Why NTAG 424 DNA cannot be cloned
A standard NTAG213/215/216 carries a static URL that is easy to copy. NTAG 424 DNA generates a fresh AES-128-signed URL with a tap counter on every read (SUN message). Your server verifies the signature, so a copied link fails.
The chip also supports application keys, access rights and, in the TagTamper version, tamper-loop detection for opened packaging.
Applications
Authentication for luxury goods, wine, cosmetics and pharmaceuticals; uncopyable VIP membership and residence cards; event tickets; secure digital guest directories in hotels.
For hotels, NTAG 424 DNA can be combined with the door-opening MIFARE/DESFire chip in a single dual-chip card.
Body options and encoding
Wooden cards, rPVC and PVC cards, paper cards, adhesive NFC tags and tamper-evident tags. Before delivery we handle key provisioning, SUN URL templates and locking according to your verification backend.
Frequently asked questions
+What is the difference between NTAG 424 DNA and NTAG213?
NTAG213 stores a static link that can be copied. NTAG 424 DNA signs a new code with AES-128 on every tap, enabling uncopyable authentication.
+Does verification need an app?
No. Any NFC phone opens the signed link in the browser; verification happens on your server.
+Can it be combined with a hotel key card?
Yes. MIFARE or DESFire for the door lock and NTAG 424 DNA for guest services can share one dual-chip card.
