NXP Semiconductors has unveiled the NTAG X DNA, a new Type 4 secure connected NFC tag designed for product authentication and Digital Product Passport applications. Building on NXP’s established track record in secure authentication technology, including its EdgeLock security solutions, the NTAG X DNA features 16KB of memory and achieves data transfer speeds of 848 kbps while supporting both NFC and I2C communication interfaces.
The NTAG X DNA incorporates multiple interface options, including NFC, I2C, and GPIO, enabling dual interface functionality. The design allows direct MCU connection for device diagnostics while maintaining NFC capabilities for mobile device interaction. The tag operates according to ISO/IEC 14443-4 standards and features public key infrastructure-based asymmetric cryptography, backed by Common Criteria EAL 6+ security certification – one of the highest security certifications available for commercial electronic components.
The device integrates with NXP’s EdgeLock 2GO service, a cloud-based platform for secure credential management and deployment. The service manages both initial certificate provisioning and the generation of additional certificates as needed for specific implementations, building on NXP’s established expertise in secure identity solutions for IoT devices.
Target applications for the NTAG X DNA span multiple sectors, including healthcare devices, smart home systems, mobile and gaming accessories, and industrial equipment requiring authentication capabilities. The technology is particularly relevant for medical device authentication, where NFC technology is increasingly being adopted for verification and tracking purposes. The NTAG X DNA also supports upcoming European Union Digital Product Passport requirements, scheduled for implementation by 2027, which will require digital records containing product composition, origin, and lifecycle information as part of the EU’s broader circular economy initiatives.
NXP has released comprehensive technical documentation for the NTAG X DNA, including application note AN14513, which details the tag’s features, interfaces, potential applications, and protocols, including Global Platform T=1 over I²C + NFC (Type4Tag) + ECC Signature. The documentation supports developers in implementing secure authentication solutions that comply with emerging regulatory requirements while maintaining robust security standards.
