If you follow the original operation, you need to find Alipay or WeChat after entering the mobile phone desktop, and then click the program to find the corresponding health code option. In contrast, integrating the health code into the negative screen can reduce many unnecessary steps, especially for elderly elders, who often forget the location of the health code after entering Alipay or WeChat, and often need to waste some time to complete it. Of course, there are also mobile phones that support long pressing the Alipay icon to quickly jump out of the health code function path, or directly put the Alipay desktop plug-in on the negative screen.
