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

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 do not work well. Getting them to scan takes way more effort than manually running some of the automations would be.

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.
