The software I chose was WeChat, which was originally designed by Zhang Yong, which was then named “WeChat” by Ma Huateng and released to the public through Tencent Group.
I didn’t find the original patent documents of WeChat on the Internet, but I found some patent documents about some special interaction methods of WeChat, one of which is “QR code anti-counterfeiting and anti-channel conflict query system and method based on WeChat platform” because There are many QR codes using WeChat, including payment QR codes. If the QR code is stolen, people can use the stolen QR code to pay for many things, and because WeChat payment can be bound to a bank card, This is very dangerous. The method mentioned in the article is to update the previous fixed QR code to one that can be refreshed regularly. The person who wrote this patent article is Xu Wen.
The initial release time of WeChat was January 17, 2011, the original company’s Beijing Cultural Communication Co., Ltd. The software can be installed on mobile phones, computers, tablets, and electronic watches. is software on removable electronic products.
