When planning an NFC project, many businesses ask:

Should I use NTAG216 or upgrade to NTAG424 DNA?

Both chips are manufactured by NXP and operate at 13.56 MHz NFC frequency. Both can be read by Android smartphones and iPhones, and both are widely used in NFC tags, labels, cards, and packaging.

However, these two chips are designed for completely different purposes.

• NTAG216 focuses on information sharing and consumer engagement.
• NTAG424 DNA focuses on authentication, security, and anti-counterfeiting.

Choosing the wrong chip can result in:

❌ Weak product security

❌ Unnecessary development costs

❌ Poor user experience

❌ Future migration challenges

This guide compares NTAG216 and NTAG424 DNA in detail, helping you choose the right chip for your project.

Quick Answer

Choose NTAG216 if you need:

✅ Digital business cards

✅ Product information pages

✅ Smart packaging

✅ Restaurant menus

✅ Marketing campaigns

✅ Customer engagement

Choose NTAG424 DNA if you need:

✅ Product authentication

✅ Anti-counterfeit protection

✅ Digital Product Passports (DPP)

✅ Luxury goods protection

✅ Pharmaceutical traceability

✅ Wine and cosmetics authentication

What Is NTAG216?

NTAG216 is one of the most popular NFC chips for consumer interaction and marketing applications.

Compared with NTAG213, it offers significantly larger memory, making it ideal for storing:

• Long URLs
• vCards
• WiFi credentials
• Product information
• Small data records

The chip is inexpensive, easy to program, and compatible with almost all NFC-enabled smartphones.

NTAG216 Specifications

What Is NTAG424 DNA?

NTAG424 DNA is a secure NFC chip specifically developed for:

• Product authentication
• Brand protection
• Anti-counterfeiting
• Secure consumer engagement

Its most important feature is:

Secure Dynamic Messaging (SDM)

Every tap generates unique encrypted authentication data.

The chip supports:

• AES-128 encryption
• Dynamic URLs
• Dynamic CMAC
• Secure backend authentication

NTAG424 DNA vs NTAG216 – Technical Comparison

The Biggest Difference: Information vs Authentication

This is the easiest way to understand the two chips.

Authentication comes first.

Security Comparison

NTAG216 Security

NTAG216 supports:

• Password protection
• UID
• Lock bits

However, the data stored inside the chip remains static.

Example:

https://brand.com/product123

Every scan returns exactly the same information.

A counterfeiter can:

1. Read the tag.
2. Copy the URL.
3. Program another NFC tag.

NTAG424 DNA Security

NTAG424 DNA uses:

• AES-128 encryption
• Secure Dynamic Messaging
• Dynamic CMAC
• Dynamic URLs

Example:

https://brand.com/auth?e=xxxxx&c=yyyyy

The authentication data changes every time.

A copied URL becomes useless.

Why Memory Size Can Be Misleading

Many buyers assume:

More memory = Better chip.

This is not necessarily true.

NTAG216

888 Bytes of memory.

Ideal for:

• Long URLs
• Digital brochures
• Product information
• vCards
• Rich content

NTAG424 DNA

416 Bytes of memory.

Although smaller, the memory is optimized for:

• Authentication keys
• Secure URLs
• Dynamic data
• Digital identities

For authentication projects, 416 bytes is usually more than sufficient.

Smartphone Compatibility

Both chips work with:

✅ Android phones

✅ iPhones

No dedicated app is required for normal URL opening.

Development Complexity

NTAG216

Very simple.

Example:

NTAG424 DNA

Requires:

• Authentication server
• AES key management
• Backend verification
• Dynamic URL processing

Complexity:

Medium.
