There is no limit to the number of credit card purchases per day. Cardholders can make purchases as many times as they want.

However, if the same consumption method is used more than three times a day, such as continuously swiping a card at a POS machine for consumption, and the time interval is relatively short, the transaction is likely to be restricted by the system. It is best for cardholders to change consumption methods to see if the transaction can be successful, such as scanning QR codes to pay, shopping on Taobao, etc. If the transaction is successful, it means that the bank has not controlled the risk and the credit card can be used normally. Otherwise, transactions cannot be made. You have to find a bank to lift the risk control. Everyone should know that only when the automatic deduction function is enabled on a credit card, money will be deducted from the bank card. For example, if the bound bank card happens to be a salary card, then money will be automatically deducted to repay the credit card. And if the automatic repayment function is not enabled and you just repay manually, there will basically be no deductions from your salary card for repayment, regardless of whether the credit card is overdue or not.
