I know it's not possible for the iPhone 6 to read RFID tags, and I know that the iPhone API only allows use of NFC for Apple Pay, but is it possible to read an iPhone's NFC chip as if it were an RFID tag?
That is, would an RFID reader be able to retrieve any sort of passive information like a chip's unique ID or something of that nature, by using an RFID reader with something like an Arduino or Raspberry Pi?
It appears that it is possible to detect the signal coming from the iPhone when you hold down your thumb to attempt an Apple Pay payment. However, it sends out a different ID number with each press. This makes it pretty much impossible to do anything security related.
Here is a video of someone who got it working. https://www.youtube.com/watch?v=fhpMVFte2mE
because the iPhone spits out different NFC tag #'s each time. the reader is set to use any tag this is not good for secure applications like locks like in the video above.
