The use of NFC is very simple. It only takes one step to turn on this function. There will be a "Settings" or "Control" command on the mobile phone. Find "NFC Function" in the corresponding control center and just light it up. Or turn it on, and you can use the NFC function normally.

NFC function is a wireless communication technology. If a mobile phone carries this function, it can realize data exchange between two devices over a short distance, and there is no need to turn on network data during data transmission and communication. , so this function can be used normally even if the mobile phone is disconnected from the Internet. The greatest thing about NFC is that it can simulate bus cards, access cards, and even bank cards. That is to say, 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. It's very convenient. Let’s talk specifically about how to use mobile phones to complete various practical functions. The first is to simulate the situation of access control cards. Taking Huawei brand mobile phones as an example, we need to "enter" the access control card information into the mobile phone. In Huawei mobile phones, there is a wallet APP, in which you can select access control cards. Then put the access control card on your mobile phone, and the information on the access control card will be read by the mobile phone. When you enter the door next time, you only need to put your mobile phone on it and the access control will be opened, which is very convenient. Other usages are similar. Just select the corresponding card and let your phone read the card information. The next time you use the card, you can use your phone instead. Bus cards and bank cards can be simulated. In addition to simulating card information, the NFC function can also be used on speakers with Bluetooth functions. When the NFC function is not turned on, you need to operate it every time you connect to the speaker. But as long as the function is turned on, you only need to put your phone in when using the speaker. When you get close to a Bluetooth speaker, it will automatically connect to the speaker, which saves time and effort and is very convenient.
