According to Alipay, Alipay’s “Different Scanning Code” technology has been successfully applied to the “Transformation and Interconnection of Major Cities in the Yangtze River Delta” projects in Shanghai, Nanjing, Hangzhou, Hefei, Ningbo, Wenzhou and Suzhou. Residents pass through the 7 cities, just open the subway app in their city, and scan the car in the other 6 cities. Ant Xian Jin, chairman and CEO of Ant Financial, said that Alipay's remote scanning code technology has become a replicable sample of regional transportation integration. In the next year, Alipay will help all metro cities in the Yangtze River Delta to achieve cross-provincial inter-provincial communication, and gradually move toward “National Communication”. In addition, Alipay said that the “One Netcom” small program in the Yangtze River Delta was also piloted by Alipay. The courts of Shanghai, Hangzhou, Hefei and Suzhou jointly signed the “Intention Letter of Cooperation in the Yangtze River Delta Judicial Chain” with the ant blockchain, and used the ant blockchain technology to create a judicial-level trust mechanism.
