Download a Beijing subway app. Some mobile phones have direct charging function. Open it and you can see the direct binding credit card recharge! Without this function, there is also a Lacarra address in it! Charge with Lacarra! However, some of them can't be prosecuted in Lacarra. You have to find a phone as big as a landline to charge it, and the card should be magnetic! My card will not work in ten years! ICBC atm can be recharged directly. I wonder if it can be recharged directly without ICBC credit card.
