1. Most banks have set a limit for automatic repayment of savings cards across banks. Savings cards of different banks have different repayment ceilings. Most of them are single transfers with a maximum limit of 50,000 yuan, and the daily cumulative amount does not exceed 50,000 yuan.

2. If the amount that the credit card holder needs to repay is higher than the upper limit, it is best to choose repayment channels such as bank counter, mobile banking, online banking or Alipay.

3. Automatic inter-bank repayment with a savings card is generally not real-time. In order to avoid the trouble of overdue repayment, it is recommended that the cardholder bind the savings card to repay two or three days in advance.

4. Even if the automatic repayment is bound to the savings card, it is best to check whether the repayment is successful 2~3 days before the "last due repayment date" to avoid leaving a stain on the credit record.

5. Generally, after the cardholder pays off the bill, the bank will send a text message "Your personal credit card account × monthly bill has been paid off". If you don't receive the SMS, you need to quickly check the repayment results.
