The card swiping mechanism of Beijing all-in-one card needs to swipe the card twice. There are two methods:
1. If you take the same bus in the same place, for example, if you do route 21, you need to wait for the next route 21 and brush it. You won't deduct more money;
2. When you take the bus again, there will be two or three beeps when you swipe your card on the bus. At this time, you will deduct the money for the whole journey last time. At this time, it is equivalent to that you have swiped your card on the bus. Remember to swipe your card normally when you get off the bus.
Note: in case of similar situations, the best way is to ask the ticket sales staff. What you find online is not necessarily correct!! Remember, if you forget to swipe your card when you get off the bus last time, swipe it once when you get on the bus again (the last money will be deducted), and be sure to swipe it again when you get off the bus.
