Engineering Brief
The NTAG 424 DNA TagTamper is an advanced NFC tag IC that extends the NTAG 424 DNA family with integrated tamper-loop detection capability. It features AES-128 encrypted Secure Unique NFC (SUN) message authentication, allowing each tap to generate unique encrypted URLs for server-side verification without requiring the tag to be online. The tamper-loop function monitors an external conductive connection and flags irreversible tamper status when the loop is broken, making it ideal for security seals on pharmaceutical packaging, premium products, and supply chain applications requiring evidence of first-opening or package integrity.
Typical Applications
- Brand protection and anti-counterfeiting
- Product authentication with tamper detection
- Pharmaceutical and medical device packaging security
- Smart labels with seal integrity verification
- High-value consumer goods authentication
- Supply chain tracking with tamper evidence
