With the continuous development of technology, Near Field Communication (NFC) technology has gradually penetrated into our daily life. From payment, transportation cards to access cards, NFC has brought us great convenience. In this article, we will take Huawei phones as an example to introduce how to enable NFC in detail, and share a practical tutorial on how to copy access cards with NFC on Huawei phones.
1. Confirm whether the phone supports NFC function.
First of all, we need to confirm whether our mobile phone supports NFC. Take Huawei mobile phones as an example, we can check from the top drop-down menu to see if there is an icon with a double N logo, if there is, then congratulations, your phone supports NFC function. In addition, we can also check whether there is an NFC switch through "Settings" More Connections to further confirm whether the phone supports NFC function.
2. Turn on the NFC switch.
After confirming that your phone supports NFC, the next step is to turn on the NFC switch. Make sure your phone is connected to the internet and follow these steps:
Enter the "Settings" interface of your phone;
Find and tap on the "More Connections" option;
In the "More Connections" page, find the "NFC" option and click to enter;
Turn on the "NFC" switch, and at this time, the NFC function of the mobile phone has been successfully turned on.
3. How to copy the access control card for NFC of Huawei mobile phones.
With the improvement of community security, more and more communities are equipped with access card systems. However, carrying a whole bunch of access cards can be cumbersome and take up space. Luckily, if your Huawei phone supports NFC, you can easily copy the access card to your phone for one-piece access.
Here is the detailed tutorial:
Confirm that the phone supports the NFC function and has turned on the NFC switch (as mentioned earlier);
Open the Wallet app on your HUAWEI phone, log in to your HUAWEI ID, and go to the home page.
In the "Wallet" home page, find and click on the "Wallet" option;
Once you are on the "Card Pack" page, click on the "Add" button at the bottom and select the "Door Key" option;
In the "Door Key" page, select the "Access Card" option and click on "Simulate Physical Access Card";
At this time, please attach your physical access card to the NFC sensing area on the back of the mobile phone to let the mobile phone identify it;
After successful recognition, the mobile phone will automatically simulate the access control card. In this case, you need to enter your HUAWEI ID and password to confirm.
Edit the card information, such as the card name, card cover, etc., and then click the "Confirm" button;
Wait a few moments, and your phone will display a message that says "Write card successfully", at which point, you've successfully copied the access card to your phone.
It should be noted that the NFC copy access card function of Huawei mobile phones only supports some cards with a frequency of 1356MHz access card. If your access card doesn't meet the requirements, or if multiple attempts to simulate or swipe the card have failed, it's recommended to use the original physical access card.
4. Other application scenarios of NFC function.
In addition to copying access control cards, there are many other practical application scenarios for the NFC function of Huawei mobile phones. For example:
Transportation card: You can copy the transportation card information to your mobile phone, and when you take public transportation such as subway and bus, you only need to hold your mobile phone close to the card reader to complete the payment;
Payment: At merchants that support NFC payment, you can use your mobile phone to make payment operations directly, which is convenient and fast;
Data transfer: Two mobile phones that support NFC function can quickly transfer **, etc. files by "touching";
ID card recognition: Huawei phones in some regions also support reading ID card information into the phone for easy identity verification and other operations.
5. Summary and outlook.
Through the above introduction, I believe you have mastered how to enable the NFC function of Huawei mobile phones and how to use NFC to copy access cards. NFC technology has brought great convenience to our lives, so that while we enjoy the convenient life brought by technology, we also look forward to more surprises for us in the future.
