Credit cards can be swiped unlimited times a day, but only if the accumulated credit card amount is within the credit card limit.

One thing to note is that even if the credit card has exceeded the fixed limit, many banks will still provide a small amount of overdraft limit, but at the same time they will also charge a 5% handling fee for the excess part. That is to say, every time the credit card exceeds the fixed limit of 100 yuan, 5 yuan handling fee will be charged.
