Two thousand four hundred and ninety-nine: this is the number of people that participated at this giant project. Helping themselves with red and white umbrellas they “drew” a giant QR code. The initiative is called “Two Dimension Code” and the code actually works.. from an helicopter. On April 28 Coca-Cola in Zhengzhou City, China set a new world record “human” QR Code of 2,503 square meters (approx 27,000 square feet) when 2,499 employees and their families held up their red and white umbrellas (images below). The four Chinese characters in the center of the QR Code translate as “I love my family” which is the company slogan for the local Coca-Cola enterprise. The QR Code itself resolves to a download of WeChat, the predominantly Chinese mobile text and voice messaging communication service with over 355 million active users.
