Timeskey NFC 50 pcs Tags Stickers Programmable Tags Rewritable Cards Chip Ntag215 25mm Coin Adhesive，Compatible with TagMo iPhone and Enabled Devices

I got the white 20 pc for $6.90 to make acnh amiibos and they do the job perfectly fine.

Did a deep dive on NFC last year, found out a modern IPhone can not only read, but also program these with a free app (NFC Tools). I programmed several including with my contact info for tradeshows and conferences, I programmed some with my website, some with my youtube channel and certain instructional videos, I understand you can even program them with your WIFI information so guests can quickly tap their phone and access your internet (think Air BNB?) These worked perfect, coin sized, easy to carry in your pocket and came with adhesive on the back for mounting. Own a business? Stick one on the counter so customers can leave a review! (you program it with the URL that leads to the review page). I think everyone can use these once you understand what they can do!

I used them to write some custom Animal Crossing amiibos as well as a way to share our Wifi password, and they worked without a hitch. My phone is an old Xiaomi Mix 2, and it had no issues writing the tags, so if you have something more recent, you should be fine.

Work great, easy to use, seem to have a decent durability. Worth the money, especially if you don’t need a ton of them.

Works great with iPhone I used them up already.
