Alipay, China’s large-scale electronic payment platform, which had applied its blockchain technology to the “Singles’ Day” shopping festival has recently expanded its application scenarios to the Chinese subway. Alipay focuses on the area of ticket settlement between cities, allowing subway companies in each city to obtain the corresponding fare and other data on the blockchain to achieve an automatic settlement.
According to Chinese media “Interface News” report, Alipay has applied blockchain technology to subways in major cities in the Yangtze River Delta, including nine Yangtze River Delta cities: Shanghai, Nanjing, Hangzhou, Hefei, Ningbo, Wenzhou, Suzhou, Wuxi and Xuzhou, while the cities outside the district are Xiamen and Qingdao, a total of 11 cities. Shanghai Metro predicts that Changzhou and Lanzhou will join in late December this year to promote the development of two-dimensional code integration of national railway transportation.
Alipay technical expert Wei Shang pointed out that the biggest problem with inter-city transportation is the settlement of off-site tickets. Because the blockchain is immutable, it can record all inter-city transportation transactions, enabling metro companies in all cities Get relevant ticketing information. This is the first time that blockchain technology has been applied in China’s subway sector. When passengers ride the subway, as long as they use the mobile phone app of their city subway, they can use the QR code to enter the gate in other cities.
