NFC Application

With the popularization of mobile payment, people's clothing, food, housing and transportation can be solved through a mobile phone, which greatly improves the efficiency of people's work and travel.

 In the first half of 2017, Alipay and WeChat Pay jointly won over 90% of the transaction share in the mobile payment market. The popularity of QR code payments indicates that the mobile payment market is mature.

   QR code payment has quickly occupied the payment market, and it is used in all aspects of our lives, bringing convenience, and its disadvantages have gradually appeared. For example, cumbersome payment methods will result in a large number of queues, low security factor, easy to be stolen information, payment environment must have a good network, etc. The damage of the QR code will also affect our payment and travel experience.

   Therefore, people began to seek more convenient and secure payment methods, so they were born at the same time as QR codes. NFC, which was prepared as an information transmission and upgrading requirement, re-entered the public's vision and gradually became known.

  Using mobile phones with NFC function, you can pay directly by sticking the back of the mobile phone to the location where you need to pay, or you can directly use it as an access card to quickly pass through the security channel. Its quick and convenient features directly hit the drawbacks of QR code application. In terms of payment, it is not necessary to go through the network, and it can be directly brushed without information leakage. It can be said that it is the first choice to replace the QR code as a mature and secure payment method.

  In fact, NFC technology appeared as early as 2003. At that time, Philips and Sony planned to develop a compatible wireless communication technology based on contactless card technology. Philips sent a team to Japan to work with Sony engineers to start developing this technology. Three months later, the two companies jointly released research and development results, which is a wireless communication technology compatible with the current ISO14443 contactless card protocol, and named NFC (Near Field CommunicaTIon).

NFC (Near Field CommunicaTIon), also known as short-range wireless communication, is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission (within ten centimeters) to exchange data between electronic devices . This technology evolved from contactless radio frequency identification (RFID) and is backward compatible with RFID.

  Like RFID, NFC information is also transmitted by electromagnetic induction coupling in the wireless frequency part of the spectrum. NFC and RFID look very similar at the physical level, but in fact are two completely different fields, because RFID is essentially an identification technology, and NFC is a communication technology. NFC exchanges data through non-contact point-to-point data transmission (within ten centimeters) between devices. This mode is similar to infrared, and can be used for data exchange, but the transmission distance is shorter, the transmission creation speed is faster, the transmission speed is faster, and the power consumption is low.

When NFC came out, it had high hopes and had certain development abroad, but because smartphones were not popular at that time, and the corresponding software and hardware needed to be installed, the transmission protocol did not reach consensus, and the transmission speed could not be met. Now people's needs are gradually forgotten.

  Now that the Internet and smartphones have become popular, NFC's data transmission function is no longer the focus, and it has been gradually applied in many fields.

   1. Financial payment


  Mobile phone = bank card. It can realize the flash payment function of today's bank cards, but in order to use offline payment more efficiently, various manufacturers have added wallet functions to mobile phones, through NFC functions such as Apple Pay, Samsung Pay, Mi Pay, etc. You can pay directly with your mobile phone.

   2. Transportation

Traffic can be said to be the most basic function of NFC applications. By touching the card reading area of the gate of the NFC device, the gate can be automatically opened. This is to integrate the function of the urban traffic card onto the NFC device and realize it by card simulation. . NFC can help the transportation system improve the efficiency by an order of magnitude, and the support of the transportation system for NFC will also promote NFC, making it a basic framework for completing a good ecosystem.

  3. Label

  NFC tags have contact applications, which are similar to RFID applications, such as cell access cards, but this is less common on mobile phones. There is also a kind of contact browsing, which is mainly used to identify and track objects with NFC information, such as Nintendo 3DS game consoles. Recognizing amiibo mobile devices through NFC will display the corresponding content on the screen. amiibo mobile devices are an NFC tag In addition, some NFC electronic tags can be written with simple instructions for activating the specified functions on the mobile phone, such as writing a command to switch the silent mode on the tag. When the tag is close to the mobile phone, the mobile phone will automatically enter mute.

