Generally speaking, it is impossible to increase the credit card deposit amount, because the credit card amount is mainly determined according to the applicant's income and card use habits. In other words, if you have a good income, real estate and automobile production, then you will get a high credit line, and vice versa. However, the special cards of individual banks can withdraw money in this way. For example, some banks have introduced zero-limit credit cards, requiring cardholders to save money before spending. However, with the increase of consumption, the overdraft limit will be automatically upgraded, which may be thousands of dollars after a long time.

In addition, cardholders will also enjoy preferential discounts when using zero credit cards. There is no handling fee for deposit and withdrawal, but an annual fee is required.
