What is the NFC function of mobile phones used for? How to use?

Simulate a contactless card, such as access control card, bank card, etc. Card simulation mode is mainly used in contactless mobile payment applications such as shopping malls and transportation. Users only need to bring their mobile phones close to the card reader and enter a password to confirm the transaction or directly receive the transaction. In this method, the card is powered through the RF domain of the contactless card reader, and the NFC device can still work even if there is no power. In this application mode, the NFC reading device collects data from the NFC mobile phone with TAG capability, and then transmits the data to the application processing system for processing. Typical applications based on this mode include local payment, access control, electronic ticket applications, etc. .

To use the NFC function, take Xiaomi mobile phone as an example, the specific steps are as follows:

1. On the home page of the mobile phone, find the "Settings" icon and click to enter.

2. In the options listed in the settings, find "More connection methods" and click to enter

3. There is an NFC module among the functions listed, turn on the NFC on your phone , appears to allow the phone to exchange data when in contact with other devices. After opening, some options at the bottom also change from gray to black.

4. When using NFC wallet, you can choose the default wallet. For example, you can set this option when using payment.

How to use the payment function of NFC mobile phones

Let me give you an example. When taking a bus, you use a bus card, when you enter the door, you use an access control card, and when you sing karaoke, you use a card. Membership cards, VIP cards are used for fitness cards, bank cards or credit cards are used for shopping mall purchases, and medical insurance cards are used to buy medicine when sick... It’s so annoying to have so many cards! How to integrate these cards into one card will be easy.

The emergence of NFC mobile phones will solve this problem. The question is, if we have an NFC phone in hand, how should we use it? As we all know, NFC mobile phones have three major functions: card mode, reading mode and point-to-point mode.

Card mode means that the NFC mobile phone simulates a card. After downloading the application, this card can be swiped for consumption. Reading mode means that the NFC mobile phone can read cards, such as reading the balance on a bank card, the balance of a bus card, etc. It can also be used as a POS machine.

Peer-to-peer mode means that two NFC mobile phones can exchange data. What I want to say now is how to use the card mode of NFC mobile phones to solve the above problems, that is, how to make our NFC mobile phones swipe cards.

One is to take your NFC phone to a bus service point, and the waiter will help you download it, and then you can use it on the bus. This is to download applications to NFC mobile phones through external readers.

The other is to use the NFC phone to download applications for itself. The difference between these two methods is that the former requires the antenna of the NFC phone, while the latter does not.

They are similar in that the communication protocols used are APDU instructions. Obviously, the way for NFC mobile phones to download applications for themselves is more convenient for consumers and also beneficial to businesses.

For example, a store puts its application online, consumers download the application to their mobile phones, and the mobile phones can go to the designated store to swipe their cards for consumption. For example, A is on a business trip and the local bus card cannot be used outside the city. What should I do? You can download the bus application of that city on the Internet and put it on your mobile phone, and then the mobile phone will have the function of swiping the bus card in that city! Very convenient! .

Just touch it to turn on the Bluetooth speaker, which is much more convenient than setting up a Bluetooth pairing connection before. It's particularly easy to use.

Extended information:

Technical principle of NFC:

The technical principle of near field communication is very simple. It can exchange data through active and passive modes.

In passive mode, the device that initiates near field communications, also known as the initiating device, provides a radio frequency field throughout the communication process. It can choose one of 106 kbps, 212 kbps or 424 kbps transmission speed to send data to another device. The other device, called the target device, does not have to generate the RF field but uses load modulation techniques to transmit the data back to the originating device at the same speed.

In active mode, both the initiating device and the target device generate their own radio frequency fields for communication.
