The NTAG series from NXP Semiconductors is the world’s most widely deployed family of NFC tags. NTAG213, NTAG215, and NTAG216 share the same ISO/IEC 14443-3A platform and NFC Forum Type 2 compliance — but differ significantly in memory capacity, price, and optimal application fit.

Whether you’re sourcing NFC chips for smart business cards, product authentication tags, gaming applications, or industrial data storage, this guide gives you the technical detail and decision framework to choose the right NTAG variant for your project.

Quick Comparison: NTAG213 vs NTAG215 vs NTAG216

NTAG213 — The High-Volume Workhorse

NTAG213 is the most widely deployed NFC chip globally. With 144 bytes of user memory, it handles the vast majority of real-world NFC applications — from smart packaging to contactless business cards — at the lowest cost per unit in the NTAG family.

NTAG213 Specifications

• User memory: 144 bytes (36 pages × 4 bytes)
• Max NDEF message size: ~137 bytes
• URL capacity: Up to ~132 characters (plain URL, no HTTPS overhead)
• Password protection: 32-bit password + 16-bit password acknowledge (PACK)
• Anti-collision: Supports multiple tags in the field

Best Applications for NTAG213

• NFC business cards: Store a URL linking to a digital profile, LinkedIn, or vCard landing page
• Smart packaging: Tap-to-authenticate or tap-to-reorder product tags
• Marketing campaigns: NFC-enabled posters, flyers, and retail displays with short redirect URLs
• Access control: Low-security door access and time-attendance applications
• Loyalty cards: Simple tap-to-identify cards linked to a backend loyalty system
• Wi-Fi sharing: Store Wi-Fi SSID and password in NDEF format for guest network access

NTAG213 Limitations

• Cannot store full vCard data (name + phone + email + address exceeds 144 bytes)
• Not suitable for offline data storage without a backend URL redirect
• No cryptographic security — password protection only (not suitable for high-security access control)

NTAG215 — The Gaming & Mid-Capacity Chip

NTAG215 offers 504 bytes of user memory — 3.5× more than NTAG213. It became the de facto standard for Nintendo Amiibo figurines, making it the most recognized NFC chip in the consumer gaming market. Beyond gaming, it suits applications requiring moderate data storage at a mid-range price point.

NTAG215 Specifications

• User memory: 504 bytes (126 pages × 4 bytes)
• Max NDEF message size: ~496 bytes
• Amiibo compatibility: Full Nintendo Amiibo specification compliance
• Password protection: 32-bit password + PACK
• Lock bytes: Supports permanent write-lock for read-only deployment

Best Applications for NTAG215

• Nintendo Amiibo clones and custom gaming tags: Compatible with Nintendo Switch, Wii U, and 3DS Amiibo readers
• Interactive collectibles and toys: Store game data, character profiles, or unlock codes
• Loyalty programs with complex data: Store tier status, points balance, and transaction history directly on the card
• Multi-record NDEF messages: Combine URL + text + custom records in a single tap
• Event credentials: Store attendee data, session access rights, and check-in records

NTAG215 Limitations

• Higher unit cost than NTAG213 — not justified for simple URL applications
• Still no cryptographic security — password protection only
• Memory may still be insufficient for large offline data sets

NTAG216 — The High-Capacity Data Storage Chip

NTAG216 provides 888 bytes of user memory — the largest in the standard NTAG series. It is designed for applications that need to store rich, structured data directly on the chip without relying on a cloud backend or internet connection.

NTAG216 Specifications

• User memory: 888 bytes (222 pages × 4 bytes)
• Max NDEF message size: ~880 bytes
• vCard capacity: Full vCard 3.0 with name, multiple phone numbers, email, address, and photo URL
• Password protection: 32-bit password + PACK
• Mirror feature: UID and NFC counter can be mirrored into NDEF data for dynamic content

Best Applications for NTAG216

• Full vCard NFC business cards: Store complete contact information (name, company, phone, email, address, website) without a redirect URL
• Offline data storage: Industrial asset tags storing maintenance records, calibration data, or equipment specs without network dependency
• Medical and pharmaceutical tags: Store dosage instructions, batch numbers, and expiry data directly on the tag
• Multi-function smart cards: Complex NDEF records combining multiple data types in a single credential
• Remote or low-connectivity environments: Applications where internet access cannot be guaranteed at point of use

