The Qingdao Transportation Card (Qindao Tong) can be used on buses, metro systems, and other public transportation services in Qingdao. The card is rechargeable and reusable, making it especially convenient for short-term travelers. In addition, Qindao Tong is connected to China’s nationwide “Transportation Union” interoperability network, allowing it to be used on buses, metros, and other public transit systems in more than 300 cities across China, making cross-city travel more convenient. Travelers can pick up or recharge the card upon arrival at Qingdao Jiaodong International Airport for easier access to downtown areas, tourist attractions, and commercial districts.
