In recent years, NFC technology has attracted more and more attention, and the business developed based on NFC technology has gradually penetrated into all aspects of people’s lives. So why is NFC so popular?
The service based on NFC technology has a short transmission distance because the data transmission is mainly based on the frequency of 13.56MHz. In addition, the information transmission based on NFC technology belongs to trigger information transmission, and the information interaction time is very short, and many times in the operation process belong to the millisecond level. Therefore, according to the characteristics and advantages of NFC technology itself, the basic form of NFC service mainly has the following three characteristics.
(1) Short: the communication distance is short, and the communication distance based on NFC is generally within 10cm, which is generally within the reach of human hands.
(2) Frequency: as a short-range wireless communication technology, although it is not a new technology, it has been rapidly developed at home and abroad in the past two years, and NFC applications represented by mobile payment have gradually penetrated into People’s Daily life, so the use of NFC business will be more and more frequent.
(3) Fast: Information transmission based on NFC technology is triggered information transmission, although the transmission rate is not high, but often requires a very short time to complete the information interaction, so different from other communication services, NFC services need to be processed quickly.
Because NFC technology-based services have the characteristics of short operating distance, frequent operation and fast operation process, the limitations brought by NFC oriented services are as follows:
(1) Geographical limitations: NFC technology is short operating distance, mainly to establish point-to-point data transmission between devices, unlike ordinary wireless transmission need to establish a large range of transmission network, so each region can establish a relatively independent business system and transmission system, and from the existing NFC business status also proves this point, such as: The existing model of the bus system is that each city is relatively independent of the business system, and the city can not form intercommunication with the city.
(2) Industry limitations: The entry threshold of NFC business is low, and it is easy for various industries to establish an NFC system for a specific business according to their own needs, and conduct their own business operations. There is a lack of such uniform industry standards across industries, so there is also the issue of interoperability.
(3) Business diversity: For users themselves, NFC business is a good bridge to build users’ real life and virtual life, and users’ real life is often not restricted by regions and industries.
