Shanghai Metro can use the "MetroMetropolis" software, WeChat and Alipay's subway code applets. Just scan the code and take the subway. Or you can buy a one-way ticket for the Shanghai Metro directly on WeChat, then scan the code to take the subway. In this case, you need to pay a certain deposit, which will be returned if not used. If your phone has NFC function, you can pay directly with a credit card.
What is the best way to take the subway in Shanghai every day? It depends on the individual situation to analyze and judge. If you simply take the subway, it will be more advantageous to choose a metropolitan city. However, you must not participate in discounts for bus and rail transit transfers, and you cannot use it while taking the bus, so the scope of use of this method in metropolitan areas will be limited.
If you not only need to take the subway, but also need a bus card, it will be more favorable to buy a subway card in this case. As long as it is within the opening range, after paying the fare with a subway card, passengers can transfer to other buses or subways within 120 minutes and only need to pay one yuan. If the senior card already enjoys discounts, you cannot enjoy the one-yuan discount.
In fact, most electronic payment methods now often offer various promotions. If you often need to travel by bus or subway, you can pay more attention to these preferential policies, which can effectively save some bus transportation costs to a certain extent.
