if there is an ETC card, it is basically deducted directly from the card, and there is no need to pay in cash. There are mainly two kinds of ETC cards: credit card and stored-value card

① Credit card: the owner doesn't need to recharge the ETC card, because ETC is bound with credit cards, which are all charged after passing. If there is not enough savings in the credit card, the system will automatically deduct it from the limit. Car owners remember to pay back in time, otherwise they will leave a bad credit record.

② stored value card: the main function of stored value card is basic transfer, but it does not have the function of overdraft. Just like the calling card of a mobile phone, you can make a phone call only if you have money. The stored value card can only pass if there is money in the card. Car owners need to recharge their stored-value cards in time, so as not to delay time and affect their mood on the expressway.
