In recent years, NFC technology has attracted more and more people’s attention, and services developed based on NFC technology have gradually penetrated all aspects of people’s lives. So, why is NFC technology so popular?
The business based on NFC information exchange time is very short, and many times in the operation process are in the logy is mainly based on the frequency of 13.56MHz because of the data transmission, the transmission distance is relatively short. Moreover, the information transmission based on NFC technology belongs to the triggered information transmission and the millisecond level.
Therefore, according to the characteristics and advantages of NFC technology itself, the basic form of NFC-oriented business mainly has the following three characteristics.
(1) Short: The communication distance is short. 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 developed rapidly at home and abroad in the past two years, and the NFC application represented by mobile payment has gradually penetrated people’s daily lives. In life, the use of NFC-oriented services will become more and more frequent.
(3) Fast: Information transmission based on NFC technology belongs to triggered information transmission. Although the transmission rate is not high, it is often required to complete information interaction in a short time. Therefore, it is different from other communication services. NFC services need to be fast handled.
RFID features: (-NFC is very suitable for anti-counterfeiting traceability applications)
1. Non-contact, easy to identify. The communication distance can be within a few meters (NFC mobile phones can be directly read by one-by-one).
2. Rewritable. Data can be written repeatedly.
3. High security. The built-in algorithm is difficult to copy, transform, and forge in batches.
4. Permeability. There are obscured objects, and the labels can be identified even when they are not visible. The labels are rich in forms, and the labels are used in various ways, for example, they can be embedded.
5. Batch read. Multiple tags can be recognized at the same time.
6 Durability. Dirt-resistant, vibration-resistant, suitable for various harsh environments.
It is precise because the NFC-based business has the characteristics of short operating distance, relatively frequent operation, and quick operation process, the limitations brought by the development of NFC-oriented services are as follows:
(1) Regional limitations: NFC technology has a short operating distance, mainly to establish a point-to-point data transmission between devices. Unlike ordinary wireless transmission, a large-scale transmission network needs to be established. Therefore, each region can establish relatively independent services. System and transmission system and the current status of NFC business just prove this point. For example, the current model of the public transportation system is a relatively independent business system in each city, and there is no intercommunication between cities.
(2) Industry limitations: NFC business entry barriers are low, and various industries can easily establish an NFC system for a specific business according to their own needs and conduct business operations on their own. However, there is a lack of such uniformly abided by industry standards among various industries, so there is also a problem of interoperability.
(3) Business diversity: For users themselves, NFC services are a good bridge between users’ real life and virtual life, and users’ real lives are often not restricted by regions and industries.
