Frequently Asked Questions
What security features does the NTAG 426Q have?
The NTAG 426Q includes AES-128 mutual authentication, Secure Unique NFC (SUN) message generation with encrypted CMAC, tamper detection capabilities, originality signature for chip authentication, and 32-bit password protection for comprehensive anti-counterfeiting security.
How much memory does the NTAG 426Q have?
The NTAG 426Q has 416 bytes of user-configurable memory and 1024 bytes total EEPROM capacity.
What is SUN message generation on the NTAG 426Q?
SUN (Secure Unique NFC) message generation creates encrypted, per-read unique URLs or data that change with each tap, preventing replay attacks and tag cloning. This enables secure authentication without requiring a constant internet connection at the point of scan.
Is the NTAG 426Q compatible with standard NFC phones?
Yes, the NTAG 426Q operates at 13.56 MHz with ISO/IEC 14443-A compliance and is NFC Forum Type 2 compliant, making it readable by standard NFC-enabled smartphones without requiring special apps for basic tap-and-verify functionality.
What applications is the NTAG 426Q designed for?
The NTAG 426Q is specifically designed for anti-counterfeiting applications in pharmaceutical products, luxury goods authentication, secure supply chain tracking, and high-security brand protection systems where cryptographic authentication is required.
Can the NTAG 426Q detect if a product has been tampered with?
Yes, the NTAG 426Q includes built-in tamper detection capabilities that can detect physical tampering attempts, making it suitable for applications requiring evidence of packaging integrity in pharmaceutical and luxury goods sectors.
