Viator Gear NTAG215 NFC Keyholder 10 Pack 504 Bytes Black

Pack contents and format

Each package contains 10 black NFC key fobs. Every tag uses a genuine NTAG215 chip with 504 bytes of usable memory and a key ring for attaching to keys or bags. The ABS shell resists temperatures up to 190 degrees Fahrenheit and is rated for 100,000 write cycles with a 10-year data life. The tags operate at 13.56MHz under ISO/IEC 14443A and 18000-3 protocols.

Who this suits and who it does not

The fobs work with any NFC-enabled phone and the TagMo app, making them suitable for storing Amiibo data, Wi-Fi credentials, contact details or smart-home triggers. They cannot be used directly on metal surfaces and once a tag is locked to read-only it cannot be rewritten. Buyers who need on-metal mounting or larger memory capacity should consider a different form factor.

Chip specification and lock behaviour

The NTAG215 chip provides 540 total bytes with 504 bytes available for user data and supports password-protected authentication. A read-write lock can be applied to make the tag permanently read-only, after which it cannot be edited or reset. This one-time lock decision is the critical factor when planning how the tags will be deployed.
