication, and SUN authentication, while remaining fully functional even when the host device is powered off. It ensures trusted authentication, secure offline data access, and regulatory readiness in mission-critical environments.
2. Dual Interface for Seamless IoT Integration: By combining NFC for external communication with I²C for internal data exchange, NTAG X DNA bridges physical products with their built-in electronics. This dual-interface design enables real-time usage tracking, secure pairing, and on-device logging, even for products without built-in connectivity.
3. Battery-Free Operation: Harvesting up to 20 mW from an NFC reader, NTAG X DNA can power MCUs without a battery. This creates sustainable and maintenance-free solutions that enable secure offline data access, supports long-term reusability without battery replacement, and ensures compliance with sustainability goals.
4. Silent Mode for Privacy Control: Configurable Silent Mode allows tags to temporarily or permanently deactivate NFC responses after a successful read. This ensures privacy, prevents redundant reads in multi-tag settings, and maintains compatibility with legacy readers.
Building Trust Through Global Standards
As global regulations evolve, NTAG X DNA keeps you ahead. The EU Digital Product Passport (DPP) and Ecodesign for Sustainable Products Regulation are driving transparency, traceability, and sustainability. The EU Cyber Resilience Act (CRA) raises the bar for connected device security, while the FDA’s Cybersecurity Guidance in the U.S. emphasizes secure design, threat protection, and data integrity across the lifecycle of medical devices.
Whether in healthcare, pharmaceuticals, luxury goods, or automotive, NTAG X DNA provides a compliance-ready advantage, combining strong authentication, privacy protection, and secure connectivity. It’s not just about meeting today’s standards; it’s about preparing products for tomorrow’s challenges.
Shaping the Future, Together
At the core of NTAG X DNA lies a powerful innovation: the integration of NFC for external interaction with I²C for internal communication. What makes this breakthrough practical is SAG’s ability to design and optimize the system architecture, antenna design, and I²C integration that seamlessly connect these two interfaces. By combining our antenna expertise, RF engineering, and customization know-how, we turn the dual-interface power of NFC and I²C into real-world applications. This enables physical products, from medical tools to automotive parts, to securely connect their built-in electronics with external interactions, unlocking smarter, more connected applications.
Looking ahead, SAG is paving the way for next-generation products featuring real-time tracking and enhanced security powered by NTAG X DNA to meet the growing demands of intralogistics tracking for high-value, temperature-sensitive, and essential assets, safeguarding food safety and drug security, while supporting Digital Product Passport compliance and ensuring full chain of custody across the supply chain. Together with NXP, we are setting new benchmarks in security, privacy, and interoperability with NTAG X DNA.
