NFC development background: near field communication, near field communication.
This is a wireless technology initiated by Philips and jointly promoted by famous manufacturers such as Nokia and Sony. Many companies, universities and users have established the Pan-European Union, and they are all developing the open architecture of NFC and promoting its application in mobile phones.
NFC is developed from the integration of contactless radio frequency identification (RFID) and internet technology. It integrates the functions of sensor card reader, sensor card and point-to-point on one chip, and can identify and exchange data with compatible devices in a short distance. This technology was originally a simple combination of RFID technology and network technology, but now it has evolved into a short-distance wireless communication technology, and its development trend is quite rapid.

What is the NFC function of mobile phone for? How to use it?
Simulate it into contactless cards, such as access cards, bank cards, etc. Card simulation mode is mainly used for contactless mobile payment applications such as shopping malls and transportation. Users only need to put their mobile phones near the card reader and enter the password to confirm the transaction or directly receive the transaction. In this way, the card is powered by the RF domain of the contactless card reader, and even the NFC device can work without power. In this application mode, NFC reader collects data from NFC mobile phone with tag function, and then transmits the data to the application processing system for processing. Typical applications based on this model include local payment, access control, electronic ticket application and so on.
The use of NFC function, taking Xiaomi mobile phone as an example, the specific steps are as follows:
1. On the main page of the mobile phone, find the "Settings" icon and click Enter.
2. Among the options listed in Settings, find More Connection Methods, and then click Enter.
3. There is an NFC module among the listed functions. Turn on the NFC of the mobile phone, and the display allows the mobile phone to exchange data when contacting other devices. After opening, some options at the bottom also change from gray to black.
4. When NFC uses wallet, you can choose the default wallet. For example, you can set this option when using payment.
5. Touch payment. Choose applications that can be paid in this way.
6, open the Android bean, this can be opened or not. Used to share content between two devices.
How to use the payment function of NFC mobile phone
Let me give you an example. I use bus card, access card at the door, membership card for singing K, VIP card for fitness, bank card or credit card for shopping malls, and medical insurance card for illness ... so many cards are annoying! How to integrate these cards into one card is easy.
The appearance of NFC mobile phone will solve this problem. The question is, if we have an NFC phone, how should we use it? As we all know, NFC mobile phones have three functions: card mode, reading mode and peer-to-peer mode.
Card mode is to simulate NFC mobile phone as a card. After downloading the application, this card can be used for credit card consumption. Reading mode means that NFC mobile phones can read cards, such as the balance on bank cards and bus cards, and can also be used as pos machines.
Peer-to-peer mode means that two NFC phones can exchange data. What I want to say now is how to use the card mode of NFC mobile phone to solve the above problems, that is, how to make our NFC mobile phone swipe the card.
One is to take the NFC phone to the bus service point, and the waiter will download it for you, and then you can use it on the bus. This is downloading an application to an NFC phone through an external reader.
The other is that NFC phones download applications themselves. The difference between these two methods is that the former needs to pass through the antenna of NFC mobile phone, while the latter does not.
They are similar in that the communication protocol used is APDU instruction. Obviously, the way NFC mobile phones download applications for themselves is more convenient for consumers and beneficial to businesses.
For example, a store puts its own application online, and consumers download the application to their mobile phones, which can swipe their cards at designated stores. For example, A is on a business trip in other places, and the local bus card cannot be used in other places. What should I do? You can download the bus application of that city online and put it on your mobile phone, and then this mobile phone will have the function of swiping the bus card of that city! It's extremely convenient to say! .
What is the NFC function on the mobile phone for?
NFC function: It can realize mobile payment, electronic ticketing, access control, mobile identification, anti-counterfeiting and other applications.

What are the functions and functions of NFC in mobile phones?
NFC stands for near-field communication and is a short-range wireless communication technology. NFC is a non-contact identification and interconnection technology jointly developed by Philips and Sony, which can be used for near-field communication between mobile devices, consumer electronics, PCs and intelligent control tools.
The role of NFC:
1, you can make a bus and subway card.
With the NFC-enabled mobile phone, you can directly turn on the local subway and bus functions on the mobile phone, so you can use the NFC of the mobile phone to brush it, and you don't have to remember to bring a bus card when you go out. Mobile phones can meet our needs.
2. Recharge the bus and subway card directly.
With NFC, the subway bus card can be directly attached to the back of the mobile phone, so that the subway bus card can be directly recharged anytime and anywhere with Alipay software and WeChat payment used in the mobile phone, without queuing, which saves a lot of trouble.
3. When using the access card of the gate.
Just click Virtual in the door key of the mobile phone, and then put the access card on the back of the mobile phone to read it. After inputting the relevant information, we can act as an access card directly through the NFC of the mobile phone, and we no longer have to worry about the embarrassing situation caused by forgetting to bring the access card.
4. Bluetooth speaker connected with NFC
Now there are many Bluetooth speakers on the market that are also equipped with NFC function. When we are connected, we can open the Bluetooth speaker with a touch of a mobile phone that supports NFC function, which is much more convenient than setting up Bluetooth pairing connection before, and it is especially easy to use.
Extended data:
Technical principle of NFC:
The technical principle of near field communication is very simple, and data can be exchanged in active and passive ways.
In passive mode, the device that initiates near-field communication (also called the initiating device) provides the RF field during the whole communication process. It can choose the transmission speed of 106 kbps, 2 12 kbps or 424 kbps to send data to another device. The other device, called the target device, does not need to generate an RF field, but uses load modulation technology to send data back to the initiating device at the same speed.
In active mode, both the initiating device and the target device must generate their own RF fields to communicate.

How to use the NFC function of mobile phone?
NFC is the abbreviation of English full name: Near Field Communication, which means "short-range wireless communication technology" in Chinese. It is a non-contact identification and interconnection technology jointly developed by Philips and Sony, which can be used for near-field communication between mobile devices, consumer electronic products, PCs and intelligent control tools. NFC provides a simple touch-sensitive solution that allows consumers to exchange information and access content and services simply and intuitively.
In order to promote the development and popularization of NFC, the industry has set up a non-profit standard organization-NFC Forum to promote the realization and standardization of NFC technology and ensure the cooperation between devices and services. At present, NFC Forum has hundreds of members around the world, including Sony, Phlips, LG, Motorola, NXP, NEC, Samsung, atoam and Intel, among which China members include China Mobile, Huawei, ZTE, Shanghai Tanya and Zheng Long, Taiwan Province Province.
The popular high-end flagship phones of various brands released at the end of 20 12 began to gradually add NFC function. For example, in the second half of 20 12, Samsung Note2 flagship mobile phones, Meizu MX2, Lumia 900, Lumia 820, Lumia 920, HTC One X 8X, OPPO Find 5, Sony LT26i, Lenovo K900, and Huawei Ascend D2 released at the latest CES show all have built-in NFC function, which is relatively easy to realize, mainly because an NFC chip module is built into the back case of the mobile phone.
At present, NFC devices are mainly used for mobile phone applications. At present, NFC technology is mainly used in the following five categories:
(1) explosive, such as access control, tickets, tickets. Users only need to put the equipment with tickets or access codes near the card reader, which can also be used for logistics management.
(2) Touch payment, such as non-contact mobile payment, where the user places the device near the POS machine embedded with NFC module and confirms the transaction to make payment.
(3) Touch connection, such as connecting two NFC devices for point-to-point data transmission, such as downloading music, exchanging pictures and exchanging address books.
