The interconnectivity of metro QR code will be made available in the Yangtze River Delta after the successful experience in Shanghai, Suzhou and Wuxi. According to Tao Jie, head of information with Wuxi Metro Group, Shanghai Metro's gates have a data write-back function. You need to turn on the Bluetooth function of your mobile phone. This makes it easy for everyone to take the metro ride. The service will be available in other cities in the Yangtze River Delta, including Hefei, Ningbo and Changzhou where the metro app will be launched soon. Other cities in the Yangtze River Delta will follow suit.
