Good day, Guys and Gals I like so many others are looking to back up our Amiibos, That being said after doing some research into hardware/software and looking into things I have android Samsung A40 and Samsung Galaxy SMT-700 tablet they are both writeable. However, Looking into the NFC215 tags/Cards so many are advertised as working with Amiibos/TagMo and such, But are the tag/cards that are 540 bytes but writeable 504, All the files I have looked into for back up are at least 540 bytes are the 540/504 writeable tags/cards really compatible or do I need to look into getting the nearly 1mb tags/cards.

also looking for software suggestions any help would be greatly appreciated.

Many thanks in advance
