FAQ
What is an NFC/RFID NTAG® 424 DNA card?
NFC/RFID NTAG® 424 DNA is a high-security NFC smart tag operating at 13.56 MHz (HF RFID), designed for advanced authentication, anti-counterfeiting, and secure IoT applications.

It is based on ISO/IEC 14443A and NFC Forum Type 4 standards and uses AES-128 cryptographic security.
What is NFC/RFID NTAG 424 DNA TagTamper?
NFC/RFID NTAG 424 DNA TagTamper is a version with an additional physical tamper detection feature.

It can detect whether a seal or packaging has been opened, making it ideal for:
Product authentication
Anti-tamper packaging
High-value goods protection
Supply chain security
What makes NFC/RFID NTAG 424 DNA different from normal NFC tags?
NFC/RFID NTAG 424 DNA is a secure NFC chip, not a basic NFC tag.

Key differences include:
AES-128 encryption
SUN (Secure Unique NFC) authentication per scan
Encrypted UID / random ID mode
Anti-cloning protection
Secure messaging (CMAC / LRP encryption support)
Certified hardware security (EAL4+ level)
It is designed for secure digital identity and product authentication, not simple data storage.
What is NFC/RFID NTAG 424 DNA used for?
NFC/RFID NTAG 424 DNA is widely used in high-security applications such as:

Anti-counterfeit product authentication
Luxury goods verification
Secure NFC marketing campaigns
Smart packaging
Ticketing systems with fraud protection
Pharmaceutical supply chain tracking
High-end brand protection
How does NFC/RFID NTAG 424 DNA security work?
NFC/RFID NTAG 424 DNA uses AES-128 encryption + SUN authentication.

Each NFC scan generates a unique cryptographic message, which can be verified by a backend system to confirm authenticity.

This means every tap produces a dynamic, non-replicable identity response.
What is TagTamper functionality?
TagTamper is a physical security mechanism that detects:

If packaging has been opened
If a seal has been broken

Once triggered, the tag can send a different authentication response, indicating tampering.
Is NFC/RFID NTAG 424 DNA secure?
Yes. It is one of the most secure NFC tags available in the market.

Security features include:
AES-128 encryption
Mutual authentication
Secure messaging
Anti-replay protection
Random UID mode
EAL4+ certified hardware security
Can NFC/RFID NTAG 424 DNA be used with smartphones?
Yes.
It is NFC Forum Type 4 compliant and works with most NFC-enabled smartphones.

However, full security verification usually requires a backend system or cloud authentication server.
Can NFC/RFID NTAG 424 DNA be customized?
Yes. We provide full OEM customization:

NFC encoding and programming
Secure key injection (AES personalization)
UID / SUN configuration
Full color printing
Sticker, card, or packaging formats
Anti-tamper label integration
Do you provide OEM manufacturing for NFC/RFID NTAG 424 DNA?
Yes. We are a professional RFID/NFC card manufacturer offering:

OEM / ODM production
Secure NFC chip encoding
Mass production for anti-counterfeit projects
Global shipping support
Custom branding and packaging
What certifications does your factory have?
Union Smart's manufacturing and compliance credentials include ISO9001, ISO14001, ISO45001, SA8000, Sedex, FSC, and IATF16949, with applicable certifications depending on the production site, material and project requirements.
Are you an NTAG® 424 DNA Card manufacturer?
Yes. Union Smart is a source factory providing OEM/ODM NTAG® 424 DNA / DNA Tamper Card manufacturing, NFC programming and customized secure NFC solutions for global B2B customers.
