20 NTAG215 NFC Stickers for Home Assistant

This pack contains 20 round white NFC stickers built on the NTAG215 chip. Each tag measures 25 mm in diameter and carries an adhesive back for quick mounting on non-metal surfaces. The chips offer 504 bytes of usable memory and support more than 100000 write cycles. They operate at 13.56 MHz and follow the ISO/IEC 14443A protocol.

Suitable for Amiibo and automation.

The stickers work with TagMo and any NFC-enabled phone or reader, making them useful for Amiibo emulation, home-automation triggers or simple data sharing. Buyers who need tags that function directly on metal surfaces should look elsewhere because the adhesive layer does not overcome metal interference. The PVC construction is waterproof and rated for 10 years of data retention.

NTAG215 chip with 504 bytes user memory

The decisive specification is the NTAG215 integrated circuit providing 504 bytes of writable storage out of 540 bytes total. This capacity determines whether a specific Amiibo dump or automation payload will fit. The tags are supplied new in a 20-piece pack weighing 0.018 kg with overall packaging dimensions of 14.33 in by 12.83 in by 9.06 in.

Questions about this item

Does the pack of 20 white NTAG215 stickers include any reader or programming tool, or are those bought separately?

The box contains only the 20 adhesive-backed tags; no reader, writer or software is included. Any NFC-enabled phone or dedicated reader must be purchased separately.

The listing mentions both 504 and 540 bytes — which capacity should I rely on when choosing tags for Amiibo data?

Use the 504-byte figure; that is the user-available memory. The 540-byte total includes reserved system space that cannot be written.

What does the 13.56 MHz operating frequency mean for everyday use with a smartphone?

It is the standard NFC frequency, so any phone with NFC turned on can read and write these tags at close range without extra hardware.
