NO NFC chip

Cristian Zamora—March 4, 2025

Leaving a 1 Star because you can’t do ZERO nor negative. This does not have a NFC chip in it. It has the letters “NFC” engraved or “chipped” (if you will) on the inside of it. That’s how they get away with saying it has NFC. Looks nice, but does not have the chip. Trash humans playing the system. Read more

Didn't work for me

Chris Hill—September 10, 2022

I wanted to let you know that mine was the wrong size and didn't work for me. I have several different softwares and other NFC tags. I worked with this for two days and nothing. So I guess buyer beware. For full disclosure I also didn't send it back. I bought because of low price, got what I paid for. Read more
