Like Bank of Communications, cardholders are not allowed to swipe their cards excessively. Bank of Communications credit card holders can only swipe their cards within the credit card overdraft limit, but if the cardholder's credit card limit is not enough, they can apply for increasing the temporary limit. Generally, the temporary limit can only be used for one period, and the original limit will be automatically restored in the next credit card billing cycle, and the cancelled temporary limit needs to be paid off by the cardholder in one lump sum.
