A quick compatibility check
Small tag.
Different possibilities.
Not every tag holds the same amount. NTAG213 fits compact filament profiles; NTAG215 and NTAG216 have room for larger datasets.
Choose the layout your printer or reader understands. More memory alone does not add ecosystem compatibility.
| Format | Compatible tags |
|---|---|
| Anycubic ACE | NTAG213 / NTAG215 |
| Elegoo | NTAG213 / NTAG215 |
| OpenTag3D | NTAG215 / NTAG216 |
Requires an NFC-capable iPhone with iOS 18 or later. OpenTag3D does not fit NTAG213. Reading leaves a tag unchanged; writing replaces the filament data on the tag you choose.
What are NTAG tags, and which should I buy?
A tiny memory chip, inside an NFC sticker. NTAG is a family of NFC chips made by NXP. A finished tag includes the chip and an antenna; your iPhone reads or writes it at close range, without a battery.
A straightforward starting point: blank, writable NTAG215 stickers. NTAG215 is listed for all three formats currently supported by SpoolRFID: Anycubic ACE, Elegoo, and OpenTag3D. Choose the matching format in the app before writing.
Look for a listing that explicitly says NTAG215, 13.56 MHz, NFC Type 2, rewritable and unlocked. Buy finished stickers or discs, not bare chips, and check that their dimensions and placement suit your spool and printer reader. A tag cannot add support for a format your printer does not understand.
NTAG213 is an option for the compact Anycubic ACE and Elegoo layouts listed above. For OpenTag3D, choose NTAG215 or NTAG216; NTAG213 is too small.

Sticker placement
A good spot makes a difference.
Illustrative positions, not to scale. The printer’s reader location determines where the sticker belongs.
Made for the way you print
Less tag wrangling.
More making.
