Recently, Huawei's newly listed mate20 series mobile phones have added a variety of black technologies, which has refreshed our cognition. Among them, the ultra-large wide-angle Leica three cameras, in-screen fingerprint technology, 40w super fast charging and 15w wireless fast charging are even more fascinating! However, a variety of black technologies hidden in Huawei's mobile phones are still unknown. Let's share a very convenient black technology-mobile phone access card!
If your Huawei mobile phone has NFC function, congratulations, you don't need an access card when you go out. A mobile phone is enough, so chic. Let's see how it is realized!
1. First, we open the Huawei wallet that comes with the Huawei mobile phone.
2. Click the "door key" function.
3. Click "Add".
4. put the access card of the community on the back of the mobile phone to read the card.
5. Start reading the card, wait a moment, and stick the card on the back of the phone.
6. After reading the card successfully, select "Add".
7. Just select the card type as "Community".
In addition, if there is a smart door lock at home or the company's access control supports credit card swiping, you can also use this function to simulate credit card swiping with your mobile phone, so you can only bring one mobile phone when you go out! Huawei Wallet also supports adding mobile phone bus cards in many cities across the country, and you don't need to bring a bus card to take the bus! In addition, Huawei recently launched the "electronic identity" function, which has been used in many hotels and consumer places, and will gradually support the purchase of train tickets, air tickets and other scenarios in the future. Isn't it cool? And I believe that in the future, "one machine in hand, travel all over the world" will definitely come true!
The development of science and technology has greatly facilitated our life. I believe that more interesting and useful black technologies will appear in our lives in the future. Let's wait and see.
