NFC, also known as near field communication, is a short-range high-frequency wireless communication technology, which allows contactless point-to-point data transmission between electronic devices (within ten centimeters) to exchange data. For example, it can be used to brush subway buses and so on.

To turn on the NFC function, take Huawei P50 Pro mobile phone as an example:

1. Slide out of the control center at the top of the right side of the screen and turn on the NFC shortcut switch.

2. Enter the settings, search and enter NFC, and turn on the NFC switch.
