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

work great

works good

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.

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 .
