Hello, I'm trying to read custom NFC (13.56mhz) tags with my iPhone using an NFC app, but none of them seem to be working (I've tried the three most popular NFC apps). I am writing text to these tags using a RC522 connected to a Raspberry Pi.
I know that my scanner is working because I can read and write text to tags. I know NFC on the iPhone is working because the scanner also detected the signal when I opened and activated Apple Pay. Besides that, I am using known-good tags (such as a hotel room key) that also work with my scanner but not my iPhone.
Has anyone else encountered this issue? Is there a solution?
Thanks.
