What is NFC in your phone? Learn these tips and improve your life efficiency by 50%

Nowadays, many mobile phones have many functions, which are dazzling, such as infrared function, which can turn on the air conditioner and TV, and the confusing NFC function. Many people don’t understand the function of NFC. The advantage of this function is that it does not rely on the network and has a high safety factor. Let’s take a look at how this function can optimize our lives.

First of all, you can transfer files quickly. When you and your friends turn on NFC at the same time, you can transfer files without consuming traffic for large-scale file transfers. For example, on a Huawei phone, you can click the huanwei share function key to connect devices and transfer files, which is faster and safer.

In addition, NFC can also be used as access cards, transportation cards, bank cards, and electronic ID cards. You can open your phone and swipe directly, eliminating a lot of inconvenience. Take the access card as an example. First, you need a physical access card, take out a mobile phone with NFC (such as Huawei), and turn on the built-in "wallet" function. Select "Card Wallet" and click on the upper right corner. At this time, make sure NFC is turned on, then create a blank card, and stick the physical access card on the back of the phone, you can directly read the information inside, and the phone will retain our information.

From the perspective of connecting devices, NFC is also much faster than Bluetooth. As long as the smart device supports NFC, we only need to turn on the phone and touch the smart device to be used to connect directly. Isn’t it very convenient? In addition, NFC can also serve as our car key. However, only BMW, BYD and other models support this function.

The above points are very convenient for our lives. Currently, there are not many mobile phones that support NFC. Because in the real environment, the ecological environment that supports NFC has not been fully established, so the future development of this function will depend on the development of our own environment.
