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.

Excelente tamaño para hacer llaveros con NFC

Solid plastic, read/write very easily with an nfc enabled phone. Great for making your own amiibos

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 work to make Nintendo Switch Amiibos! Figure out the rest on your own... But 100% these work if you need them for your Nintendo Switch. Each can be written to ONLY ONCE.

Easy to use. worked great. I added them to several things for business card style data. Easy to program. Good pricing.

Product works, size is ok, my only issue is that I orded 100 but only got 72. That is disaaponting to know that I did not get the amount I paid for. I can forgive 2 or 3 missing but 28 that is alot.

Works as expected.Be aware that do not work with many Android phones. Works with all iPhones so far from.Do not stick with clubber like I did at the back of your iPhone or else it may not work as expected (I did that thinking I could put it close to other iPhones for networking purposes) but that didn’t work. The nfc needs to be close other phone so it works and has to be where your iPhone camera is located.Tips: make sure you add some stickers to your nfc so when networking it is easy to recognize which nfc tag is about.
