- Amiibo Protocol Compatibility: Compatible with Nintendo Switch, Wii U, and 3DS console hardware.
- Static & Dynamic Locking: Allows vendors to permanently lock specific memory sectors while leaving other blocks open for user progress saves.
Recommended Deployments
- Screen-Free Audio Players & Toys: Physical tap-to-play cards triggering stories, audiobooks, and children's smart speaker playlists.
- Interactive Collectibles & Gaming: Figurine bases, trading card games, and character stat unlock tags.
- Event Badges & Multi-Tier Access: Credentials storing attendee profile metadata, VIP access tokens, and check-in counters.
3. NTAG216 — The High-Capacity Offline Storage Chip
NTAG216 delivers 888 bytes of user memory, the maximum storage capacity in the standard NTAG series. It is engineered specifically for applications that require dense, structured information stored locally on the chip without relying on internet access or cloud databases.
Key Architectural Capabilities
- Maximum Data Density: 222 user pages (888 bytes) capable of storing full vCard 3.0 electronic business cards offline.
- UID & Counter Mirroring: Automatically appends the chip's unique 7-byte serial number and tap counter directly into the NDEF payload.
- Industrial Robustness: 10-year data retention and 100,000 write cycle endurance across industrial temperature ranges.
Recommended Deployments
- Complete Offline vCard Cards: Stores full contact information (name, direct phone, email, company, address) readable by any smartphone without network access.
- Industrial Machinery Maintenance Tags: Encodes equipment service logs, inspection dates, and calibration values directly on the machine.
- Medical & Emergency Credentials: Encodes blood type, emergency contact numbers, and prescription notes directly on patient wristbands.
Decision Framework: Which Chip Should You Choose?
- Select NTAG213 if your project links to an online URL, cloud database, or web landing page. It delivers the highest cost efficiency for mass-market tags and basic smart cards.
- Select NTAG215 if you are manufacturing gaming collectibles, Amiibo-compatible accessories, or interactive audio cards requiring moderate data payloads.
- Select NTAG216 if your application requires offline vCard contact storage, equipment maintenance logging, or multi-record NDEF payloads exceeding 500 bytes.
- Consider MIFARE DESFire EV3 instead if your project demands hardware cryptographic encryption (AES-128), financial transactions, or government-level security. Explore our MIFARE DESFire EV3 Cards for encrypted access control systems.

B2B Technical & Sourcing FAQ
Q1. Can an NTAG213 tag store a complete vCard contact profile?
No. A standard vCard 3.0 containing a person's full name, job title, company, direct telephone, mobile number, email, and physical address requires between 300 and 650 bytes of memory. NTAG213 only offers 144 bytes of user space. For complete offline vCard storage, NTAG216 (888 bytes) is required. Alternatively, NTAG213 can store a short URL that redirects to a hosted digital profile.
Q2. Can Union Smart pre-encode and lock NTAG chips during factory production?
Yes. Our high-speed automated personalization equipment encodes your specific NDEF URLs, application strings, or variable records across millions of units. We can configure permanent OTP read-only locks or 32-bit password protection so end-users cannot alter or corrupt the programmed data.
Q3. Does chip memory capacity affect reading range?
No. Reading distance is determined strictly by the physical antenna geometry, tag dimensions, operating frequency (13.56 MHz), and the RF power output of the reader hardware. NTAG213, NTAG215, and NTAG216 share identical RF front-end architectures and provide identical read range under the same antenna tuning.
Q4. Can NTAG215 and NTAG216 be used with iOS and Android smartphones?
Yes. All three chips comply with the NFC Forum Type 2 Tag specification and ISO/IEC 14443-3A. Modern iPhones (iPhone 7 and later running iOS 13+) and NFC-enabled Android devices support background NFC reading and writing natively without requiring third-party applications.
