Round NFC coins for Amiibo writers

The board contains 50 round NTAG215 stickers measuring 25 mm across. Each tag offers 504 bytes of NDEF memory and a read-write lock so data can be rewritten or permanently locked. They work with TagMo and any NFC phone at 13.56 MHz under ISO/IEC 14443A and 18000-3 protocols. Not designed for metal surfaces.

Sustained rewrite endurance

The chip is rated for over 100000 read-write cycles, so repeated Amiibo rewrites or frequent tap tests will not wear the tags out quickly. Locking a tag to read-only prevents accidental overwrites during long sessions. Performance stays consistent because the PVC substrate resists moisture and abrasion during handling.

Thermals noise and power in normal use

Passive tags draw zero power and generate no heat or noise during reads or writes. The waterproof PVC coating keeps the antenna stable outdoors or near water without degradation. Adhesive backing lets you mount them on plastic wood or glass, but metal blocks the field so they cannot be used on those surfaces.

Questions about this item

Does the NTAG215 chip generate noticeable heat or draw extra power when I scan it repeatedly all day?

The passive NTAG215 chip has no battery and draws zero power until a phone or reader energises it at 13.56 MHz, so it produces no heat and adds no load to your device.

What device do I already need to read or write these 25 mm NFC stickers?

Any NFC-enabled smartphone, tablet or dedicated reader that supports ISO/IEC 14443A at 13.56 MHz will communicate with the tags.

Will these tags still work if I stick them next to older 13.56 MHz RFID cards I already own?

Yes, the NTAG215 operates on the same 13.56 MHz frequency and ISO/IEC 14443A protocol, so it co-exists with legacy cards without interference.
