Transport cards make it easy to take the subway and buses in Chinese cities. But every time we go to a new city, we have to buy a new transport card for that city. But that will change in the near future. On March 29, the ministry of transport (MOT) announced that a nationwide transport card called T- union will be available for use in 220 cities across the country by the end of this year. By 2020, the card will be usable in all cities and towns nationwide. The MOT started the T-union project in 2013 to improve links between cities and rural areas. With a T-union transport card, you will be able to take public transportation like subways, buses, ferries, and taxis anywhere in China, the Xinhua news agency reported. The T-union card is currently being used in 119 cities, according to CCTV news, there are 30 million cars being used in several areas, such as the Yangtze River Delta. Cities that use the card included Shanghai, Guangzhou, Shijiazhuang ,Luoyang, and Qingdao. The T-union card will encourage more people to use public transportation. That's reducing the amount of pollution that is created by personal vehicles. It will also make it more convenient to travel around China, according to the people's daily. The MOT has made other try encouraging more people to take public transportation. For example, in cities like Beijing, Shanghai, and Hefei, people can board the subways or buses simply by swiping their mobile phones.
