NFC (Near Field Communication) is a wireless connectivity technology that enables two-way communication between electronic devices.

It operates over a distance of a few centimeters. You can share your content with an NFC tag or another NFC support device by simply touching it with your device.
If you touch an NFC tag with your device, it will display the tag content on your device.

Switch NFC on or off:
From the Home screen, touch and slide the notification panel down with your finger, then select the NFC icon to turn it on.

When airplane mode is activated, the NFC application can be used.
