NTAG213 vs NTAG215 vs NTAG216: Which NFC Chip Fits Your Project?

✎ Updated September 12, 2026: added a reader-FAQ section covering 2026 NFC market growth, where NXP's new NTAG X DNA fits, mixing chip models in one deployment, and the current NTAG supply situation.

If you're ordering NFC tags and don't know which chip to pick, you're not alone — the NTAG21x family looks almost identical on paper. Here's the practical difference, with the actual decision logic we use when helping customers choose.

The Short Answer

NTAG215 is the safe default. It has enough memory for business cards, larger URLs, and most automation payloads, at a price only marginally above the NTAG213. Choose the NTAG213 only when you're writing very short data and buying in the millions. Choose the NTAG216 when you genuinely need the space.

Side-by-Side Comparison

Memory Math: What Actually Fits

The usable NDEF space determines what you can write. A few worked examples:

• Short URL (e.g., https://clrfid.com ≈ 20–60 bytes): fits on all three chips.
• Typical vCard (name, phone, email, title, company ≈ 250–350 bytes): fits on NTAG215 and NTAG216, too big for NTAG213.
• WiFi payload (SSID + password + encryption ≈ 80–120 bytes): fits on all three, but tight on NTAG213 with long passwords.
• Full vCard with photo or multiple URLs (600–800 bytes): NTAG216 only.

Does Chip Choice Affect Phone Compatibility?

No — all three are ISO/IEC 14443 Type A at 13.56 MHz, read by every NFC-enabled Android phone and iPhone 7 or later. The choice is purely about memory and unit cost.

One Compatibility Trap to Avoid

If your application requires tags to be locked (permanently read-only) after encoding, note that locking is one-way. Always test encoding and reading on your final chip before locking a batch.

Cost-Optimized Alternatives

NT21x-compatible chips from domestic manufacturers (e.g., Fudan) perform the same function at a lower cost for large-volume projects. If price-per-tag is critical above ~500K units, ask us about compatible alternatives — we'll quote them transparently with the actual chip model listed.

Decision Summary

• Millions of tags, short URLs → NTAG213
• Anything involving contact sharing, business cards, or automation → NTAG215
• Large records, photos in vCards, multi-function apps → NTAG216
• Unsure? → Start with NTAG215; it's the industry default for a reason.

Reader FAQs (Added September 2026)

Is the NTAG21x family still the right default in 2026?

Yes. Demand keeps growing — market research firm MarketsandMarkets projects the global NFC market to expand from US$18.05 billion in 2026 to US$37.42 billion by 2032, a 13.5% CAGR — and the NTAG21x family remains the volume default for marketing, packaging, and asset tags. The main thing that changed in 2026 is supply and pricing, not fitness for purpose: NTAG prices have risen and lead times stretched in some channels. Plan orders a little further ahead than you did in 2025, and get the chip model confirmed in writing when you place an order.

What about NXP's newer NTAG X DNA?

Different class of product. The NTAG X DNA is NXP's first ISO/IEC 14443-4 Type 4 tag — up to 16 KB of memory with PKI-based asymmetric authentication — aimed at device authentication and the EU's incoming Digital Product Passport (DPP) requirements. It solves a different problem: proving a product is genuine and carrying lifecycle data, not cheap consumer engagement. For typical marketing and asset-tracking tags, NTAG21x (Type 2) chips remain cheaper and universally readable. If your roadmap includes DPP compliance or anti-counterfeiting with cryptographic verification, evaluate Type 4 secure chips like NTAG X DNA early — the memory and security architecture change how the tag is encoded and integrated.

Can I mix NTAG213 and NTAG215 in the same deployment?

Yes. All three chips are ISO/IEC 14443-A Type 2 tags — phones and readers treat them identically, and only usable memory differs. The practical advice from our production floor: keep one chip model per product SKU so encoding and QC stay simple, but mixing is completely fine for phased rollouts or when a payload outgrows the NTAG213 mid-project. Just make sure your encoding files specify the chip per batch so the right memory map is used.
