https://hacker.bz/t/entry/2485-title-simply-implement-scan-and-connect-to-wifi/

If you are an individual business owner, which type of income is several hundred thousand yuan per year? When someone comes to the store, do customers often ask you what your Wi-Fi password is? Basically ask one question. And you will also say "use the master key to connect, or use the password to view it yourself." The experience was extremely unpleasant! In order to improve efficiency, thinking about allowing them to connect to Wi-Fi by themselves, TX has launched WiFi connections before. Is there any simpler way?

Existing Problem Analysis

Avoid the embarrassment of asking for Wi-Fi password as soon as the customer comes in. I don’t know letters for special groups such as the elderly. It's too troublesome to post the password to the wall, manually enter it.

WeChat WiFi connection

For WeChat WiFi connection, it is relatively commercialized. The threshold is relatively good, you need to apply for a WeChat official account and authenticate it, and you also need router support. All ordinary small shops are not necessary.

After thinking about it, let’s use the QR code that the Chinese people are accustomed to to solve this problem.

Pros and cons analysis

First of all, WeChat does not support scanning codes to connect to Wi-Fi, which is the biggest disadvantage, but fortunately, Alipay supports this function. Then we can let users use Alipay to scan the code.

At the same time, most mobile phones can now use the scan of the phone itself to connect to WIFI.

The production is also simple, we only need to create a QR code containing WiFi information.

WIFI:T:WPA; S: name; P: password; H:false; For example, the name is Xiaoyaozi's cousin-5G password bbskali.cn, it is

WIFI:T:WPA;S:Xiaoyaozi's cousin-5G;P:bbskali.cn;H:false;Copy the code, open the forage QR code generator, and generate the text QR code.
