RMB, which is the most inseparable in our life, has been issued since 1948 for more than half a century, and its position in our daily life is needless to say

It is estimated that friends who pay more attention to mobile phones will find that many high-end flagship computers are equipped with a function called NFC, and use it as one of the publicity stunts of mobile phones. But in our daily life, we seldom encounter the places where we have to use NFC, so what is NFC? What are its usage scenarios? How to develop in the future? Now let's give you a good introction

what is the future development prospect of NFC? Now the biggest limitation to NFC is the cost. This does not mean that NFC chips are too expensive, but that there are too few devices and scenarios supporting NFC. For example, now everyone is very accustomed to mobile payment, and even the hawkers on the street have Alipay and WeChat's two-dimensional code. They can be used simply after printing, and the cost is very low. How about NFC payment instead of this scenario? Then these vendors need to buy at least one POS machine, which is too expensive. If NFC wants to be as popular as mobile payment, then a large number of b-end devices can not be less, which involves the cost problem, otherwise businesses are not interested in helping to promote. However, with the arrival of 5g, the Internet of things has become the future development trend. Coupled with the recent fire of digital currency, it is likely to bring many revolutions in NFC technology. As long as the cost can be reced, NFC will be popularized one day. Generally speaking, we don't need to pursue NFC when we buy mobile phones. At present, the symbolic meaning of this function is greater than the actual meaning, and it doesn't deserve too much attention
