The number of swipes by the same card exceeds the limit, which means that the number of swipes by the credit card on the same pos machine is too many, which exceeds the upper limit stipulated by the bank. Once this happens, it will be forbidden to swipe your card. This is the bank's risk control behavior on credit cards, in order to prevent cardholders from cashing out. In addition, after exceeding the maximum limit of a single credit card or the maximum limit of the day, it will also be prohibited to swipe the card.
