The mobile phone is now a must-have for the device. Payment, checking routes, watching news, sharing bicycles, etc. provide a lot of convenience for our lives, and of course, NFC function. When it comes to NFC, it is obviously not a new word. Many mobile phones now carry this feature. Even Apple phones have achieved NFC.

First of all, the author first describes what NFC is. NFC, or near field communication, is an emerging technology.

At present, many mobile phones can implement the functions of mobile phone swipes. For example, Huawei's "Huawei Wallet" and Xiaomi's "Millet Wallet" are all bank cards that are bound in the app. And can also be used in places without a network, which is a major advantage of NFC compared to QR codes.

Act as a door guard

To achieve this function, it is necessary to satisfy two points at the same time: 1. The mobile phone needs to have a “card learning” function; 2. The access control card has no encryption.

Mutual transmission of documents

Everyone knows that you can use Bluetooth to transfer files. Actually, NFC can also be used for Bluetooth transmission. As long as two NFC-enabled mobile phones open the NFC function, the back of the phone can be contacted on the second hand without pairing, which is faster and more convenient than Bluetooth. However, it is recommended to transfer some smaller files because of the limited transmission speed.
