SKAYIN Ntag215 NFC Tags, 30PCS NTAG 215 Blank PVC Coin NFC Cards 30mm(1.18 inch)504 Bytes Memory,Compatible with All NFC Enabled Mobile Phones & Devices and TagMo Amiibo

Worked perfectly, make sure you know what these are before you buy. If you know what they are, single write cards, then just letting you know that I bought them and they did exactly what they were supposed to do. The finish is great, no weird bumps, no improper cuts, smooth even finish and color. Nice cards.

I’ve used most of the cards and so far they all work exactly as described. No duds like some have reported. Super easy to program with the free app. I’ll buy these again.

Was very easy to write to and all in the pack functioned correctly.

I made some amiibos and they work amazing

Worked great for doing TotK amiibos

Debo seguir probando pues no me funciona en todos los telefonos. Android

Half worked for my purposes but about 5 of them failed to write correctly several times and just didn't work in the end.

Everything works great read and write. Value for the money.

I think whoever packed the cards made a tiny mistake lol I got 51 cards instead of 50..... I'll leave that up to a mistake by a machine and not a human. These cards saved me at least $150 if not more. I'll also be ordering more in the future...... though I wish the seller had a 100 or 200 card option as it'd be much more convenient for me to order in bulk instead of ordering 2-3 or even 3-4 packs of 50.

Can read, write, format and they work without having to be in the app. Just tap the phone to them and it sends the link like I want. 540 bytes like advertised. Had ordered from a different company before and they didn’t work. THESE DO!

They don't work with my Android Samsung 24 as I can scan them and they read but cannot program them however they do work with my family's Samsung s22 lol they can scan and program them. This product was a hit and miss.

The product works well, all tags where working without issues, and it works flawlessly with amiibos for animal crossing new horizons

I have tested a few and they are compatible to mimic Amiibo. Note that you can write once but i havent been able to rewrite them. Still good value for the money. I wont answer question about how to make them into amiibo, google "tagmo".
