First, it can greatly speed up the inspection of epidemic situation and the operation speed of public transportation. We can look at Baidu Encyclopedia's explanation of NFC first.
Near Field Communication (NFC) is a new technology. Devices using NFC technology (such as mobile phones) can exchange data when they are close to each other.
In fact, NFC is a short-distance communication method, which is especially similar to our credit card swiping. It is a convenient and quick form of bus card, but all this information is stored in the mobile phone for NFC transfer, and this popular form of credit card swiping in NFC can save the process very well, from the initial three steps of opening Alipay or WeChat, scanning the code and showing it, and even the time of waiting for the picture to be loaded, it is directly reduced to the step of swiping the mobile phone.
Second, for the elderly and children, NFC epidemic prevention punching means more convenient possibilities, which can reduce their troubles in life. Many elderly people don't use mobile phones to scan codes at all, or even want to use them, so they are stubborn. Many children know how to use it, but parents don't want them to carry their mobile phones every day. Moreover, this NFC technology can be used in the form of phone watches or other smart devices, and it can achieve the purpose of 100% prevention and control without complicated code scanning process, especially for the elderly, which is a very convenient invention.
I hope this NFC epidemic prevention punch card can be popularized as soon as possible, and everyone's life can be a little easier!
