There is a computer that can read your electronic pass or ticket and are able to take the money from you or make sure that you have paid in order to use that road.
So, if you order something on the internet, you might get a confirmation to say " We've received your order, we've received your payment, we are going to deliver your order, we are sending it."
因此,如果您在 Internet 上订购商品,您可能会收到一条确认消息:“我收到您的订单, 我收到您的付, 我将交付您的订单, 我正在发送。
" To track (track) orders" means to make sure you know what's going on with the order at all times – whether it was paid for, whether it was shipped – that is, whether it was sent to the person who bought.
