YARONGTECH RFID 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.

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

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.

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

Works as promised. However, it doesn't work if you stick it on to back of cell phone, so be aware. (It was written on the product description which I didn't see until it arrived, so it is my fault).

These are compatible MiFare RFID stick-on tabs. Programmable with your phone's NFC and free apps on Google play. The functionality is amazing for the price .

work great

works good

Not 1k these are 64 byte mifare ultralights. Scanned with my NFC scanner bought these to write tags for my 3d printer. These will not work.
