If the landlord's credit card bid is successful, you can keep the card temporarily closed and open it when necessary, because the bank will not charge you an annual fee unless you open a new card. At the same time, if the landlord needs to use it again in the future, it is ok to open it within the validity period of the card (the validity period of the card is on the front of the card, at the lower right of the card number, with four numbers, including a slash, in the form of "month/year". For example, if it is written as 12/ 18, it means that it is stuck at 18. After the expiration date, the card will be invalid, and you will not be replaced if you don't open the bank. )

In addition, the ETC function of Sanqintong Card can bring a lot of convenience to car owners. Even if it is opened, although the annual fee is 160 yuan/year, it will be reduced if you spend money by credit card or withdraw cash (unlimited amount) every year. Among them, general online transactions, telephone authorization, physical store credit card, cash withdrawal and so on. They all meet the requirements of annual fee reduction, so eating a meal, going shopping, visiting a supermarket and buying something online are usually done inadvertently.
