The iPhone XR, iPhone Xs and iPhone Xs Max do feature support for NFC, but there is a little twist that you guys might not have guessed and it is a feature that Apple did not mention on stage either. The brand new models will be able to scan NFC tags without requiring the need to fire up an app to do it.

In short, if you own an iPhone XR, iPhone Xs, or an iPhone Xs Max, you can simply walk up to a compatible NFC tag, wake the iPhone screen, and scan it seamlessly. When the NFC tag has been detected by the iPhone, 9to5Mac reports that it will trigger a notification to appear on the lock screen of the iPhone Xs or iPhone XR. The user can then tap the alert and launch the app into the foreground.
