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

Works like a charm ! Size is literally like the photo easy to use , great price for 50 pcs is a win ! I use nfc tools to write

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!

Tags stick fairly well and seem to work just fine .

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.

Easy to program and inexpensive to hand out. I used these for making my own review signs - stuck it on the back and gives customers the ability to hold their phone nearby and links to the review!
