What does nfc mean?

Bus cards are used to swipe cards, access cards are used to swipe cards, K cards are used to swipe cards, fitness cards are used to swipe cards, shopping malls use bank cards or credit cards to swipe cards, and medical insurance cards are used to swipe cards when they are sick ... 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.

First of all, we should simulate the NFC mobile phone as a card, which is a blank card without any application, that is, we can't use it to swipe the card. If you want to download an application, you can swipe your card. For example, if you download a bus application, you can swipe your bus card. You can swipe the access card by downloading the access control application; Download the bank's application and you can swipe your bank card and so on. The key is how to download the application. There are two ways:

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!

What does NFC mean?

NFC near field communication technology 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. The working frequency is 13.56MHz, but users who use this mobile payment scheme must change their dedicated mobile phones. This technology is widely used in Japan and South Korea. Mobile phone users can travel all over the country with mobile phones with payment function: their mobile phones can be used as airport boarding verification, building access keys, transportation cards, credit cards, payment cards and so on.

What does NFC mean? What's the role?

What is the NFC function?

Before explaining what NFC function is, let's talk about what NFC is. In fact, NFC is a near-field communication technology, which is the near-field communication technology to put it bluntly. NFC can carry out near-field communication among mobile devices, consumer electronic products and other tools, and can directly exchange information and access content.

At present, NFC on many smart phones can only be used for image exchange and other operations. Because NFC is not popular enough, it is estimated that it will take some time to realize the vision of using NFC as an electronic wallet.

How to use the NFC function of mobile phone?

Next, the security engineer of Great Shield will tell you what functions NFC may have in the future. At present, NFC devices are mainly used for mobile phone applications. At present, NFC technology is mainly used in the following five categories.

1. Contact passes, such as access control, tickets, etc. Users only need to store tickets or access control passwords near the card reader, which can also be used for logistics management.

2. Contact payment, such as contactless mobile payment, allows users to pay by placing the device near the POS machine embedded with NFC module and confirm the transaction.

3. Contact connection, such as connecting two NFC devices for point-to-point data transmission, such as downloading music, exchanging pictures and exchanging address books.

4. Contact browsing, users can connect NFC phones to smart public telephones or street posters with NFC functions to browse traffic information.

5. Download contacts, users can receive or download information through GPRS network for payment, access control and other functions. As mentioned above, users can send short messages in a specific format to the domestic helper's mobile phone to control the authority of the domestic helper to enter and leave the house.

Does anyone know what NFC means?

Near field communication (NFC), also known as near field communication, is a short-distance high-frequency wireless communication technology, which allows non-contact point-to-point data transmission between electronic devices (within ten centimeters) to exchange data. This technology evolved from contactless radio frequency identification (RFID). The backward compatible RFID first developed by Sony and Philips is mainly used to provide M2M(Machio Machine) communication in handheld devices such as mobile phones. Due to the natural security of near-field communication, NFC technology is considered to have great application prospects in mobile payment and other fields.

What is the nfc function?

If I tell you directly what the nfc function is, many friends don't quite understand it. Here are two examples to let you feel the charm of nfc function and let you know what nfc function is and how to use it.

Case 1: Samsung uses NFC to push the Holiday Inn Service app.

NFC Samsung hotel service

The NFC function on smart phone can not only do simple wireless electronic payment, close contact with connected devices, but also do something that could not be done before. Short-range wireless technology (NFC near field communication) expands the new way of payment and shopping itself. Now it seems that it can help you open the door.

NFC smart phone using secure network connection and mobile network can be said to be an ideal key.

Among the keys we have used for a long time, keys have two important properties. First of all, the function of the key is to unlock, so that objects that are locked continuously can gain access. Secondly, the key means that the key holder has authority, which is why we need to ensure the safety of the key. The electronic key changed all this. Nowadays, the electronic key can well identify the key holder with permission. Now the peak of this technology appears on smart phones, such as Samsung mobile phones, which will provide new services for NFC during the London Olympic Games. It launched a hotel service solution designed for Holiday Inn London Statford Branch. Through the dedicated app of Galaxy SIII mobile phone, tenants can check in and check out, and can use the NFC function of the mobile phone to open the room door.

This way of opening the door is smart enough to use the tenant's mobile phone holding and security protocol to identify whether the owner has the right to open the door. You don't even need to bring an extra key to hold a mobile phone. Just like you use a low-tech room card, once you work overtime in the hotel, it will automatically cancel your authorization to use your mobile phone to enter the hotel facilities. Also, during the Olympic Games, this special app will also provide tenants with localized content, including Olympic information of competition results. Not only that, this app can also control the TV, lighting, air conditioning and other electrical appliances in the hotel, and provide preferential information according to the location of the guests.

What does NFC mean when it appears on mobile phones?

It means that there are devices nearby that can exchange NFC data with mobile phones, such as bank cards.

NFC mobile phone refers to a mobile phone with NFC module. The mobile phone with NFC module can do many corresponding applications. NFC stands for near-field communication and is a short-range wireless communication technology.

2065438+On July 9, 2003/KLOC-0, China Mobile Beijing Company signed a cooperation agreement with Beijing Municipal Traffic Card Co., Ltd. to jointly release the application of "Mobile NFC Mobile Card".

From July 22nd, as long as you have a mobile phone supporting NFC function and install a special SIM card for NFC card, you can complete small payments such as bus, subway credit card and supermarket catering by swiping your mobile phone in Beijing.

Extended data

The appearance of NFC mobile phone is an improvement. "NFC is near-field communication, also known as near-field communication. It is a short-range high-frequency wireless communication technology that allows contactless point-to-point data transmission and data exchange between electronic devices." Some experts explained that due to the high security of NFC, this technology is considered to have great application prospects in mobile payment and other fields.

In a hotel in Taipei, guests can apply for a free NFC phone from the hotel during their stay. This mobile phone can replace the traditional room card in and out of the hotel access control system, and can also take public transportation instead of easycard or spend a small amount in convenience stores when going out. In 20 12, several hotels in Sweden and London made the same exploration.

However, due to the low penetration rate of NFC mobile phones, there are only six certified NFC mobile phones launched by Beijing Mobile this time, including Samsung I9308(S3), Samsung I9508(S4), HTC New One(802t), ZTE U807N, Huawei T8950N, Xiaomi 2A and other models.

special technology

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 starts near-field communication, also called the initiating device (master device), provides a radio frequency field (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 (slave device), does not need to generate 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.

technology application

Since July, 2004, NTT DoCoMo Company of Japan has launched the mobile wallet business based on contactless IC card, hoping to gradually replace all the things people put in their wallets with mobile wallets.

MOA service based on contactless IC card technology launched by South Korea's SK Tele company uses mobile phones and bank credit cards to allow users to use mobile phones for on-site payment services.
