The NFC chip in an iPhone allows easy ApplePay. No wifi or Bluetooth needed. Everyone says that the NFC chip defaults to "on". But on my iPhoneSE, in the Control Panel, I found it turned "off". I never turned it off. What's the deal? Is it on by default or not?
iPhone SE (2nd generation)
You’re welcome.
It’s occasionally a point of some confusion.
As NFC’s range is only a few inches and it’s power consumption is minuscule; a decision was apparently made to NOT add user confusion and the opportunity for malfunction which an “on/off” switch would surely cause.
(e.g. “My ApplePay will not work” or “My Transit Pass will not work.” )
Thanks for the reply.
That’s not “NFC” … that is your mobile network. (i.e. your mobile carrier’s voice, SMS, and data)
There is no user-facing “on/off switch” for NFC nor is there any “NFC Status” indicator.
Uh, duh. Really? Thank you! I saw somewhere that was identified as NFC. Aargh. Now I see the "NFC tag reader" icon does not appear on my iPhone SE, and is not available in Settings/Control Center. So is it not possible to turn it on and off? Do I then assume that it is always on in an iPhone SE (Gen2)??
This is my control panel when NFC is turned on. Button is green. It was not originally green.
I had to press it to make it green.
NFC is indeed normally “on.”
Can you possibly post a screenshot of your “Control Panel” ? …
… being careful to redact any personally identifiable information.
That is correct. (Always “on”)
Thank you very much. That makes a lot of sense. The iPhone SE doesn't even have a control for NFC. It's just ALWAYS ON.
That's also useful to know that the power consumption of NFC is minimal. That is, in order to extend battery life, it doesn't really matter if NFC gets turned off.
when is NFC on?
