50 Pieces NFC Tags NTAG215 NFC Stickers Programmable NFC Tags Sticker Waterproof NFC Chip with Adhesive Back,Compatible with TagMo and NFC Enabled Devices（1 inch）

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

Tags stick fairly well and seem to work just fine .

This was one of the better deals in terms of cost/tag. So far, I've used about 20 of them and they have all worked as expected. It's super cheap and easy to use. I'm using them with Bixby on my Galaxy Fold but any phone with NFC capabilities can leverage them. I also recommend using NFC Tools if you are an Android user.

These sound a lot better than they work. NFC interaction works, but is finicky. I'm using these with a 3rd-gen iPhone SE to activate Shortcuts automations. Setup is easy. You have to tap them very deliberately to guarantee they scan on the first tap. The motion is almost a press and hold on the NFC - a swipe or tap might not work. Maybe newer phones are more responsive.

This is nice

Not great. Size is good, but the NFC tag doesn't work most of the times. Needs a lot of fiddling and adjusting to detect on the phone. Not worth the effort. The glue is really strong and takes a great deal of effort to get off once stuck.

I wanted to make digital business cards for myself for a while, so I decided to buy my own set of NFC chips and started 3d modeling, testing the chip by using nfc tools and it wrote the url link very easily and I glued the back of the nfc chip with a little bit of adhesive glue and glued together the top and bottom of the keychain and it worked while the it’s in the inside of the 3d model and I am so happy that it worked out well.

These tags work as expected when first written. I’ve been using them for about 2 months. But, when I erase a tag, using NFC Tools, I can rewrite new data, and read the data using NFC tools app, but normal nfc tap does not read the chip. For one time use they seem great. I’ll update after six months or so.

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.

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!

Good product, I programmed a url to them and they're flawless with android phones but I can't get them to work on iphones. Iphones can't seem to read them, am I missing something? Please help! Nick

Picked these up to start improving my home automation experience, and they just work out of the box. I use Tasker with Home Assistant to add functionality to these tags, which allows me to do things like turn on my entire TV and AVR set-up with one scan, set timers for my washer/dryer/dishwasher, turn off lights in a specific part of my house, and many more. Comes with 3M adhesive, which causes the tag to stick really well to near enough everything. Update: I recently placed one of these on my washer and found that it doesn't work at all in this use case. As soon as I took it off and placed it on plastic, everything was fine, so just bear this in mind.
