2018 Apple iPhones Support Background NFC Tag Reading

Apple has launched its 2018 iPhone lineup of devices that included iPhone XS, iPhone XS Max, and iPhone XR in Cupertino, California. While the iPhone XS and iPhone XS Max makes use of the design from iPhone X by getting an slight upgrades in the hardware, cameras, and a new Gold colour option, the new iPhone XR is introduced as the low-cost LCD alternative.

But all of these three new iPhones variants has an upgrade in the form of background reading of NFC tags, which has been designed to work when a iPhone is in use in order to avoid unintentional tag reading. The NFC tag reading will not work if the iPhone hasn't been unlocked, a core NFC reader is in session, Apple Pay Wallet or camera is in use, or even in enabled Airplane mode.

"On iPhones that support background tag reading, the system scans for and reads NFC data without requiring users to scan tags using an app. The system displays a pop-up notification each time it reads a new tag. After the user taps the notification, the system delivers the tag data to the appropriate app. If the iPhone is locked, the system prompts the user to unlock the phone before providing the tag data to the app."

This new background tagging function will permit the device users to scan any NFC tag at a museum, store, or other location without first having to open up an app. NFC tag scanning will present a notification on the display, which can be tapped to launch an app. It requires users permission grant to launch an app by tapping on it.

This NFC-compatible app is limited to the iPhone XS, XS Max, and XR. It is not supported on iPhone X and earlier models.
