Recently, there is a message that the millet phone supports the function of swiping the door. The swiping card makes things that we do everyday, but we sometimes forget to bring the bus card with the bus. Sometimes we forget the card with an access card. When it will be very embarrassing, and millet phone this function is a very good solution to this problem. Although the function looks very simple, but she needs the support of mobile hardware and software at the same time to achieve the effect.And the hardware NFC is a very important function.In fact, the mobile phone NFC and Bluetooth, flight mode, WiFi hotspot and other functions Similarly, we usually do not think of the use of mobile phones, but it is an indispensable feature of mobile phones. Since talking to NFC, then we talk about it today.In fact, NFC already exists before the emergence of smart phones, is short for Near Field Communication (Near Field Communication), as the name suggests it is a short-range wireless communication technology. Technology evolved from contactless radio frequency identification (RFID). In 2004 Philips, Nokia and Sony co-developed and launched the NFC Forum to begin commercializing NFC technology based on RFID and interconnect technologies, with active and Passive two read modes.  NFC mainly card mode, point to point mode and card reader mode three working modes, most of the scenes we are using the first two .Card mode and point-to-point mode, card mode is rarely used. Card mode is Currently used the most widely used scenario, the above-mentioned mobile phone is to use this mode, it is equivalent to an IC card using RFID (non-contact radio frequency identification) technology, you can in the mall, bus , Access control and other occasions to replace the IC card or credit card, such as we often use the phone to pay on POS machines also use the card mode, it does not require mobile phones and POS contacts, just close to the payment, this time is to replace our credit card Wait;  The point-to-point mode, the main user data exchange, that is, when we usually transfer data between two mobile phones will be close to two NFC-enabled phones, and then transfer its biggest drawback is undoubtedly the short transmission distance, while a bit is the connection speed and NFC is also much like Bluetooth, both are short-range communication technologies, and compared to NFC, the biggest advantage of Bluetooth is undoubtedly the transmission distance farther, in addition to the Bluetooth data transfer than Bluetooth Larger, in addition to transfer faster. The reader mode application scenarios such as posters or exhibition information on the electronic label to read the relevant information, the scene is less, we usually use less than usual. Although we can not see the existence of NFC both in the phone appearance and in the system, it has a lot of uses in our daily life. It can be said that our life is inseparable from this little NFC, and Not just the lives of each of us, but also the widespread use of NFC by governments, businesses and others. 1, mobile payment Nowadays, we are accustomed to go out every day without a wallet, go to the supermarket to shop, eat in restaurants and so on through WeChat or Alipay code scanning, and in addition to WeChat / Alipay code scanning, the use of POS payment is also a more common form of payment, and Mentioned earlier, the use of POS payment will use NFC.
In terms of mobile phone NFC payment, UnionPay is the absolute supporter. In December 2015, China UnionPay formally launched the 'cloud flash payment' product jointly with more than 20 commercial banks. After a week, CUP announced its cooperation with Apple and Samsung. In 2014, Apple released the latest version of iPhone in addition to the latest iPhone release, but also released Apple Pay, an Apple mobile payment solution, while Apple Pay used NFC. Apple Pay officially launched in the United States on December 20, 2016 Samsung launches Samsung Pay, MiMay launches XiaWei, and Huawei PayPal Huawei Pay. Both of these payments are made via mobile NFC. 2, traffic credit card We usually see many people in the bus, the subway is not a brush card, but the phone directly on the gate or swipe card, you can pass, which is achieved through the mobile phone NFC, in fact, we usually use the bus A card is an NFC chip, so a mobile phone with a support function can pay on a transit bus instead of a bus card. NFC mobile phone credit card compared to the ordinary card also has many convenient places, first of all, is no longer have to worry about forgotten with traffic card or traffic card is lost, because everyone is bound to go out with the phone, and the chances of forgetting to bring is very small , So it is not afraid to appear to the subway or other bus came to forget the embarrassment of forgetting to take the bus card; secondly, you can recharge the bus card directly on the phone to avoid the trouble of queuing to pay; again you can view the bus card in real time balance. 3, data transmission Data transmission, mentioned earlier mentioned point to point mode.There are relatively few data transmission functions of NFC at present, among them the most important reason is not bluetooth, but WiFi. In the past two years, the WiFi coverage area has been very wide, and even without WiFi, traffic costs are not as expensive as before. It is still acceptable to transmit some pictures, files and songs, and APPs like WeChat and QQ , But also allows people to choose between the two when the first choice of data transmission, rather than NFC or Bluetooth. The most important thing is that without the need to consider distance limitations with WiFi transmission, and transmission of the parties do not even need to be online at the same time, Both sides of the transmission data get rid of the limitation of time and space, and the main reason that the time and space formally limit the popularity of NFC and Bluetooth data transmission. The NFC data transfer is actually very simple way, the back of two phones back to back paste together (aligned to the two phones NFC area), and then is the choice you want to transfer the content can be. 4, brush the door card Mentioned at the beginning of the article, millet phone support brush card, for people who are easy to lose, this feature can really be said to be very help-free. 5, read the information The main function of the previous use of the NFC card is the card mode and point-to-point mode, but also the most widely used NFC features, and NFC there is a third mode: card reader mode. In this mode, the read-write NFC mobile phone can collect data from the TAG and then process it according to the application requirements.Some applications can be completed locally, while others need to interact with the network to complete.Typical Applications include electronic advertisement reading and ticket cinema ticket sales, etc. For example, a TAG tag affixed to the back of a movie poster or exhibition message may be used by the user for details or a credit card purchase online immediately. In addition, But also get bus station site information, bus maps and other information. In addition to the above functions, NFC-enabled handsets are connected to NFC-enabled devices. For example, some Bluetooth-enabled speakers can be connected to the handset via NFC and can be directly connected to the corresponding printer to print photos directly from the handset. In this era of mobile internet, some functions of NFC are gradually weakened, such as data transmission, information reading and mobile payment, while some functions are getting closer and closer to our life, such as bus credit card swiping, Development, NFC will be changed, but the moment, is the best state.
