50pcs NFC Cards NFC Tags Ntag215 chip NFC215 tag rewritable NFC Coin Cards， Compatible with Tagmo and NFC Enabled Mobile Phones and Devices, Round (25 mm/ 1 Inch)

These things just super easy and fun to use for all kinds of different stuff. Great value for the money. They don't adhere to anything. There's no stickiness. They function perfect. They're great

These work exactly as advertised.They store data. You can scan their data. They don't instantly bend/snap if any pressure is applied.All in all, a pretty good value for what you get.

Used these to create amiibo cards for smash bros. They work pretty well, even after a few years

These tags seem to work well. Not that it's a big deal but the memory of these (at least the batch I got) is 492 bytes not 504 bytes. They also have a hard plastic case, so they can't be bent to fit into curved spaces. I've used others that were soft & formable. Just so you know if interested. Overall I'm pretty happy with the purchase.

These are excellent quality NFC discs. I use them in class as part of a lecture. The functionality readability and size are excellent for what they are intended to do. They’re inexpensive enough for me to buy them and give them out to my students as part of the Lab.

You know what you want to buy this for. Just know, they work. They're pretty easy to lose in darker areas though, so keep them somewhere secure.

Product says it’s a sticker but description says it doesn’t have adhesive. Pick a lane. Turns out it has no adhesive.But they work fine, albeit a little slow to scan.

In today's world, NFC chips are everywhere. I bought these to include in special order 3D prints for companies. One tap of a smartphone and bam... Their store front, contact information or even payment page pops up.
