Usually credit cards have a fixed limit and a cash withdrawal limit, and the cash withdrawal limit is configured according to 50% of the credit card limit.

For credit card overdraft withdrawals, in addition to the cash withdrawal handling fee (0.5% of the cash withdrawal amount, at least 2 yuan), starting from the day of withdrawal, an interest of 0.05% of the cash amount will be charged every day. The maximum withdrawal limit for each card is 2,000 yuan, and the cumulative cash withdrawals shall not exceed half of the credit card limit.
