Agricultural Bank of China supports the fixed limit of 20% for credit cards, that is, if the fixed limit is 10000 yuan, users can use the limit of 12000 yuan at most, but this limit can only be used when users pay by credit cards. Credit card cash advance does not support the excess part. In addition, 5% of the credit card exceeds the fixed limit as the over-limit handling fee, and the amount exceeding the fixed limit can also enjoy interest-free repayment.
