In fact, many retail stores in the world's second most populated country don't have credit card machines.

实际上，在这个世界人口第二大国，许多零售店没有信用卡刷卡机。

The pump is working but the credit card machine is not.

水泵在工作，但刷卡机不工作。

That's swiping your card, when you take your card and put it through a credit card machine.

这就是刷卡，当您拿起卡并将其放入信用卡机器时。

Well, that is not very convenient for people, so most gas stations have credit card machines on the pump itself.

嗯， 这对人们来说不是很方便，所以大多数加油站的泵本身都有刷卡机。

Each pump at the gas station has its own credit card machine that you can use so that you don't have to go inside the building in order to pay.

加油站的每个泵都有自己的刷卡机，您可以使用它，这样您就不必进入建筑物内即可付款。

In this case, it says that the customer has " to pay inside." So, what is out of order, what is not working, is the credit card machine that you can buy your gas from.

在这种情况下，它表示客户必须“在内部付款”。因此，出现故障、无法正常工作的是您可以从中购买汽油的信用卡机器。
