First of all, you should understand that credit cards are not debit cards, so don't mix them. Saving money in a credit card is different from a debit card. No matter how much money you deposit in a credit card and how long it lasts, there is no interest. Not only that, if you want to withdraw the money from the deposit, most banks will charge an overpayment to get back the handling fee.

The so-called overpayment refers to the overpayment of funds by credit card users or the funds deposited in credit card accounts, and a certain fee must be paid when they take them out. Simply put, there are some deposits in the credit card that exceed the bills that should be repaid, and there is a charge for taking them out.

Although credit cards can save money, it's best not to deposit money in credit cards, or you will have to deposit money in credit cards.

Therefore, it is strongly recommended that you never deposit money in it unless you have to, so as to save the trouble of withdrawing money in the future.
