China 2.0

I came back to Shanghai recently. The point which surprised me the most since my first visit ten years ago, in 2007, was the massive use of QR codes. Actually when I landed in China, a guy was giving small papers with QR codes. They look a kind of visiting cards to my eyes. Welcome to China 2.0.

They are in everywhere. This together with the use of Wechat creates a digital scenario where nobody uses real money. Even money is not accepted in some shops.

Street vendors use this technology and save a lot of time. It's much more hygienic. Better for everyone.

It's also used for publicity, etc. I suggest placing a QR code in Mao's forehead, in his official portrait, linked to his red book or whatever other lectures.
