Three basic types of NFC applications

NFC as a popular near field communication technology in recent years, its application is very wide. NFC applications can be roughly divided into three basic types, the following let me bring you closer to the three basic types of NFC applications.

1.Payment Application

NFC payment application mainly refers to the application of cell phone with NFC function to simulate bank card, one card and so on. And NFC payment applications can be divided into two parts: open-loop applications and closed-loop applications.

The application of NFC virtualized as a bank card is called an open-loop application. Ideally, the cell phone with NFC function and added simulated bank card can be used as a bank card in supermarkets, shopping malls, POS machines for cell phone consumption. However, at present, it cannot be fully realized in China, mainly because NFC payment as an open-loop application has a complicated industrial chain, behind which the interests of card vendors, programmers and the industrial pattern of the game are very complicated. On the current domestic NFC open-loop application of the environment, due to the interests of the game, NFC open-loop payment applications have missed the best time before the popularization of Alipay and WeChat Pay and other mobile payments, NFC open-loop payment is extremely difficult to develop alone. Its development can only seek to connect and bundle with Alipay and WeChat Pay, as a means to assist Alipay and WeChat Pay for identity authentication, before it is possible to occupy a place in the future of mobile payment. (Currently bundled)

The application of NFC to simulate a card is called closed-loop application. At present, the closed-loop application of NFC in the domestic development is not very satisfactory, although the public transportation system in some cities has opened the NFC function of cell phones, but it has not been popularized. The fundamental reason is that the card as a carrier of the card system exists to issue cards for profit. System integrators and operators (public transportation groups and schools, etc.) in the issuance of cards can make huge profits. Thus, millet and other cell phone companies in some cities, although the pilot opened a cell phone NFC bus card function, but generally still need to open the service fee. But I believe that with the popularity of NFC cell phones and NFC technology continues to mature, a card system will gradually support the application of NFC cell phones, closed-loop applications will have a bright future.

2.Security applications

The application of NFC security is mainly to virtualize the cell phone into access card, electronic tickets, etc. NFC virtual access card is to write the existing access card data into the cell phone NFC, so that there is no need to use a smart card, the use of the cell phone with NFC function block can realize the function of access control, NFC virtual electronic tickets is the application of NFC virtual tickets is in the user to buy a ticket, ticketing system will be sent to the cell phone ticket information with the NFC function of cell phone can be virtual ticket information into electronic tickets in the checking of tickets is directly brush the phone can. The application of NFC in security system is an important field of NFC application in the future, and the prospect is very broad. the application of NFC in this field not only saves the cost of operators, but also brings a lot of convenience to users. The use of cell phone virtual instead of physical access card or magnetic card type tickets can be reduced to a certain extent the production cost of the two, with the convenience of the user to open the card card operation, to a certain extent to improve the degree of automation, reduce the opening of the card personnel to employ funds and enhance the efficiency of the service.

3. Tag application

The application of NFC tag is to write some information into an NFC tag, and the user only needs to wave the NFC phone on the NFC tag to get the relevant information immediately. For example, merchants can put NFC tags containing posters, promotional information, and advertisements in front of their stores, and users can use their NFC-enabled cell phones to get relevant information according to their needs, and can log in to social networks, share details or goodies with friends.

In recent years, NFC (Near Field Communication) technology, as a convenient non-contact communication method, has shown a wide range of application prospects in many fields. According to different application scenarios, NFC technology can be mainly categorized into three main categories: payment applications, security applications and tag applications.

In terms of payment applications, NFC can be used to simulate both bank cards (open-loop applications) and city card (closed-loop applications). Although NFC payment has not yet been fully popularized in China due to the industrial chain interest game and the popularity of mobile payment (such as Alipay and WeChat Pay), its bundled cooperation with mainstream payment platforms still provides possibilities for its future development. In terms of security applications, NFC can be used for virtual access cards, e-ticketing, etc., which not only reduces operating costs, but also enhances the user experience, and has a broad prospect in the future in the fields of intelligent buildings and transportation ticketing. In terms of labeling applications, NFC tags can quickly deliver information and are suitable for commercial advertising, intelligent marketing and other scenarios, providing users with a convenient way of interaction.

Although the promotion of NFC technology in China still faces some challenges, such as industry chain integration, user habit cultivation, etc., with the popularization of NFC cell phones and the continuous maturity of the technology, its application potential in mobile payment, intelligent security, Internet of Things and other fields will be gradually released. In the future, NFC is expected to combine with 5G, AI and other technologies to further expand application scenarios and become one of the important supporting technologies for smart cities and digital life.
