What is the function of NFC on the phone?

If you're currently using a Vivo phone, NFC provides a simple, touch-based solution for short-field wireless communication between mobile devices, consumer electronics, PCs, and smart control tools.

Make it simple and intuitive for consumers to exchange information and access content and services. And the NFC function can be used without the assistance of other accessories.

NFC is the abbreviation of Near Field Communication, that is, Near Field Communication Technology. Developed by Philips and Sony, NFC is a contactless identification and connectivity technology that enables short-range wireless communication between mobile devices, consumer electronics, PCs and smart control tools.

The role of NFC:

1. It can be used as a bus subway card.

After having a mobile phone with NFC function, you can directly turn on the function of the local subway and bus on your mobile phone, so that you can use the NFC of the mobile phone to swipe it, and you don't need to remember to bring the bus card when you go out, and the mobile phone can also meet our needs.

2. Recharge the bus metro card directly.

After having NFC, you can directly fit the back of the subway bus card and the mobile phone together, so that you can use the Alipay software and WeChat payment that are usually used for consumption in the mobile phone, and directly recharge the bus and subway card, anytime, anywhere, and without queuing, saving a lot of trouble.

3. When the access card of the gate is used.

You only need to click on the virtual in the door key in the mobile phone, and then put the access card on the back of the mobile phone to read, and after entering the relevant information, we can directly act as the access control card through the NFC of the mobile phone, and no longer worry about the embarrassing situation that your access control card forgets to carry.

4. Connect the Bluetooth speaker to NFC.

Now there are many Bluetooth speakers on the market that are also equipped with NFC function, when we connect, we only need to use a mobile phone that supports NFC function to touch it, and you can turn on the Bluetooth speaker, which is much more convenient than we need to set up Bluetooth pairing connection before, especially easy to use.

Mobile NFC is a short-range wireless technology.

Nowadays, more and more mobile phones support NFC function. Of course, many people don't know what the NFC really is. Near-field communication (NFC) is a short-range wireless technology. NFC has functions such as mobile payment, data transmission, information browsing, and access control.

It provides a simple, touch-sensitive solution for exchanging information, accessing content, and services simply and intuitively. At the same time, NFC has the characteristics of low cost, easy to use, and more intuitive, making it more potential in some fields.

NFC Application Mode:

NFC devices can be used as contactless smart cards, write read terminals, and device-to-device data transfer paths. It has a wide range of applications and can be divided into three basic types:

Close Done. For apps like access control or ticket checking for traffic events, users can simply hold the device where the ticket or access is stored close to the reader. It can also be used for simple data capture applications, such as reading URLs from smart tags on posters.

Close Confirm. In apps like mobile payments, users must enter a password to confirm a transaction, or only accept a transaction.

If you're currently using a Vivo phone, 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.

How to operate the NFC transfer function:

1. Go to Settings - Other Networks and Connections More Settings - NFC Turn on the NFC switches of the two mobile phones; Note: (If there is no switch, it means that the model does not support NFC);

2. The two mobile phones are close to each other back to back (the NFC chip is on the right side of the camera on the back of the machine), when the NFC chip detects other devices, the mobile phone will have sound and vibration prompts, and the screen will shrink at the same time;

3. The mobile phone that is touched first is the sender, and the files received by the receiver are stored in the NFC folder under the USB flash drive of the mobile phone.

It is a quick payment feature.

Sometimes when we take the bus or go to the supermarket to buy something, we need to pay quickly, so we use the NFC function.

Super handy features.

The NFC function on mobile phones, or near-field transmission, is a short-range, high-frequency wireless communication technology that enables back-to-back data transmission between electronic devices.

Mobile NFC is a short-range wireless communication technology.

Near Field Communication (NFC) is an emerging technology that allows devices (e.g. mobile**) to exchange data in close proximity to each other.

It is evolved from the integration of contactless radio frequency identification (RFID) and interconnection technology, and integrates the functions of inductive card reader, inductive card and peer-to-peer communication on a single chip, and uses mobile terminals to realize mobile payment, electronic ticketing, access control, mobile identification, anti-counterfeiting and other applications.

Technical background

According to relevant information, around 2003, Sony (Sony) and the then Philips Semiconductor (now NXP Semiconductor) cooperated, planning to develop a more secure and compatible wireless communication technology based on contactless radio frequency card technology.

After several months of research and development, the two parties jointly released a wireless communication technology compatible with the IS014443 contactless card protocol, named NFC (Near Field Communication), and the specific communication specification is called NFCIP-1 specification.

Shortly after the release of the NFC technology, both parties submitted a draft standard to the European Computer Manufacturers Association (ECMA) as a near-field communication standard and was quickly recognized as a standard, followed by an application to ISO IEC with the help of ECMA, which was eventually recognized as ISO IECL8092.