   4. Communication

  NFC inherits RFID The existing functions of human-computer interaction, machine-to-machine interaction, etc. will all go out of professional factory applications and move into people's daily home appliances, so that people can easily control household appliances. Nowadays, more NFC home appliance applications include NFC digital cameras and NFC smart TVs, and NFC mobile phones needlessly become the most commonly used electronic devices in people's daily lives. With the rise of the concept of the Internet of Things, NFC will gradually enter people's lives. .

   5. Retailer Super

The application of NFC in retail takes the French Casino supermarket as an example. In October 2012, the French Casino supermarket chain announced the pilot of the world’s first NFC supermarket. In the supermarket, the user reads the NFC tag of the goods on the shelf through the NFC mobile phone, and then the customer The NFC mobile phone will display the product's ingredient list, supply information, video information, price and other related information, and the supermarket can read the number of tags to understand consumer preferences, and further arrange the humanized placement of shelves to promote consumption. At the same time, it can be combined with a virtual APP to increase or decrease the products purchased, so that consumers can see the products they have purchased at a glance, and know the amount of consumption in advance, and NFC payment also has a combination of applications.

   6. Safety traceability system

  The NFC relief rental system launched by the Ministry of Science and Technology of Korea. After downloading the APP of the system, passengers can scan the NFC tag in the car to obtain the license plate number, driver number, driver name, contact information, and section of the taxi. Passengers can send the letter to family members or relatives and friends by text message. Just swiping the label can add a peace of mind for night travel, so that family members and friends no longer have to wait in fear. Today's frequent taxi-hailing software is not as good as the NFC system in South Korea, which can match the corresponding NFC rental system, so the safety factor of shared travel will be greatly improved!

   7. Advertising interaction

  Use NFC tags for advertising interaction, which has been used as early as 2012, and Australia promotes its latest Halo 4 game. The posters have NFC tags and QR codes, which are complementary in two ways, and the biggest feature of this activity is that the first player to read the NFC tag can get a unique reward, and subsequent readers can only get the basic Promotional content, this method of promotion can arouse players' treasure-hunting enthusiasm, and the city searches for NFC advertisements for the first reading reward. In addition, the deep browsing of advertisements has also been strengthened a lot, and it is also the perfect combination of online and offline, virtual and real activities.

   8. Book publishing

   For books, there has always been a controversy about whether electronic books will replace paper books, and now the arrival of NFC technology will also change the original mode of book publishing. In October 2012, Albuquerque, New Mexico, USA launched the NFC book at the Hot Air Balloon Festival. The book integrates eight NFC chips, which can be read through NFC devices to browse multimedia, interactivity, infotainment, personalization, social media, etc. It can be added, so it can bring a different reading experience, especially after the addition of videos, games, and social functions, paper books have become colorful. Publishing can be more than just books. NFC can also be used on CDs. The first is the prevention of piracy. Although QR codes also have certain anti-counterfeiting features, they are too reproducible and difficult to match NFC in security.

   Apple/Huawei/Xiaomi/Samsung and other brands of mobile phones gradually use the NFC function as a standard. The latest iPhone XS, iPhone XS Max, and iPhone XR all use NFC payment as a continuing payment method, and they also support NFC payment without apps. NFC technology will be more widely applied to all aspects of the people's clothing, food, housing and transportation. New trends in the development of the NFC industry.

  NFC retail inspiration

   The wave of new retail has made traditional retailers aware of the impact of technology on the retail industry. There is no traffic in offline stores for retailers, but there is no conversion after the transformation and acquisition of traffic. The embarrassing situation of hiring a professional operation team to convert traffic but unable to effectively interact with fans has led to a large amount of traffic earned by fans and fans unable to survive.

  NFC tag function can effectively interact, and can also push soft and wide during the interaction; food can not only be traced safely, but also obtain more effective information in the digital transformation. NFC's mobile payment function can greatly improve the checkout efficiency, and also take into account the access control system, and it can also earn a world in unmanned stores and unmanned containers.

   The previous Weibo war made Weibo and Tencent invest a lot of money, but failed to shake Weibo's position and market. It was not another Weibo that stopped the Weibo war, but WeChat. Then the communication function of NFC cannot be used in the wireless field. It may be possible to work hard in the new retail field of the mobile payment era, and NFC applications other than payment will definitely be more and more in the future.
