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. Mobile phones that use NFC technology can exchange data when they are close to each other, and use mobile terminals to implement mobile payment, electronic ticketing, access control, and mobile identification. , anti-counterfeiting and other applications.
However, in daily life, people usually only use NFC to brush bus cards. They rarely use or even know about other functions. Actually, it has many practical functions.
Transfiguration bank card
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.
Credit card payment can be made
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. Learn the information of the access control card through the mobile phone and record it on the mobile phone so that you only need to directly swipe the mobile phone when you go home.
Can serve as a door guard
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.
Can be transmitted to each other as a file
The above is the function of NFC besides serving as a bus card. What do you know about functions? Have you started using these features?
