How to use the NFC function on the mobile phone?

There will be a "Setup" or "Control" command on the phone, which can be used after the phone is turned on.

The use of NFC is very simple. It only takes one step to turn on this function. There will be a "set" or "control" command on the phone. Find the "NFC function" in the corresponding control center, and you can use the NFC function normally as long as it is lit or turned on.

NFC function is a wireless communication technology. If the mobile phone carries this function, data exchange between two devices can be realized in a short distance, and network data does not need to be turned on during data transmission and communication, so the mobile phone can be used normally even if it is disconnected from the network. The greatest thing about NFC is that it can simulate bus cards, access cards and even bank cards. In other words, as long as the mobile phone is in hand, these cards can be kept at home. When taking the subway, the mobile phone becomes a subway card, which is very convenient. Let's talk specifically about how to complete various practical functions with mobile phones. The first is to simulate the situation of access cards. Take Huawei brand mobile phones as an example. We need to "input" the information of the access card into the mobile phone. In Huawei's mobile phone, there is a wallet APP, in which you can select an access card, and then put the access card on the mobile phone, and the information of the access card will be read by the mobile phone. The next time you enter the door, just put your mobile phone on it and the entrance guard will be opened, which is very convenient. Other usage is similar, as long as you select the corresponding card, you can replace it with your mobile phone when reading the card information, such as bus card and bank card. In addition to analog card information, NFC function can also be applied to audio with Bluetooth function. When the NFC function is not turned on, you should operate it every time you connect the stereo. However, as long as the function is turned on, when using the stereo, you only need to put your mobile phone near the Bluetooth stereo, and you can automatically connect the stereo, which is more time-saving and labor-saving, which is very convenient.
