Frequently Asked Questions
Helpful answers for getting started and troubleshooting.
Which NFC tags work with AmiiNest?
AmiiNest works with blank NTAG215 tags only. Cards, stickers, and coin tags can all work. NTAG213 and NTAG216 tags are not supported.
Does AmiiNest include encryption keys or amiibo files?
No. AmiiNest does not provide encryption keys or amiibo .bin files. You import your own key file and load amiibo data by importing a .bin file or scanning an amiibo you own.
Can a tag be rewritten?
No. Once a write succeeds, the tag is locked and cannot be rewritten.
How do write credits work?
New users start with 5 free writes. A credit is used only when writing succeeds, and write credits never expire. You can get more by watching an ad (+1 write), buying a write pack, or unlocking Lifetime Unlimited.
Will my write credits move to a new iPhone?
Write credits are stored on your iPhone and don't automatically sync between devices. They may transfer when you restore your new iPhone from a backup. Lifetime Unlimited can be restored on other compatible iPhones using the Apple Account used for the purchase.
I bought Lifetime Unlimited, but the App doesn't show it.
In AmiiNest, go to Settings and tap Restore Purchases. If it still doesn't appear, tap Sync with App Store in the Support section and sign in with the Apple Account you used to buy it.
Writing failed. What should I do?
Hold the tag near the top of your iPhone and follow the on-screen instructions. If the connection is lost during writing, move the same tag slightly when prompted so AmiiNest can reconnect and continue. A credit is used only if the write succeeds. If the App says the tag is locked or has already been used, try a new blank NTAG215 tag.
Which iPhones are supported?
AmiiNest requires a compatible iPhone with NFC support running iOS 18 or later.