NTAG216 Limitations

• Highest unit cost in the NTAG series — extra memory is wasted on simple URL applications
• Same password-only security as NTAG213/215 — not suitable for high-security applications (use DESFire instead)

NTAG213 vs NTAG215 vs NTAG216: How to Choose

Use this decision framework to select the right chip for your project:

• Choose NTAG213 if your application stores a URL, Wi-Fi credentials, or simple text. It covers 90%+ of NFC business card, smart packaging, and marketing tag use cases at the lowest cost.
• Choose NTAG215 if you need Amiibo compatibility, moderate data storage (up to ~496 bytes), or are building gaming/interactive collectible products.
• Choose NTAG216 if you need to store full vCards, offline structured data, or multi-record NDEF messages exceeding 504 bytes — especially in environments without reliable internet access.
• Consider MIFARE DESFire EV3 instead if your application requires cryptographic security (AES-128), multi-application support, or audit trail capabilities — the NTAG series uses password protection only and is not suitable for high-security access control or payment applications.

Frequently Asked Questions (FAQ)

What is the difference between NTAG213, NTAG215, and NTAG216?

The primary difference is user memory capacity: NTAG213 has 144 bytes, NTAG215 has 504 bytes, and NTAG216 has 888 bytes. All three use the same ISO/IEC 14443-3A standard, operate at 13.56 MHz, and support 32-bit password protection. The choice depends on how much data you need to store on the chip and your budget.

Which NTAG chip is used in Nintendo Amiibo?

Nintendo Amiibo figurines use the NTAG215 chip. The 504-byte memory capacity is sufficient to store Amiibo game data, and the chip’s lock byte support allows Nintendo to write-protect the Amiibo data region while keeping a user-writable area. NTAG213 does not have enough memory for Amiibo data, and NTAG216 is compatible but unnecessarily expensive for this application.

Can NTAG213 store a full vCard?

No. A complete vCard 3.0 with name, company, phone, email, and address typically requires 300–600+ bytes, which exceeds NTAG213’s 144-byte user memory. For full offline vCard storage, use NTAG216 (888 bytes). Alternatively, NTAG213 can store a short URL linking to an online vCard or digital business card profile.

Are NTAG chips secure enough for access control?

NTAG chips support 32-bit password protection, which is sufficient for low-security applications like gym access or loyalty card identification. For high-security access control (corporate buildings, data centers, government facilities), MIFARE DESFire EV2 or EV3 with AES-128 encryption is strongly recommended. NTAG chips do not support mutual authentication or encrypted data storage.

What is the maximum URL length an NTAG213 can store?

NTAG213 can store approximately 132–137 characters of URL data in NDEF format (accounting for NDEF header overhead). HTTPS URLs with short paths fit comfortably. For longer URLs with query parameters or UTM tracking codes, use NTAG215 or NTAG216, or use a URL shortener service.

What is the read range of NTAG213, NTAG215, and NTAG216?

All three chips have the same read range: typically 1–10 cm depending on the reader antenna size and tag antenna design. The memory capacity does not affect read range. Larger tag antennas (e.g., credit card size vs. coin size) generally achieve longer read distances.

Can I use NTAG216 instead of NTAG215 for Amiibo?

Technically yes — NTAG216 is ISO/IEC 14443-3A compliant and has more memory than required for Amiibo data. However, Nintendo’s Amiibo specification targets NTAG215, and some Amiibo writing tools may not correctly handle NTAG216’s larger memory map. NTAG215 is the recommended and most compatible choice for Amiibo applications.

What is the MOQ for custom NFC cards using NTAG chips?

For custom-printed NFC cards or tags using NTAG213, NTAG215, or NTAG216, minimum order quantities typically start at 100–500 units for standard designs and 500–2,000 units for fully custom OEM orders with encoding. Sample orders are available for pre-production testing.
