Hi there! So over the past few months, I’ve been slowly purchasing and testing cheap alternatives for rfid and nfc implants. Testing included heavy metal testing and swabbing to grow cultures. There has only been one huge offender, and that one checked both the boxes. Anyways, I have a pet tag version of the ntag 216. It works great! That is, until I bought the kbr1. I can not seem to get it working, I’ve looked through the forums and tried the troubleshooting tips. Is it possible that it just won’t scan? And if so, why? Thanks!
