Get a Quote
Custom NFC Tamper-Proof Authentication Tags use the NXP NTAG 424 DNA TagTamper chip to combine secure product authentication with tamper detection.
Ideal for premium products, packaging and brand protection, the tag can detect when its tamper loop has been broken while allowing customers or inspectors to verify authenticity with a compatible NFC smartphone.

- ✔ AES-128 secure authentication
- ✔ Tamper-loop detection for opened or broken seals
- ✔ Custom printed artwork, branding, QR codes and serial data
- ✔ Suitable for anti-counterfeit and premium product protection
Custom NFC Tamper-Proof Authentication Tags
Our NFC tamper-proof authentication tags are designed for brands that need more than a standard NFC sticker.
Using the NXP NTAG 424 DNA TagTamper chip, each tag can provide secure NFC authentication while also detecting whether a tamper loop or product seal has been broken.
When a customer, retailer or inspector taps the tag with a compatible NFC smartphone, the system can verify the NFC tag and deliver product-specific digital content or authentication results.
If the tamper loop has been broken, the tag can also report the changed seal status.
Secure product authentication
NTAG 424 DNA uses AES-128 cryptography and Secure Unique NFC (SUN) message authentication to support secure product and tag authentication.
Dynamic authentication data can be generated during each NFC interaction, providing much stronger protection than a simple static URL or UID-based NFC tag.
- AES-128 cryptographic security
- SUN message authentication
- Protected data access
- NXP originality features
- Secure NFC-enabled product verification
Tamper-loop detection
The NTAG 424 DNA TagTamper version includes a conductive tamper loop designed to detect whether a protected seal, label or package has been opened or broken.
The antenna or tamper-tail structure can be integrated across a closure, seal or opening point. Once the tamper loop is broken, the chip can provide status information indicating that the product has previously been opened or tampered with.
This allows the same NFC tag to support both authentication and product integrity verification.
