YARONGTECHRFID Sticker tag 13.56mhz Round 25mm Adhesive Back -50pcs

Honestly there is not much to say about this product. It does exactly what it claims and works well for creating custom NFC tags. You can easily read these with an Arduino or Raspberry Pi and a cheap NFC reader/writer.

Used these on a deck of playing cards, and they work great so far. You *cannot* change the unique id (which is actually a good thing), but they are readable and writable. Pretty thin, though a little thicker than a paper sticker. Adhesive is strong, so it may be difficult to remove once you apply it. Great value. Recommended.

The stickers did exactly what I expected. You just hold your phone up to them and it initiates the process on your phone. It's very easy to use.

They are super easy and quick to read from and write on. I had a few in my package that didn't work but it's only been just 4-5 so it's not too big of a deal. Could be more sticky though

I tried to write information to them but no too iPhone app even recognizes them as NFC tags. So they are just expensive stickers.

El pegante del TAG es muy bueno, no se despega solo con el pasar del tiempo y creo que hemos comprado mas de 2000 de estos TAG. funcionan muy bien para leer con NFC de un CAT S42 y recientemente con Samsung, INRICO, y otros celulares mas.

Estos tags los pegamos en una tarjeta de habitación de hotel que funciona con otra frecuencia, para que puedan abrir la puerta de acceso. Funcionan muy bien, los recomiendo.

Does it's job and for a reasonable price. Smart purchase!
