How NFC Tags Like NTAG X DNA Enhance Product Anti-Counterfeiting

Counterfeiting remains a major challenge for brands across industries, from luxury goods to pharmaceuticals. To combat this, NFC (Near Field Communication) technology has emerged as a powerful anti-counterfeiting solution. With the release of NXP’s NTAG X DNA in May 2025—featuring 16KB storage, 848 kbps high-speed data transfer, and SUN (Secure Unique NFC) authentication—businesses now have an even more secure way to protect their products.

At UNIRFID, we provide NTAG 424 DNA tags and cards to help companies implement tamper-proof, cryptographically secure NFC solutions. This article explores how NFC-based anti-counterfeiting works and why NTAG X DNA and NTAG 424 DNA are game-changers.

How NFC Anti-Counterfeiting Works

NFC tags store unique, encrypted data that can be verified via a simple smartphone tap. Here’s how they help prevent fraud:

1. Secure Authentication with PKI & SUN Technology

• The NTAG X DNA supports asymmetric encryption (PKI) and SUN authentication, ensuring only genuine tags can be verified.

• Each tag has a unique digital signature, making duplication nearly impossible.

2. Digital Product Passport for Full Traceability

• NFC tags can store a "Digital Passport" containing:

  • Manufacturing details (date, location)

  • Supply chain data (shipment logs, authenticity checks)

  • Consumer verification history

• Consumers simply tap their phone to confirm product legitimacy.

3. High-Speed, High-Capacity Data Storage

• With 16KB memory and 848 kbps transfer speeds, NTAG X DNA allows for:

  • Rich product info (ingredients, manuals, promotions)

  • Secure firmware updates for IoT-connected devices

Why Choose NTAG 424 DNA & NTAG X DNA?

Both tags offer tamper-proof security, but NTAG X DNA is ideal for high-value products needing extended data storage and ultra-fast NFC interactions.
