Where can I use the NFC function of my mobile phone now?

If you are currently using a vivo mobile phone, how to turn on NFC: go to Settings - Other Networks and Connections More Settings - Turn on the NFC switch. (If this switch is not available, it means that the model does not support NFC).

1. How to open a vivo pay transportation card: enter vivo wallet - click "transportation card" - activate it now - select a city or transportation card - open it;

2. How to activate vivo pay: You can add a vivo pay bank card on the home page of the wallet -- vivo pay -- install the UnionPay security plug-in -- and follow the instructions for opening a vivo pay bank card.

3. How to add NFC access card:

Then go to the vivo wallet - access card page, and select the type of card you need to open;

Hold the non-encrypted physical access card close to the NFC antenna of the mobile phone to read the card;

Complete the authentication and write the card according to the prompts on the page to add the access control card.

Note: Since the display is the default last used card, if the last time you used the bus card, then you need to manually select the access control card, vivo pay access control card when in use, you can automatically wake up the door key interface by double-clicking the power button or close to the access control card machine, select the access control card you need to use, and close the NFC antenna to the card sensing area to unlock the lock. (The unlock does not need to be fully attached to the credit card machine, so it is easier to unlock the unlock by ensuring that the NFC antenna is close to the credit card machine.)

Note: NFC provides a simple, touch-based solution for short-range wireless communication between mobile devices, consumer electronics, PCs, and smart control tools, allowing consumers to exchange information, content, and services simply and intuitively. And the NFC function can be used without the assistance of other accessories.

Mobile phone NFC is not a novel function, as early as seven or eight years ago, when smartphones were just becoming popular, NFC has become the standard configuration of many flagship mobile phones, and its use scenarios are mainly as follows: 1. Quickly connect Bluetooth devices. Traditional Bluetooth devices need to be connected to smartphones through a pairing code, which is inconvenient to operate.

After using the NFC function, the mobile phone and the Bluetooth device only need to be touched once, and the pairing can be quickly completed, and the mobile phone does not even need to be unlocked, which greatly simplifies the connection steps between the Bluetooth device and the smartphone.

2. Use tags to switch between scenario modes. NFC tags are special cards with a coil in between, which can be used to help mobile phones quickly switch between story modes. For example, you can stick a "mute" tag on your work, and put your phone on the title to automatically switch to silent mode.

Similarly, if you place your phone on the "Ring" tab in your home, it will automatically switch to ring mode. Users can make NFC tags with different functions according to their actual needs, and can quickly switch between scenario modes without unlocking the phone. 3. Transmit data in close proximity.

Two NFC-enabled devices can be attached together to transfer files such as **, **, **, etc. Although NFC is slow and not as fast as Bluetooth, it is still used in some cases. 4. Take public transportation.

NFC's communication standards and RFID (Contactless Radio Frequency Identification.

Very similar, so most bus system readers.

Both can recognize the NFC chip of the mobile phone, so the smartphone can also replace the bus card and swipe the card to take the bus at the bus and subway station.

5. Recharge the bus card. Most smartphones have NFC that supports read-write functions, and software such as Alipay can be used as a card writer to write data to the bus card. In this way, there is no need to go to a special recharge point to recharge the bus card. 6. Mobile payment.

Similar to the function of the bus card, the NFC chip of the mobile phone can also be recognized by the POS machine of supermarkets and stores, and the NFC chip bound to the bank card can replace the bank card and pay directly on the POS machine. However, it must support UnionPay QuickPass.

The POS machine can read the NFC chip of the mobile phone, and the POS does not have this function when the old-fashioned card is swiped.

7. Simulated access control card.

The access card can be copied into the NFC chip, so as to realize the replacement of the access card with a mobile phone. However, there are only a limited number of access cards supported by this function, and the encrypted access card cannot be copied, so there are not many access cards that can be copied to the mobile phone. In fact, NFC is the most practical way to use it as a bus card to take public transportation, or to replace bank cards for mobile payment.

If the demand for this aspect is not very large, whether the mobile phone has NFC function or not does not affect the daily use experience.

What I use the most is the bus and subway card, you can also swipe the bank card, swipe the door card, the current contact is these, I personally think it is very convenient, go out without a bunch of cards alone.

It can be used to recharge the bus card, I think these functions are very difficult to use, because we don't need them, and now it is the era of mobile phone payment.

Access card when you come to work. Swipe your card when you take the bus or subway. Access to the home. As well as some commonly used social functional cards can be imitated by NFC functions. But the main thing is to see if the technology supports it.

5. After the gray button turns into a blue button, it proves that the NFC function of the mobile phone is successfully enabled.

That's it for the introduction of the NFC function of mobile phones.

NFC, also known as Near Field Communication, is a short-range, high-frequency wireless communication technology that allows contactless point-to-point data transmission (within ten centimeters) of data exchange between electronic devices. For example, it can be used to brush the subway bus, etc.

You can turn on NFC by doing any of the following:

1.Swipe down from the status bar to the notification panel (to continue scrolling) and light up NFC. Press and hold to enter the NFC settings interface.

In layman's terms, NFC is a service that can be enjoyed with the simplest touch of a button, which requires more complex operations. After binding the relevant things, you can use the NFC function of the mobile phone to pay for ordinary consumption and services related to card swiping. NFC is one of the latest products of modern scientific and technological progress, and it has brought many conveniences to people's lives.

In layman's terms, NFC is the simplest way to use touch, which is to make it easier for consumers to access information and bring convenience to other aspects of life. By touch. The exchange of information can be done in a matter of seconds, which is much easier than using a mobile phone.

People can use it to make payments, swipe cards, identify cards.

It is believed that in the future development of science and technology, the functions of NFC will become more and more complete, and its related vulnerabilities will be improved in time. Nowadays, whether it is a ** mobile phone or a mobile phone on the market before, there is still an NFC function in the mobile phone, I believe that everyone will like this function very much after trying it.

"NFC is a wireless connection technology that provides easy, safe and fast communication, and its transmission range is smaller than that of RFID, which can reach several meters or even tens of meters, but because NFC adopts a unique signal attenuation technology, NFC has the characteristics of short distance, high bandwidth and low energy consumption compared to RFID.

Before learning to use this feature, we need to have a mobile phone with NFC function, and most smartphones nowadays have this function. We have to go to the phone's settings to turn on this function, and this function will generally be turned off by default.

The few upstairs aren't xt5, right?XT5's NFC has only one function, which is to quickly link Bluetooth, and the NFC on the NFC and Bluetooth touch on the NFC on the car without pairing, and it will automatically help you configure it.
